    • Skill levelSkill level patent owner adoptedDecided for patent owner

      “Patent Owner argues for a slightly different level of ordinary skill in the art: “a bachelor’s degree in electrical engineering, computer engineering, computer science, or a similar field, along with one to two years of experience developing or programming video games or video game systems, or similar types of computer systems.” PO Resp. 2 (citing Ex. 2006 ¶ 29). Patent Owner further argues that the person having ordinary skill in the art “may have additional education that might substitute for some of the experience, and additional experience might substitute for some of the educational background.” Id. (citing Ex. 2006 ¶ 29). According to Patent Owner, Petitioner’s proposal does not require experience in programming video games. Id. at 3. However, Patent Owner states, “[t]his difference does not materially affect the analysis presented below.” Id. We see very little difference between the parties’ respective proposals. We adopt Patent Owner’s marginally more specific proposal. Additionally, because we would reach the same conclusions under Petitioner’s proposal, we agree with Patent Owner that this does not affect our analysis.” slip op. at 9

      “Patent Owner argues that the plain and ordinary meaning of “downloading” excludes “real-time fetching of data by a client from a server system.” PO Resp. 34; see also PO Sur-reply 16–17; Tr. 32:22–34:7. Because we need not expressly construe any claim terms, we do not construe any terms of the ’662 patent. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co. Matal, 868 F.3d 1013, 1017 (Fed.

      “date of the ’662 patent, Ho is not a “printed publication” within the meaning of 35 U.S.C. § 311(b). PO Resp. 30–33; PO Sur-reply 15–16. The Federal Circuit has rejected this argument, holding that: a published patent application is, by its literal terms, a “printed publication.” So, when § 311(b) permits IPR challenges based upon “prior art . . . printed publications,” it includes within its literal scope challenges based upon a published patent application. And, by virtue of § 102(e)(1), a published patent application—this specific type of “printed publication”—is deemed prior art as of its filing date. Therefore, the plain language of §§ 311(b) and 102(e)(1) permits IPR challenges based upon published patent applications, and such published patent applications can be deemed prior art in IPRs as of their filing date. Lynk Labs, Inc. v. Samsung Elecs. Co., 125 F.4th 1120, 1127 (Fed. Cir. 2025). Thus, Petitioner asserts permissible grounds of unpatentability under 35 U.S.C. § 311(b) by arguing that claims 1–20 are unpatentable under 35 U.S.C. § 103(a) on the basis of Ho, which is a prior art printed publication, and either Aoki or Kim.” slip op. at 11

      “A person having ordinary skill in the art would have combined Aoki’s teaching of using user-identification information as part of the request for an advertisement with Ho’s system, which also teaches a client device sending information to a server to request hot spot information, such as advertisements. See Ex. 1003 ¶¶ 103–107, 111, 114, 117. Because both Ho and Aoki are directed to improvements in game design and monetization from using advertisements (id. ¶ 106; Ex. 1004, 1:26–28; Ex. 1005 ¶¶ 6–8), a person having ordinary skill in the art would have looked at both Ho and Aoki and combined the relevant features with a reasonable expectation of success (Ex. 1003 ¶¶ 103, 106, 117). A person having ordinary skill in the art would have appreciated that using Aoki’s teaching of sending user-identification information with Ho, which includes sending information with a request for information relating to interactive information elements (hot spots), allows for targeted advertisements, which was a known advantage in advertising.

      “We have considered the parties’ citations to the specification and find examples that support Petitioner’s view that the term “entity” is broad enough to encompass dispatchers and individual users. See e.g., Ex. 1001, 3:52–4:5, 7:18–20, Fig. 1). However, we find no disclosure that redefines “entity” or excludes dispatchers and individual users from the category of “entity.” Patent Owner’s best examples (e.g., Ex. 1001, 1:15–21, 3:59–62) are no more than non-limiting examples.

Sakamoto expressly discloses setting the ratio of negative to positive electrode active material in the range of 1.05 to 1.30. Ex. 1005 ¶ 8.

These disclosures are sufficient to explain why one of ordinary skill in the art would have found it obvious to select the ratios disclosed in Sakamoto in Yamaki. Id. ¶ 8 (providing a secondary battery with a capacity ratio between 1.05 and 1.30 and noting that by setting the ratio within this range the resulting secondary lithium battery is “safe due to low risk of heat being generated and an explosion occurring”). We also disagree that Sakamoto teaches away from elevated voltages or from increasing the amount of lithium in circulation. See PO Resp. 29. Contrary to Patent Owner’s arguments, Sakamoto provides no general teaching against using a charge cut-off voltage above 4.2 V, or against increasing the level of lithium in circulation. Nor does Sakamoto “criticize, discredit, or otherwise discourage” the claimed invention. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Rather, Sakamoto warns against setting the reversible capacities of the positive and negative electrode substantially equal as this may result in excess lithium plating on the surface of the electrode. Ex. 1005 ¶¶ 6, 8. We agree with Petitioner that this disclosure would lead one of ordinary skill in the art to design a battery with a higher capacity in the negative electrode active material than the positive electrode active material.

      “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.

When I weigh the evidence, I find it to be one-sided, with all of the expert testimony weighing against Petitioner or avoiding the issue altogether. Thus, I would not find that Petitioner has met its burden to prove, by a preponderance of the evidence, that Zhao teaches claim limitation 1e. Moreover, even if the Majority is correct about how Zhao’s RCR algorithm works, all that shows is that the detection of object presence in a previous image can be used to disambiguate segments (e.g., limbs) of an already detected object (e.g., a person), not that it can be used to detect the object in the image in the first place, as required by the claim language.

Reasons for Obviousness Based on Zhao On a limitation-by-limitation basis, Petitioner’s contentions of “obviousness” are primarily assertions of how a POSITA would have understood Zhao’s disclosures. For example, with regard to claim 1, Petitioner repeatedly asserts how “a POSITA would have understood Zhao” (Pet. 13, 18, 21, 27) and for each limitation contends that Zhao “disclosed or at least rendered obvious” (or a variation thereof) the limitation (id. at 13– 15, 17–18, 21, 23, 25–27). We will, accordingly, address these “obviousness” contentions when addressing the respective limitations.” slip op. at 25

      “Petitioner contends that a person of ordinary skill in the art “would have at least a Ph.D. in chemistry, metallurgy, or material science or material engineering” or, in the alternative, “would have a Bachelor of Science or Master of Science degree in one of these disciplines plus experience involving the use and design of dissolvable metal alloys for use in creating tools and other downhole parts for well drilling or completion activities.” Pet. 13–14. Patent Owner does not oppose Petitioner’s contentions regarding the level of ordinary skill in the art. PO Resp. 12 n.4.

      “With respect to claim 19, Petitioner proposes constructions for the terms “in situ precipitate” and “a plurality of particles of said in situ precipitate having a size of no more than 50 µm.” Pet. 11–12. With respect to claims 76–81, Petitioner proposes a construction for the term “wherein said additive material includes one or more metal materials selected from the group consisting of 0.1–35 wt. % copper, 0.1–24.5 wt. % nickel and 0.1–20 wt. % cobalt.” Id. at 13. Patent Owner contends no claims require construction for purposes of this Decision. PO Resp. 12 n.4, 17–18; Mot. 16–17. Upon review of the prior art of record, we determine that no claim terms require express construction for purposes of this Final Written Decision. See Realtime Data, LLC v.

      “Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed. Cir. 2001) (noting that a description of the “present invention” as having a particular structure “is strong evidence that the claims should not be read to encompass the opposite structure”). Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan. Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed. Cir. 2011) (noting that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority . . . Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120”). Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28. In view of the foregoing, we are not persuaded that Patent Owner has demonstrated that the inventors of the priority applications were in possession of a magnesium cast composite that included less than 50 wt. % magnesium, or greater than 50 wt. % additives. As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

    • Disclosure Requirements (§112) › Definiteness (Nautilus)DefiniteIndefiniteMixed

      “The definiteness requirement of § 112(a) is satisfied when “a patent’s claims, viewed in light of the specification and prosecution history, inform those skilled in the art about the scope of the invention with reasonable clarity.” Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898, 910 (2014); see 37 C.F.R. § 42.100(b) (changing the claim construction standard used to review a claim proposed in a motion to amend from the broadest reasonable construction to the “same construction standard that would be used to construe the claim in a civil action under 35 U.S.C. [§] 282(b)”). Proposed substitute claim 104 generically requires “in situ precipitate” and also a specific type of in situ precipitate: “in situ galvanically-active intermetallic precipitate.” Mot. Appendix A. Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence. Mot. Reply 4. As such, we do not find that this part of proposed substitute claim renders claim 104 indefinite.” slip op. at 22

      “3. “the rendered first webpage” Claim limitation 1dii recites “replacing the first and second objects within the 3D space with a window within a two-dimensional (2D) space in response to receiving the interaction, wherein the window includes the rendered first webpage.” Petitioner does not propose a construction for the term “the rendered first webpage” in the Petition. Pet. 13–14. Nevertheless, Patent Owner contends in the Patent Owner Response that “‘the rendered first webpage’ is the webpage that was requested by the user via the ‘first input’ from which the ‘first image’ was captured.” PO Resp. 13. As Petitioner summarizes, “[a]ccording to Patent Owner, ‘the rendered first webpage’ presented in 2D space ‘is the version that was previously received and rendered (e.g., stored in memory) from which the first image was captured. It is not a ‘live’ webpage from the Internet.’” Reply 6. Despite not proposing a construction in the Petition, Petitioner, in the Reply, asks us to construe “the rendered first webpage” to include either the previously received and rendered first webpage or a new (so called “live”) version of the first webpage rendered in response to receiving the user interaction of claim limitation 1dii. Reply 6–7. The plain and ordinary meaning of claim 1 supports Patent Owner’s argument. “To begin with, the context in which a term is used in the asserted claim can be highly instructive.” Phillips, 415 F.3d at 1314 (“To take a simple example, the claim in this case refers to ‘steel baffles,’ which strongly implies that the term ‘baffles’ does not inherently mean objects made of steel.”). Here, claim 1 refers to replacing the first and second objects with “the rendered first webpage,” which implies that the objects are not replaced with just any version of the first webpage. “Rendered” is in the past tense, suggesting a webpage that previously has been rendered. This is a clear reference to limitation 1ci, “rendering the first and second webpages.” Dr. Fuchs’ testimony is instructive. According to Dr. Fuchs, a skilled artisan “would have known that webpage rendering was a ubiquitous process for converting raw HTML code received from a web server into visible content.” Ex. 1003 ¶ 104. According to Dr. Fuchs, “[w]ebpage rendering is a core functionality of virtually all web browsers, and it would have been obvious to a [person of ordinary skill in the art] that rendering is a prerequisite step to obtaining ‘screen snapshots of actual web pages,’ as explained in Robertson’s companion Data Mountain paper.” Id. ¶ 105 (citing Ex. 1030, 5). Dr. Fuchs testifies that a skilled artisan “would have understood that Robertson’s 3D-GUI captures images of the rendered (first/second) webpages to obtain the webpage images on the object thumbnails.” Id. ¶ 107. Similarly, Dr. Fuchs testifies that “Gettman’s technique involves ‘cach[ing]’ ‘bitmap screenshots’ (captured first/second images) of rendered (first/second) webpages in local memory.” Id. ¶ 108.
