    “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

    “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

See e.g., Ex. 1001, 3:52–4:5, 7:18–20, Fig. 1). However, we find no disclosure that redefines “entity” or excludes dispatchers and individual users from the category of “entity.” Patent Owner’s best examples (e.g., Ex. 1001, 1:15–21, 3:59–62) are no more than non-limiting examples.

    “We agree with Petitioner. Although Petitioner bears the burden of correctly identifying the real parties-in-interest, “[w]e generally accept the petitioner’s identification of real parties-in-interest at the time of filing the petition.” See Zerto, Inc. v. EMC Corp., Case IPR2014-01254, at 6 (PTAB Mar. 3, 2015) (Paper 35) (citing Office Patent Trial Practice Guide, 77 Fed. Reg. 48,680, 48,695 (Aug. 14, 2012)). Here, Petitioner identifies in its Petition the real party-in-interest: “Pursuant to 37 C.F.R. § 42.8(b)(1), Unified Patents Inc. (‘Unified’ or ‘Petitioner’) certifies that Unified is the real party-in-interest.” Pet. 1. Such identification gives rise to a rebuttable presumption that Petitioner has complied with its obligation to identify all real parties-in-interest. See Zerto at 6–7. Patent Owner recognizes that “it [is] incumbent on the patent owner to come forward with some rebuttal evidence.” PO Resp. 52. 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. In view of the foregoing, we find that the circumstances here do not raise sufficient doubt about whether Petitioner has satisfied its obligation to name all real parties-in-interest. Therefore, we determine that the Petition should not be dismissed on this basis.” slip op. at 7

    “Rovira teaches each of the recited claim limitations, Petitioner must provide “some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006); see also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). In that regard, Petitioner directs us to Rovira’s teaching that “it is highly desirable to communicate program content information” because “having such information as music title, composer, artist and record label is vital” to music lovers. Pet. 16 (citing Ex. 1003, 1:30–32, 2:5–10); see also Ex. 1003, 1:32–35 (“Frustration of customers, and possible loss of revenue due to subscription cancellation can occur if a subscriber has no method of knowing the title, composer or artist of the particular selection of music.”). Petitioner argues it, thus, would have been obvious to modify Schotz’s system to incorporate a signal that includes both audio data and program data, as taught by Rovira. Pet. 17; see also, e.g., id. at 21 (“[O]ne would have been motivated to (1) modify Schotz’s transmitter 4 to transmit the digital audio signal of Rovira . . . and (2) modify Schotz’s receiver 6 to receive this digital audio signal.”); id. at 23 (“[T]his modification would result in Schotz’s user interface switch 18 selecting the digital audio data . . . within the digital audio signal [of Rovira].”); id. at 25 (“It would have been obvious to utilize the tuner 110 of Rovira in Schotz for [tuning] to frequencies that Schotz is receiving based on its use of Rovira’s digital audio signal. . . . Schotz is essentially doing this already, i.e., tuning to a frequency associated with audio data.”); id. at 27 (“[I]t would have been obvious to modify Schotz to utilize Rovira’s disclosed demodulator 125 to extract the selected digital audio data and the audio program information from the carrier wave, as taught by Rovira.”); id. at 28–29 (“It would have been obvious to modify Schotz to include the digital to analog converter 160 disclosed in Rovira. . . . The receiver 6 of Schotz would necessarily need a digital to analog converter when using the digital signals disclosed in Rovira so that the user can hear the selected music.”). We are persuaded by Petitioner’s reasoning, including specifically the quoted material in the preceding string citation to the Petition, for modifying Schotz’s system to include Rovira’s signal as well as various components for processing such a signal. See Kahn, 441 F.3d at 988. We note that “[a] person of ordinary skill is also a person of ordinary creativity, not an automaton,” and, in modifying Schotz’s system to include Rovira’s signal, would have made any necessary additional modifications such that Schotz’s system could process appropriately Rovira’s signal.
