    “Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). On its face, the language “energy transfer signal” does not specify any restrictions on the type of system in which it is utilized, nor its characteristics. In the context of claims 1 and 11, the “energy transfer signal” is the basis on which the “switch” operates, so as to “sub-sample and transfer energy from a first electromagnetic (EM) signal.” Ex. 1001, 50:63–65, 51:56–58. Accordingly, based on the claim language, the term “energy transfer signal” need only be a signal for operating a switch to sub-sample and transfer energy from an electromagnetic signal. That is its plain and ordinary meaning.” slip op. at 15

    “’686 patent broadly includes knowledge and experience as to RF circuit design. See supra § III.B. Petitioner contends that “Nevo’s transceivers [102a/102b] are for Bluetooth and IEEE 802.11,” and that a person of ordinary skill in the art would have understood that both protocols “required down-conversion in their receivers to obtain a baseband signal.” Id. at 35 (citing Ex. 1004, 4:45–50; Ex. 1002 ¶ 118). Nevo’s disclosure would have motivated a person of ordinary skill in the art to look to Avitabile, which provides the circuit level detail for down-converters. See Ex. 1006, Abstract. Avitabile specifically provides circuitry for down-conversion in the s-band frequency range, which is in the range of Bluetooth and IEEE 802.11 (2.4 GHz). Id. at Abstract, Figs. 6, 7. Accordingly, we determine a person of ordinary skill in the art would have been motivated to look to down-converters in the range of frequency needed, and would have been motivated to combine Avitabile’s teachings with those of Nevo, with a reasonable expectation of success.” slip op. at 55

    “Dr. Papanikolopoulos’s testimony that Kuwata teaches away from modifying its camera 22 to access an external server (such as Fisher’s Internet-enabled external data source) by stressing advantages of a self-contained camera-printer pair without external dependencies. See PO Resp. 15–16, 26–28 (citing Ex. 1005 ¶¶ 75, 77); Ex. 2001 ¶¶ 61–64. The cited disclosures in Kuwata simply do not discuss any advantages arising from a self-contained camera-printer pair without external dependencies, or any disadvantages arising from connecting camera 22 to an Internet server. See Ex. 1005 ¶¶ 75, 77. The cited disclosures instead tout the advantages arising from a camera manufacturer (rather than an end user photographer) specifying the image output control information CI for a specific camera-printer pairing, to reduce differences between an image as confirmed by the end user on the camera’s display and the image outputted by the printer. See id. That advantage, however, has nothing to do with whether camera 22 may or may not communicate with an Internet server. Indeed, rather than being self-contained as Patent Owner and Dr. Papanikolopoulos would have it, we find Kuwata’s camera 22 includes an I/O port for wired or wireless communication to transmit the camera’s image files GF / 10 to various printers 24 and various personal computers (PCs). See Ex. 1005, Fig. 4, ¶¶ 81, 85; Ex. 1003 ¶ 84; Pet. 14. Thus, Kuwata allows for and does not discourage communication between camera 22 and an Internet server such as Fisher’s external data source. In particular, Kuwata does not detract from the benefits of updating image output control information CI after the camera is manufactured, for example so that the camera can be paired with printers that were not yet on the market when the camera was manufactured. Moreover, Fisher recognizes that “a manufacturer may create various ancillary data files 418, and make the ancillary data files 418 available on a distributed computer network like the Internet for subsequent downloading and utilization by camera device 110.” Ex. 1006 ¶¶ 42, 55. That teaching in Fisher dovetails with Kuwata’s disclosure concerning camera manufacturers optimizing their cameras with various different printers, supporting Petitioner’s combination.

We acknowledge the ’807 Patent Specification discloses the words “the specific object” in the context of acknowledging or detecting the specific object in the image with the object acknowledgement section and retrieving an image from the database that contains the specific object after keywords are added to the image. See Ex. 1001, 4:18–24, 5:54–6:3, 7:28–31. Similarly, the Specification discloses the term “specific person” in the context of retrieving an image from the database that contains the specific person after keywords are added to the image. See Ex. 1001, 4:48–54. We further acknowledge that the Specification discloses a face image similarity determining section to determine if a face image is similar to a face image stored in the database.

The Specification further includes a passage, cited by Patent Owner, that discloses “if it is determined that the face image coincides to the face image which is contained previously [in a database] or is very similar to the face image which is contained previously, the information for such a human is proposed so as to expedite the user to confirm.” Ex. 1001, 9:18–22; see PO Resp. 16, 17, 19. Finally, we also acknowledge that the Specification further discloses an example of a database record that includes keywords, such as “Jiro” and “second eldest brother” for a human, and further discloses retrieving items from the database with the keyword “Jiro.” See Ex. 1001, 9:47–54, 10:41–58, Figs. 6, 9. however, do not rise to the level of disclaimer or a disavowal of the full scope of the claim term “similar to the object of the image previously contained in the database.” For example, Patent Owner does not direct us to any explicit statements or disclosures in the ’807 patent Specification that indicate a clear intention to limit “similar to the object” to “sufficiently similar to identify the specific object” using words or expressions of manifest exclusion or restriction.

    “A. Legal Principles “In an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)). This burden of persuasion never shifts to the patent owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). The burden of production, however, may shift between the petitioner and patent owner as arguments and evidence are presented during the proceeding. Id. A patent claim is unpatentable under 35 U.S.C. § 103 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 (“POSITA”) 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 determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of nonobviousness.2 See Graham v.

    “After review of the evidence, we determine that the record does not support Patent Owner’s construction of “expected contexts” as “a subset of the contexts in a context stack.” PO Resp. 16–17. The sole mention of “expected contexts” in the ’160 patent’s description is the following: “The knowledge-enhanced speech recognition may access a set of expected contexts that are stored in a context stack to determine a most likely context.” Ex. 1001, 13:66–14:2. This statement does not provide any definition for “expected contexts.” Although the ’160 patent’s description mentions a “set,” this is not the same as a “subset” as Patent Owner proposes in its construction. Similarly, claims 1, 12, 13, and 15 of the ’160 patent recite “one or more expected contexts” but do not elaborate further on what an “expected context” is. Likewise, “expected contexts” were mentioned but not discussed or defined in the prosecution history of the ’160 patent. Ex. 1012, 281, 305, 382. Consequently, we decline to restrict the construction of “one or more expected contexts” as Patent Owner proposes. To the extent that Patent Owner so argues, we do not consider “expected contexts” to require the use of “context specific matchers.” In this regard, the ’160 patent states that “knowledge-enhanced speech recognition may use context specific matchers that are able to identify context such as time, location, numbers, dates, categories (e.g., music, movies, television, addresses, etc.) and other context.” Ex. 1001, 14:2–6 (emphasis added). Hence, the ’160 patent states that “contexts” may be identified using “context specific matchers” but this is not required. We further decline to interpret “one or more expected contexts” to exclude “possible contexts” as Patent Owner argues. Simply put, we find no support in the ’160 patent or elsewhere that “expected contexts” cannot be “possible contexts” or that the two terms are mutually exclusive of one another. Although the ’160 patent mentions scoring “possible contexts” (Ex. 1001, 21:7–9), we find no reason why these “possible contexts” cannot also be “expected contexts.” Although we agree with Petitioner that “expected contexts” are ones” slip op. at 13

    “motivations to combine with reasonable expectation of success. However, in its Sur-reply, Patent Owner argues that Petitioner’s combination “makes no sense” because Ross’s contexts are arranged in order by recency of access such that no scoring is required to find a selected context, whereas Kennewick scores every context in the context stack to select a context. PO Sur-reply 9–10. Patent Owner further argues that Ross’s context grammars are fixed whereas Kennewick’s are dynamic according to prior utterances, and that Ross’s search ends upon finding a match whereas Kennewick scores the entire context stack. Id. at 10. Patent Owner’s late arguments, to which Petitioner has not had an opportunity to respond, do not undermine Petitioner’s proposed motivations to combine with reasonable expectation of success. See 37 C.F.R. § 42.23(b). Patent Owner’s arguments hinge on its assertion that “expected contexts” are not scored and are dynamic, but the ’160 patent does not define “expected contexts” in this way. See § III.C, supra. Furthermore, we do not agree that Ross’s search necessarily ends upon finding a match or that Kennewick and Ross are otherwise incompatible. See Inst. Dec. 19–22. Thus, we find that Petitioner has demonstrated by a preponderance of the evidence that a POSITA would have been motivated to combine Kennewick and Ross with a reasonable expectation of success to arrive at the claimed invention. 4.” slip op. at 22

    “We secondly conclude a POSITA would have had at least two years of experience designing and/or developing CMP technology per Patent Owner’s formulation, but we reject Patent Owner’s additional contention that this experience must include designing and/or developing pad dressers specifically. The ’270 patent claims are directed to the structure of a pad dresser, not to a method of making a pad dresser. See Ex. 1001, 17:35– 18:38. According to the ’270 patent specification, the claimed pad dresser structure is designed to condition a polishing pad so the pad may be used to attain “high performance levels in aspects such as uniformity of polished wafer, smoothness of the IC circuitry, removal rate for productivity, longevity of consumables for CMP economics, etc.” during a CMP process. Id. at 1:20–24 (Background of the Invention). Thus, the ’270 patent’s invention generally focuses on optimizing a pad dresser structure to achieve desired results in a CMP process, not necessarily on how to manufacture a pad dresser. As such, we reject Petitioner’s POSITA formulation requiring “experience in the field of integrated circuit processing and fabrication techniques” (Pet. 19) as too generic in the context of the ’270 patent’s claimed invention. We also conclude, in view of the ’270 patent disclosures discussed above, that Dr. Tsai’s opinion that ordinary skill requires experience with manufacturing pad dressers (see Ex. 2011 ¶ 28) is too conclusory and lacking in evidentiary support to be persuasive. See Best Med. v. Elekta, 46 F.4th at 1353 (“The patent’s purpose can also be informative.”).” slip op. at 9

    “The Federal Circuit has held: “To offer expert testimony from the perspective of a skilled artisan in a patent case — like for claim construction, validity, or infringement — a witness must at least have ordinary skill in the art.”9 Kyocera Senco Indus. Tools Inc. v. Int’l Trade Commission, 22 F.4th 1369, 1375–77 (Fed. Cir. 2022); see also Osseo Imaging, LLC v. Planmeca USA Inc., 116 F.4th 1335, 1340–41 (Fed. Cir. 2024) (holding that the proffered expert does not need to have acquired the 9 Petitioner cites the Practice Guide’s statements that there is “no requirement of a perfect match between the expert’s experience and the relevant field” and “[a] person may not need to be a person of ordinary skill in the art in order to testify as an expert under Rule 702, but rather must be ‘qualified in the pertinent art.’” Practice Guide 34 (citing SEB v. Montgomery Ward, 594 F.3d at 1373; Sundance v. DeMonte, 550 F.3d at 1363–64). To the extent there is any tension between the Practice Guide (issued in 2019) and the Kyocera holding (issued in 2022), we apply the latter here.” slip op. at 12

    “We determine Dr. Shanfield has sufficient education and experience to qualify as a person of ordinary skill in the art pertaining to the ’270 patent. Dr. Shanfield’s Ph.D. in physics satisfies the educational prerequisite of at least a bachelor’s degree in an engineering related field such as physics. See Ex. 1002 ¶ 2, App. A. Furthermore, his advanced degree (Ph.D. in physics) versus ordinary skill (a bachelor’s degree in an engineering related field) provides considerable leeway when turning to the experiential component for ordinary skill. Nonetheless, Dr. Shanfield also has at least two years of experience with designing and developing CMP technology per the experience prerequisite, as follows. Dr. Shanfield worked at Raytheon Corporation for over 10 years, during which he “worked directly with engineers in the selection, installation, and optimization of several chemo-mechanical polishing systems (CMP), including analysis of operational maintenance and performance monitoring,” and he “directly participated in establishing the required metrology (optical thickness monitoring) for maintaining polishing uniformity standards.” Ex. 1002 ¶ 3 (emphasis added). He later joined Draper Laboratory in 2003, where he currently is the Division Leader of Advanced Hardware Development. See id. ¶ 5. During Dr. Shanfield’s time at Draper, the laboratory “acquired several semiconductor-grade CMP systems for the purpose of fabricating multi-chip modules and for planarization operations in MEMS devices,” and he was “involved in their operation and optimization.” Id. (emphasis added). When asked during a deposition whether he is “an expert in CMP equipment design,” Dr. Shanfield stated he is “very familiar with the design of CMP equipment” because he has “seen many systems” and “installed or supervised the installation of systems.” Ex. 2003, 17:22–19:3. He testified he has “designed apparatus that worked with CMP equipment” although he has not “designed the CMP equipment itself.” Id. at 18:13–19. As an example of being “involved in the manufacture of CMP pad dressers” specifically, Dr. Shanfield stated that during his time at Raytheon, he worked with other professionals “to use the CMP system to process MEMS, M-E-M-S, devices” which “needed a certain kind of planarization process [that] required constant conditioning,” so the team “had to try to fabricate something that would provide conditioning that would last longer.” Id. at 19:4–20:9. Thus, we conclude Dr. Shanfield qualifies as a POSITA pertaining to” slip op. at 13

    “apply the same claim construction standard “used in the federal courts, in other words, the claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. [§] 282(b),” which is articulated in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). 83 Fed. Reg. 51,340, 51,358 (Oct. 11, 2018) (amending 37 C.F.R. § 42.100(b) effective November 13, 2018) (now codified at 37 C.F.R. § 42.100(b) (2019)). Under the Phillips standard, the “words of a claim are generally given their ordinary and customary meaning,” which is “the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention, i.e., as of the effective filing date of the patent application.” Phillips, 415 F.3d at 1312–13. Petitioner proposes constructions for terms: “superabrasive,” “protrusion,” “sharp portion,” and “attitude.” Pet. 20–21. Patent Owner does not propose constructions for any claim term. See generally, PO Resp. We discern constructions of these claim phrases or others are not required for the purposes of this Decision. Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

    “In his deposition testimony, Dr. Tsai testifies that the Sung ’026 patent application publication “intends to make a diamond disk that has all the protrusion[s] with identical heights and with the same orientation.” Ex. 1049, 50:2–4. Dr. Tsai also testified that “[i]n addition, [Sung ’026] also intends to control the depths of penetrating into the pad. For example, if I want to penetrate 10 micron into the pad, then the protrusion height should be at least 10 micron.” Id. at 50:10–13. So, contrary to Dr. Tsai’s Declaration testimony in Ex. 2011 ¶ 69, Dr. Tsai clarifies in his deposition testimony that Sung ’026 intends to combine three distinct aspects or embodiments. He testifies that “first one is that you need to have the same orientation, same shape so you can have the consistency; and No. 2, you would like to have the same height; and No. 3, you would like to control the penetration depths.” Ex. 1049, 51:2–6. Dr. Tsai was then asked “[s]o Sung ’026 is trying to combine all three of those together, correct?” Id. at 51:9– 10. His answer was “[t]hat’s correct, because if you can have a very good control of those, then -- and that time period back then, then you can make a very perfect diamond disk.” Id. at 51:11–13. Based on the evidence as discussed above, we determine that Sung ’026 discloses the elements and limitations in clause 1[C]. In particular, we credit Dr. Shanfield’s testimony (as summarized above) over Dr. Tsai’s declaration testimony, because Dr. Tsai’s deposition testimony essentially agreed with Dr. Shanfield that Sung ’026 discloses all the aspects recited in claim 1 together in a single embodiment.” slip op. at 48

    “Moreover, our general approach for considering challenges to the admissibility of evidence was outlined in Corning Inc. v. DSM IP Assets B.V., IPR2013-00053, Paper 66 at 19 (PTAB May 1, 2014). As stated in Corning, similar to a district court in a bench trial, the Board, sitting as a non-jury tribunal with administrative expertise, is well-positioned to determine and assign appropriate weight to evidence presented. Id. (citing Donnelly Garment Co. v. NLRB, 123 F.2d 215, 224 (8th Cir. 1941) (stating, in the context of reviewing an administrative determination of the National Labor Relations Board based on findings by a Trial Examiner, “We think that experience has demonstrated that in a trial or hearing where no jury is present, more time is ordinarily lost in listening to arguments as to the admissibility of evidence and in considering offers of proof than would be consumed in taking the evidence proffered . . . One who is capable of ruling accurately upon the admissibility of evidence is equally capable of sifting it accurately after it has been received . . . .”)). Moreover, “there is a strong public policy for making all information filed in an administrative proceeding available to the public.” Liberty Mut. Ins. Co. v. Progressive Cas. Ins. Co., CBM2012-00010, Paper 59 at 40 (PTAB February 24, 2014). Rather than excluding evidence that is allegedly hearsay, confusing, misleading, untimely, and/or irrelevant, we will simply not rely on it or give it little or no probative weight, as appropriate, in our analysis. “In an inter partes review, we regard it as the better course to have a complete record of the evidence to facilitate public access, as well as appellate review.” Sony Computer Entm’t Am. LLC v. Game Controller Tech. LLC, IPR2013-00634, Paper 32 at 31 (PTAB Apr. 14, 2015); see also Gnosis S.p.A. v. S. Alabama Med. Sci. Found., IPR2013-00118, Paper 64 at 43 (PTAB June 20, 2014) (citing Donnelly, 123 F.2d at 224 (“If the record on review contains not only all evidence which was clearly admissible, but also all evidence of doubtful admissibility, the court which is called upon to review the case can usually make an end of it, whereas if evidence was excluded which that court regards as having been admissible, a new trial or rehearing cannot be avoided.”)).” slip op. at 32

    “According to Patent Owner, Petitioner’s argument is that “several distinct portions of Sung ’026 purportedly, when viewed together, disclose an embodiment that satisfies the recitation of Claim Limitation [1C].” Id. at 20. Patent Owner asserts, however, that “these individual embodiments of Sung ’026—which it describes in separate portions of the reference as discrete ‘aspects’ of the invention of Sung ’026—cannot not be used collectively to satisfy the anticipation standard.” Id. (citing Net MoneyIN, 545 F.3d at 1371). Simply put, it is Patent Owner’s position that because Sung ’026 fails to disclose these various aspects in a single embodiment as Claim Limitation [1C] recites, Sung ’026 cannot anticipate claim 1. It is Petitioner’s position that Dr. Tsai’s deposition testimony supports Petitioner’s assertions that Sung ’026 anticipates independent claim 1 because the various alleged “individual embodiments” are part of a unified whole that overcome the circumstances discussed in Net MoneyIN. In his deposition testimony, Dr. Tsai testifies that the Sung ’026 patent application publication “intends to make a diamond disk that has all the protrusion[s] with identical heights and with the same orientation.” Ex. 1049, 50:2–4. Dr. Tsai also testified that “[i]n addition, [Sung ’026] also intends to control the depths of penetrating into the pad. For example, if I want to penetrate 10 micron into the pad, then the protrusion height should be at least 10 micron.” Id. at 50:10–13.
