not be used to construe a claim unless the language remains ambiguous after consideration of all
the intrinsic evidence. Jd. at 866. In analyzing claim language, the words of the claim are given
their ordinary and customary meaning unless a special definition is chosen and plainly stated in
the patent. Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305 (Fed. Cir. 1999).

Under 35 U.S.C. § 112, 4 6, a patent applicant may choose to state claims in a
“means-plus-function” format, as opposed to claiming a specific structure in the patent claims.
Means-plus-function limitations “recite a specified function to be performed rather than the
structure, material, or acts for performing that function.” JMS Technology, Inc. v. Haas
Automation, 206 F.3d 1422, 1429-30 (Fed. Cir. 2000). Such limitations cover the particular
structure described in the specification and all equivalents thereof. Id. at 1430 (citing 35 U.S.C.
§ 112, 96). Our task in construing a means-plus-function limitation involves “Gdentifying the
claimed function and determining the corresponding structure or act disclosed in the
specification.” Jd. (citing Chiuminatta Concrete Concepts, Inc. v. Cardinal Industries, Inc., 145
F.3d 1303, 1308 (Fed. Cir. 1998)).

Discussion

As noted above, the parties’ disputes center around the following terms: “recorder
means;” “recording communications;” and “antennae means.”
1. “Recorder Means’?

The parties agree that the claims containing the term “recorder means” are means-

As an initial matter, the parties agree that the terms “recorder means” (as used in claim 1
of the ‘298 patent) and “recording means” (as used in claim 9 of the ‘078 patent) should be
interpreted in the same way. We will refer only to the term “recorder means”, but our discussion
shall apply equally to the term “recording means.”

194 F.3d 1250, 1257 (Fed. Cir. 1999). This presumption may be rebutted, however, if the claim
element does not recite a corresponding function or if the element recites sufficient structure or
material for performing that function. Neither exception applies here, and the claim element thus
invokes § 112, ] 6 treatment. Jd.

Our first task then is to identify the function that corresponds to the term
“antennae means.” We conclude that the function of the “antennae means” is “transmitting and
receiving mobile telephone communication signals,” as specifically stated in the claim element.
See U.S. Patent No. 6,058,298, col. 8, lines 12-13. Under § 112, ] 6, we next must identify the

structure in the specification which performs the recited function. Jd. (citing Rodime PLC v.

Seagate Tech., Inc., 174 F.3d 1294, 1302 (Fed. Cir. 1999).

Based on our review of the patent specification, we conclude that the
corresponding structure identified in the specification is a single, dual function antenna that
receives AM/FM signals and receives and transmits cellular telephone signals. Accordingly, the
Vosi patents will be construed to cover that type of antenna and any “equivalents thereof.” Again,
we find that it is premature to determine the equivalents of this corresponding structure, and we
reserve this analysis for a future date. That said, we do not believe that the location of the
antenna on the vehicle’s “exterior” is a necessary part of the structure. Section 112, { 6 “does not
permit incorporation of structure from the written description beyond that necessary to perform
the claimed function.” Micro Chemical, 194 F.3d at 1258. As the physical location of the
antenna does not appear to be necessary to the claimed function of “transmitting and receiving

mobile telephone communication signals,” we decline to construe the corresponding structure to

require a particular placement of the “antennae means.”

limitation, [the court] must take great care not to impermissibly limit the function by adopting a
function different from that explicitly recited in the claim.” Generation II Orthotics, Inc. v.
Medical Technology, Inc., 263 F.3d 1356, 1364-65 (Fed. Cir. 2001). Based on these principles,
we decline to read into the claim language a requirement that the recorder means have the
function of recording only voice communications.

In short, we find that the function of the “recorder means” is simply recording
communications — without any further limitation. As for the definition of “recording ,
communications,” we adopt the dictionary definition proposed by Vosi -- which both experts
agree constitutes an ordinary and plain meaning of the terms to one skilled in the art. See Kraft
Foods, Inc. v. International Trading Company, 203 F.3d 1362, 1366 (Fed. Cir. 2000) (a claim
term should be “given its ordinary meaning unless the specification or prosecution history
provide a special, different meaning or definition”). Accordingly, we define the term “recording
communications” as the “storing on some storage medium, for later retrieval, information

transmitted from one point to another.” We finally conclude, and the parties agree, that the

" terms “communications” (as used in claim 1 of the ‘298 patent) and “telecommunications” (as _,
oa

used in claim 3 of the ‘088 patent) have the same meaning.
After identifying the function of a claim limitation, we must next turn to
identifying the structure in the patent specification that corresponds to the claimed function. See,

e.g., Smiths Industries, 183 F.3d at 1357. We find, and the parties agree, that the structure

inventor. Vanguard Products Corporation v. Parker Hannifin Corporation, 234 F.3d 1370,

plus-function claims. As discussed above, our task is to determine the function of the “recorder
means,” and to identify its corresponding structure in the specification. See, e.g., IMS
Technology, 206 F.3d at 1430. (

Claim 1 of the ‘298 patent claims an audio/mobile telephone system comprising,
among other things, “a recorder means connected to said audio system and said mobile telephone
for recording communications passing through said mobile telephone.” U.S. Patent No.
6,059,298, col. 8, lines 14-16. Vosi argues that the function of the “recorder means” is
“Tecording communications;” it further defines “recording communications” as the “storing on
some storage medium, for later retrieval, the information transmitted through the telephone.”
Vosi’s definition is derived from various scientific dictionaries. See Defendants’ Claim
Construction Brief at 5-6.

Motorola argues that the function of the “recorder means” should be limited
exclusively to “recording voice communications.” To arrive at that conclusion, Motorola points
to a reference in the patent specification to the recording of “voice communications.” See U.S.
Patent No. 5,797,088, col. 6, lines 45-50. However, nothing in the claim itself limits the function
of the “recorder means” exclusively to voice communications, and accordingly Motorola’s
attempt to read in such a limitation is improper. Indeed, when construing claims, a court must
not “import [a] limitation ... from the written description into the claim” where the claim
language is clear on its face. Smiths Industries Medical Systems, Inc. v. Vital Signs, Inc., 183
F.3d 1347, 1357 (Fed. Cir. 1999); Comark Communications, Inc. v. Harris Corporation, 156

F.3d 1182, 1186 (Fed. Cir. 1998) (limitations from the specification are not to be read into the ~

claims). Further, “[w]hen construing the functional statement in a means-plus-function

2. Antennae Means

Although both parties assert that the meaning of the term “antenna” is in dispute,
we believe that the real dispute lies in the meaning of the term “antennae means,” as used in
claim 1 of the ‘298 patent and the ‘078 patent.* Indeed, the parties’ briefs reveal not a
disagreement with what constitutes an “antenna,” but rather whether the Vosi patents cover an
invention that makes use of more than one antenna, as opposed to a single, dual-function
antenna.

As an initial matter, we will adopt the definition of “antenna” from the McGraw-
Hill Dictionary of Scientific & Technical Terms, 5th Edition: “a device used for radiating or
receiving radio waves.” See Exhibit 5 to Defendants’ Claim Construction Brief. Defining this
term does not resolve the parties’ dispute regarding single versus multiple antennas, and so we
move to an analysis of the term “antennae means.”

a. The ‘298 Patent

Claim 1 of the ‘298 patent claims “an antennae means for transmitting and
receiving mobile telephone communication signals.” We conclude that the term “antennae
means” (like “recorder means”) is a means-plus-function limitation. Generally, if an applicant
uses the word “means” in a claim element, it is presumed to invoke means-plus-function

treatment under § 112,96. See, e.g., Micro Chemical, Inc. v. Great Plains Chemical Co., Inc.,

4Claim 1 of the ‘298 patent refers to “an antennae means.” It is our understanding that the
word “antennae” is a version of the plural form of “antenna.” See Webster’s Third New
International Dictionary, p. 91 (Unabr. Ed. 1993). However, the applicant’s use of the word “an”
before “antennae” suggests that the word “antennae” was intended to be singular. In any event,
Vosi does not argue that the use of the word “antennae” denotes the plural, so we see no reason
to attach any significant to the usage.

b. The ‘078 Patent

The ‘078 patent differs from the ‘298 patent in that Claim 1 of the ‘078 patent
refers to a “first antennae means” and a “second antennae means.” The claim relating to a “first
antennae means” appears to refer to the antenna that is part of the mobile telephone itself (and
that is used by the telephone when it is away from the owner’s vehicle); in any event, this term
does not appear to be in dispute. The parties’ dispute focuses instead on the term “second
antennae means,” which both parties seem to suggest should receive the same interpretation as
“antennae means” in the ‘298 patent. We conclude that the additional term “second” serves only
to distinguish the shared antennae means from the antenna physically located on the mobile
telephone. Accordingly, we interpret the term “second antennae means” the same way as the
term “antennae means,” and our above discussion applies equally to the ‘078 patent.
3. Tape Recorder

As a final matter, the parties also engage in some debate regarding the meaning of
the term “tape recorder” in the ‘088 patent. Unlike the continuation patents, which identify only
a “recording means” or “recorder means,” the ‘088 patent provides a specific structural limitation,
in the claim itself. Motorola encourages us to define “tape recorder” as an audiocassette that
records voice communications. While we do not believe that the claim language indicates that
the “tape recorder” can only record voice communications on a traditional audiocassette, we do
conclude that the “tape recorder” of the ‘088 patent is limited to a device that requires 2
electromagnetic tape for recording.

CONCLUSION

The disputed claim terms are construed as set forth in this Memorandum Opinion

-10-


identified in the specification for “recording communications” is a “tape recorder that records
incoming and outgoing voice communication from the cellular telephone.”

Section 112, ] 6 further provides that the scope of a means-plus-function claim
includes not only the identified structure (here, the tape player) but also any “equivalents
thereof.” 35 U.S.C. § 112, 6. An equivalent structure is one that “performs the claimed
function in substantially the same way to achieve substantially the same result as the
corresponding structure described in the specification.” Odetics, Inc. v. Storage Technology
Corp., 185 F.3d 1259, 1267 (Fed. Cir. 1999). The parties hotly contest what constitutes an
“equivalent” to the structure identified in the specification — the tape recorder. Vosi proposes

>
that “equivalents” include such things as audiocassette recorders, hard disc drives, floppy disk
drives, CD-ROMs, “static semiconductor memory,” “EEPROM,” and other items that Vosi fails
to explain fully. In contrast, Motorola essentially argues that none of Vosi’s examples constitute
“equivalents” save an audiocassette recorder.

This issue, however, is for another day. Our task here is to construe the claims, an
issue of law; the parties’ debate regarding equivalents to the tape recorder identified in the
specification concerns, at least in part, a question of fact. See IMS Technology, 206 F.3d “ee
(equivalence under Section 112, [6 is a question of fact); Odetics, 185 F.3d at 1268-69 (whether

accused device is a § 112 equivalent of the described structure is a question of fact). It would be

difficult, if not impossible, to identify all conceivable equivalents at this juncture — particularly

~ on the relatively slim record provided by the parties. These issues are thus more appropriately

addressed on summary judgment or at trial.


The ‘078 Patent
Claims 9 and 10 of the ‘078 patent describe:

9. The audio/mobile telephone system ... further comprising a recording means for
recording communications through said mobile telephone.

10. The audio/mobile telephone system of claim 9 wherein said recording means is
located in said audio system.

In their briefs, the parties debate numerous terms contained in the patents.
However, discussions at the claim construction hearing and the parties’ post-hearing briefs made
clear that the disputes center around the terms “recording means,” “recording communications,”
and “antennae means.” We thus focus our discussion on these terms.

Legal framework

“An infringement analysis entails two steps. The file step is determining the
meaning and scope of the patent claims asserted to be infringed. The second step is comparing
the properly construed claims to the device accused of infringing.” Kraft Foods, Inc. v.
International Trading Company, 203 F.3d 1362, 1366 (Fed. Cir. 2000) (quoting Markman v.
Westview Instruments, Inc., 52 F.3d 967, 976 (Fed. Cir. 1995)). At this point, we are concerned
only with the first step, claim construction, which is a question of law to be decided by the Court.
Markman, 52 F.3d at 977-79.

In interpreting a patent claim, we look first to the “intrinsic” evidence, namely the
language of the claims themselves, the patent specification, and the prosecution history. Jd. at
979. Ifthe claim language is clear on its face, consideration of other intrinsic evidence is
restricted to determining whether it reflects a deviation from the claim language. Interactive Gift

Vosi patents is to “[iJntegrate[] a cellular telephone with a vehicular audio system to share
components, to eliminate duplication, to reduce costs and diminish the complexity of the overall
system.” U.S. Patent No. 5,797,088, col. 2, lines 11-14. At issue here are claims 1-5 of the ‘298
patent; claims 9 and 10 of the ‘078 patent; and claim 3 of the ‘088 patent.
The ‘088 Patent

Claim 3 of the ‘088 patent describes a “vehicular audio/cellular telephone system”
which comprises (among other things) “a tape recorder being capable of recording
telecommunications received and transmitted through said cellular telephone.”
The ‘298 Patent

Claims 1-5 of the ‘298 patent describe:
1. An audio/mobile telephone system comprising:

sok

an antennae means for transmitting and receiving mobile telephone communication
signals; and

a recorder means connected to said audio system and said mobile telephone for recording
communications passing through said mobile telephone.

2. The audio/mobile telephone system of claim 1 wherein said mobile telephone is
detachable and capable of use at a location distant from said audio system.

3. The audio/mobile telephone system of claim 1 wherein said audio signals include
standard AM/FM radio signals.

4, The audio/mobile telephone system of claim 1 where in said audio signals include
memory stored on an audio compact disc (CD).

5. The audio/mobile telephone system of claim 1 wherein said audio system includes a

MEMORANDUM OPINION AND ORDER

MATTHEW F. KENNELLY, District Judge:

Plaintiff Motorola, Inc. sued Vosi Technologies and Ivano Stamegna for a
declaratory judgment that three patents issued to Stamegna and owned by Vosi are not infringed.
Vosi subsequently filed a counterclaim against Motorola for patent infringement. The Court held
aclaim construction hearing on October 5, 2001. This opinion explains the Court’s construction
of the disputed claims of the patents.

Background

Vosi is the owner of three patents, U.S. Patent Nos. 5,797,088; 6,058,298; and
6,085,078, which refer to a “vehicular audio system incorporating detachable cellular telephone.”
The ‘088 patent was filed on October 30, 1995 and issued on August 18, 1998. The two other

Vosi patents were filed as continuation applications.’ The defendants also have one pending

' All the Vosi patents have the same specification; only the claim language differs.
Accordingly, all references to the patent specifications will be to the ‘088 patent.
