      “(“POSITA”) “would be a Ph.D. student with a minimum of two years of experience in their faculty advisor’s laboratory” and would have an understanding of “electrospinning fibers, including for tissue engineering, tissue engineering techniques, and using/performing FFT analysis.” Pet. 20– 21 (citing Ex. 1003 § II.C7). Patent Owner does not dispute Petitioner’s proposal but specifies the set of disciplines within which the Ph.D. would have been earned, namely “bioengineering, chemical engineering, mechanical engineering, or a related engineering discipline.” PO Resp. 6. We adopt and apply Petitioner’s proposal as clarified by Patent Owner regarding the Ph.D. discipline.” slip op. at 7

      “At the outset, we agree with Patent Owner that the Specification purports to define “major peaks” in the following sentence: “The ‘major peaks’ herein refer to peaks higher than the average of the peaks in the result.” Ex. 1001, 13:28–29. We determine that this language satisfies at least two of the criteria set forth in Alnylam. Specifically, the sentence at “refers to” to explain what qualifies as major peaks. That is not the end of the inquiry, however, as we find there is still some ambiguity as to whether the patentee intended to define “major peaks” so as to require so-called “minor peaks” in the claimed invention. See Bell Atlantic, 262 F.3d at 1268 (“[T]he intrinsic evidence must ‘clearly set forth’ or ‘clearly redefine’ a claim term so as to put one reasonably skilled in the art on notice that the patentee intended to so redefine the claim term.”). Importantly, the Specification does not treat the existence of minor peaks as prerequisites for the existence of major peaks. Indeed, the Specification does not discuss “minor peaks” at all. See generally Ex. 1001. Likewise, none of the claims of the ’227 patent, whether challenged or unchallenged, recites “minor peaks” or any additional peaks beyond the disputed “major peaks.” Id. at 23:30–24:42. Nor does the Specification include an example of FFT analysis results in which the average of the peaks therein is calculated and those higher than the average are identified as major peaks.8” slip op. at 9

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundMixed

      “Petitioner has the better position. Huang2 teaches crosslinking and provides a reason for doing so (stability). In particular, Huang2 states: “To better mimic skin ECM, electrospun collagen fibers have been fabricated, however, the rapid degradation and poor mechanical properties determine that either crosslinking or combination with other materials is necessary to obtain a stable scaffold.” Ex. 1005, 1791 (emphasis added). It is true that, in describing work actually carried out, Huang2 states that blending with PCL was performed and does not mention crosslinking. See id. at 1792 (“Nanofibrous matrices of PCL and Collagen at a weight ratio of 3:1 were fabricated using electrospinning as previously described.”). However, the prior art – here, Huang2 – is not limited to that which it describes having created. See In re Mills, 470 F.2d 649, 651 (C.C.P.A. 1972) (“a reference is not limited to the disclosure of specific working examples”); see also In re Lemelson, 397 F.2d 1006, 1009 (CCPA 1968) (“The use of patents as references is not limited to what the patentees describe as their own inventions or to the problems with which they are concerned. They are part of the literature of the art, relevant for all they contain.”); In re Fritch, 972 F.2d 1260, 1264 (Fed. Cir. 1992) (“It is well settled that a prior art reference is relevant for all that it teaches to those of ordinary skill in the art.”). Huang2 teaches two stabilization methods when using collagen in scaffolds. Huang2 states that one or the other “is necessary to obtain a stable scaffold” (when using collagen), but it does not preclude or teach away from using Patent Owner-cited testimony of Dr. Mikos is not as definitive as Patent Owner suggests; Dr. Mikos’s testimony is that a person of ordinary skill in the art “typically would not have done both.” Ex. 2015 ¶64 (emphasis added). The bottom line is that Huang2 teaches the person of ordinary skill in the art two ways to stabilize scaffolds/matrices comprised of collagen, provides a reason for doing so (stability), and does not teach away from using both. We are persuaded that a “scaffold comprising crosslinked fibers comprising collagen” would have been obvious in view of the cited teachings of Huang2.” slip op. at 33

      “We are not persuaded by Appellant’s citations to either reference. As discussed above, Petitioner’s Ground 1 is premised on a person of ordinary skill in the art altering the native flat sheet structure of Huang2 by rolling it into a jelly-roll structure as taught by Kuo. See Pet. 41 (Beginning its claim 2 arguments with the following: “Claim 1 is obvious for the reasons expressed above in § X.A., supra, which are incorporated herein.”); see also Pet. Reply 17 (“[B]ased on the explicit teaching of Kuo, a POSA would have been motivated to take the electrospun flat scaffold made by the techniques of Huang2, seed it with the desired cells, and roll it to treat a tendon and ligament.” (emphasis added)). Indeed, the paragraphs of Kuo that Petitioner cites for disclosing “scaffold sheets,” explicitly describe rolling them into jelly-roll like structures. See Ex. 1018 ¶7 (stating that “the sheet is spirally contacting a scaffold sheet of fibrous material with a cell; and rolling the scaffold sheet in a jelly-roll like manner to form a spirally wound tissue construct”), ¶22 (describing a method comprising “forming a tissue construct by contacting a scaffold sheet of fibrous material with a cell; and rolling the scaffold sheet in a jelly-roll like manner to form a spirally wound tissue construct” and implanting it in a patient). Petitioner fails to argue that that “one or more elongated sheets” recited in claim 2 would encompass the rolled structure of its proposed modification. Nor does Petitioner articulate a claim construction argument that could support such an argument. Petitioner has failed to prove, by a preponderance of the evidence, that claim 2 would have been obvious over Huang2 and Kuo.” slip op. at 42

      “For purposes of this Decision, we adopt Petitioner’s definition of a POSITA. Petitioner’s witness (Mr. Cook) qualifies as a POSITA under this definition, and, therefore, is qualified to opine from the perspective of a POSITA on technical matters included within the areas of expertise prescribed by the definition. As indicated above, Petitioner’s definition of a POSITA does not require education in the field of optics and professional experience designing or analyzing optical apparatus, unlike Patent Owner’s definition. We are aware, however, that Patent Owner’s witness (Dr. Klopp) has more extensive experience with optical systems and methods than Petitioner’s witness (Mr. Cook). Compare Ex 1003 ¶¶ 8–14, Ex. 2005, 39:21–59:17, with Ex. 2003 ¶¶ 3–20, Ex. 2004, 1–2, Ex. 1015, 10:22–13:25. Although Mr. Cook possesses excellent credentials in the field of mechanical engineering, his experience in the design and analysis of optical systems and methods is sparse and insubstantial compared to that of Dr. Klopp. Id. Due to this difference in experience levels, in instances where the witnesses express differing views on factual issues related to optical systems and methods, we will accord more weight to Dr. Klopp’s testimony than to Mr. Cook’s.” slip op. at 8

      “through the light transmission portion and bottom output face 313 of light conductor 38, which teaches transmitting light in parallel with the longitudinal axis of the housing. Tseng does not disclose or teach that light is emitted through the side surface of annular protrusion 383 in a direction perpendicular to the longitudinal axis of the housing. Ex. 1004 ¶ 97. Petitioner’s assertions that this would be the case consist solely of conclusory statements, supported only by citations to Mr. Cook’s declaration. Mr. Cook, however, simply repeats Petitioner’s conclusory statements, without providing sound technical reasoning supported by objective evidence to explain and support his opinions. Ex. 2003 ¶¶ 101– 102, 105, 195–198, 202. We, therefore, accord little weight to Mr. Cook’s opinion on this particular matter because it “merely repeats, verbatim, the conclusory assertion for which it is offered to support,” and “does not cite to any additional supporting evidence or provide any technical reasoning [in] support.” Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). Furthermore, Mr. Cook’s opinion conflicts with that of Patent Owner’s witness, Dr. Klopp, who opines that a “POSITA would understand from Tseng’s third embodiment that light from the LED would bypass the annular protrusion 383 of outer cliff 381, while transmitting downwardly toward the output face 313.” Compare Ex. 1003 ¶¶ 174–175, 190–194, with Ex. 2003 ¶¶ 101–102, 105. As discussed above, Mr. Cook is qualified to opine from the perspective of a POSITA on technical matters included within the expertise of a person meeting Petitioner’s definition of a POSITA, which do not include optics and optical apparatus. We, therefore, credit Dr. Klopp’s opinion over that of Mr. Cook on this particular factual issue of how it is directly related to optical systems and methods about which Mr. Cook possesses limited relevant experience. See Ex. 1003 ¶¶ 6–15 (experience in communication systems and electronics); Ex. 2005, 55:16–58:19 (design experience with electronics that use indicator lights or fiber-optic communications; no professional experience with light pipes, diffusers, or plumbing fixtures). Dr. Klopp possesses substantial research and professional experience with optical methods, fiber optic light pipes, light guides, diffusers, prisms, and analysis of faucets, spray heads, and plumbing fixtures. See Ex. 2003 ¶¶ 6–10 Supra 8 (discussing weight accorded to conflicting witness testimony); see also Resp. 2–3 (arguing that “Petitioner’s expert, Mr. Cook, is a mechanical engineer with substantial professional experience in electronics for high-voltage power systems and communications, but he has limited experience with the claimed subject matter.”).” slip op. at 34

Under that standard, claim terms generally are given their plain and ordinary meaning as would have been understood by the ordinarily skilled artisan at the time of the invention when read in the context of the specification and prosecution history.

      “Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed. Cir. 2001) (noting that a description of the “present invention” as having a particular structure “is strong evidence that the claims should not be read to encompass the opposite structure”). Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan. Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed. Cir. 2011) (noting that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority . . . Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120”). Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28. In view of the foregoing, we are not persuaded that Patent Owner has demonstrated that the inventors of the priority applications were in possession of a magnesium cast composite that included less than 50 wt. % magnesium, or greater than 50 wt. % additives. As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence.

      “Deane thus teaches that adsorbent housing 602 and adsorbent bed columns 508a, 508b—the asserted separation cartridge—are part of an apparatus that rests on a support surface such as a table or floor. Based on Deane’s disclosure, we find persuasive Patent Owner’s contention, and Patent Owner’s witness’s opinion, that Deane’s housing 602/adsorbent bed columns 508a, 508b (separation cartridge) cannot be removed from the receptacle by movement of the separation cartridge vertically downward. Resp. 37–38; Ex. 2001 ¶¶ 118–131. Neither Petitioner nor Petitioner’s witness, Dr. Knaebel, points to any evidence of record showing that one of ordinary skill in the art would have understood that Deane’s housing 602/adsorbent bed columns 508a, 508b (separation cartridge) could be removed from manifold 512 (receptacle) by moving housing 602/adsorbent bed columns 508a, 508b (separation cartridge) downward when the apparatus is resting on a table or floor, as taught by Deane.

      “Giving effect to “by movement relative to the receptacle,” when interpreting this phrase in combination with “a separation cartridge selectively removable from a receptacle,” requires that the separation cartridge is removable from the receptacle by movement of the separation cartridge itself. Interpreting the removal direction limitation to encompass a stationary separation cartridge, as Petitioner proposes, would render “by movement relative to the receptacle” superfluous. Specifically, Petitioner’s interpretation of “relative movement” does not accord weight to the recitation “movement relative to the receptacle,” which requires something other than the receptacle—the separation cartridge—to move in order for movement to occur with reference to or in comparison with the receptacle. Petitioner’s interpretation of “relative movement” as permitting removal of the separation cartridge from the receptacle when the separation cartridge remains stationary, is inconsistent with the plain language of removal direction limitation as a whole. The plain language of the removal direction limitation indicates that the separation cartridge must be removable from the receptacle by movement of the separation cartridge in a specified (first) direction. Claim 1 defines the first direction as a direction opposite the (second) direction in which the inlet and outlet are oriented. The plain language of the removal direction limitation, therefore, requires that the separation cartridge is removable from a receptacle by movement of the separation cartridge in comparison to the receptacle in a direction opposite the direction in which the separation cartridge’s inlet and outlet are oriented.” slip op. at 15

In response to Petitioner’s identification of the real party-in-interest, Patent Owner contends that “this is not an instance where a petitioner’s certification in a petition can be taken at face value” because “evidence proffered by [Petitioner] in support of its position was withdrawn deliberately.” Id. at 53. We do not, however, require evidence beyond a petitioner’s identification of real parties-in-interest in the absence of rebuttal evidence that such identification is erroneous or incomplete. Petitioner’s withdrawal of Exhibit 1012 from the record does not constitute such rebuttal evidence.
