“Petitioner asserts that [t]he person of ordinary skill in the art (POSA) would have been an M.D. and/or Pharm. D who would have completed training in medical oncology, particularly in the field of gastrointestinal (GI) cancers, or a Ph.D. in clinical pharmacology, pharmaceutical sciences, pharmaceutics, and/or drug delivery, also particularly in the field of GI cancers, or their equivalents, along with at least 1-2 years of post-doctoral experience. Pet. 26 (citing Ex. 1002 ¶¶ 44–46). Patent Owner states that, for purposes of this proceeding, it does not dispute Petitioner’s proposed definition of a POSA. PO Resp. 8. Based on the entirety of the trial record, we adopt Petitioner’s proposed definition of a POSA’s skill level because it is consistent with the skill level reflected in the disclosures of the ’552 patent and prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art may reflect an appropriate level of skill in the art).” slip op. at 9

“We decline to discount Dr. Oberstein’s opinion based on the alleged conflict of interest and bias. Dr. Oberstein testified that the consulting fees he receives from Patent Owner reflect a small fraction of his income. Ex. 1210, 402:21–403:9. We also agree with Patent Owner that an oncologist prescribing an FDA-approved regimen does not evince bias. See Sur-reply 23; see also Ex. 1206, 49 (showing NALIRIFOX is a category 1, NCCN-preferred first-line therapy for metastatic pancreatic cancer), 69 (explaining category 1 is based upon high-level evidence). Petitioner also contends that Dr. Oberstein “offers conclusory opinions,” “fails to properly apply the law, continues to look at each reference in isolation, refuses to acknowledge logical suggestions in the art, and imports new limitations into the claims.” Reply 3–4.

“In the DI, the Board stated that the ordinary understanding of a claim reciting a “method of treating metastatic adenocarcinoma of the pancreas” that comprises “administering an antineoplastic therapy to the patient” in order “to treat the metastatic adenocarcinoma of the pancreas” is that the “treatment” would have more than a de minimis therapeutic benefit or efficacy for the patient being treated.

“The parties, however, disagree over whether each recited dose must be the starting dose. Petitioner argues that “claim 1 requires that the method of treatment is a first-line therapy, but does not require that the claimed doses be used as a starting dose.” Paper 51, 1. In contrast, Patent Owner argues that “[t]he specification describes that the recited dose of each drug is a ‘starting’ or ‘initial’ dose.” Paper 50, 2 (citing Ex. 1001, 13:38–45, 30:5–7). For purposes of this Decision, we do not need to resolve this dispute. See Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (stating that claim terms need only be construed to the extent necessary to resolve the controversy). As explained below, we agree with Petitioner that, even if claim 1 recites the starting dose for each drug, Petitioner has shown, by a preponderance of the evidence, that the prior art teaches each dose and a POSA would have had a reason to start with the recited doses. See infra Section II.G.3; Paper 51, 3 n.2. Because we find that the prior art teaches or suggests the claimed subject matter even under Patent Owner’s proposed narrower claim interpretation, we need not further construe the disputed claim language.” slip op. at 16

“We do not agree with Petitioner that the fact pattern before us is analogous to Rembrandt. The rationale to combine the teachings of Inoue and Smith provided in the Petition focuses on replacing incandescent bulbs with LEDs, and includes the generic statement that “[t]he numerous record-supported advantages, set forth in Smith provide a clear motivation for use of the teachings of Smith as applied to Inoue, so as to enjoy the advantages set forth in Smith.” Pet. 47. The testimony in Dr. Schubert’s Declaration at pages 99–100 cited in support of Petitioner’s Reply arguments was not cited or otherwise referenced in the Petition. See Pet. 46–55. We find that the Petitioner’s Reply is not responsive to the Institution Decision and is improper because it presents a new rationale to combine the teachings of Inoue and Smith that was not expressed in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Petitioner could have presented its rationale to make out a prima facie case of unpatentability in the Petition. See 37 C.F.R. § 42.23; CTPG § II.I. Accordingly, we do not consider Petitioner’s new rationale to combine the teachings of Inoue and Smith presented for the first time in the Reply. Based on the entire record, but not including Petitioner’s new rationale and newly cited support to Smith and Dr. Schubert’s testimony (Exs. 1013, 1017) presented for the first time in the Reply, we are not persuaded that Petitioner sets forth in the Petition sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to one of ordinary skill in the art to modify the circuit of Inoue to include a light source or LED light source with a twinkling or flashing effect in view of Smith’s teachings. See Pet. 46–47, 49–50, 51–53, 55.

Based on the entire record and including the reasons explained above in Section II.D.2. addressing anticipation of claim 1 by Inoue, we determine Petitioner shows by a preponderance of the evidence that the subject matter of claims 1 and 10 would have been obvious over Inoue and Holler.

“We observe that, aside from Declaration testimony of Mr. Altamura and accompanying exhibits, Patent Owner does not offer any additional evidence to establish reduction to practice. An inventor’s testimonial assertion of inventive facts requires corroboration by independent evidence. Brown v. Barbacid, 276 F.3d 1327, 1335 (Fed. Cir. 2002). The purpose of the corroboration requirement is to prevent fraud, by providing independent confirmation of the inventor’s testimony. Kridl v. McCormick, 105 F.3d 1446, 1450 (Fed. Cir. 1997). Without the requirement of independent corroboration, there would be a great temptation to commit perjury and the adverse party would be effectively precluded from a successful rebuttal. Price v. Symsek, 988 F.2d 1187, 1194–95 (Fed. Cir. 1993). A rule of reason applies to determining whether the inventor’s testimony has been corroborated. See id. at 1195. “The rule of reason, however, does not dispense with the requirement for some evidence of independent corroboration.” Coleman v. Dines, 754 F.2d 353, 360 (Fed. Cir. 1985). Accordingly, based on the entire record, we find that Mr. Altamura’s Declaration testimony is uncorroborated. Yu is prior art to the ’252 Patent because Patent Owner is unable to establish actual reduction to practice earlier than the July 31, 2006, filing date of Yu.” slip op. at 51

“arguments, we agree with Patent Owner’s proposed construction that requires the server to conduct a compatibility check. We start with the express claim language. Claim 10 recites: determining, by the server, applicable settings for the selected vehicle, the applicable settings being settings that are preferred to be set as identified from the user profile and are compatible with settings that are settable in the selected vehicle. Ex. 1001, 33:10–14 (emphases added). The express claim language requires that the server determine applicable settings. Those applicable settings, determined by the server, must also be compatible with vehicle settings. As such, the plain and ordinary meaning of the claim language expressly requires that the server make a determination of applicable settings that are defined as being compatible with vehicle settings.” slip op. at 14

“However, contrary to Dr. Almeroth’s testimony and Petitioner’s position, Xiao’s server already does not attempt to command vehicles to do things they cannot do. Xiao teaches that server 118 generates commands for command codes that exist and are settable in the vehicle. Ex. 1010 ¶¶ 102– 103. As such, if there is no corresponding automobile setting, then Xiao’s server would not list those command codes for retrieval and would not send a command based on that retrieved command code to control the automobile systems to achieve the operator’s desired settings because that command code is not in the database. Our understanding of Xiao is further supported by Dr. Almeroth’s testimony: By listing them in the table of automobile command code information 606, Xiao shows that there are particular settings compatible with particular automobiles and particular desired settings. Thus, Xiao demonstrates the necessarily present characteristic that certain settings (e.g., commands) are compatible with certain automobiles. Ex. 1009 ¶ 96 (emphases added). We note that Dr. Malek further explains “the nonsensical result achieved by the combination would be that Xiao’s server, at best, in response to the command request issued by the operator, could ‘look up’ a command code to apply a vehicle-specific setting to that automobile 112, only to find that there is ‘none.’” We agree with Dr. Malek that there is a “None” command code in Xiao’s database when Xiao’s database already stores settings that are known to be settable in a specific vehicle per the operator’s preferences. Ex. 2011 ¶ 135. Thus, based on the complete record, we determine that Petitioner has not demonstrated by a preponderance of the evidence that Xiao in combination with Hayashi render claim 10 obvious.” slip op. at 79

“We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage. In view of the foregoing, we construe “charge cut-off voltage” in claims 1 and 5 as “the maximum value to which the battery is configured to be charged.” PO Resp. 18; Ex. 2008, 217:6–11; Pet.

Under this standard, we construe the claim “in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” Id.

“What these cases and examples clearly articulate, is that whether there is sufficient description in an anticipation reference for linking different disclosures, elements, and embodiments, is particularly case and fact dependent. Moreover, a finding of anticipation resting upon a reference’s disclosures of elements in different embodiments turns on whether an ordinarily skilled artisan would understand that the reference suggests arranging the elements of the embodiments to one another in the same way as the challenged claims. For the reasons that follow, we determine that there is sufficient description and teaching in Kim such that the “combined button” disclosed by Kim, for example in Figure 10(b), can be the same “combined button” as discussed in the embodiment of Figure 18.” slip op. at 28
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“As to Patent Owner’s first and second arguments, as we discussed in detail above with respect to anticipation, we find that there is sufficient evidence in Kim itself of contextual and even express links between the various combined button embodiments and Figure 18. Section II.D.2.b)(1)– (4). We have already determined “that one of ordinary skill in the art would understand Kim to disclose the ‘combined button’ structure and function that could be implemented on the face or sidewall of a device.” Id. We likewise determine, based on the same evidence, that a person of ordinary skill in the art would have understood Kim to suggest that the combined button structure and function, for example in the embodiment of Figure 10(b), could be implemented in an opening on the face or sidewall of a device. Obviousness does not require an instruction manual on how to physically incorporate or combine the disclosures of two embodiments in a reference. As KSR informs us, “in many cases a person of ordinary skill will be able to fit the teachings of multiple patents together like pieces of a puzzle.” KSR, 550 U.S. at 420. Moreover, in this case we have only one prior art patent, Kim, so at least the pieces of the puzzle are all in the same box. The persuasive testimony of Dr. Berger that “a person of ordinary skill in the art would have been familiar with electronic devices with sealed and/or insulated button assemblies, and would understand that those assemblies were not limited to the front face of a device,” is unrebutted in this case. Ex. 1003 ¶ 110. “A person of ordinary skill is also a person of ordinary creativity, not an automaton.” KSR, 550 U.S. at 421. Given the background knowledge of a person of ordinary skill in the art in conjunction with the motivation and teachings in Kim itself for placing sufficient motivation to support the combination of Kim’s Figure 10(b) embodiment with the sidewall placement of the combined button taught in Figure 18 for obviousness purposes. It is well-settled that a single prior art obviousness reference itself can provide motivation for the combination. See General Elec. Co. v. Raytheon Techs. Corp., 983 F.3d 1334, 1352 (Fed. Cir. 2020) (Reversing the Board’s finding of nonobviousness over a single prior art reference, the Court explained that “the Board’s approach would require a motivation to combine each element of the claim—even those present together in a reference. This analysis unduly dissects prior art references into collections of individual elements, requiring a party showing obviousness to re-do the work already done in the prior art reference.”). Patent Owner’s third argument is unavailing because although Dr. Anthony testifies that “implementing the fingerprint sensor assembly of Kim’s Figure 10 embodiment in the ‘lateral surface’ of Kim’s Figure 18 embodiment would have complicated the manufacturing process for the resulting mobile device,” Dr. Anthony does not provide testimony or evidence that implementing the combined button on the sidewall would have been difficult or beyond the level of ordinary skill in the art. Ex. 2009 ¶ 73. We credit Dr. Berger who explains persuasively that “[p]rior to the ’619 patent’s earliest alleged priority date of June 19, 2017, a person of ordinary skill in the art would have known that a mobile electronic device could include one or more button assemblies in a sidewall.” Ex. 1003 ¶ 47 (citing Ex. 1013, 4:40, 19:42–20:4, Figs. 13B, 17, 19A, 19B). It is well-settled that a person of ordinary skill can use his or her ordinary skill, creativity, and common sense to make the necessary adjustments and further modifications to result in a properly functioning device. See KSR, 550 U.S. at 418 (“the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.”).” slip op. at 43

“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.

“review of the record, we find that Petitioner fails to articulate an adequate rationale for the combination of Goss and House. The Petition contains only a single sentence addressing the issue, without any citation to record evidence or declaration support. See Pet. 46. In addition, the assertion merely states the conclusion that a “PHOSITA would understand that there is a rational underpinning to combine the teachings of Goss and House as required under patent law because both are related to cat litter having similar characteristics.” Id. This assertion, at most, addresses the fact that Goss and House are in the same field or that they are analogous art, but does not explain why a PHOSITA would have been motivated to combine Goss and House. See id. In addition, the Petition lacks sufficient explanation of how Petitioner proposes to combine Goss and House. See Pet. 46–53. Instead, when Petitioner relies on House in this challenge, it appears to be a back-up argument in the event that we find Goss fails to disclose the limitation. Merely stating that Goss and House both disclose a limitation does not explain which aspects of House Petitioner proposes adding to Goss or what the resulting litter composition would look like. See id. The details of the resulting litter based on the combination of Goss and House matter here because it could impact whether all limitations of a given claim are satisfied by the combination. For example, Petitioner relies exclusively on specific examples from Goss for the 47% surface area limitation, but adding some aspects of House’s litter components to meet other limitations could undermine Petitioner’s reliance on Goss’s specific examples. The failure of the Petition to set forth a specific combination elides these issues. See Pet. 46–51. Petitioner’s Reply arguably addresses some of these concerns by providing a more fulsome motivation section, backed by new expert testimony, and specific litter examples based on Goss and various cellulose filler materials allegedly disclosed by House.

“We agree with Patent Owner’s contention that the emphasized sentence defines the term “content-related.” See PO Resp. 15–16 (Patent Owner arguing that “[t]here are thus three strong indications of lexicography: (1) ‘content-related’ is set off by quotation marks; (2) the patentee used the word ‘is’ to describe the term ‘content-related’; and (3) the patentee states what ‘content-related’ is ‘understood to mean.’” Nor does Petitioner disagree that the sentence is definitional. See Tr. 8:15–16 (referring to the “term content-related as it’s defined in the specification”). Indeed, in the Starz litigation, the district court also treated the sentence as definitional, a fact that we find significant as a matter of comity. See Ex. 1018, 111:24–112:1 (district court judge stating at Markman hearing, “I’m going to adopt . . . the express definition provided in the specification”). But like the district court, we discern insufficient reason to adopt the additional gloss that Patent Owner seeks to apply to the definition of “content-related.” That is, Patent Owner proposes that we additionally construe the phrase “syntactical meaning” within the definitional statement to arrive at Patent Owner’s proposed construction. PO Resp. 16–20. According to Patent Owner, “[t]he specification makes clear, through its use of consistent and repeated examples, that ‘syntactical meaning’ requires a specific relationship between the data segments within a data file: succeeding data segments within a data file must be ordered so as to present the content in its intended sequence when rendered.” Id. at 17 (citing VirnetX Inc. v.

Patent Owner adds that the claims, the context provided by the problems solved by the ’794 patent, and the cross-examination testimony of Petitioner’s expert, Dr. Freedman, all support this additional aspect of Patent Owner’s proposed construction. Id. at 18–20. Relying on additional direct testimony by Dr. Freedman, Petitioner counters this position as “improperly import[ing] limitations from the specification that are not required by the claims” and “render[ing] other portions of claim 1 superfluous.” Reply 3 (citing Ex. 1016 ¶ 22); see Tr. 10:18–20 (Petitioner explaining at oral hearing that “the syntax information is simply just identification information which is used to find out what the order of the files is. But the identification information does not by itself indicate the order. It’s just an identifier.”). We agree with Petitioner that it would be imprudent to adopt Patent Owner’s additional gloss because, “[w]hile claims must be construed in light of the specification, . . . limitations from the specification are not to be read into the claims, . . . for ‘[i]t is the claims that measure the invention.’” Golight, Inc. v.

In addition, claims 1 and 9 already specify “sequentially outputting the first and second data segments according to their chronological sequence,” which supports Petitioner’s observation that requiring an additional sequential order to “content-related . . . data segments” renders other portions of claim 1 superfluous.

We agree in that Petitioner’s contentions in the Petition amount to no more than a conclusory assertion that a person of ordinary skill in the art “would have known” the predictive relationship limitation.

Petitioner’s arguments in the Petition are divorced from any analysis of Heller and fail to articulate why a person of ordinary skill in the art would have understood Heller to teach the predictive relationship in light of what was purportedly known more generally in the art.

While Petitioner purports to identify multiple references that teach a predictive relationship, Petitioner circumvents a legally sufficient obviousness analysis by choosing not to assert any of the references in combination with Heller, but to instead argue they all collectively show that “predictive relationships” were broadly known in the art. See Pet. 28–33. Rather than establish some broad understanding by persons of ordinary skill in the art concerning the predictive relationship limitation, Petitioner’s arguments make clear that each reference uniquely addressed the relationship between a particular sensor and the in vivo performance of the sensor.

Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015)) (alteration in original).” slip op. at 15

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
