Although Petitioner did not invoke inherency by name for the theories based on Seo or Nam alone, this is, in effect, the nature of Petitioner’s assertions, namely, voltage differentials in Seo and Nam would inherently remove fast charges. For example, with respect to Seo, Petitioner argues that “Seo teaches having a higher voltage on unselected WLs (e.g., adjacent WLs to the selected WL) during the first time period,” and “the ’342 patent recognizes [that] this voltage differential removes fast charges.” Pet. 35–36 (citing Ex. 1001, 12:24–34; Ex. 1003 ¶¶ 129–131) (emphasis omitted); see also id. at 82–83 (relying on the ’342 patent to support the contention that Nam teaches Limitation [1.D] because Nam “teaches having a higher voltage on unselected WLs (including WLs adjacent to the selected WL) relative to the selected WL during the first time period” (citing Ex. 1001, 12:24–34) (emphasis omitted)).

In particular, we were not persuaded that “Seo creates a large lateral electric field like the one described in Choi,” and, in any case, we disagreed that “Choi teaches that a large lateral electric field removes fast charges.” Id. at 15.

“the knowledge of one of ordinary skill in the art relating to charge-trap memory devices demonstrates fast charge removal. See Pet. 36, 81–82. And although Petitioner cites its declarant, Dr. Liu, for the proposition that “Seo discloses, and would have been understood to disclose, performing its read operation on charge-trap memories, which removes fast charges,” Dr. Liu does not cite objective evidence to support this assertion, aside from the ’342 patent itself. Id. at 36 (citing Ex. 1003 ¶ 136). Moreover, Dr. Liu’s testimony simply circles back to logic similar to that relied on with respect to the inherency theory, namely that, given certain similarities between Seo and the ’342 patent, Seo removes fast charges because the ’342 patent teaches removing fast charges, even though Seo does not explicitly teach doing so. See Ex. 1003 ¶ 136 (“[A] POSITA would have immediately understood from reading Seo that Seo is disclosing its read operation as applicable to Flash memories, including Flash charge-trap memories. And as the ’342 states, Seo’s operation would remove fast charges in a charge-trap memory.” (citing Ex. 1001, Abstract)). As already discussed, we disagree with this logic based on the lack of sufficient evidence to support its conclusion. See Dec. 13 (“Petitioner and Dr. Liu do not provide any objective evidence or explanation as to how or why a POSITA would have understood that Seo’s voltage amounts applied during Seo’s time periods operate the same way [as in the ’342 patent] on Seo’s memory device to generate fields with sufficient magnitude and duration to remove fast charges.”). Petitioner’s assertions regarding Nam suffer from the same shortcomings.

- Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Not reached
“A claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, “would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) if presented, objective evidence of non-obviousness. See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). As previously noted, the first factor regarding the scope of available prior art is the dispositive issue of this Petition, which is largely defined by the effective filing date of the challenged claims.” slip op. at 8

“Because we determine that no inter partes review will be instituted on IPR2024-01350, we find it unnecessary to exercise exclusive jurisdiction over the ’849 patent. See Paper 9, 9. Therefore, Petitioner’s motion for the Board to exercise exclusive jurisdiction over the ’849 patent is denied. Petitioner further requests that all briefing in this proceeding be provided to the Certificates of Correction and Petitions branches for their consideration, citing Patent Owner’s “duties of candor and good faith.” Id. at 2, 10.

“To prevail on its obviousness challenges, Petitioner must show that the ’848 patent is not entitled to the benefit of the ’330 application.

- BurdenDecided for patent owner
“1. The Burden of Persuasion “In an inter partes review . . ., the petitioner shall have the burden of proving a proposition of unpatentability by a preponderance of the evidence.” 35 U.S.C. § 316(e). That burden, termed the burden of persuasion, “is the ultimate burden assigned to a party who must prove something to a specified degree of certainty.” Dynamic Drinkware, LLC v. National Graphics, Inc., 800 F.3d 1375, 1378 (quoting Tech. Licensing Corp. v. Videotek, Inc., 545 F.3d 1316, 1326–27 (Fed. Cir. 2008)). That burden never shifts to the patentee. Id. at 1379. In order for an inter partes review to be instituted, “the information presented in the petition filed under section 311 and any response filed under section 313 [must] show[] that there is a reasonable likelihood that the petitioner would prevail.” 35 U.S.C. § 314(a).” slip op. at 9

The May 26, 2005 filing date of the ’330 application predates the December 1, 2005 publication date of Steuer 750, the August 13, 2013 issue date of Steuer 768, and the December 2, 2010 and May 27, 2010 publication and filing dates of Neumeier.10 Pet. 7; Ex. 1005, code (43); Ex. 1006, code (45); Ex. 1007, codes (43), (60).11 Therefore, Petitioner has not shown by a preponderance of the evidence that any of the asserted claims in the ’848 patent would have been obvious over the asserted combinations of Steuer 750, Steuer 768, and Neumeier.” slip op. at 22

“arguments presented by both parties, we find Petitioner’s evidence to be insufficient to carry its burden of showing Wang777 discloses or suggests claim elements 1.3, 6.3, and 10.3. More specifically, we find that Petitioner does not present persuasive evidence that Wang777 discloses or suggests the use of “a sequential order of at least two different obtained content identifiers in the play stream to identify a channel corresponding to the data samples.” Furthermore, Petitioner’s declarant, Dr. Russ, adds little, if any, persuasive value because his testimony is almost indistinguishable from Petitioner’s argument in the Petition and, as such, incorporates the same flaws. Compare Pet. 52–56 with Ex. 1003 ¶¶ 137–144. The reason Petitioner’s reliance on paragraph 72 of Wang777 is unavailing is because we are not persuaded that it discloses or suggests using two different content identifiers to identify a channel.

“We agree with Patent Owner that a person can qualify as a skilled artisan based on relevant industry experience in lieu of a formal degree. We also agree that ACR systems are relevant to the subject matter of the ’849 patent. We disagree, however, that industry experience with ACR systems is required to qualify as a skilled artisan. The ’849 patent describes a media usage monitoring and measurement method that relies on “known content recognition methods,” including known ACR. Ex. 1001, code (54), 5:48–54. The claimed invention relates to analyzing sample sequence data to enhance content identification and to establish channel identification. Id. at code (57), 15:14–32 (claim 1). The ’849 patent relies upon known ACR systems, but does not claim a new method of content recognition such that industry experience designing or implementing ACR systems is required. We accept that such experience may assist in providing relevant industry experience. For these reasons, we determine that a skilled artisan would have had a bachelor’s degree in electrical engineering, computer engineering, computer science, or an equivalent degree, with two years of relevant industry experience in digital media content delivery or designing or implementing ACR systems.
