“Petitioner and Patent Owner propose constructions for all, or a portion of, the term “Formula I, XCF3(I), where X is a C2 unsaturated, substituted, alkyl radical.” Pet. 17–19 (proposing a construction for the term “C2 unsaturated, substituted, alkyl radical”); PO Resp. 12–15. Neither party contends, however, that express construction of this claim term, or any other term in the ’808 patent, would impact any of Petitioner’s or Patent Owner’s arguments in this proceeding. Accordingly, we determine that no claim terms require construction for purposes of this Final Written Decision. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”).” slip op. at 7

“art. Patent Owner, relying upon the testimony of Dr. Bivens, asserts that one of ordinary skill in the art would have had either: “(1) a bachelor of science degree in a specialty area (such as chemical engineering or chemistry) and five years of work experience in developing/testing refrigerants, blowing agents, and propellants, or (2) a Ph.D. or masters of science degree and 2-3 years of work experience.” PO Resp. 12 (citing Ex. 2034 ¶¶ 21–24). Patent Owner’s identification of a person of ordinary skill in the art is uncontroverted and is consistent with the prior art of record. Accordingly, we adopt Patent Owner’s identification for purposes of this Final Written Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“patent met a long-felt but unresolved need or were commercially successful, we have been directed to no persuasive evidence to demonstrate these propositions. See Graham, 383 U.S. at 17–18 (noting that “long felt but unsolved needs” and commercial success may be utilized as indicia of nonobviousness). Indeed, we have been directed to no persuasive evidence that a mixture of CO2 and a fluoroalkene of claim 1 has ever been used commercially, or that such a mixture was considered by those of ordinary skill in the art to have met a long felt but previously unresolved need.9, 10 See Tr. 51:24–52:7; Pet. Reply 9 (asserting that Patent Owner “has provided no evidence, post- or pre- issuance of the ’808 patent, of the commercial advantages or uses of the claimed compositions”). With respect to Petitioner’s prior patent applications, although Patent Owner initially characterizes these applications as relating to CO2 and partially fluorinated hydrocarbons, Patent Owner later notes that these patents are directed to blends of HFO-1234yf, CO2, and R-134a. PO Resp. 44; Ex. 2024, 12 (arguing in support of patentability that “[t]he specific 9 To be relevant, Patent Owner must show that the asserted secondary considerations are attributable to “the merits of the claimed invention beyond what was readily available in the prior art.” Asyst Techs. v. Emtrak, Inc., 544 F.3d 1310, 1316 (Fed. Cir. 2008). Here, Inagaki discloses using compounds within the scope of claim 1 of the ’808 patent as refrigerants. Patent Owner presents no persuasive evidence that the addition of CO2 to the compounds of Inagaki, or the particular ranges recited in claim 1, resulted in a product that met a long felt but unresolved need or resulted in a commercially successful product beyond what was provided in Inagaki. Thus, we are also not persuaded that there is any nexus between the asserted secondary considerations and the features of claim 1 that are not disclosed in Inagaki. 10 As Patent Owner has not demonstrated any commercial use of the claim 1 compounds for any purpose, or provided evidence that those of skill in the art considered the claimed compounds to have met an unresolved need in the art, this analysis applies equally to the dependent claims of the ’808 patent, which each depend, directly or indirectly, from claim 1. combination of trans-R1234ze and R134a and CO2 simply is not suggested in Singh, let alone in the amounts defined in claim 1”). Patent Owner does not explain sufficiently why Petitioner’s arguments directed to the patentability of a blend of three compounds, utilized in specific proportions, are necessarily applicable to the combination of Kruse, Inagaki, and Butler proposed by Petitioner, or why these arguments are otherwise strong evidence of the nonobviousness of claim 1 of the ’808 patent. Based on the foregoing, and upon review of Patent Owner’s arguments as a whole, we are not persuaded that Patent Owner’s proffered objective evidence of nonobviousness is strong or tends to refute Petitioner’s arguments and evidence with respect to the obviousness of claim 1 of the ’808 patent.” slip op. at 25

“Although the sections of the Specification of the ’237 Patent cited by Petitioner relate to disk size, that size is a direct result of the number of records in the data set. Claim 1, for example, recites “using the received features extracted from the media work to perform a sub-linear time search of extracted features of identified media works.” For that claim, under our adopted claim construction, the size of the data set would be the number of extracted features of the identified media works. It would not be logical to assume that the size of the data set would be the length of an individual record or the amount of disk space the data set occupies when the number of extracted features would be readily available. Although disk space could be used as a measure, it would be variable with respect to the format of the disk space, for example. Therefore, we are not persuaded that disk space should be used as a determinant of data set size in the construction of “sub-linear search.” As such, the data set would be the number of extracted features, in claim 1, irrespective of the exact number of commercials or frames.” slip op. at 7

“ii) “non-exhaustive search” With respect to the claim term “non-exhaustive search,” Patent Owner emphasizes that a non-exhaustive search makes a comparison without all possible matches but does not concern itself with whether all data within all possible matches have been compared. PO Resp. 6–7. Petitioner does not dispute the construction, and we remain persuaded that a “non-exhaustive” search need not consider all data within all possible matches, but rather should be exhaustive or non-exhaustive with respect to the number of records in a database. See Dec. 5–7.” slip op. at 8

“Petitioner responds that the statements in the Specification do not rise to the level of lexicography or disavowal. Reply 4–5 (citing Facebook, Inc. v. Pragmatus AV, LLC, 582 F. App'x 864, 868 (Fed. Cir. 2014); Renishaw PLC v. Marposs Societa' per Azioni, 158 F.3d 1243, 1249 (Fed. Cir. 1998)). We agree, given that the cited portion provides that an approximate nearest neighbor search may be an example of a sublinear search, but not that all approximate nearest neighbor searches must be sub-linear. Additionally, Patent Owner has not provided persuasive evidence that all approximate nearest neighbor searches must be sub-linear, other than the citation to the Specification. As well, similar to our discussion of neighbor searches above, we are not persuaded that if an approximate nearest neighbor search happens to arrive at an exact match, that would negate the nature of the search. We are persuaded that an approximate nearest neighbor search would depend on the search methodology and not on the specific results obtained. Additionally, as Petitioner points out, the instant claims confirm that sublinearity is not necessarily required for an approximate nearest neighbor search. Reply 5–6. Claim 33 recites, in part, a “sublinear approximate nearest neighbor search,” whereas claims 9 and 12 simply recite an “approximate nearest neighbor search,” without the sublinear modifier. Interpreting all recitations of approximate nearest neighbor searches as intrinsically sublinear would render the limitation in claim 33 superfluous. Id. (citing Phillips v. AWH Corp., 415 F.3d 1303, 1314 (Fed. Cir. 2005); Digital-Vending Servs. Int’l, LLC v. Univ. of Phoenix, Inc., 672 F.3d 1270, 1274–75 (Fed. Cir. 2012)). For this additional reason, we remain persuaded that an approximate nearest neighbor search corresponds to “identifying a close match that is not necessarily the closest match,” without a requirement of being sublinear.” slip op. at 9

“in which he agrees that Iwamura’s system compares a work to be identified with each reference work in the database. PO Resp. 26–28 (citing Ex. 2006, 207:18–23, 223:2–8, 247:18–20, 269:19–270:2, 271:19–21); see also Tr. 17:17 (Petitioner conceding at oral hearing that “every song is looked at”). Dr. Moulin also acknowledges that if a non-exhaustive search is one that does not look at each of the melodies in the database, Iwamura discloses an exhaustive search rather than a non-exhaustive search. Ex. 2006, 233:24– 234:14; see PO Resp. 27. Despite Dr. Moulin’s testimony and Iwamura’s description of a search that compares an input melody to each melody in the database, Petitioner contends that Iwamura discloses a non-exhaustive search. First, Petitioner submits that Iwamura specifically identifies its peak note search as a non-exhaustive search because the “search speed using peak notes is 20% of a brute force search.” Pet. 9–10 (quoting Ex. 1012, 9:8–11); Reply 7–8 (citing Ex. 1012, 9:7–11; Ex. 2005 ¶ 82; Ex. 2001). We agree with Patent Owner, however, that Iwamura’s peak note search accelerates a search within a single comparison between a work to be identified and an individual record in the database, while still comparing the work to each record in the database. See PO Resp. 29–30. In other words, the peak search technique may improve the efficiency of an individual comparison between an entered melody and a reference melody in the database, but it is still an exhaustive search because it compares the entered melody with each musical work in the database, as confirmed by Petitioner’s declarant, Dr. Moulin. Id. (citing Ex. 2006, 269:19–270:2). Petitioner further argues that Iwamura discloses a non-exhaustive search because the search can be accelerated by stopping the search when computations “exceed[] a certain limit.” Pet. 10 (quoting Ex. 1012, 7:56– 57). We agree with Patent Owner that this disclosure also refers to improving the speed of a comparison between the work to be identified and a single record in the reference database. See PO Resp. 32 (citing Ex. 2005 ¶ 179). As Dr. Karypis explains and Dr. Moulin confirms, when the total absolute difference computed between the entered melody and a particular reference melody exceeds a certain limit, the computation stops, and the search shifts to the next peak range comparison within the same record. Id. at 32–35 (citing Ex. 2005 ¶¶ 180–81; Ex. 2006, 241:24–242:2). Thus, Iwamura’s computation “limit” does not describe a non-exhaustive search because Iwamura still compares a work to be identified with each reference melody in the database.” slip op. at 16

“specifically requires a WF6 flow rate of 10–40 sccm,” see Ex. 2002 ¶¶ 89– 90, we note that the discussion of predetermined flow rates in Emesh is in relation to the “preferred embodiment,” and not the invention as a whole. Ex. 1009, 4:63–65, 5:36–42. Moreover, dependent claim 2 recites that “the flow rate of WF6 is maintained in the range 10 to 40 sccm,” raising a presumption that the WF6 flow rates of Emesh may be broader than 10 to 40 sccm. Id. at 12:39–41; see Bancorp Services v. Sun Life Assur. Co. of Canada, 687 F.3d 1266, 1275 (Fed. Cir. 2012) (noting that “the presence of a dependent claim that adds a particular limitation raises a presumption that the limitation in question is not found in the independent claim”). Thus, we are not persuaded that Emesh teaches away from, or would otherwise discourage one of ordinary skill in the art from modifying, the disclosed WF6 flow rate. Based on the foregoing, we credit the testimony of Dr. Rubloff and find that one of ordinary skill in the art would have sought to modify the WF6 flow rate of Emesh within the range of 40 to 133 sccm (while maintaining a H2/WF6 ratio of 6) with a reasonable expectation of success.” slip op. at 18
