“In support of Petitioner’s position, Dr. Adanur testifies that “Nishida discloses that the unfinished surface area 1.1 is part of the web 1 itself,” that Nishida discloses that the computer-controlled process can (using Nishida’s phrase) “put in” up to seven different textile fibers or yarns into the web of material in one operation, and that, “[t]hus, Nishida discloses simultaneously knitting its layouts 2 and tongue 40 (each a ‘textile element’) with the unfinished surface area 1.1 (a ‘surrounding textile structure’).” Ex. 1002 ¶ 216 (citing Ex. 1022, 2:12–20, 4:47–55, 5:45–49). For purposes of institution, we credit that testimony over the testimony of Dr. Pastore, because, on the current record, we regard Dr. Adanur’s testimony as more consistent with the evidence. This and the other related issues may be explored more fully during the trial.” slip op. at 23

“Petitioner contends that: A person of ordinary skill in the art (“POSITA”) in the field of the ’749 patent in March 2004 would have been someone with at least a few years of experience in knit materials and knitting methods and machines that can be used in making footwear, or a bachelor’s degree in textile-related sciences, engineering, or industrial product design, or equivalent academic or work experience, including in the footwear industry. EX1002, ¶68. Such a person of ordinary skill would have at least a general understanding of general construction processes and materials used in the manufacturing process of fabric-based articles. For individuals with a lower educational level, a person could still be of ordinary skill in the art provided that person’s working experience compensates for any such lower educational level, or vice versa. See id. Pet. 23–24. Patent Owner states that, “[f]or purposes of this Preliminary Response, Nike applies Skechers’ definition for a person of ordinary skill in the art.” Prelim. Resp. 14. Petitioner’s definition is consistent with the level of ordinary skill reflected in the prior art references of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (recognizing that the prior art itself may reflect an appropriate level of skill in the art). For purposes of this decision, we apply Petitioner’s definition of the person of ordinary skill in the art.” slip op. at 10

“We recognize that it may be necessary “to look to interrelated teachings of multiple patents . . . in order to determine whether there was an apparent reason to combine the known elements in the fashion claimed.” KSR Int’l, 550 U.S. at 418. Petitioner in these proceedings, however, directs us to no persuasive reason why an ordinary artisan would have turned to the heat-retaining battery module of Hallaj when working to implement a plurality of Sato’s cells in a pack to replace the capacitors in Fohr. Pet. 36–38 (nowhere addressing that critical point); Reply 13 (devoting four sentences to rebuttal of Patent Owner’s persuasive evidence that one would not have combined the disclosures of Hallaj, Fohr, and Sato in the manner claimed); see Ex. 1033, 15 (Examiner’s observation, in confirming the patentability of the challenged claims during reexamination, that Sato contains “no information as to how Sato’s cells would be implemented in a pack”). We view Petitioner’s unexplained leap from the single battery cell of Sato to the heat-retaining battery module of Hallaj as a classic example of impermissible hindsight reconstruction driven not by any teaching in the prior art, but by the claim requirement of a “plurality” of cells implemented in a battery pack. Pet. 36–38; Reply 13. Patent Owner, by contrast, comes forward with persuasive evidence, which we credit, showing that one of ordinary skill in the art would not have been led to arrange a plurality of Sato’s cells in the heat-retaining battery module of Hallaj because such a modified battery pack would have been unsuitable for use as a replacement for the capacitors in Fohr. Specifically, we credit the testimony of Dr. Blomgren, who cogently explains why a person of ordinary skill in the art would not have been led to the proposed modification.

“We are not persuaded by Dr. Riley’s testimony that Fohr effectively teaches that both lithium-based battery cells and capacitors can achieve the 20 Amp Limitation, on a theory that “it’s actually the tool that draws the power” and “the right lithium cell” would be “a drop in replacement for this application.” Ex. 2169, 121:12–16 (Dr. Riley’s deposition testimony); Resp. 17. Dr. Riley readily admitted an unfamiliarity with capacitors, and identified no suitable “drop in” ready lithium cells available at the time of the invention. Ex. 2169, 121:11–122:4 (“[I]f I had a cell that could do similar things, I’d certainly swap it in there.”). On that point, we find more credible Dr. Blomgren’s testimony that “there is no guarantee that a given pack of battery cells can provide the current that a tool tries to draw.” Resp. 17 (citing Ex. 2147 ¶ 60).” slip op. at 13

“B. Level of Ordinary Skill in the Art We hold that the prior art references asserted in the Petition are representative of the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (absence of specific findings on “level of skill in the art does not give rise to reversible error ‘where the prior art itself reflects an appropriate level and a need for testimony is not shown’” (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)). To the extent that a more specific definition is required, we hold that an ordinary artisan would include one holding a Bachelor’s Degree in Electrical Engineering with two or three years of experience in battery design. That definition comports with the very similar definitions advanced by the parties. In that regard, Petitioner asserts that an ordinary artisan would encompass a person holding a Bachelor’s Degree in Electrical Engineering with three years of experience in battery design. Pet. 8; Ex. 1007 ¶ 9. Patent Owner similarly asserts that an ordinary artisan would include a person holding a Bachelor’s Degree in Electrical Engineering with two years of battery design experience. Resp. 8; Ex. 2105 ¶ 24.” slip op. at 9

“In our Decisions to Institute, we construed the 20 Amp Limitation to require that “the battery cells, when configured together in a battery pack, are capable of producing reasonably close to 20 amps of discharge current or greater over the course of delivering their entire rated capacity.” Dec. 5. Neither party disputes that construction, which we adopt for the purposes of this Final Written Decision. To the extent that any other claim term requires express construction, we discuss the construction in our analysis below. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (only claim terms in controversy need be construed, and then only to the extent necessary to resolve the controversy).

“a patent reexamination proceeding. The substitute claims proposed in a motion to amend are not entered automatically and then subjected to examination. Rather, the proposed substitute claims will be added directly to the patent, without examination, if the patent owner’s motion to amend claims is granted. In a motion to amend, the patent owner is not rebutting a rejection in an office action, as though this proceeding were a patent examination or a reexamination. Instead, the patent owner, as the movant, bears the burden of establishing the patentability of the proposed substitute claims over the prior art of record and also other prior art known to Patent Owner. We deny the motion to amend because (1) Patent Owner has not met this burden and (2) Petitioner has shown that the substitute claims would have been rendered obvious over the combination of the teachings of Nishida and Schuessler I and II.” slip op. at 34

“The current situation does not require us to assess the merits of Petitioner’s motion to exclude. As discussed above, even without relying upon the aforementioned portions of the cross-examination testimony of Dr. Frederick, we have concluded that Patent Owner has demonstrated that the term “flat knit edges” of substitute claims 47-50 is supported by the disclosure of the ’289 Application. Accordingly, Petitioner’s motion to exclude evidence is dismissed as moot.” slip op. at 41

“In construing the term “flat knitting,” we apply the broadest reasonable interpretation of the words in their ordinary usage, as those words would be understood by one of ordinary skill in the art, taking into account any definitions supplied by the Specification. See In re Morris, 127 F.3d 1048, 1054 (Fed. Cir. 1997). The Specification of the ’011 Patent expressly describes flat knitting as a sub-type of weft knitting. Ex. 1002, col. 7, ll. 5-8. Ultimately, “[t]he construction that stays true to the claim language and most naturally aligns with the patent’s description of the invention will be . . . the correct construction.” Renishaw PLC v. Marposs Societa’ per Azioni, 158 F.3d 1243, 1250 (Fed. Cir. 1998). Further, Patent Owner presents evidence that a person of ordinary skill in the art would understand flat knitting to describe a sub-type of weft knitting. Paper 44, 1 (quoting a textile dictionary (Ex. 2011, 6) to state that “the trade uses the term flat knit fabric to refer to weft knit fabrics made on a flat machine, rather than warp-knit fabrics”); see also Ex 2017, 5; Ex. 2018, 6. Despite its argument, Petitioner identifies no portion of the Specification of the ’011 Patent that describes flat knitting with respect to warp knitting or any other type of knitting, beyond weft-knitting. See Paper 37, 2-3. In addition, before the filing date of the motion to amend, Dr. Frederick, Petitioner’s expert, testified that “[f]lat knitting would be another type of weft knitting that would involve an end result that was . . . on a curved 15 surface, but more or less flat.” Ex. 2009, 89, ll. 6-11. Therefore, we determine that the term “weft knitting” describes a type of knitting in which a continuous yarn is carried in crosswise rows, and we construe the term “flat knit” to recite a sub-type of weft knitting, in which the weft knit textile is produced as a sheet of more or less flat material.5” slip op. at 15

“Petitioner contends that Nishida and Schuessler I are in similar fields and address the same problem, namely the formation of two-dimensional textile elements having edges that are joined to form three-dimensional, wearable items. Paper 37, 11; cf. Ex. 1005, figs. 1 (two-dimensional layout 2) and 3 (three-dimensional, shoe upper 3); Ex. 1020, figs. 1 (two-dimensional helmet swatch) and 2 (three-dimensional helmet). Further, Schuessler II teaches that the two-dimensional helmet swatch of Figure 1 of Schuessler I may be knit to shape on a flat knitting machine. Paper 37, 11 (citing Ex. 1023 ¶ 15). Petitioner contends, therefore, that a person of ordinary skill in the art would have reason to combine the teachings of these three references to achieve the invention recited in substitute claim 47. Id. Patent Owner does not argue Petitioner’s assessment of the teachings of these references. Patent Owner also does not dispute that all of the limitations of the claims are taught in the prior art. Instead, Patent Owner argues that Petitioner’s contention that a person of ordinary skill in the art would combine Nishida’s teaching regarding the reduction of waste by placing layouts in adjoining positions and Schuessler I’s teaching regarding knitting textile elements to shape is illogical. Paper 44, 5. Specifically, Patent Owner argues that Petitioner’s reason for combining these teachings is somehow flawed because “after they are combined the elements of each reference serve the same purpose.” Id. As the U.S. Supreme Court explained, however, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious 38 unless its actual application is beyond his or her skill.” KSR Int’l Co. v. Teleflex Inc., 555 U.S. 398, 417 (2007). In this case, that the elements of the prior art references would “serve the same purpose” when combined is a factor in favor of an obviousness determination, and not a suggestion of nonobviousness, as urged by Patent Owner. Because we are persuaded that Petitioner has demonstrated that the teachings of Nishida and Schuessler I and II teach or suggest all of the limitations of substitute claim 47 and that a person of ordinary skill in the art would have had reason to combine the teachings of these references to achieve the recited article of footwear, we determine that Patent Owner fails to meet its burden of showing that it is entitled to the relief requested in its motion to amend. Because we group substitute claims 48-50 with claim 47 for purposes of assessing patentability, we also determine that Patent Owner fails to meet its burden of showing that it is entitled to the relief requested in its motion to amend with respect to substitute claims 48-50. Consequently, the portion of Patent Owner’s motion to amend requesting entry of substitute claims 47-50 also is denied for failing to demonstrate that the substitute claims are patentable over Nishida and Schuessler I and II.” slip op. at 38
