“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

“We agree with Patent Owner that claim 15 requires modifying the first instruction set before determining the modified first instruction set based on an at least partial match between the new digital picture and the first digital picture. Claim 15 recites “modifying: the first one or more instruction sets” and “determining the modified the first one or more instruction sets . . . based on the at least partial match between the new one or more digital pictures and the first one or more digital pictures.” Ex. 1001, 162:65–163:15 (emphasis added). The phrase “the modified . . . instruction sets” in the determining limitation indicates an order because it refers back to the instruction sets modified in the modifying limitation. Id. Further, the phrase “based on the at least partial match” indicates that a partial match between the new picture and the first picture returns the modified first instruction set. Id. In order for a partial match to return the modified first instruction set, it is logical that the first instruction set previously was modified and correlated to the first picture. Id. Thus, claim 15 indicates that the modifying limitation is performed before the determining limitation. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369 (Fed.

“In considering Patent Owner’s explanation, and upon further reflection, we agree with Patent Owner’s reading of the pertinent sentence. In that regard, consistent with the remainder of the Specification of the ’008 patent, it follows that the noted sentence does not alter the contours of “acquired” data to also encompass “passive” data where that premise is entirely absent from other portions of the Specification. Rather, as Patent Owner explains, the sentence is consistent with the understanding that it is “active data” that is connected to the word “acquired” and “passive data” that is connected to the word “available.” See, e.g., id. Patent Owner’s explanation alleviates the ambiguity that was postulated in the Institution Decision. We have considered Petitioner’s views to the contrary (see, e.g., Pet. Reply 21–25) but find them unavailing. In particular, Petitioner does not reconcile its position that, although acknowledging that “acquired data” is defined in the ’008 patent, the term “acquiring” is not so defined and should be regarded as an “individual word” whose meaning is somehow entirely unconnected to “acquired.” See, e.g., Pet. Reply 21. We note, as we did in the Institution Decision, that the ’008 patent states that “acquired data” and “its equivalents and verb forms” is “a type of active data.” See Inst. Dec. 30 (citing Ex. 1001, 3:25–32). We are not persuaded by Petitioner’s view (see, identifiable as a verb form of “acquired.” See PO Sur-reply 8. We determine that, in the context of the ’008 patent, it clearly is. Having considered the competing views of Petitioner and Patent Owner, we conclude that Patent Owner’s construction of the term “acquiring interest data” is consistent with, and supported by, the Specification of the ’008 patent. In that regard, we conclude that, as is advanced by Patent Owner, “acquiring interest data” must encompass the retrieval of some active data.” slip op. at 16

“Here, we conclude that: (1) the parties’ recognized level of ordinary skill in the art (see Pet. 4; PO Resp. 2); (2) the knowledge of a skilled artisan as set forth by record evidence, including the teachings of Willner and Kitts; and (3) the nature of the problem addressed in both of those references, i.e., click fraud detection, all support a determination that a skilled artisan would have had adequate reasons to combine Willner and Kitts, and would have had a reasonable expectation in doing so. To that end, we find persuasive Petitioner’s arguments in the Petition as to the proposed reasoning to combine Willner and Kitts, and also credit Dr. Lopresti’s supporting testimony. See Pet. 28–29; Ex. 1003 ¶ 118. We are mindful of the contrasting testimony referenced by Patent Owner’s declarant, Dr. Russ. See, e.g., PO Resp. 38 (citing Ex. 2011 ¶¶ 107–110). Dr. Russ testifies that, in his view, there are “practical” and “technical” “considerations” in combining Willner and Kitts that a “POSA would have had to consider in determining whether a reasonable expectation of success exists, none of which are addressed or discussed in the Petition.” See Ex. 2011 ¶¶ 107–110. The example considerations listed by Dr. Russ are reproduced below: 1. How Kitts’ passive data could be collected and stored in conjunction with the mouse vector data already being collected by Willner; 2. How to collectively analyze fundamentally different types of data—Willner’s mouse vector data on one hand, and Kitts’ passive data on the other; 3. How to generate a useful confidence score that is more accurate than the scores already generated by Willner, again taking into consideration that passive data is a fundamentally different type of data than active data; assessment using the complex statistical model of Kitts; and 5.

“Patent Owner’s argument is inapposite, as it is premised on reading a limitation into the claims, namely that the information encoded in the RF signal must be translated in real time. Further, we agree with Petitioner, that even under such an erroneously narrow construction, Cunningham would meet the limitation.

Petitioner argues, and we are persuaded, that “Cunningham explains that the ‘most current cumulative reading’ is the current absolute ‘reading’ (i.e., information signal) from the sensor (Ex. 1004, 13:44–46) and that two cumulative readings can be used to ‘interpolate’ and ‘recover’ a missed reading (i.e., a signal from the sensor).” Reply 7 (citing Ex. 1004, 13:44–56; 31:6–27; Pet. 75; Ex. 1002 ¶¶115, 152; Ex. 1046 ¶32).

“limitations in claim 9 are similar to the limitation at issue in Williamson. Specifically, the “proficiency sensing module” and “mode control module” limitations are in a format consistent with traditional means-plus-function limitations. Ex. 1001, col. 10, ll. 40–53; see Williamson, 792 F.3d at 1350. Each limitation replaces the term “means” with the term “module,” and recites certain functions performed by the module. Ex. 1001, col. 10, ll. 40– 53; see Williamson, 792 F.3d at 1350. The word “module” by itself does not provide any indication of structure. See Williamson, 792 F.3d at 1350–51; PO Brief 3 (“Thus, the module, like most computing elements, are a combination of relatively generic computer hardware coupled with software.”). Further, neither party argues specifically or identifies evidence indicating that the prefixes “proficiency sensing” and “mode control” impart structure into the term “module.” See Pet. Brief 2; PO Brief 5–6; Williamson, 792 F.3d at 1350–51. Patent Owner argues that the claim language imparts structure by reciting the input and output of each module. PO Brief 5–6; Tr. 25:7–14. The functions recited in claim 9, however, only describe certain inputs and outputs at a very high level (e.g., receiving signals from a guitar and comparing the received signals to expected signals).

As a result, the functions recited in claim 9 for the “proficiency sensing module” and the “mode control module” do not connote sufficiently definite structure. See Williamson, 792 F.3d at 1351.
