                            _________________________

Before RADER and SCHALL, Circuit Judges, and ALSUP, District Judge. *

SCHALL, Circuit Judge.

                                       DECISION

      Andersen Corporation (“Andersen”) appeals from the final judgment of the United

States District Court for the District of Minnesota which dismissed Andersen’s suit
      *
             Honorable William Alsup, District Judge, United States District Court for
the Northern District of California, sitting by designation.
against Pella Corporation (“Pella”) and W.L. Gore & Associates, Inc. (“Gore”) (together

“Appellees”) for infringement of independent claims 22 and 76 and dependent claims

12, 23-29, 55, 59, and 65 of Andersen’s U.S. Patent No. 6,880,612 (the “’612 patent”).

The court entered judgment after determining on summary judgment that the asserted

claims of the ’612 patent were invalid by reason of obviousness. See Andersen Corp. v.

Pella Corp., 500 F. Supp. 2d 1192 (D. Minn. 2007). Andersen also appeals the district

court’s dismissal without prejudice of Gore’s unresolved counterclaim relating to

unasserted claims in the ’612 patent, arguing that the dismissal should have been with

prejudice.

      Because we conclude that there exist genuine issues of material fact as to

whether one of skill in the art would have looked to the prior art upon which the district

court based its grant of summary judgment of obviousness, we hold that the district

court erred in granting summary judgment of invalidity in favor of Pella and Gore. We

therefore vacate the judgment dismissing Andersen’s complaint and remand the case to

the district court for further proceedings.      We affirm, however, the district court’s

dismissal without prejudice of Gore’s counterclaim.

                                     DISCUSSION

                                            I.

      The ’612 patent claims a reduced visibility insect screen. Conventional insect

screens typically consist of thick wires or fibers woven in a grid pattern. Such screens

obstruct the view through the windows and doors in which they are installed. The

screen claimed in the ’612 patent comprises fine, thin wires woven tightly together. The

2007-1536                                   2
result is a screen more transparent than conventional insect screens. An exemplary

claim from the ’612 patent is independent claim 76:

      An insect screening material in a frame removably attached to a
      fenestration unit that permits ventilation therethrough and having reduced
      visibility, comprising a plurality of screen elements having a diameter of
      0.007 inch or less, the screen elements having a tensile strength greater
      than 5500 psi, wherein the screening has a transmittance of light of at
      least 0.75 and a reflectance of light of .04 or less.

’612 patent, col.19 l.3-9.

      The accused device, a reduced visibility insect screen made by Pella, is sold

under the name VividView®. Andersen sued Pella and its supplier Gore alleging that

the VividView® device infringes the ’612 patent. Gore and Pella asserted affirmative

defenses of invalidity and unenforceability, while Gore asserted a counterclaim that

each of the claims of the ’612 patent is invalid. During discovery, Andersen identified

the claims that Pella and Gore allegedly infringed as claims 12, 22-29, 55, 59, 65, and

76. Gore and Pella jointly moved for summary judgment, challenging the validity of the

asserted claims of the ’612 patent. For its part, Andersen moved for summary judgment

on the defenses of Gore and Pella and also on Gore’s counterclaim of invalidity. By a

September 28, 2008 order, the district court denied all motions for summary judgment.

      Just weeks before the scheduled date of trial, Gore and Pella moved to re-open

their motions for summary judgment in light of the United States Supreme Court’s

discussion of the obviousness standard in KSR International Co. v. Teleflex, Inc., 550

U.S. --, 127 S. Ct. 1727 (2007). In KSR, the Supreme Court reversed our reversal of

the district court’s grant of summary judgment of invalidity on the ground of obviousness

in favor of KSR. 127 S. Ct. at 1745-46. According to the Court, we applied too rigidly

the requirement that an obviousness challenge demonstrate a teaching, suggestion,

2007-1536                                  3
and motivation to combine known elements (the “TSM test”) and failed to give due

weight to the nature of the problem to be solved and common sense. Id. at 1741-43.

       Taking into consideration KSR, the district court granted Gore and Pella’s motion

to re-open the motions for summary judgment on the limited issue of obviousness, and

the court requested further briefing from the parties. In their briefs and at oral argument

before the district court, Gore and Pella asserted that the invention claimed in the ’612

patent was rendered obvious by an electromagnetic-shielding mesh manufactured by

TWP, Inc. (“TWP”) in combination with Japanese Patent No. 195646, disclosing a

method of coating a screen with light absorbable black color to reduce reflection. These

two references were the basis of an obviousness rejection of Andersen’s patent

application by the United States Patent and Trademark Office (“PTO”). Eventually,

however, the application issued as the ’612 patent after Andersen overcame the

rejection by amending its claims to include the limitation “in a fenestration unit that

permits ventilation there through.”

       Applying the test for obviousness under 35 U.S.C. § 103(a), the district court

began with an analysis of the primary obviousness factors delineated in Graham v.

Deere Co. of Kansas City, 383 U.S. 1, 17-18 (1966): (1) scope and content of the prior

art, (2) the differences between the prior art and claimed invention, and (3) the level of

ordinary skill in the art. Andersen, 500 F. Supp. 2d at 1195-97. Since the court found

that the defendants had made out a prima facie showing of obviousness under these

primary factors, it then weighed the secondary considerations of nonobviousness

discussed in Graham, 383 U.S. at 17-18, including commercial success, long felt but

unmet need, and failure of others. Andersen, 500 F. Supp. 2d at 1197-98. Under the

2007-1536                                   4
direction of KSR, the court rejected “a ‘rigid approach,’ in favor of an ‘expansive and

flexible approach’ using ‘common sense’ when assessing whether an invention would

have been obvious to a person of ordinary skill in the art.” Andersen, 500 F. Supp. 2d

at 1195 (quoting KSR, 127 S. Ct. at 1739, 1742-43).

        In due course, the district court granted Appellees’ motion for summary

judgment, holding the asserted claims of Andersen’s ’612 patent obvious and the patent

invalid as a matter of law. Id. at 1198. In its discussion of obviousness, the court

asked, “[W]ould an insect screen manufacturer of ordinary skill have found it obvious to

use the TWP screening material, decrease its reflectance value, bond it, and place it in

a window frame?,” to which it responded, “The answer, plain and simple is ‘Yes.’” Id. at

1195.    In arriving at this conclusion, the court found that the “heart of Andersen’s

claimed invention” was the TWP mesh, which had been available on the internet and in

use prior to submission of Andersen’s patent application, and that it was a “simple act of

common sense—rather than of invention—for an insect screen designer of ordinary skill

to look [to it].” Id. at 1195-96. The court then considered secondary factors, only to find

that they could not rebut the strong prima facie showing of obviousness. Id. at 1197.

        Andersen filed a Notice of Appeal within 30 days of the summary judgment

ruling. However, Gore’s pending declaratory judgment counterclaim of invalidity relating

to no-longer-asserted claims of the ’612 patent prevented the district court’s judgment

from being final. Gore therefore moved to dismiss its counterclaim without prejudice.

Andersen moved to dismiss its own appeal before the district court decided Gore’s

motion to dismiss. On November 25, 2007, this court denied Andersen’s motion to

dismiss its own appeal and stayed briefing until the district court addressed Gore’s

2007-1536                                   5
pending motion. On February 21, 2008, the district court granted Gore’s motion to

dismiss its counterclaim without prejudice, and the parties proceeded to brief their cases

on appeal to this court. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(1) (2006).

                                            II.

      We “review the grant of summary judgment de novo, drawing all reasonable

inferences in favor of the non-moving party.” Teleflex, Inc. v. Ficosa N. Am. Corp., 299

F.3d 1313, 1323 (Fed. Cir. 2002) (citing Anderson v. Liberty Lobby, Inc., 477 U.S. 242,

255 (1986)). Summary judgment is appropriate “where there is no genuine issue of

material fact and the movant is entitled to judgment as a matter of law.” SRI Int’l v.

Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1116 (Fed. Cir. 1985) (en banc).

      Andersen argues that the district court erred in granting summary judgment of

invalidity by reason of obviousness because it raised genuine issues of material fact

with respect to whether one of ordinary skill in the art (here, “someone who

manufactures insect screens with no understanding of optics and physics,” Andersen,

500 F. Supp. 2d at 1195) seeking to design an insect screen with reduced visibility

would have looked to the TWP mesh. Appellees respond that the district court correctly

granted summary judgment in their favor because it would have been obvious to an

ordinarily skilled artisan to select TWP mesh—a commercially available highly

transparent screening material—as a material appropriate for a reduced visibility insect

screen.

      We agree with Andersen that genuine issues of material fact exist as to whether

it would have been obvious to an insect screen designer of ordinary skill to use the TWP

mesh as screening material for a reduced visibility insect screen. We begin, as the

2007-1536                                   6
district court did, by looking at evidence relating to the primary obviousness factors. We

agree with the district court that Andersen failed to raise a genuine issue of material fact

as to two of the factors: the differences between the prior art and the claimed invention

and the level of skill in the art. We do not agree, however, with the district court’s

finding that no genuine issue of material fact exists as to the scope and content of the

prior art.

        Upon our review of the record in the light most favorable to Andersen, we find

support adequate to overcome summary judgment on the question of whether the TWP

mesh was outside the scope and content of the prior art. Andersen put forth evidence

in the record that, one, the TWP mesh was not part of the insect screen manufacturing

field, and, two, an insect screen manufacturer would have read the prior art to teach

away from using a mesh with the characteristics possessed by the TWP mesh. This

field-of-invention and teaching-away evidence, combined with the deference owed to

the PTO’s issuance of this patent after reviewing the same prior art references that form

the basis of this obviousness challenge, raises a genuine issue of material fact as to

whether an ordinarily skilled insect screen designer would have found the combination

of the TWP mesh with the other prior art references obvious.

        Andersen submitted the TWP website as evidence that the TWP mesh used by

Andersen was beyond the field of invention. The TWP website posted links to separate

webpages for “Technical Information” pertaining to, among other things, an “Insect

screen” and a “High Transparency” screen. The TWP mesh used by Andersen was

found, not under the “Insect Screen” link, but under the “High Transparency” screen link.

The “High Transparency” webpage described the use of these “optical grade” meshes

2007-1536                                    7
as electromagnetic shielding in shielded windows and cathode ray tubes (CRTs). In

contrast, the “Insect Screen” webpage noted the “wide range of industrial and

commercial applications” available for insect screening and did not include

electromagnetic-shielding meshes.

      The district court was not persuaded that the advertised use of the TWP mesh

removed it from the field of invention.    It correctly observed that the TWP mesh’s

“advertised use [as] electromagnetic shielding . . . does not mean it was not available

for other uses.” Andersen, 500 F. Supp. 2d at 1196. Indeed, as the district court noted,

KSR teaches that common sense might make alternative uses of familiar items obvious

and that design incentives and other market forces can prompt variations of a work.

See id. (citing KSR, 127 S. Ct. at 1740, 1742).    The court found that common sense

and the nature of the problem to be solved would have made it obvious to use the TWP

electromagnetic-shielding mesh as an insect screen. Id.

      While we agree that common sense and the nature of the problem to be solved

could lead an insect screen designer to a mesh primarily used for a purpose besides

insect screens, we find that in this case Andersen raised a genuine issue of fact as to

whether the electromagnetic-shielding mesh would have been part of the field of

invention searched by an insect screen designer and whether such an alternative use

would have been obvious. See Para-Ordnance Mfg., Inc. v. SGS Imps. Int’l, Inc., 73

F.3d 1085, 1088 (Fed. Cir. 2005) (“[W]hether [the prior art] teaches toward or away from

the claimed invention also is a determination of fact.”). The fact that TWP’s use for the

mesh was electromagnetic shielding and that TWP, a company that manufactures

insect screens, did not employ this particular mesh as an insect screen suggests that

2007-1536                                  8
common sense and the nature of the problem to be solved might not have made it

obvious to an insect screen designer to try using the mesh as an insect screen.

       Andersen also submitted into the record prior art references that taught away

from using the TWP mesh as an insect screen. Several prior art references in the

record teach that the TWP mesh possessed many characteristics that an ordinary

skilled insect screen designer would have viewed as undesirable for an insect screen.

Specifically, the record at least raises the question of whether the TWP mesh lacked the

durability, transparency, and price feasibility preferred by an insect screen manufacturer

designing a reduced visibility insect screen.

       Andersen submitted evidence that durability is a desirable characteristic of insect

screens because they experience wear and tear from exposure to daily weather

conditions and interactions with humans and pets. Appellant’s Br. at 36-37. In that

regard, the TWP website called the electromagnetic-shielding mesh used by Andersen

the “world’s most delicate metal fabric” and specified that it requires “great care in

handling.”   The Sims Patent, a prior art reference also before the PTO examiner,

teaches that fine mesh should only be removed from the glass panes if it will not be

subject to accidental damage and contact. U.S. Patent No. 5,012,041, col.3 l.51-56

(filed Jun. 22, 1989). According to Andersen, the delicacy of the TWP mesh, its need

for special care, and its vulnerability to damage upon contact could discourage an insect

screen designer from using it.

       Andersen also presented evidence that using TWP mesh in an insect screen

would not, relative to conventional screens, heighten its transparency—the main

objective of the invention. Appellant’s Br. at 38-39. Andersen cites the Sims Patent for

2007-1536                                       9
its teaching that fine mesh produces optical interference, not invisibility, due to the

“distracting effects if . . . the wire grid is too fine.” Id., col.1 l.48-53. Evidence that the

TWP mesh used by Andersen qualifies as a fine mesh that might be shiny according to

the Sims Patent comes from the TWP website, which describes the wire comprising the

mesh as “many times finer than a single strand of human hair.”              This evidence is

somewhat contradicted by the fact that the TWP website also advertises this mesh as

“highly transparent,” but that description does not specify that the mesh was highly

transparent relative to insect screens. Given the evidence, a person of ordinary skill in

the insect screen art arguably would not think that increasing the number of wires in

combination with decreasing the diameters of the wires would yield an insect screen

with reduced visibility.

       As to the third characteristic, pricing, Andersen’s expert, Laurence Armstrong,

stated that the TWP mesh was “extraordinarily expensive in comparison with traditional

insect screen material, costing about $75.00 per square foot.” It is not unreasonable to

suggest that a significant difference in cost could discourage an insect screen designer

from using the more expensive mesh.

       The district court, however, was not persuaded that this teaching-away evidence

presented a genuine issue of material fact. The court acknowledged that the Supreme

Court in KSR approvingly cited United States v. Adams, 383 U.S. 39, 51-52 (1966), for

the “principle that when the prior art teaches away from combining certain known

elements, discovery of a successful means of combining them is more likely to be

nonobvious.” 127 S. Ct. at 1739-40. The district court, however, found Andersen’s

evidence of teaching away “disingenuous” in the face of the TWP website’s reference to

2007-1536                                     10
the screen as “highly transparent” and capable of use in “shielded windows.” Andersen,

500 F. Supp. 2d at 1196. In essence, the district court found that the teaching toward

evidence outweighed the teaching-away evidence in the record.

      We disagree with the district court in its evaluation of the teaching-away

evidence. On the whole, we think, the record creates a genuine issue of material fact

as to whether the durability, transparency, and pricing of the TWP mesh would have

discouraged an ordinarily skilled artisan from incorporating the mesh into an insect

screen. Recognizing that the Supreme Court in KSR cautioned us to not be too rigid in

applying the TSM test, we may still consider evidence of teachings to combine (and,

presumably, not to combine) because, according to the Supreme Court, they “capture[ ]

a helpful insight” into the obviousness inquiry. 127 S. Ct. at 1741. Unlike in KSR where

the Supreme Court concluded that “Teleflex ha[d] not shown anything in the prior art

that taught away from the [combination of prior art references],” Andersen has raised a

genuine issue of material fact as to whether the prior art taught away from using TWP

mesh as an insect screen. Id. at 1745.

      We also note that, in ruling on summary judgment, the district court was required

to view the evidence with an eye towards the burden on Gore and Pella to overcome

the deference due to the PTO. As “[t]he Supreme Court stated in Anderson, . . . ‘in

ruling on a motion for summary judgment, the judge must view the evidence presented

through the prism of the substantive evidentiary burden.’” Enzo Biochem, Inc. v. Gen-

Probe Inc., 424 F.3d 1276, 1284 (Fed. Cir. 2005) (quoting Anderson, 477 U.S. at 254).

As we have explained, the PTO examiner’s issuance of the patent is entitled to

deference:

2007-1536                                 11
       When no prior art other than that which was considered by the PTO
       examiner is relied on by the attacker, he has the added burden of
       overcoming the deference that is due to a qualified government agency
       presumed to have properly done its job, which includes one or more
       examiners who are assumed to have some expertise in interpreting the
       references and to be familiar from their work with the level of skill in the art
       and whose duty it is to issue only valid patents.

PowerOasis, Inc. v. T-Mobile USA, Inc., 522 F.3d 1299, 1304 (Fed. Cir. 2008) (quoting

Am. Hoist & Derrick Co. v. Sowa & Sons, Inc., 725 F.2d 1350, 1359 (Fed. Cir. 1984)).

       In this case, the TWP mesh is one of many references which Andersen

submitted to the PTO during prosecution. Indeed, the prosecution history makes clear

that the PTO examiner initially denied claims of the patent application as anticipated by

the commercially available TWP mesh and obvious in light of the TWP mesh combined

with Japanese Patent No. 195646 describing darkening a framed screen door.

Andersen overcame those rejections, however, and the PTO provided the following

reason for allowance: “The prior art does not disclose the screen material which has

the structure recited which is used as an insect screen . . . .” Unlike in KSR where the

PTO did not consider the prior art reference that ultimately rendered the patent obvious,

127 S. Ct. at 1729, the PTO examiner in this case considered whether the TWP mesh in

combination with other references rendered obvious the application that issued as the

’612 patent. In evaluating Gore and Pella’s joint motion for summary judgment of patent

invalidity on the basis of obviousness, the district court needed to consider the

additional burden born by Gore and Pella of overcoming the deference owed to the

PTO.

       Since we find that the record creates a genuine issue of material fact as to

whether the ’612 patent was obvious under the primary obviousness factors, we need

2007-1536                                    12
not examine the secondary obviousness factors in any depth. That aside, we note that

Andersen submitted evidence of long-felt need, the failure of others, unexpected results,

copying by Gore and Pella, and praise by others.              The record includes patent

applications by Gore explicitly discussing the long-felt need in the industry for an

invisible insect screen. That long-felt need was further illustrated by the fact that, at the

time of initial summary judgment motions, Gore had submitted several patent

applications in the United States on “Insect Screen with Improved Optical Properties.”

The record also reflects failure of others in that, for decades, Pella and others tried to

minimize visibility of insect screens by alternative methods, but failed.            As for

unexpected results, in its own patent application, Gore acknowledged the “surprising

visual effects of the invention” and unexpected results of the narrowly woven mesh.

Andersen also presented evidence of praise by others, including by Pella and Gore.

The district court noted that the other secondary factor, commercial success, favored

Gore and Pella.     See Andersen, 500 F. Supp. 2d at 1197.             Even so, Andersen

presented evidence suggesting that the majority of secondary considerations favored

dislodging an obviousness determination based on the primary obviousness factors.

        Review of the record in the light most favorable to Andersen reveals that

Andersen provided sufficient evidence of nonobviousness to overcome summary

judgment.

                                                  III.

       Andersen also argues that the district court abused its discretion when it

dismissed Gore’s unresolved counterclaim without prejudice under Rule 41(a) of the

Federal Rules of Civil Procedures and that the error was not harmless. Rule 41(a)(2)

2007-1536                                    13
provides that after an answer or motion for summary judgment has been filed, “an

action may be dismissed at the plaintiff’s request only by court order, on terms that the

court considers proper.” Fed. R. Civ. P. 41(a)(2). Andersen contends that Gore failed

to take any steps to prosecute its counterclaim, to explain its desire to dismiss its

counterclaim, and to provide an excuse for waiting to file its motion to dismiss until after

the district court granted summary judgment. Appellant’s Br. at 58-60. Andersen’s

alleged prejudice is that Gore avoided an adverse determination on the merits and

essentially received a “do-over.” Appellant’s Br. at 59.

       Because dismissal with or without prejudice is a question of procedure, we apply

the law of the regional circuit. See Intel Corp. & Dell Inc. v. Commonwealth Scientific &

Indus. Research Org., 455 F.3d 1364, 1369 (Fed. Cir. 2006). This case arises out of

the Eighth Circuit, and the Eighth Circuit reviews a district court’s dismissal without

prejudice under Rule 41(a)(2) for abuse of discretion. Paulucci v. City of Duluth, 826

F.2d 780, 782-83 (8th Cir. 1987). To determine whether to dismiss with or without

prejudice, the district court must consider the appropriate factors, including “whether the

party has presented a proper explanation for its desire to dismiss; whether a dismissal

would result in a waste of judicial time and effort; whether a dismissal will prejudice the

defendants; and whether a dismissal is sought merely to escape an adverse decision or

to seek a more favorable forum.” Highway Equip. Co. v. FECO, Ltd., 469 F.3d 1027,

1034 Fed. Cir. 2006) (applying Eighth Circuit law).

       We see no abuse of discretion in the district court’s dismissal without prejudice.

The court considered the briefs and memoranda submitted by the parties and found that

dismissal without prejudice was proper. Upon applying the Highway Equipment factors

2007-1536                                   14
to the record in this case, we find that the court properly exercised its discretion in

finding that those factors favored dismissal without prejudice.       In the briefs and

memorandum, Gore explained that after entry of summary judgment in favor of

Appellees on the invalidity of the asserted claims of the ’612 patent, it no longer needed

the counterclaim as to the unasserted claims. A dismissal of a declaratory judgment

counterclaim as to unasserted claims conserves judicial resources. While the motion

was presented relatively late in the proceeding (that is, once the district court granted

judgment of invalidity on the asserted claims), Gore explained that Andersen continued

to narrow the claims throughout the proceedings, and that once the counterclaim

obstructed a timely resolution of the case through immediate appeal, it entered its

motion. Most importantly, Andersen presented no evidence of prejudice besides a fear

of a second action on the unasserted claims, and “the mere prospect of a second law

suit” does not constitute sufficient legal prejudice to defeat a motion to dismiss without

prejudice. New York, C. & St. L. R. Co. v. Vardaman, 181 F.2d 769, 770 (8th Cir. 1950)

(quoting Cone v. W. Va. Pulp & Paper Co., 330 U.S. 212, 217 (1947)). The district court

did not abuse its discretion in finding that the Highway Equip. factors favored a

dismissal without prejudice.

      In sum, because we conclude that genuine issues of material fact remain as to

obviousness, we vacate the judgment entering summary judgment of invalidity in favor

of Appellees and dismissing Andersen’s complaint. The case is remanded to the district

court for further proceedings.   We affirm the court’s dismissal without prejudice of

Gore’s counterclaim.
