Before MAYER, LOURIE, and RADER, Circuit Judges.

Opinion for the court filed by Circuit Judge LOURIE. Dissenting opinion filed by Circuit
Judge RADER.

LOURIE, Circuit Judge.

      Appellants (collectively, “EchoStar”) appeal from the district court’s decision

finding them in contempt of the court’s permanent injunction order. TiVo Inc. v. Dish

Network Corp., 640 F. Supp. 2d 853 (E.D. Tex. 2009). Because we find that the district

court did not abuse its discretion in imposing sanctions against EchoStar, we affirm the

finding of contempt.
                                     BACKGROUND

       TiVo, Inc. (“TiVo”) owns U.S. Patent 6,233,389 (“the ’389 patent” or “TiVo’s

patent”), which is entitled “Multimedia Time Warping System.” The patented technology

allows television users to simultaneously record and play (“time-shift”) television

broadcasts using what is commonly known as a digital video recorder (“DVR”). A DVR

allows users to fast-forward, rewind, pause, and replay a “live” television program while

it is playing on the television set. TiVo’s patent covers various features essential to the

working of a DVR.

       In 2004, TiVo sued EchoStar in the United States District Court for the Eastern

District of Texas, alleging that its receivers infringe “hardware” claims (claims 1 and 32)

and “software” claims (claims 31 and 61) of the ’389 patent. The hardware claims are

not at issue in this appeal.

       Claim 31 of the ’389 patent is the first of the two software claims. It provides as

follows:

       A process for the simultaneous storage and play back of multimedia data,
       comprising the steps of:
             [1] providing a physical data source, wherein said physical
             data source accepts broadcast data from an input device,
             parses video and audio data from said broadcast data, and
             temporarily stores said video and audio data;
             [2] providing a source object, wherein said source object
             extracts video and audio data from said physical data
             source;
             [3] providing a transform object, wherein said transform
             object stores and retrieves data streams onto a storage
             device;
             [4] wherein said source object obtains a buffer from said
             transform object, said source object converts video data into
             data streams and fills said buffer with said streams;
             [5] wherein said source object is automatically flow
             controlled by said transform object;
             [6] providing a sink object, wherein said sink object obtains

2009-1374                                   2
              data stream buffers from said transform object and outputs
              said streams to a video and audio decoder;
              [7] wherein said decoder converts said streams into display
              signals and sends said signals to a display;
              [8] wherein said sink object is automatically flow controlled
              by said transform object;
              [9] providing a control object, wherein said control object
              receives commands from a user, said commands control the
              flow of the broadcast data through the system; and
              [10] wherein said control object sends flow command events
              to said source, transform, and sink objects.

       Claim 61 is similar to claim 31, except that it recites an apparatus rather than a

process.

       The accused EchoStar receivers can be broadly classified in two categories

based on the processing chip employed by the receiver: the “50X” series and the

“Broadcom” series.    The jury found that both the 50X receivers and the Broadcom

receivers infringed the asserted hardware as well as software claims and awarded TiVo

approximately $74 million in lost profits and reasonable royalties. The district court

entered judgment on the verdict and issued a permanent injunction against EchoStar.

In granting the injunction, the district court ordered EchoStar (1) to stop making, using,

offering to sell, and selling the receivers that had been found infringing by the jury (the

“infringement” provision) and (2) to disable the DVR functionality in existing receivers,

with the exception of select receivers that had already been placed with its subscribers

(the “disablement” provision).

       Following the entry of final judgment by the district court, we affirmed in part,

reversed in part, and remanded the district court’s decision. EchoStar had appealed

issues of claim construction and infringement to us. We found that the district court had

incorrectly construed at least one limitation of the hardware claims and reversed the

2009-1374                                   3
portion of the judgment upholding the jury’s verdict that EchoStar’s DVRs literally

infringed the hardware claims. TiVo, Inc. v. EchoStar Commc’ns Corp., 516 F.3d 1290,

1304–05 (Fed. Cir. 2008). However, we found no error in the district court’s claim

construction of the software claims and also affirmed the jury’s verdict that the EchoStar

devices infringed the software claims of the ’389 patent. Id. at 1310.

        At that time, EchoStar did not appeal the district court’s grant of a permanent

injunction. In our opinion, we noted that the district court’s injunction, which had been

stayed during the course of the appeal, would take effect following our decision. Id. at

1312.       We advised the district court that it may make a determination as to any

additional damages that TiVo may have sustained while the stay of the permanent

injunction had been in effect. Id.

        Following the decision on the appeal, TiVo moved the district court to find

EchoStar in contempt of the court’s permanent injunction. After conducting a series of

hearings on TiVo’s motion, the district court ruled that EchoStar was in contempt of its

earlier order. The district court rejected EchoStar’s argument that it had redesigned its

infringing products so that they were more than colorably different from the adjudged

infringing devices. The district court evaluated two of EchoStar’s major modifications to

the infringing DVR software and concluded that the modified software continued to

infringe.     The district court therefore found EchoStar to be in violation of the

infringement provision of the injunction. Moreover, the district court found that even if

EchoStar had achieved a noninfringing design-around, EchoStar would still be in

contempt because it had failed to comply with the disablement provision in the district

court’s order requiring it to disable DVR technology completely from the receivers

2009-1374                                   4
adjudged to be infringing at trial. For EchoStar’s contempt of the court’s order, the

district court imposed sanctions against EchoStar in the amount of nearly $90 million.

TiVo Inc. v. Dish Network Corp., 655 F. Supp. 2d 661, 666 (E.D. Tex. 2009). The court

also awarded damages to TiVo for the continued infringement by EchoStar’s redesigned

software. Further, the court amended its earlier injunction, requiring EchoStar to seek

the court’s approval before implementing future noninfringing workarounds to its DVR

software.     EchoStar now appeals.       We have jurisdiction pursuant to 28 U.S.C.

§ 1295(a)(1).

                                       DISCUSSION

   A.        Contempt of the Infringement Provision

        1.      Contempt Proceeding

        We have held that a district court must make a two-part inquiry in finding a

defendant in contempt of an injunction in a patent infringement case.          See KSM

Fastening Sys., Inc. v. H.A. Jones Co., 776 F.2d 1522, 1530 (Fed. Cir. 1985). First, the

court must determine whether a contempt hearing is an appropriate forum to adjudge

infringement by the redesigned product. Id. at 1532.        The court may do this by

comparing the accused product with the original infringing product to determine if there

is “more than a colorable difference” between the accused product and the adjudged

infringing product such that “substantial open issues with respect to infringement” exist.

Id. Where the court finds that to be the case, a new trial is necessary to determine

further infringement and the court may not proceed with a contempt finding. Id. Only in

cases where the court is satisfied on the threshold inquiry of forum appropriateness can

a court inquire whether the redesigned product continues to infringe the claims as

2009-1374                                    5
previously construed by the court. Id.

       EchoStar argues that it was impermissible for the district court to try issues

relating to continued infringement by EchoStar’s modified software in a contempt

proceeding. According to EchoStar, its modifications to the infringing DVR software

were so substantial that TiVo should have been required to litigate its claims over the

modified software in a separate infringement action.

       EchoStar contends that it undertook a Herculean effort in redesigning the DVR

software in its receivers so that it would no longer infringe the software claims in TiVo’s

patent. Primarily, EchoStar claims that it removed at least two key infringing elements

from the software in its Broadcom series receivers: video and audio data parsing, and

automatic flow control.     Regarding the first modification, EchoStar claims that it

eliminated the parsing feature which was useful in creating an index of “start codes” of

the audio and video data.      That index enabled “trick play” operations.       The new

EchoStar DVR software is therefore “indexless” and performs those operations through

a “brute-force” method, utilizing average frame rate statistics to estimate the location of

any video data. With regard to the second modification, EchoStar claims that its earlier

software made use of a “record buffer” in addition to a pool of ten transport buffers. The

record buffer acted as intermediate storage for data being written to the hard drive when

each of the ten transport buffers was full. The record buffer also performed a “blocking”

function whereby data transfer from the transport buffers would be blocked until the

successful transfer of record buffer data to the hard drive.      EchoStar claims that it

removed the record buffer and redesigned its software to transfer data directly from the

transport buffers to the hard drive, thereby eliminating the blocking feature from its

2009-1374                                   6
Broadcom receiver software. For its 50X series receivers, EchoStar implemented only

the change to the indexing mechanism described above.

       According to EchoStar, the district court failed to recognize that the modified

components had completely transformed the infringing software. EchoStar argues that

the court misapplied the colorable differences test by failing to analyze the theories

upon which the jury had adjudged EchoStar’s software to be infringing.               EchoStar

argues that a contempt proceeding is only suitable where the adjudged infringer makes

nothing more than bad-faith cosmetic changes.             EchoStar presents a long list of

arguments as to why its redesigned software should be considered more than colorably

different. It argues that it removed features from its software that TiVo had previously

pointed to as infringing. In order to succeed, EchoStar contends, TiVo had to accuse

completely different components of its software and advance new infringement theories

with regard to the modified software. According to EchoStar, the fact that TiVo was

forced to contradict one of its positions at trial, and that the district court had to resort to

expert testimony in order to resolve the new infringement theory both show that the

changes were substantial.

       TiVo responds by arguing that EchoStar’s modifications are trivial.                TiVo

contends that the modified software comprises only a small fraction of EchoStar’s DVR

software. Moreover, TiVo contends, the modifications do not affect any element of the

two asserted claims.      TiVo also urges us to reject EchoStar’s proposition that its

modified software must be evaluated against the claims as adjudged by the previous

jury instead of the claims construed by the district court. According to TiVo, removing

infringing elements identified by it at the previous trial cannot ensure that EchoStar does

2009-1374                                      7
not infringe TiVo’s patent, or even guarantee a new trial as long as those changes do

not raise substantial open issues of infringement.    TiVo contends that none of the

modifications EchoStar made to its software presented the trial court with such open

issues.

      We review the district court's decision to proceed via a contempt hearing for

abuse of discretion. KSM, 776 F.2d at 1532. We conclude that the district court did not

abuse its discretion in finding that EchoStar’s modified software raised no substantial

open questions of infringement. As a threshold matter, we determine that the district

court used the proper standard in its analysis. EchoStar argues that TiVo had to prove

by clear and convincing evidence that a contempt proceeding was appropriate in this

case. We agree instead with the district court that, although TiVo was required to put

forth evidence that such a proceeding was appropriate, that question is left to the

discretion of the trial court to be answered under the analysis mandated by our decision

in KSM.

      With regard to the 50X series receivers, the district court found that the

modification made to remove indexing of start codes impacted only a single claim

limitation, namely, “parses video and audio data from said broadcast data.” The court

found that the change did not render the infringing software more than colorably

different because there was another feature of the software that continued to meet that

limitation. The court noted that EchoStar’s own experts had testified at trial that “PID

filtering,” a mechanism designed to distinguish between various television programs,

satisfied that limitation. Moreover, the court noted, EchoStar’s own engineers referred

to PID filtering as “parsing,” and EchoStar’s own internal documents referred to the

2009-1374                                  8
modified software as “Indexless DVR and TS Parsing.”               Given that EchoStar’s

modification impacted only one limitation, one that it had already conceded was

infringed by another software component, the court concluded that the adjudicated and

modified products were not more than colorably different.

        We agree with the district court that no substantial open questions of

infringement remained to be resolved through a trial on this modification. The district

court did not err when it looked to other components that EchoStar had itself conceded

met the same limitation that was being claimed. In KSM, we stated that “the district

court is able to utilize principles of claim and issue preclusion (res judicata) to determine

what issues were settled by the original suit and what issues would have to be tried.”

776 F.2d at 1532. Here, there was ample testimony presented at trial regarding parsing

of data in EchoStar’s receiver software and whether it satisfied the parsing limitation.

Multiple experts for both TiVo and EchoStar had testified at trial that PID filtering was in

fact “parsing.”    EchoStar did not make any changes to its PID filter software

components. In light of such evidence, it was not an abuse of discretion for the district

court to conclude that EchoStar’s modification to its indexing software component had

not rendered its 50X receivers more than colorably different from the adjudged infringing

ones.

        We also reject EchoStar’s and the dissent’s argument that the district court was

required to limit its analysis to whether the modified devices had eliminated start-code

detection and indexing. EchoStar argues that a contempt hearing is proper only when

the redesigned devices are alleged to infringe in the exact same manner that has

already been adjudicated to infringe. We disagree. The test for colorable differences is

2009-1374                                    9
not divorced from the scope of the claim that has previously been found to have been

infringed. See Additive Controls & Measurement Sys., Inc. v. Flowdata, Inc., 154 F.3d

1345, 1350 (Fed. Cir. 1998) (evaluating only those changes that were relevant claim

limitations). Modifications that EchoStar made to its software based on what it alone

considered to be the basis of the jury’s infringement finding cannot guarantee the

creation of substantial open issues with respect to infringement. Where the court is

clearly convinced, based on evidence presented at trial, that there are no substantial

open issues on continuing infringement of the asserted claims, we see no reason to

disallow summary proceedings. See KSM, 776 F.2d at 1532 (citing MAC Corp. of Am. v.

Williams Patent Crusher & Pulverizer Co., 767 F.2d 882, 885-86 (Fed. Cir. 1985)) (“So

long as the district court exercises its discretion to proceed or not to proceed by way of

contempt proceedings within these general constraints, this court must defer to its

judgment on this issue.”); see also Additive Controls, 154 F.3d at 1350 (holding that

within the general constraints stated in KSM, the district court has broad discretion to

determine how best to enforce its injunctive decrees). EchoStar’s proposed standard

would make it almost impossible for a district court to employ a contempt proceeding to

enjoin infringing products. Compelling the parties to undertake a new trial every time

there is a dispute over previously adjudicated infringing products would fail to serve the

goals of judicial economy. We disagree with the dissent that a new trial is necessary

here for the parties to reargue an issue – the operation of the exact same PID filter –

that has now been argued multiple times to the district court.

      For the same reasons, we conclude that the district court did not err in finding

only colorable differences between the adjudicated Broadcom receiver software and the

2009-1374                                   10
modified one. For its Broadcom receivers, EchoStar implemented a software change

eliminating a record buffer in addition to the start code indexing modification discussed

above. The district court found that the additional change affected only the automatic

flow control claim limitation.   The court found that both the modified and original

products operate a circular transport buffer structure with ten buffers within the

structure. The court concluded that in essence the buffer modification was nothing

more than a change from eleven buffers to ten.

      We agree with the district court that that was not a major redesign of the

software. EchoStar seeks to magnify the significance of its buffer redesign by arguing

that the modifications resulted in skewing of the infringement mapping asserted by TiVo

at trial, thereby requiring TiVo to remap each claim limitation against different

components of the software. That, EchoStar argues, mandates a new trial. However,

EchoStar did not significantly change the manner in which data flows to the transport

buffers, simply the manner in which it is written to the hard disk. The district court was

familiar with the operation of the prior infringing software, and properly determined that

EchoStar’s change primarily impacted the manner in which automatic flow control was

achieved. Moreover, we have made clear that the presence of a new issue does not

necessarily preclude the district court from making use of a contempt proceeding to

determine continued infringement.     See Additive Controls, 154 F.3d at 1350 (“The

presence of a new issue, however – even a new issue of claim construction – does not

necessarily require that a separate infringement action be brought to determine whether

the accused device infringes the patent in suit.”). In Additive Controls, we upheld a

district court’s decision to proceed with contempt proceedings where the court had to

2009-1374                                  11
conduct claim construction prior to determining whether the variations were more than

colorably different from the infringing products. Id. We held that the district court’s

determination (via a contempt proceeding) of infringement by the modified devices and

based on its new claim construction was not an abuse of discretion. Id. We therefore

conclude that the court did not abuse its discretion in finding that the Broadcom receiver

software had not been altered significantly enough to raise substantial open issues of

infringement.

       Finally, we reject EchoStar’s argument that evidence of its good faith suffices to

protect it from any finding of contempt. EchoStar argues that it paid 15 engineers to

spend 8000 hours on the redesign, which took a year. Similarly, it stresses the fact that

it obtained an opinion of noninfringement from a respected patent law firm. It further

contends that the redesign compromised performance in order to avoid infringement of

TiVo’s patent, giving it a product inferior to what it previously had.       In light of this

evidence, EchoStar argues, the district court was prohibited from utilizing a contempt

hearing in this case.

       We disagree and conclude that EchoStar misreads our law. Although we have

acknowledged that good faith may be an indicator that redesigned products are more

than colorably different, Arbek Mfg., Inc. v. Moazzam, 55 F.3d 1567, 1570 (Fed. Cir.

1995), we have also made it clear that a lack of intent alone cannot save an infringer

from a finding of contempt. Additive Controls, 154 F.3d at 1353 (“The general rule in

civil contempt is that a party need not intend to violate an injunction to be found in

contempt.”). It was clearly within the district court’s discretion to give appropriate weight

to EchoStar’s good faith arguments, but not to accept them.

2009-1374                                    12
        The district court has presided over this case for over five years.         Given its

familiarity with the parties, the patent at issue, and the infringing products, in addition to

the well articulated reasoning for its decision, we do not find an abuse of discretion in

the court’s decision to hold contempt proceedings.

        2.    Infringement of the ’389 Patent

        EchoStar argues that because TiVo failed to prove by clear and convincing

evidence that the redesigned devices infringe, it is not in contempt of the infringement

provision of the injunction.   With regard to the 50X series receivers, EchoStar argues

that at the very least, the claim limitation “parses video and audio data from said

broadcast data” is not met by its new software.           It argues that the district court

improperly found infringement based on the simple fact that the software includes a PID

filter that parses some data. The filter, however, EchoStar argues, looks only at the

header of a data packet, not the payload where the video and audio are contained.

Therefore, EchoStar urges, its modified software does not parse any audio and video

data.

        TiVo responds that the district court has previously construed the term “parses”

broadly to mean “analyzes,” a construction that has never been challenged, and all that

is required for the modified software to meet this limitation is a component that analyzes

video and audio data. TiVo argues that EchoStar’s attempt to differentiate header data

from the packet payload is improper because both are part of an MPEG packet, and the

whole packet is video and audio data. Moreover, TiVo argues that experts for both

sides testified at trial that PID filtering meets the parsing limitation under the court’s

claim construction.

2009-1374                                    13
       We review the district court’s finding of continued infringement and other

subsidiary factual findings made in a contempt proceeding for clear error. Additive

Controls, 154 F.3d at 1351. We may reverse a finding of infringement only if we are left

with a definite and firm conviction that a mistake has been committed by the trial court.

Unique Concepts, Inc. v. Brown, 939 F.2d 1558, 1564 (Fed. Cir. 1991) (citations

omitted).

       We have no such conviction here.            We agree with TiVo that there was

overwhelming evidence before the district court to find that the “parses” limitation was

met by the PID filter component. EchoStar’s own expert, Dr. Rhyne, testified at trial that

the infringing software contained PID filters “that examine the MPEG transport stream

and do a parsing.” At the contempt proceeding, Dr. Rhyne testified that the operation of

PID filters in the modified software had not changed since trial. As TiVo points out, the

PID codes in the packet headers are just as necessary to view television as the start

codes in the packet payload. More importantly, there is nothing in the claims or the

specification that requires audio and video data to be limited to specific fields of an

audio or video data packet in the context of this limitation.

       EchoStar argues that both parties have switched positions on this issue and

therefore that judicial estoppel prevents TiVo, the prevailing party, from taking a position

that is clearly inconsistent with its earlier position. We, like the district court, do not see

TiVo’s position on the PID filter component as being “clearly inconsistent” with the one

that it took at trial. See New Hampshire v. Maine, 532 U.S. 742, 750 (2001) (holding

that in order to invoke judicial estoppel, “a party’s later position must be ‘clearly

inconsistent’ with its earlier position”).    EchoStar does not point to any statement

2009-1374                                     14
wherein TiVo unequivocally denied that a PID filter can accomplish audio and video

parsing. On the contrary, TiVo points to several instances where it conceded the fact.

For example, at the summary judgment stage, EchoStar’s own counsel pointed out to

the district court that TiVo’s expert had agreed that PID filtering satisfies the parsing

limitation. Moreover, TiVo’s statements at trial regarding the PID filter were made in

connection with EchoStar’s infringement of the hardware claims.              Those claims

specifically required a “media switch,” which parses an MPEG stream, separating it into

its video and audio components. See ’389 patent, cls. 1, 32. As we noted in our earlier

opinion, the specification discloses in detail the parsing function that is claimed as part

of the media switch. TiVo, 516 F.3d at 1301–02. TiVo’s expert testimony at trial was

clearly related to infringement of that media switch limitation of the asserted hardware

claims.   In pursuing contempt against EchoStar, TiVo takes the position that the

operation of a PID filter in EchoStar’s software meets the parsing limitation of the

software claims. Although the general presumption is that the same claim term in the

same patent carries the same construed meaning, Omega Eng’g, Inc, v. Raytek Corp.,

334 F.3d 1314, 1334 (Fed. Cir. 2003), here, the scope of the software claims is indeed

very different from that of the hardware claims. We cannot agree with EchoStar that

TiVo’s current position on PID filtering is entirely inconsistent with its position at trial.

See Sandisk Corp. v. Memorex Prods., Inc., 415 F.3d 1278, 1291 (Fed. Cir. 2005)

(rejecting judicial estoppel arguments where the patentee’s earlier claim construction

position related to narrower term and the subsequent position was on a broader term).

The district court properly found that the PID filter in EchoStar’s modified software

“parses video and audio data” as required by the software claims.

2009-1374                                    15
       We now turn to the question of continued infringement by the Broadcom receiver

software wherein EchoStar implemented an additional record buffer modification.

Regarding the Broadcom software, EchoStar argues that the claims require that data

move through a specific set of software components in a specific order, and neither

TiVo nor the district court was able to map this flow within EchoStar’s redesigned

software. Specifically, EchoStar argues that following the removal of the record buffer

and related operations, its software no longer met claim limitations that require

extraction and conversion of data as well as filling of a buffer.       Further, EchoStar

argues, that with its new buffer design, the automatic flow control limitation is no longer

met. Specifically, EchoStar contends that by eliminating the “blocking” function that had

been alleged to provide automatic flow control, it completely removed this claim

limitation from its software.

       TiVo responds by arguing that EchoStar’s software cannot escape infringement

by the trivial change that it made. TiVo contends that all EchoStar did was to remove a

copy buffer that was available as a programming convenience, allowing programmers to

divorce themselves from the Broadcom driver code. TiVo contends that EchoStar’s own

engineers represented the modification as nothing more than the removal of an

intermediate buffer.    It points out that it provided detailed mapping of each claim

limitation against components of EchoStar’s modified software, complete with record

citations and specific examples of code, showing how the software continues to infringe.

Further, TiVo argues, its expert testified at the contempt hearing to infringement of each

of the claim limitations at issue.

       We are persuaded that the district did not clearly err in finding continued

2009-1374                                   16
infringement by the modified Broadcom receiver software.            We reject EchoStar’s

primary argument that TiVo’s new mapping of the modified software results in

noninfringement. According to EchoStar, under the new mapping, the “Input Buffer” on

the Broadcom chip is the “temporary storage,” and the “transport buffer” in RAM is the

“buffer.” Therefore, EchoStar argues, its software no longer extracts, converts, or fills

data as required by the claims, or at least not in the order required by the claims. For

instance, EchoStar argues that in the redesigned receivers, the buffer is filled not by

software but by hardware, namely, the Broadcom chip. We have previously rejected a

similar distinction between the operation of hardware and software proposed by

EchoStar.    See TiVo, 516 F.3d at 1309 (finding EchoStar’s hardware/software

distinction unhelpful because software alone cannot perform data extraction from a

physical device). The fact that the buffer is now filled by the Broadcom chip software

does not render EchoStar’s modified software noninfringing.         TiVo provided expert

testimony, along with exemplary code, on how the modified software satisfies each of

these limitations. TiVo further produced infringement charts showing how each of these

claim limitations continued to be met. Moreover, there was ample evidence presented

at trial by both parties to analyze the workings of EchoStar’s software. It was therefore

not improper for the district court to summarily find that each of the limitations continued

to be met in substantially the same manner as before. The court focused on the one

limitation that was clearly impacted by the modification, the automatic flow control

limitation. The court found that in spite of the redesign, several aspects of the software

continued to satisfy that limitation.   Before trial in this case, the district court had

construed “automatically flow controlled” to mean “self-regulated.” The court held that

2009-1374                                   17
such self-regulation is found in the ten buffers that the software uses in a circular

arrangement, rotating between buffers as each of them begins to fill. As TiVo points

out, the system ensures that under normal conditions the buffers are no more than 70%

full. The court looked to pointers and descriptors used by the software to manage flow

of data and concluded that those were all methods of self-regulation of data. The

claims do not require, and the court did not construe the claims to require, that data flow

be completely halted in order to achieve automatic flow control. We find that there was

clear and convincing evidence that the automatic flow control limitation was met.

        We also agree with TiVo that there is no inherent order required among the claim

limitations, and none has been argued before. We therefore conclude that each of the

claim limitations continues to be met by the modified Broadcom receiver software. We

are persuaded that there was clear and convincing evidence before the district court to

find that both types of EchoStar receivers continue to infringe and that it was not an

abuse of discretion for the court to find EchoStar in contempt of the infringement

provision.

   B.        Contempt of the Disablement Provision

        EchoStar argues that the district could not find it in contempt of a provision that,

when reasonably read, does not require it to do anything more than to change its DVR

software component.       EchoStar contends that it simply downloaded noninfringing

software to the receivers that it had placed with consumers. EchoStar argues that the

district court’s injunction cannot be read to prohibit such noninfringing design-arounds.

According to EchoStar, the plain language of the disablement provision contains two

distinct directives. EchoStar explains that the first clause, requiring disablement of “the

2009-1374                                    18
DVR functionality,” refers only to the functionality that previously existed and was found

to be infringing. EchoStar argues that because its modified software had not yet been

developed or installed in those receivers, the district court could not have ordered it to

disable functionality that did not exist.   EchoStar contends that the second clause,

requiring EchoStar not to enable the same infringing DVR functionality in future

products, confirms its understanding. EchoStar further argues that the district court, in

ordering that it “disable all storage to and play back from a hard disk drive of television

data,” had to mean that EchoStar was required to disable all infringing storage and

playback functionality.   Therefore, EchoStar argues, the district court erred when it

interpreted its injunction to require a permanent disablement of all DVR functionality in

the specified EchoStar units.

       TiVo responds that the district court was abundantly clear about what it meant by

the disablement provision.      According to TiVo, the order defines the term “DVR

functionality” and specifically lists the eight EchoStar models to which it applies.

Further, TiVo notes, the court emphasized what it meant by requiring disablement of “all

storage to and playback from a hard disk of television data” in the enumerated EchoStar

models. TiVo also contends that EchoStar had adequate notice of the meaning of the

injunction because EchoStar had argued to the district court that it should be allowed to

implement DVR functionality in the listed models in a noninfringing manner.              In

response, TiVo contends, TiVo had argued to the district court that all DVR functionality

in all EchoStar units should be disabled. According to TiVo, the district court rejected

EchoStar’s argument and adopted TiVo’s proposal for broader relief in order to prevent

mischief on the part of EchoStar.       TiVo argues that such broad injunctions have

2009-1374                                   19
previously been approved by this court. TiVo argues that in light of such clear notice,

EchoStar simply assumed the risk of a future finding of contempt by deciding to proceed

based on its own understanding of the order, without seeking further guidance from the

district court or appealing the injunction to this court. Therefore, TiVo argues, EchoStar

is barred from collaterally attacking the disablement provision now.

       A district court’s interpretation of the terms of an injunction or any other legal

instrument is a question of law that we review de novo. See Laitram Corp. v. NEC

Corp., 115 F.3d 947, 951 (Fed. Cir. 1997). Under the Federal Rules of Civil Procedure,

“[e]very order granting an injunction . . . shall be specific in terms [and] shall describe in

reasonable detail, and not by reference to the complaint or other document, the act or

acts sought to be restrained.” Fed. R. Civ. P. 65(d). Rule 65(d) “was designed to

prevent uncertainty and confusion on the part of those faced with injunctive orders, and

to avoid the possible founding of a contempt citation on a decree too vague to be

understood.” Abbott Labs. v. TorPharm, Inc., 503 F.3d 1372, 1382 (Fed. Cir. 2007)

(quoting Schmidt v. Lessard, 414 U.S. 473, 476 (1974)). We have held that a district

court cannot find a party in contempt of its injunction order where the party had no

explicit notice that it was enjoined from specific conduct. Id. at 1383. However, it is

also well established that where a district court has made clear its intent in barring

certain conduct, a party is not free to ignore the court’s order and only appeal a later

contempt finding. See Carborundum Co. v. Molten Metal Equip. Innovations, Inc., 72

F.3d 872, 883 (Fed. Cir. 1995) (finding no abuse of discretion in a district court

contempt finding where a defendant had failed to follow an injunction that the court had

clarified during the proceedings). The time to appeal such an order is when it is handed

2009-1374                                    20
down, not when a party is later found to be in contempt. Other circuits have also held

that the scope of an injunction may be challenged only on direct appeal. W. Water

Mgmt., Inc. v. Brown, 40 F.3d 105, 108 (5th Cir. 1994); accord John Zink Co. v. Zink,

241 F.3d 1256, 1260 (10th Cir. 2001) (finding arguments related to interpretation of an

injunction waived where the defendants had failed to raise them in their earlier appeal).

       We conclude that the district court’s injunction was sufficiently clear to bar

EchoStar from challenging it now.       The injunction expressly proscribes “the DVR

functionality” and further clarifies what it means by the term. The order clearly defines

the term “Infringing Products” prior to referring to it in the disablement provision. The

order then goes on to restate that “[t]he DVR functionality, storage to and playback from

a hard disk drive shall not be enabled in any new placements of the Infringing

Products.” EchoStar’s argues that this second sentence, because it references new

placements, requires that the term “DVR functionality” be read as referring only to

infringing software.

       We do not agree with the stretched reading of this provision that EchoStar

proposes. See Signtech USA, Ltd. v. Vutek, Inc., 174 F.3d 1352, 1359 (Fed. Cir. 1999)

(holding that where an injunction provides adequate notice of the conduct enjoined, the

specificity requirement of Rule 65(d) is served). “All” plainly means all. At a minimum,

EchoStar had notice of the possibility that the district court was imposing a complete

ban on the DVR software of each of the listed receivers. As TiVo points out, at the time

the district court issued its injunction, EchoStar’s receiver hardware had been found to

infringe the hardware claims as well, a finding that we later reversed. It would thus have

been reasonable for one to read the injunction when it issued as barring any

2009-1374                                  21
implementation of software similar to the one found by the district court to be infringing

in all of the hardware that was found to be infringing. We find it important to note that

the district court did not order a complete disablement or recall of the infringing

hardware. The DVR software is but one of many components of EchoStar’s receiver

software. The one piece of evidence that we do have of EchoStar’s understanding of

the disablement provision is its emergency motion for us to stay the injunction, in which

EchoStar repeatedly stated that the injunction would render millions of its customers

without DVR service or require them to go through considerable trouble and expense of

obtaining DVR service from another provider. The motion, filed even as EchoStar was

developing and preparing to roll out its workaround, in no way demonstrates EchoStar’s

contrary understanding of the disablement provision. As long as a plain reading of the

order would have provided EchoStar with notice of what it is now being held in

contempt, we cannot allow a collateral challenge to the order at this time.           See

Travelers Indem. Co. v. Bailey, 129 S. Ct. 2195, 2204 (2009) (barring a collateral

challenge to an order, regardless of its merits, where the issue could have been raised

on direct appeal).

       EchoStar raised a variety of issues including claim construction, infringement,

and various other trial rulings in its appeal from the district court’s prior judgment. See

TiVo, 516 F.3d 1290.      EchoStar even moved us to stay the permanent injunction

pending that appeal, and we granted a stay. EchoStar strongly protested the injunction,

detailing the potential damage it would suffer from the injunction in its motion to stay.

However, it failed to raise the issue on appeal. The fact that there were numerous other

issues on appeal cannot excuse its failure to appeal the injunction.       Had EchoStar

2009-1374                                   22
brought an appeal on the injunction, we could have addressed its legitimacy. The time

to do so has long passed. “It is just as important that there should be a place to end as

that there should be a place to begin litigation.” Travelers, 129 S. Ct. at 2206 (citations

omitted). We thus agree with the district court that EchoStar waived any argument that

the injunction was overbroad.

       The dissent argues that it would be completely improper for the district court to

find EchoStar in contempt of the disablement provision if the modified technology was

outside the scope of the asserted claims. While it is true that infringement is generally

essential for a violation of an injunction against infringement, KSM, 776 F.2d at 1528, it

is also settled law that as long as EchoStar had explicit notice of what it had been

ordered to do and had refused to do so, the court possessed broad equitable powers to

enforce its decree. See Abbott, 503 F.3d at 1383; see also KSM, 776 F.2d at 1524 (“A

civil contempt proceeding for violation of an injunction issued after patent litigation, while

primarily for the benefit of the patent owner, nevertheless, involves also the concept of

an affront to the court for failure to obey its order.”).

       The dissent suggests that under the trial court’s interpretation of the disablement

provision, in order to escape contempt, EchoStar was effectively required to go into

each of its customers’ homes and physically replace each cable box containing any

DVR functionality with an identical cable box with the same software. However, use of

identical boxes with the same software would be in contempt of the court’s infringement

provision. See Additive Controls, 154 F.3d at 1350, 1356 (affirming the district court’s

contempt finding where the redesigned products were manufactured by a successor

company and marketed under a different name). Regardless of its validity, which was

2009-1374                                      23
never before us, the district court’s disablement provision was clearly meant to prevent

EchoStar from providing DVR functionality on its receivers.

       In reading the disablement provision as applying only to infringing DVR software,

the dissent relies on the fact that TiVo acknowledged to the district court that EchoStar

could reprogram receiver software at its existing placements to disable the DVR

component within those receivers via satellite.       We find the manner in which the

disablement could be accomplished irrelevant to the issue at hand.              TiVo never

conceded to the district court that EchoStar should be allowed to replace the infringing

DVR software component (in its then-adjudged infringing hardware) with a potentially

noninfringing software component either via satellite or otherwise.           We find that

EchoStar had ample notice of what it had been ordered to do. Further, by adding a

separate provision on disablement and specifically defining what it meant by “DVR

functionality” in its order, the district court made its expectations sufficiently clear, and

more importantly fulfilled the requirements of Rule 65(d).

       Finally, we address EchoStar’s request that we vacate the district court’s recent

amendment to its injunction requiring EchoStar to inform the court of any further

redesign attempts and to seek preclearance before implementing a design-around. We

deny that request.

       Pursuant to 35 U.S.C. § 283, district courts are authorized to “grant injunctions in

accordance with the principles of equity to prevent the violation of any right secured by

patent, on such terms as the court deems reasonable.” We have repeatedly stated that

district courts are in the best position to fashion an injunction tailored to prevent or

remedy infringement. See Joy Techs., Inc. v. Flakt, Inc., 6 F.3d 770, 777 (Fed. Cir.

2009-1374                                    24
1993). Although we have discouraged judicial restraint of noninfringing activities, Johns

Hopkins Univ. v. CellPro, Inc., 152 F.3d 1342, 1367 (Fed. Cir. 1998), we have also held

that broad injunctions that preempt future design-arounds may be used in exceptional

cases where the district court reasonably concludes that such measures are necessary

to compel compliance with the court’s orders. See Additive Controls, 154 F.3d at 1356.

Where an infringer refuses to acknowledge a judicial finding of infringement and obey

an injunction barring future infringement, the district court has broad discretion in

enforcing its orders.

       Having presided over this case for many years, the district court was in a unique

position to evaluate the likelihood that EchoStar would continue to infringe TiVo’s

patent.   Id. (emphasizing that the “district court’s familiarity with the proceedings”

justified upholding an injunction requiring pre-approval of “any activities with respect to”

infringing devices); Spindelfabrik Suessen-Schurr Stahlecker & Grill v. Schubert &

Salzer, 903 F.2d 1568, 1577 (Fed. Cir. 1990) (explaining that repeated and blatant

violations of the district court’s earlier injunction fully justified broad provisions requiring

court approval before implementing design around efforts). Given EchoStar’s refusal to

disable the DVR functionality in its existing devices and the fact that its original attempts

to design around TiVo’s patent were wholly unsuccessful, the district court had ample

justification for its determination that court pre-approval of any new design-around effort

was necessary to prevent future infringing activity.        We see no reason to set this

determination aside.

                                       CONCLUSION

       We have considered the EchoStar’s remaining arguments and do not find them

2009-1374                                     25
persuasive. Accordingly, the judgment of the district court is

                                                   I.

       “Contempt . . . is not a sword for wounding a former infringer who has made a

good-faith effort to modify a previously adjudged or admitted infringing device to remain

in the marketplace. Rather, the modifying party generally deserves the opportunity to

litigate the infringement question at a new trial, ‘particularly if expert and other testimony

subject to cross-examination would be helpful or necessary.’”           Arbek Mfg. Inc., v.

Moazzam, 55 F.3d 1567, 1570 (Fed. Cir. 1995) (quoting KSM Fastening Sys., Inc. v.

H.A. Jones Co., 776 F.2d 1522, 1531 (Fed. Cir. 1985)).            Citing a broad injunctive

provision and a substantially-altered accused design, this court today punishes a good

faith design-around effort.
      A full examination of the disputed claim shows little similarity between the former

infringement proceedings and the issues now before this court. The accused structures

are different.   The theories of infringement are different.        The pertinent claim

constructions apply in ways that are different. The parties’ positions have flip-flopped.

The modified method operates in a significantly different way from the old. Indeed, the

only thing that is not different is the identity of the parties themselves.           These

differences deserve a trial, not a summary contempt proceeding.

                                            II.

      “Even if Echostar had achieved a non-infringing design around, this Court would

still find that Echostar is in contempt of this Court’s permanent injunction.” Those words

come directly from the district court’s contempt order. In other words, even assuming

the modified technology falls outside the asserted claims, Echostar would still be in

contempt. How can that be correct?

      Under its strained interpretation of its earlier injunction, the district court

effectively required Echostar to go into each of its customers’ homes and physically

remove each cable box containing any DVR functionality — infringing or not! The trial

court required this course of action even in the face of both parties’ recognition that a

satellite link could more easily remove or replace the “infringing” technology. In other

words, if Echostar would enter each home and replace each of its cable boxes with

identical cable boxes uploaded with the same software, it would escape contempt.

These absurdities spring from the “disablement provision:”

      Defendants are hereby FURTHER ORDERED to, within thirty (30) days of
      the issuance of this order, disable the DVR functionality (i.e., disable all
      storage to and playback from a hard disk drive of television data) in all but

2009-1374                                   2
       192,708 units of the Infringing Products that have been placed with an end
       user or subscriber. The DVR functionality, i.e., disable all storage to and
       playback from a hard disk drive of television data) [sic] shall not be
       enabled in any new placements of the Infringing Products.

       While this court manages to find a way to refashion the intent and purpose of the

disablement provision, no reasonable patent attorney would read it as this court does.

The district court’s injunction applied only to infringing products. The court did not refer

to any modified product or any other “DVR functionality” for that matter.            Yet, the

injunction today applies to any DVR functionality regardless of infringement.

       Neither Tivo nor this court cite to any case supporting such a broad injunction. In

fact, this court’s case law directs otherwise: “If a trial court is faced with an overly broad

injunction during a contempt proceeding, the court should interpret it according to the

rule of law quoted from KSM,” which prohibits only “infringement of the patent by the

devices adjudged to infringe and infringement by devices no more than colorably

different therefrom.” Int’l Rectifier Corp. v. IXYS Corp., 383 F.3d 1312, 1316 (Fed. Cir.

2004). This court only gives that rule lip service.

       The reason for this rule is clear: “[T]hose against whom an injunction is issued

should receive fair and precisely drawn notice of what the injunction actually prohibits.”

Granny Goose Foods, Inc. v. Bhd. of Teamsters, 415 U.S. 423, 444 (1974).                 This

premise has “led courts to construe injunctions narrowly where they failed to give

adequate notice that particular conduct was enjoined.” Abbott Labs. v. TorPharm, Inc.,

503 F.3d 1372, 1382 (Fed. Cir. 2007). Because no reasonable patent attorney would

have read the disablement provision to cover what is now enjoined, this court’s decision

sounds rather hollow in referring to Echostar’s failure to appeal. In the end, Echostar

2009-1374                                     3
should rely on the most reasonable interpretation of the disablement provision and

avoid unnecessary appeals. If the district court wished to enjoin the broad conduct it

now claims it did, it should have done so with a few simple words and given clear notice

of its expectations. Instead, it provides an artificial, after-the-fact justification for its

contempt finding.

       In the proceedings leading up to the injunction, Tivo used broad language to

request an injunction that it characterized as “narrow.” In defending the very language

ultimately adopted by the district court, Tivo stated that it was only seeking to enjoin

“infringement of the patent by the devices adjudged to infringe and infringement by

devices no more than colorably different therefrom” — “nothing more, nothing less.”

The record belies these representations.

       For starters, this court and Tivo draw a dichotomy between hardware and

software claims. At the time of the injunction, neither party nor the district court offered

such a distinction. To the contrary, the only distinction tendered by Tivo was between

“new placements” and “existing placements.” New placements referred to cable boxes

sitting on the shelves of retailers and distributors awaiting distribution to customers.

Existing placements referred to cable boxes already installed in customers’ homes. As

to the former category, Tivo requested that Echostar “be ordered to recall and retrieve

from its distributors and retailers the infringing DVR products that have not yet entered

the stream of commerce or are in the possession of the distributors and retailers.” That

is, for this limited category of products, Tivo requested the exact proscription it now

seeks to apply to all of Echostar’s products. Echostar encouraged the trial court to

“enjoin only the provision of infringing DVR software to those boxes upon activation.”

2009-1374                                    4
The district court ultimately sided with Tivo:

       Defendants are hereby FURTHER ORDERED immediately to recall and
       retrieve from their distributors and retailers the Infringing Products that
       have not yet entered the stream of commerce or are still in the possession
       of Defendants’ distributors and retailers.

       The existing placements, however, were a different story. As to that category of

products, Tivo admitted that Echostar could avoid infringement and the scope of the

putative injunction by merely reprogramming and disabling the DVR functionality in

question. Tivo made the following admission:

       Echostar can reprogram and disable the infringing DVR functionality in all
       existing DVR units by updating their software via satellite transmission. . . .
       Echostar has used this method of updating software routinely.

These statements appear directly below the heading “Existing placements” in Tivo’s

brief supporting an injunction submitted after the jury returned a verdict of infringement

on both hardware and software claims. Yet surprisingly, this court now claims that

Echostar was on notice of the broad reach of its injunction. Again, Tivo expressly

acknowledged that the infringing technology could be removed and replaced via

satellite. Tivo now disingenuously contends that its intention during all stages of the

proceedings was to force Echostar to physically remove all of its products containing the

infringing software.   Given Tivo’s clear bait-and-switch ploy, this court should have

recognized and forbid this game.

                                             III.

       Turning to the “infringement provision,” contempt proceedings are not the

appropriate forum to resolve the infringement issues on the “parses video and audio

data” limitation. Echostar’s modified design seems far “more than colorably different”

2009-1374                                        5
such that “substantial open issues with respect to infringement” remain. KSM, 776 F.2d

at 1530. In the original trial, Tivo identified Echostar’s “video frame start-code detection”

as infringing the limitation. That “start code” technology parses the digital video and

audio data before storing to memory so that the user can later conveniently reference

the individual frames when fast forwarding or rewinding through the data. According to

Tivo’s expert, the technology was necessary to produce a viable DVR.

       In its redesign efforts, Echostar eliminated its video frame start-code detection in

its entirety. Rather than parsing through all the video and audio data before storing onto

the system, the modified design, upon request from the user, statistically estimates

where a given frame might appear long after storage of the video and audio data. This

change was a critical component of a vast redesign effort by fifteen engineers working

full time for over 800 total hours.     Before proceeding, Echostar got two separate

approvals of this change from an independent law firm.

       Because of the substantial change to the design, Tivo abandons its infringement

theory premised on the start-code feature. Instead, Tivo focuses on an entirely different

structure in the modified device — the PID filter. The PID filter had been part of the

prior design but was never accused of infringement. Every channel broadcasted over

Echostar’s system carries a particular set of numbers known as the PID number.

Broadcast data breaks into two discrete components: header information and payload.

The header information contains the PID number. The payload contains the actual

video and audio data for the particular channel. Before passing through the PID filter,

the payload information is scrambled to avoid piracy. When a user turns the cable box

to a particular channel, the PID filter receives a message to pass the payload

2009-1374                                    6
information under that number to the user.

       The problem with Tivo’s new theory is simple: it had previously disclaimed the

PID filter as an infringing structure. Actually Tivo deliberately disclaimed it to avoid prior

art during the infringement trial. When asked directly by Tivo’s counsel about the PID

filter, Tivo’s expert admitted:

       And so inside the receiver card, the input section, yes, there is a little bit of
       what you might call separation in order to perform this translation, a little
       bit of what you might call even a type of parsing in order to pick out the
       correct packets and turn them and convert them into the MPEG-I.

       But just because these are words you use to describe this conversion
       process, you shouldn't confuse that with the claim terms. And when you're
       done with the input section, it's afterwards that comes the part of the claim
       that talks about the media switch that parses and separates.

For its part, Echostar argued that the PID filter did “parse video and audio data.” Tivo’s

arguments won at trial. Now the parties have directly switched positions. Tivo finds

infringement in the PID filter; Echostar finds no application of the claimed elements.

       A “modifying party generally deserves the opportunity to litigate the infringement

question at a new trial, ‘particularly if expert and other testimony subject to cross-

examination would be helpful or necessary.’” Arbek, 55 F.3d at 1570 (quoting KSM,

776 F.2d at 1530).      At the contempt proceedings, both parties proffered conflicting

expert testimony. Echostar’s expert highlighted that the PID filter did not even look to

the “video and audio” data because its role was restricted to passing only header

information. Indeed, at the point and time when the PID entered the broadcast chain,

the payload — i.e., the audio and video data — was necessarily scrambled for security.

In other words, the PID filter could not reference the audio and video data even if it

2009-1374                                     7
wanted to. And, of course, Tivo had previously renounced the PID filter as an infringing

structure.

       This record cannot support this contempt conclusion. The very structure which

provided the basis for Tivo’s infringement theory was eliminated by Echostar in its

modified design. This redesign, at a minimum, shows Echostar’s substantial good faith

efforts to comply. As noted, the new accused structure is and has always been a part of

Echostar’s design. Moreover, it has not changed its function in the slightest.

       Still, ignoring these problems, Tivo’s expert in the contempt proceedings relied

on the district court’s substitution of “analyzes” for the term “parses.” Tivo also stressed

that Echostar engineers used the term “parsing” in conjunction with the PID filter. Loose

language, particularly in reference to features ruled out as infringing technology earlier,

should not provide the basis for contempt. Rather, “[i]n litigated cases, the injunction

must be interpreted in light of the rulings of the court on the scope of the claims. The

patent owner may not, in contempt proceedings, seek to broaden the scope of the

claims which were adjudicated and, thereby, catch the modified device.” KSM, 776

F.2d at 1529; see also Cal. Artificial Stone Paving Co. v. Molitor, 113 U.S. 609, 618

(1885) (“Process of contempt is a severe remedy, and should not be resorted to where

there is fair ground of doubt as to the wrongfulness of the defendant’s conduct.”)

(emphasis added).

       As with the disablement provision, this court again relies on a distinction between

hardware and software claims to vitiate Tivo’s previous disclaimer of the PID filter. To

my eyes, this distinction deserves no credibility on this record. Tivo only presented one

theory of infringement to the jury.     That theory did not depend on any distinction

2009-1374                                    8
between hardware or software claims. To the contrary, Tivo’s theory spoke to all terms

across all asserted claims. Tivo’s expert admitted during the contempt proceedings:

       Q. Now back before the original trial, Dr. Storer, your opinion was that
       parsing meant the same thing in claim 1 and claim 31 and 61, right?

       A. I took parsing to be analyze as the court construction, and took it to
       mean the same thing, absolutely.

       Q. In all the claims?

       A. In all the claims.

Tivo simply provided no evidence for a reasonable jury to make any infringement finding

limited to either the hardware or software claims.          Nor were Echostar’s statements

about the PID filter limited to either software or hardware claims. Both types of claims

stood and fell together.

       At trial, the jury returned a verdict of infringement based on the record. That

record is entirely different from the theories, evidence, and positions in the contempt

proceeding.    Tivo should not be able to bootstrap its new, previously abandoned

infringement theory to that verdict. If Tivo believes that Echostar’s new design still

infringes its patent, it should file a new infringement suit, not attempt to short circuit a full

proceeding. In its current form, this decision discourages good faith efforts to design

around an infringement verdict.
