      “I agree with Patent Owner. Neither Kraft nor Wong uses the term “data feed” or characterizes its listing of Web pages (Kraft) or nodes (Wong) provided in response to a user-provided query as a “data feed.” See Ex. 1005, 5:8–12, 6:52–59, 16:52–59, 18:31–54, 18:61–19:23; Ex. 1007 ¶¶ 22, 28, 35. Petitioner points to a disclosure in the ’463 patent of a user requesting a personal information aggregator (PIA) to “receive a data feed.” Pet. 23 (citing Ex. 1001, 12:52–64). But Petitioner does not sufficiently explain how this disclosure provides support for broadly construing “browsing a data feed” to encompass a user entering criteria for a search (and not specifically requesting a “data feed”) and receiving a listing of Web pages or nodes in response. See Pet. 23, 58–59; Ex. 1003 ¶¶ 102, 201–202; Ex. 1005, 6:57–59 (describing users searching a data store for models that match “user-specified criteria”), 18:41–54 (describing a user submitting a query); Ex. 1007 ¶ 28 (describing “searching and selecting from keyword identifiers or other search terms”). Petitioner’s reliance on a separate disclosure in the ’463 patent of the PIA “searching . . . the network for information about the situation or event” also is not persuasive, because the ’463 patent does not describe that embodiment as involving a data feed or browsing a data feed.

      “Petitioner misstates the Decision’s reasoning. As is clear from the previous discussion, we determined that Petitioner’s articulated reasons for combining EP’536 with CN’180 lacked a rational underpinning, not because “EP’536 does not relate to ‘air bags,’” but because the means by which EP’536’s device inflates differs fundamentally from that of CN’180’s device.

      “EP’536 with CN’180 lacked a rational underpinning because EP’536’s inflation mechanism differs fundamentally from CN’180’s inflation mechanism. Dec. 17–18. As we stated, whereas CN’180’s fall-protection belt uses an airbag that requires an external source of pressurized air to inflate, EP’536’s garment does not need an external inflation device because “the gas generating agent 18 in each envelope automatically generates gas and inflates the envelopes in response to rising temperatures.” Id. at 18 (citing Ex. 1004 ¶ 15; Ex. 1005 ¶¶ 5, 19). This difference reflects the fundamentally different purposes of the two devices: CN’180’s device is designed to provide “fall protection” to, e.g., “elderly people,” (Ex. 1005 ¶ 1, 3), whereas EP’536’s device provides “adaptive thermal insulation” for, e.g., garments worn by fire fighters. Ex. 1004 ¶¶ 1–3, 250. Because of the different means by which EP’536’s and CN’180’s devices inflate and the different purposes for doing so, we were not persuaded that one of ordinary skill in the art would have combined the references as Petitioner proposed. Dec. 18. We further noted that the modification would not have improved the reusability of EP’536’s device “by having only one mechanism to recharge,” because EP’536’s “gas generating agent does not need any ‘mechanism to recharge.’” Dec. 18. Instead, we noted EP’536’s teaching that its gas generating agent “automatically recombines or condenses in response to a temperature decrease to return the envelopes, and therefore the garment, to its original thickness, at which point the gas generating agent is ready for subsequent reactivation.” Id. (citing Ex. 1004 ¶¶ 139–141). Finally, we determined that replacing EP’536’s envelopes with CN’180’s airbag “would have made EP’536’s invention unsuitable for its intended purpose: providing a protective garment with ‘adaptive thermal insulation.’” Dec. 19. We stated that “Petitioner does not suggest, and we have found nothing in the record to establish, that CN’180’s airbag would provide this feature.” Id. at 20.” slip op. at 3

      “rationales for combining EP’536 and CN’180. Reh’g Req. 6–7. First, Petitioner asserts that we “improperly rejected Petitioner’s ‘simple substitution’ evidence in view of [the Board’s] incorrect conclusion that EP’536 does not disclose an ‘external source of inflation [EP’536’s dosing aids].’” Id. at 6 (citing Dec. 18–19). This argument is unpersuasive at least because, as we discussed above, EP’536’s dosing aids do not constitute an external source of inflation. Petitioner further argues that we incorrectly evaluated its “obvious to try” rationale because, contrary to our analysis, Petitioner did in fact identify a problem to be solved by its “finite number of solutions”: “simplify[ing] the design and reduc[ing] the number of required inflation mechanisms.” Id. at 6–7. The Petition’s entire “obvious to try” discussion is as follows: [A] POSITA would have found it obvious to try a one-piece airbag 10 with strip-shaped inflation units 12 in the EP’536- CN’180 airbag system because it would have been a selection from a finite number of identified predictable solutions (i.e., using one chamber with connected individual inflation units 12 versus multiple individual envelopes 20). 5 Petitioner also argues that dosing aids are “needed in order to make the disclosed device reusable.” Reh’g Req. 5–6. This is incorrect, as EP’536 conveys that the reusability of the device is a result of the gas generating agent condensing or recombining when temperatures fall. Ex. 1004 ¶¶ 139– 141. Even if it were true, however, it is unclear how it would support Petitioner’s argument. Pet. 16. As is evident, Petitioner did not identify a design need, market pressure, or other problem that would have been addressed by its identified “solutions,” and therefore we were not persuaded by this rationale. Dec. 19. Petitioner’s attempt to cure this deficiency in its Rehearing Request is tardy. We cannot misapprehend or overlook an assertion that Petitioner fails to make in the Petition. It is also insufficient. Petitioner does not provide any evidence of a known design need or market pressure to “simplify [EP’536’s] design” or reduce the number of “required inflation mechanism” it uses.” slip op. at 7

      “combination deficient. Petitioner argues that Park’s walls are “likely to collapse under the suction force,” based not on Park, but on Baughan, which states that “discs” in Baughan are used to prevent the “flexible sleeve” of Baughan from collapsing. Pet. 89. (citing Ex. 1007, 3:46–48). Petitioner reasons that because Park uses silicone, a flexible material, Park’s walls must also collapse like Baughan. Id. (citing Ex. 1006 ¶¶ 32, 34). Petitioner, however, directs us to no disclosure in Park to suggest that the material used in Park or the arrangement of Park would collapse in the same manner as Baughan. Indeed, if Park’s mouthpiece collapses as Petitioner speculates, it would appear likely to render Park inoperable. See Ex. 2030 ¶ 205. Additionally, Petitioner recognizes that in Park “the sidewalls and the insertion part 111 would help resist this collapsing force,” and states that in Park it “is unclear whether the mouth prop 100 includes a spine or other rigid structure running through the middle of the mouth prop 100.” Pet. 89– 90. Thus, whether Park is susceptible to collapse is, at best, unknown. See Prelim. Resp. 48 (asserting that a person of ordinary skill would have known “that silicone can have varying degrees of hardness, tensile strength, and elasticity such that Park’s mouthpiece would not necessarily collapse under suction”) (citing Ex. 2030 ¶¶ 189–90; Ex. 2036; Ex. 2037). Even assuming, as Petitioner asserts, that “additional anti-collapsing structure would assist at the weakest areas of the tongue retractor” in Park, Petitioner offers insufficient reasoning for why a person of ordinary skill would have turned to Baughan and modified the structure taught by Baughan to instead conform to what is recited in claim 1. Petitioner’s suggestion that “common sense” would have led a person of ordinary skill in the art to modify the structures of Baughan to solve a problem with collapse in Park that Park does not suggest was a problem is likewise unpersuasive and insufficient. Pet. 93 (further asserting that “it was well known in the art how to make projections on a flat surface”). Petitioner’s reliance on Johnson as generically teaching that protrusions can be on flat surfaces does not supply a reason why a person of ordinary skill in the art would have made the proposed modifications outside of improper hindsight. See also Prelim. Resp. 58, 59 (arguing that the projections in Johnson are on a semicircular surface, not on a flat surface as Petitioner asserts) (citing Ex. 1008 Figs. 4, 5). Based on the evidence and arguments presented, we determine that Petitioner fails to show sufficiently for purposes of instituting inter partes review that the asserted combination of Park, Baughan, and Johnson, or in further combination with Zheng, teaches “protrusions protruding from an interior surface” of one wall of the mouthpiece “towards” an opposing wall of the mouthpiece, as required by claim 1, or that a person of ordinary skill in the art would have had reason to combine the asserted references in the manner alleged by Petitioner.” slip op. at 28

      “Petitioner also fails to provide sufficient rationale and a reasonable expectation of success in combining Krishnan and Lee to arrive at a quality assessment neural network configured to receive an image. See Pet. 34–37. For example, the Petition lacks an explanation of why a POSITA would have been motivated to modify Krishnan’s quality assessment neural network to be configured to receive an image, instead of extracted features, in view of Lee’s image-receiving category classifying neural network. Id. Without such further explanation, Petitioner’s challenge falls short. Petitioner’s argument that neural networks for image quality assessment were “well-known” is not persuasive—it does not address the particular scope of limitation 1i, which also requires that the neural network is configured to receive images. Pet. 35 (citing Ex. 1002 ¶¶ 47–51, 118; Exs. 1017, 1023, 1024, 1026). Petitioner’s argument that combining Krishnan and Lee “would merely amount to applying known work from the field . . . to yield predictable results” is not persuasive because the Petition ties this reasoning to modifying Krishnan with Lee’s view-category-specific assessment parameters, not modifying Krishnan’s quality assessment neural network to receive images instead of extracted features. Id. at 37 (citing Ex. 1002 ¶ 126). Lastly, we note Petitioner’s expert’s discussion regarding neural networks for image quality assessments.

Based on the current record, we determine that no claim term requires an explicit construction to decide whether Petitioner satisfies the “more likely than not” standard for instituting a post-grant review. As Petitioner recognizes, the ’149 patent defines many of the claim terms Petitioner discusses in the “Claim Interpretation” section of the Petition. See Pet. 14–16. For instance, the patent defines “antenna rectangle” as “the orthogonal projection of the antenna box along the normal to the face with largest area of the antenna box.” Ex. 1005, 14:21–24. Further, the patent defines “complexity factor F21” and “complexity factor F32” consistent with the independent claims.

See Pet. 60–69; Ex. 1007 ¶¶ 172–187. Hence, based on the current record, Petitioner does not establish sufficiently for purposes of institution that an ordinarily skilled artisan would have been motivated to combine Ciais-Quadband’s teachings with Dou’s teachings in the way Petitioner proposes.

      “generally known in the art, and that this is acknowledged by the ’853 patent. Pet. 40–41 (citing, e.g., Ex. 1001, 15:40–44). Petitioner asserts that Kouzani touts the benefits of fractal models and that it would have been obvious to use Kouzani’s fractal model as the object model in Zhou. Pet 44 (asserting that “[a] person of ordinary skill would have therefore been motivated to implement Kouzani’s techniques in Zhao’s system”); see also id. 42–45. (entire argument). Patent Owner argues that Kouzani’s fractals would not result in the claimed limitation. Prelim. Resp. 21–23. In particular, Patent Owner points out that Kouzani’s fractals use a block-based fractal system, which do not include “a representation of the object based on landmarks associated with the object” as required by claim 1. Id. at 21–22. Patent Owner’s argument is persuasive. Even if Kouzani teaches fractals, claim 1 is not broadly claiming any fractal, but rather one that is “based on landmarks” (e.g., eyes, nose, etc.). See Ex. 1001, 13:53–57. The block-based system of Kouzani is based on abstract, repeated patterns of pixels, without regard to what the pixels represent. See, e.g., Ex. 1006, 8 (describing a “search . . . through the domain pool to find a domain block whose contractive transformation best approximates the range block” and then storing all of the transformations that, together, “represent the compressed image of a person’s face”), Fig. 4 (showing example blocks). This is in contrast to looking for particular landmarks in the image. Thus, we find that Petitioner has not sufficiently established that Kouzani’s fractal is based on landmarks. In Petitioner’s ground, Petitioner asserts that Zhao already teaches the claimed landmarks (Pet. 39, citing Ex. 1003 ¶¶ 58, 65), but Petitioner’s ground replaces or modifies the object model of Zhao with the fractals of Kouzani, which are not based on landmarks. Petitioner does not explain how Zhao’s modified model, now using a block-based fractal system, would still have the landmarks of Zhao’s original model. Even if it were obvious to include fractals, we are persuaded that the fractals included by Kouzani are not based on landmarks. Alternatively, if Petitioner is asserting merely to use fractals in Zhao’s models, then Petitioner has not sufficiently accounted for the particular fractals claimed and explained persuasively how merely using fractals in Zhao would lead to the claimed subject matter, i.e., fractals based on landmarks. In either event, Petitioner has not sufficiently established that the proposed combination satisfies the “fractal includes a representation of the object based on landmarks” limitation of claim 1.” slip op. at 11

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for patent owner

      “Claim 1 explicitly recites “partially,” not “fully” or “completely.” On its face, “partially” appears to have its plain and ordinary meaning, i.e., not completely. The use of “partially” in the subject limitation shows or at least strongly suggests that the claimed invention contemplates at least some frequency gap to remain between the first channel and the second channel. In addition, as argued persuasively by Patent Owner, this interpretation is further supported by claim 1’s requirement of “transmitting data subcarriers occupying the first channel, the second channel, and the frequency gap in parallel to a receiver”: [T]he “transmitting” step in claim 1 requires that the frequency gap be included in the transmitted signal. Inclusion of the frequency gap in the transmitted signal necessarily requires that the frequency gap be only partially filled -- but not fully filled -- with added data subcarriers at the time of transmission, because if the frequency gap were fully filled it would no longer exist at the time of signal transmission. Prelim. Resp. 23. Petitioner offers no explanation for how the language of claim 1 itself would allow for “partially” to encompass “completely.”” slip op. at 15
