      “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

      “IV. PATENT OWNER’S MOTION TO EXCLUDE Patent Owner seeks to exclude portions of Dr. Wieselthaler’s Declaration (Exhibit 1041), portions of Mr. Crosby’s Reply Declaration (Exhibit 1042), portions of the deposition transcript of Dr. Wieselthaler (Exhibit 2028), and the exhibits “upon which that testimony is based” (Exhibits 1015, 1038, 1044, 1046, 1049, and 1050). Mot. 1. According to Patent Owner, the Motion was made “to preserve objections previously made in the record.” Id. (citations omitted). Patent Owner did not timely move to strike any of the evidence at issue as being outside the scope of reply evidence. Patent Owner asserts that because an inter partes review must be based on prior art consisting of patents or printed publications (citing 35 U.S.C. § 311(b)), the testimony of Mr. Crosby and Dr. Wieselthaler concerning “various physical devices allegedly known” to a person of ordinary skill in the art is inadmissible, along with all of the exhibits (consisting of printed materials such a journal abstracts, press releases, and papers) related to those physical devices. Id. at 3–4; see also Mot. Reply 1–4 (arguing that “devices that Petitioner’s witnesses assert were in public use prior to the claimed inventions, are not prior art that can form the basis of an inter partes review”). According to Patent Owner, Dr. Wieselthaler was unable to “link two of these physical devices to the printed prior art asserted in this [inter partes review], but those attempts fell apart during his cross examination.” Id. at 4. Patent Owner further reasons that because the evidence “cannot be the basis” of an inter partes review, it “has probable,” “is irrelevant and not admissible,” “presents substantial danger of confusing the issues, causing undue delay, and wasting time in this trial,” and “are not ‘based on sufficient facts[,] the product of reliable principles and methods[, or] ‘a reliable application of the principles and methods to the facts of the case.’” Id. at 7 (citing Fed. R. Evid. 401–403, 702) (modification in original). With regard to Exhibits 1015, 1038, 1044, 1046, 1049, and 1050, Petitioner argues, and we agree, that Patent Owner identifies no plausible legal theory for their inadmissibility based on the contention that they discuss physical devices. See Mot. Resp. 3. We also agree with Petitioner that the exhibits are not “the basis for any ground” asserted in this proceeding, and may be properly relied upon by Dr. Wieselthaler and Mr. Crosby as support for their rebuttal testimony directed to Patent Owner’s arguments disputing Petitioner’s asserted motivation to combine the prior art relied upon in the instituted grounds.

      “‘electronics for power and control’”). According to Mr. Crosby, a person of ordinary skill in the art “would have understood based on the disclosure of this setup that these speed and motor parameters were monitored by a sensor providing feedback to the controller.” Ex. 1003 ¶ 725. Mr. Crosby identifies no support for this opinion, which we give little weight to. The mere fact that Bourque’s pump used software to control speed and motor parameters does not show that Bourque used “one or more sensors” to provide feedback signals to the external control unit. Indeed, Petitioner fails to identify any evidence that Bourque used any “sensor” to monitor “speed and motor parameters.” Mr. Crosby also states that “[e]ach of the ‘ultrasonic flow probe’ and the ‘solid-state catheter-type pressure transducer’ described in [Bourque] is a ‘sensor’ as recited in Claim 33 that provides feedback signals to the external control unit (e.g., ‘electronics for power and control’ and ‘data acquisition’).” Id. ¶¶ 581, 726. Mr. Crosby’s opinion is again unsupported by the evidence, because, as explained above, there is no teaching in Bourque that either the “ultrasonic flow probe” or the “pressure transducers” used in the “in vitro characterization” studies were part of the heart assist pump device. Based on our review and consideration of Petitioner’s arguments and evidence directed to claim 11, we find that Petitioner has not shown by a preponderance of the evidence that the asserted combination of Bourque and Wampler teaches or suggests each of the limitations of dependent claim 11. We reach the same conclusion for the same reasons with regard to claim 33.” slip op. at 48

      “consequence in determining the action.” Fed. R. Evid. 401. Fed. R. Evid. 702 serves “a ‘gatekeeping role,’ the objective of which is to ensure that expert testimony admitted into evidence is both reliable and relevant.” Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1360 (Fed. Cir. 2008). There is no question that the disputed testimony of Dr. Wieselthaler and Mr. Crosby is relevant to the asserted motivation to combine and reliable, only whether it becomes “not relevant” or “unreliable,” in light of limited scope upon which grounds of unpatentability may be based under 35 U.S.C. § 311(b), because the testimony is based on, or supported by, knowledge of physical devices and publications discussing physical devices. Patent Owner directs us to no support for the notion that an expert’s testimony in an inter partes review must be limited to only the prior art relied upon as grounds for unpatentability and may not take into account any knowledge of, or publications concerning, other “physical devices” that would have been known to a person of ordinary skill at the relevant time. See generally Mot.25 In sum, we find that Patent Owner has 25 Patent Owner improperly asserts for the first time in its Reply in support of the Motion that “Petitioner in this case is improperly relying on non-prior art evidence.” Mot. Reply 3. This argument was not made in the Motion, and Patent Owner fails to identify what “non-prior art evidence” it seeks to exclude. We recognize that Petitioner appears to raise the argument that “non-prior art evidence” may be relied upon by an expert, but Petitioner also fails to identify what evidence it is referring to and that argument was not responsive to any issue Patent Owner raised in the Motion. See Mot. Resp. 5. To the extent the Parties intend “non-prior art evidence” to refer to the testimony of Dr. Wieselthaler and Mr. Crosby, we view the issue as pertaining to the weight afforded that testimony, in light of the supporting evidence relied upon, rather than one of admissibility. for the exclusion of evidence in this proceeding and deny the Motion.” slip op. at 83

      “1. “magneto coupling” Claim 1 recites, in relevant part, “a second magnetic device . . . positioned to magnetically drive rotation of the magnetically driven rotor via a magneto coupling with the first magnetic device.” Ex. 1001, 5:34–37. Claim 11 recites, in relevant part, “the second magnetic device positioned axially closer to the first magnetic device than to the magnetically driven rotor so as to magnetically drive rotation of the magnetically driven rotor relative to the one or more walls via a magneto coupling with the first magnetic device.” Id. at 6:42–48. Petitioner argues that “magneto coupling” means “a transfer of torque from one rotating permanent magnetic component to another rotating permanent magnetic component via a magnetic field.” Pet. 8–9 (citing Ex. 1003 ¶¶ 68–87). According to Petitioner, this construction is consistent with the ’879 patent, which describes “a coupling between two rotating ‘bar magnets’—a drive wheel rotates one bar magnet which causes another bar magnet (connected to a rotor) to rotate.” Id. (citing Ex. 1003 ¶¶ 54–55 (analyzing Ex. 1001, 2:28–52, 4:44–64, Fig. 2)). Patent Owner argues that “magneto coupling” should be afforded “its plain and ordinary meaning, which would encompass a magnetic coupling through both rotating magnets and the use of a rotating magnetic Owner directs us to the testimony of Mr. Leschinsky, who explains that a person of ordinary skill in the art would have understood the ’879 patent to use “magneto coupling” to generally describe “a way to couple the rotor to a drive element while sealing the two from one another and avoiding use of a direct mechanical coupling.” Ex. 2015 ¶ 67. According to Patent Owner, “Petitioner provides no recognizable basis for limiting the plain meaning of magnetic coupling to one type of magnet and excluding another type of magnet.” PO Resp. 6–7 (citing Johnson Worldwide Associates, Inc., v. Zebco Corp., 175 F.3d 985, 989–992 (Fed. Cir. 1999)). We agree with Patent Owner that Petitioner does not provide a sufficient basis for limiting the plain meaning of “magneto coupling.” That the ’879 patent describes embodiments using bar magnets does not serve to require the use of permanent magnets for the recited “magneto coupling.” See Sisvel Int’l S.A. v. Sierra Wireless, Inc., 81 F.4th 1231, 1236 (Fed. Cir. 2023) (quoting Phillips, 415 F.3d at 1323 (“[A]lthough the specification often describes very specific embodiments of the invention, we have repeatedly warned against confining the claims to those embodiments.”)). Moreover, the claim language here is not so limited. 13 Patent Owner notes that Petitioner’s grounds of unpatentability based on Wampler and Bourque depend on the disclosure only of electromagnetic drives in each reference, implying that “Petitioner does not believe its own proposed narrower construction.” PO Resp. 6; see also Pet. 8 (Petitioner alleging that in the Parallel Proceeding Patent Owner “conflates ‘magneto coupling’ . . . with a stator drive using a stationary electromagnet, instead of a rotating magnet, to rotate the rotor magnet,” and asserting that as the basis for Petitioner’s reliance on Wampler and Bourque as teaching a “magneto coupling” in this proceeding (citing Ex. 1019, 7; Ex. 1003 ¶¶ 84–87)).” slip op. at 24

      “reasons discussed above. See supra Section III.D.3. Accordingly, because Petitioner’s contentions are premised on an unsupported claim construction that we reject, Petitioner fails to show how Wampler teaches or suggests “a magnetically driven rotor . . . axially adjacent to a first magnet device,” as required by claims 1 and 11, as well as by claims 2, 4, 5, 7, 8, 11, 12, 14– 16, and 18–20, which depend from either claim 1 or claim 11.
