    “We agree with Petitioner that the term “3D slices” has no apparent connection to the phrase “direct volume rendering.” Patent Owner’s argument appears to be that DVR “requires an image of the entire anatomical volume that is neither feature-specific nor segmented, [which] would seemingly require that all inner layers be displayed.” Reply 4; see Sur-reply 6–10 (not disputing Petitioner’s characterization). But, as Petitioner notes, the specification directly undermines this by teaching “display [of] a slice of the 3D data instead of a volume of the 3D data.” See Reply 4 n.2 (quoting Ex. 1001, 5:34–35). In other words, to the extent DVR would depict an image of the entire anatomical volume, displaying 3D slices “instead of a volume of the 3D data” implies the opposite of DVR. Even if “3D slices” somehow implied DVR, Patent Owner’s position is still untenable. Claim 1 does not recite “3D slices.” Instead, claim 1 recites “3D data” and “inner layers.” Ex. 1001, 18:54–65. Patent Owner fails to clarify the relationship between “slices,” “3D data,” and “layers,” and its expert even admits that slices and layers are two different things. See PO Resp. 13; Ex. 1022, 32:7–16 (agreeing that the words “slice” and “layer” are not “synonyms”), cited in Reply 4. We also agree with Petitioner that dependent claim 3 distinguishes slices and layers by reciting “slices of the projected inner layer.” Reply 4 (quoting Ex. 1001, 19:3–10). Thus, even if 3D slices somehow implied DVR, the language of claim 1 does not support limiting the claim this way.” slip op. at 12

  • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner

    “The determination of whether a document was publicly accessible “involves a case-by-case inquiry into the facts and circumstances surrounding the reference’s disclosure to members of the public.” Medtronic, Inc. v. Barry, 891 F.3d 1368, 1380 (Fed. Cir. 2018). For instance, courts routinely rely on the Wayback Machine to determine when a reference was first made available to the public. Valve Corp. v. Ironburg Inventions Ltd., 8 F.4th 1364, 1374 (Fed. Cir. 2021) (“District courts have taken judicial notice of the contents of webpages available through the Wayback Machine ‘as facts that can be accurately and readily determined from sources whose accuracy cannot reasonably be questioned.’”). We disagree with Patent Owner’s argument that “Medivis cannot rely on additional prior art”—Exhibits 1023 and 1024—“that was submitted after its Petition to carry its burden without leave from the Board.” Sur-reply 4. As Patent Owner did not file a motion to exclude these exhibits, we decline Patent Owner’s invitation to disregard them. We also find Petitioner’s Reply argument proper because it directly responds to Patent Owner’s contention that Petitioner did not prove the public accessibility of Amira. See Chamberlain Grp., Inc. v. One World Techs., Inc., 944 F.3d, 919, 925 on issues previously raised.”). Petitioner’s Reply argument appropriately elaborates on the Petition’s contention that Amira was publicly accessible. Patent Owner also does not dispute the substance of Petitioner’s evidence. For example, Patent Owner does not address the substance of Mr. Frank-White’s declaration. We find that this evidence, including Mr. Frank- White’s declaration testimony, persuasively supports the public availability of Amira as of the date shown in the Wayback Machine URL.

    “We agree with Patent Owner that Petitioner’s evidence in Kuntz (Ex. 1026), the Annual Report (Ex. 1028), Masuko (Ex. 1029), and Pfaff (Ex. 1034) is insufficient to show that Xirallic® Sample C was available to the public before the effective filing date of the ’861 patent. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26. Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public. We also agree with Patent Owner that the Technical Data Sheets (Exs. 1005–1010), Certificates of Analysis (Exs. 1011–1017), and Material Safety Data Sheet (Ex. 1025) are insufficient to show that Xirallic® Sample C was available to the public. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26–27. Regardless of how the Technical Data Sheets were used in the Opposition against the European counterpart of the ’861 patent (Exs. 1040, 1041) and during the prosecution of the application from which the ’861 patent issued (Ex. 1003, 102–104), the Technical Data Sheets do not refer to or describe the lot of Xirallic® from which Sample C was taken. Moreover, as noted by Patent Owner, the Technical Data Sheets (Exs. 1005–1010) indicate that they are “preliminary” and Petitioner has not provided any evidence that the Technical Data Sheets were ever issued to the public, as opposed to just issued internally. See PO Resp. 18–19. We also find persuasive Patent Owner’s argument that the Technical Data Sheets are preliminary because other, later-dated technical data sheets (Exs. 2012, 2013) lack the “preliminary” label and list characteristics that are different from those in Exhibits 1005–1010. See PO Resp. 19 (comparing, e.g., Ex. 1009 and Ex. 2013; Ex. 1005 and Ex. 2012).

Cir. 2015); Inwood Labs., Inc. v. Ives Labs., Inc., 456 U.S. 844, 856 (1982)). We have reviewed the witness testimony in the record and, more particularly, Mr. Choi’s deposition answers regarding Petitioner’s purchase of the lot of Xirallic® from which Sample C came. We find that Mr. Choi’s responses cast doubt on the credibility of his declaration testimony, namely with regard to the public availability of Sample C. Mr. Choi represented that he was involved in the purchase of the lot of Xirallic® from which Sample C was taken. Ex. 2011, 48:1–23. Mr. Choi stated that he instructed Petitioner’s marketing team manager to buy the sample from a distributor of Patent Owner’s products located in Europe. Id. at 48:24–49:4. Mr. Choi stated that he has evidence of the transaction, but refused to reveal the name of the company from which Petitioner purportedly purchased the lot of Xirallic® (id. at 49:5–50:3) and refused to produce an email in his possession that would corroborate his testimony regarding Petitioner’s acquisition of the product (id. at 50:8–16, 51:10–23). Mr. Choi represented that he does not remember how much Petitioner paid for Sample B. Id. at 56:4–5. Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

    “Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38

    “a first current through one or more output ports of the at least one output port in a first operating mode,” and “is configured to output a second current capable of starting a vehicle engine through the pair of output terminals in a second operating mode.” Ex. 1001, 8:25–34. Claim 21 has similar first and second operating-mode limitations. Id. at 9:40–46. Patent Owner proposes that “[t]he proper construction for ‘first operating mode’ is ‘an operating mode of the portable backup charger wherein the battery pack is configured to output a first current through one or more output ports of the at least one output port, and outputting a second current capable of starting a vehicle engine through the pair of output terminals is inhibited.’” PO Resp. 25. Similarly, Patent Owner argues “[t]he proper construction for ‘second operating mode’ is ‘an operating mode of the portable backup charger wherein the battery pack is configured to output a second current capable of starting a vehicle engine through the pair of output terminals, and outputting a first current through one or more output ports of the at least one output port is inhibited.’” Id. at 27. Patent Owner asserts that claim differentiation supports its construction because dependent claim 3 recites “a third operating mode for outputting the first current and the second current simultaneously,” and “if the battery pack could output the first current and the second current simultaneously in the first operating mode, then there would be no difference between the claimed first operating mode and the claimed third operating mode.” Id. at 26. We disagree with Patent Owner’s constructions because, as Petitioner explains, they wrongly import current-inhibiting limitations beyond the plain language in the claim. Pet. Reply 1. Nothing in the at-issue language addresses inhibiting current. In addition, the claimed first and third operating modes are still distinct without importing additional limitations because outputting just the first current is sufficient for the first operating mode, but not for the third. In other words, whereas the third operating mode requires simultaneity, the first and second merely permit it. Thus, claim differentiation does not support Patent Owner’s construction. Last, although Patent Owner asserts that its construction “is consistent with the specification,” nothing in the cited passages describes inhibiting current. Prelim. Resp. 26 (citing Ex. 1001, 4:30–33, 5:30–33, 5:58–62). Instead, the specification characterizes the modes solely by what the portable charger “can output,” not what is inhibited. Ex. 1001, 4:30–33, 5:30–33, 5:58–62. Thus, we decline to read the first and second operating modes to require the current-inhibiting features that Patent Owner asserts.” slip op. at 6

In addition, we agree with Petitioner that Chen shows the claimed different current paths even under Patent Owner’s construction. Pet. Reply 8–12.

    “As we explained in our Institution Decision, we disagreed then, and still disagree, “that the second pressure must be detected after the first pressure is detected (or that the third pressure must be detected after the first pressure is detected) simply because the second pressure is greater than the first pressure (and the third pressure is greater than the second pressure).” Dec. 27. As we explained there, “[t]he claimed relative magnitudes of the first, second, and third pressures do not define any temporal relationships regarding the detection of the pressures.” Id. We agree with Petitioner that claim 1 recites quantitative relationships for the pressures, not temporal relationships. Reply 4. For example, claim 1 requires “the second pressure greater than the first pressure” but says nothing about when the second pressure must be greater than the first pressure. A key misconception undergirding Patent Owner’s argument is its statement that “a ‘first pressure’ must first exist before the invention can detect that the ‘second pressure’ is greater.” PO Resp. 27 (emphasis added). The claim does not require detecting that the second pressure is greater than the first pressure. Limitation [1c] simply says, “detect a second pressure on the first input device, the second pressure greater than the first pressure.” In other words, all the detection that this limitation requires is detecting a second pressure. The claim then observes that the second pressure is greater than the first pressure but does not require detecting this. Limitation [1e] similarly detects pressure but not the comparison: “detect a third pressure on the first input device, the third pressure greater than the second pressure.” Thus, it does not follow that “a ‘first pressure’ must first exist before the invention can detect that the ‘second pressure’ is greater.” See id.

Patent Owner’s reliance on non-limiting specification language is also unavailing. E.g., Ex. 1001, 8:38–46 (“can” and “may”), 4:30–44 (“embodiment” and “may”).” slip op. at 13

Patent Owner argues that claim 15 recites a “system comprising” “an input device configured to control one of a plurality of systems,” and hence “the recited plurality of systems are subsystems in addition to the containing system.” Id. We question how this point supports Patent Owner’s proposal because this does not address why each system must “provide[] context for virtual detents.” But regardless, we find it unpersuasive because claim 15’s preamble is not limiting (merely reciting “A system comprising”).

    “(4) Analysis We are persuaded by Petitioner’s argument that during the alignment process in Odachi corresponding to claim 13, there is a “spaced distance between the primary inductive coupler [230] and the secondary inductive receptacle 2” which is “reduced gradually and electromagnetic induction occurs between the coupler to the receptacle when the former coupler comes close to the latter receptacle.” Ex. 1005, 6:1–6. Thus, prior to any contact or precise alignment between the two cores, “an electromotive force is induced in the secondary coil 4 and this induced force is increased with the decrease in the spaced distance.” Id. at 6:6–8. At least in that spaced configuration, the evidence of record suggests that primary coil 31 produces a near-field component of flux into free space (the air space between the coils where there is no intervening core material) that is intercepted by secondary coil 4 to effect resonant inductive coupling, and that secondary coil 4 intercepts and receives the near-field component of flux in free space that is generated by primary coil 31 to effect resonant inductive coupling. See Ex. 1032 ¶¶ 48–52, 55. Thus, we find that Odachi discloses a “transmitting antenna” (coil 31) and a “receiving antenna” (coil 4) under Patent Owner’s proposed construction. We would reach the same finding under Petitioner’s proposed broader construction because the evidence suggests that Odachi’s coils 31 and 4 would have been considered “antennas” under the parties’ uncontested definition of that term, which is “a device that radiates and/or receives radio waves.” See id. ¶¶ 43–47, 53–54; Ex. 1032 ¶ 15 (Dr. Allen agreeing with this definition of “antenna”); Ex. 2001 ¶ 25 (Dr. Horenstein agreeing with this definition of “antenna”)). In addition, Petitioner persuasively shows that the free space between Odachi’s coils in the spaced configuration includes the “near-field region,” which includes the induction field around primary coil 31. See Ex. 2006, 498; Ex. 1045, 5:4–7; Ex. 1032 ¶¶ 53–54). Dr. Horenstein’s testimony does not contradict this. Although he points out that there are separate terms for inductive, near, and far fields, he also acknowledges that “[t]he region of space closer to the antenna than the far field is the near-field region.” Ex. 2010 ¶ 37 (citing Ex. 2006, 275).8” slip op. at 22

The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional.

    “In order to determine whether an invention would have been obvious at the time the application was filed, we consider the level of ordinary skill in the pertinent art. Graham, 383 U.S. at 17. In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (quotation omitted). Petitioner contends a person of ordinary skill in the art “would have possessed at least a four-year degree in electrical engineering, chemical engineering, physics, or material science, or a closely related field, and at least two years of experience in semiconductor device design or fabrication, including the processing of semiconductor materials, analysis of device operation, or the development of new device topologies.” Pet. 5–6. Petitioner contends “[a]dditional education could substitute for professional experience and vice versa.” Id. at 6. Patent Owner contends that a person of ordinary skill in the art would have had “at least a four-year degree in electrical engineering, physics, material science, or a closely related field, and three years of professional work experience in the epitaxial growth, design, and fabrication of semiconductor electronic devices, including those of GaN.” PO Resp. 7 (citing Ex. 2009 ¶ 82).

    “compensated GaN layer above the barrier layer, and a gate contact above the compensated GaN layer.” Ex. 1001, 5:12–18. Petitioner contends the term “compensated” indicates that the step of compensating the GaN layer has already occurred, such that the term “compensated GaN layer” should be construed as a “‘[d]oped GaN layer formed with a step to passivate its impurities’ which is a ‘product-by-process’ limitation.”5 Pet. 12–14. And, because compensation with hydrogen was the “critical step” distinguishing the claims from the prior art, and because hydrogenation in as-grown III-nitride materials had been well known for over a decade by 2009, Petitioner contends “compensated” “cannot be interpreted as mere hydrogen presence in as-grown material, a well-known property of doped GaN.” Id. at 15. Patent Owner contends “compensated GaN material” should be construed as “a semiconductor GaN gate material in which one type of impurity (for example, donor) cancels the electrical effects of the other type of impurity (for example, acceptor).” PO Resp. 11 (citing Ex. 2009 ¶ 92) (emphasis added). Patent Owner contends this construction is consistent with the IEEE dictionary, which defines “compensated semiconductor” as 5 Given that product-by-process steps in a device claim are not entitled to patentable weight, Petitioner contends “the prior art only need show a material with passivated impurities to show unpatentability, not the step to achieve it.” Pet. 15–16. “[a] semiconductor in which one type of impurity or imperfection (for example, donor) partially cancels the electric effects of the other type of impurity or imperfection (for example, acceptor).” PO Resp. 14 (quoting Ex. 2004). Patent Owner contends its construction is also consistent with the written description of the ’294 patent, which explains that a compensated GaN material is part of the gate and includes a p-type impurity that imparts an electrical effect (i.e., conductivity), as well as a second impurity, e.g., hydrogen, that partially cancels the electrical effect of the p-type impurity, rendering the layer semi-insulating. Id. at 14–15 (citing Ex. 1001, 3:10–13, 3:43–45). On this record, we construe “compensated GaN layer” as “a GaN layer in which one type of impurity (for example, donor) partially cancels the electric effects of the other type of impurity (for example, acceptor).” This is consistent with the disclosures of the ’294 patent, the IEEE dictionary definition, and the construction ultimately adopted by the ITC. Ex. 2004, 3; Ex. 1049, 16–17 (ITC construing “compensated GaN layer” to mean “a GaN layer in which one type of impurity partially cancels the electrical effects of another type of impurity”); Ex. 1001, 3:43–45 (explaining that the compensated GaN layer of the ’294 patent is formed through the “passivation of a p-type impurity using hydrogen”).

    “There are two exceptions to the general rule that we apply the ordinary and customary meaning of a claim term: (1) when a patentee sets out a definition and acts as his own lexicographer, or (2) when the patentee disavows the full scope of a claim term either in the specification or during prosecution. See Thorner, 669 F.3d at 1365. The standards for lexicography and disclaimer, however, are “exacting.” Id. at 1366. There is no argument that the patentees acted as their own lexicographer to redefine the term “compensated GaN layer.” With respect to disavowal, a “patentee may demonstrate intent to deviate from the ordinary and accustomed meaning of a claim term by including in the specification expressions of manifest exclusion or restriction, representing a clear disavowal of claim scope.” Thorner, 669 F.3d at 1366 (quoting Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1325 (Fed. Cir. 2002)). As noted by Patent Owner, the title of the ’294 patent is, in part, “Compensated Gate MISFET” and much of the discussion of the ’294 patent is of a compensated GaN layer that is directly below the gate contact and above a barrier layer and operates in conjunction with the gate contact to control the on/off state of the transistor. PO Resp. 12–14. We are presented with insufficient argument or evidence to conclude, however, that these disclosures rise to the level of a disclaimer. For example, although the title of the ’294 patent is directed to a “Compensated Gate MISFET,” claim 1 is more broadly directed to “[a] column III Nitride transistor.” Ex. 1001, 5:12, code (54). Nor are we directed to an expression or statement of manifest exclusion in the ’294 patent that would serve to disclaim any “compensated GaN layer” that is not directly below the gate and/or that does not function in concert with the gate electrode to control the on/off state of the transistor. See Thorner, 669 F.3d at 1366. With respect to the stated goals of the invention, as noted by Patent Owner, one of the primary purposes of the compensated GaN layer of the ’294 patent is to reduce gate leakage and gate capacitance. Ex. 1001, 2:13– 19, 3:18–21 (“[U]sing a compensated semiconductor layer 38 leads to low gate leakage during device operation.”). We cannot use the goals of the invention, however, to rewrite the claims or insert terms that are not present. See Thorner, 669 F.3d at 1366. Moreover, the prior art of record indicates that a compensated GaN layer that is below the gate contact and above a barrier layer, but not part of the active gate structure, may also “decrease the leakage current between the gate and the drain.” Ex. 1006 ¶¶ 44 (“Even when a positive bias of 5 V or higher is applied to the gate electrode, no significant gate-leakage current is observed.”), 61. As such, evidence of record suggests that a person of ordinary skill in the art would have understood that one of the primary goals disclosed in the ’294 patent is achieved regardless of whether the compensated GaN layer is part of the gate, or simply in close vicinity to the gate. In view of the foregoing, we are not persuaded that the written description of the ’294 patent indicates that the “compensated GaN layer” must be part of the gate structure.” slip op. at 17

    “To be probative, Patent Owner must prove there is a nexus between the presented evidence and the merits of the claimed invention. See Demaco Corp. v. F. Von Langsdorff Licensing Ltd., 851 F.2d 1387, 1392 (Fed. Cir. 1988). A rebuttable presumption of nexus applies when the “patentee shows that the asserted evidence is tied to a specific product and that the product ‘is the invention disclosed and claimed.’” Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (quoting Demaco, 851 F.2d at 1392). “That is, presuming nexus is appropriate ‘when the patentee shows that the asserted objective evidence is tied to a specific product and that product embodies the claimed features, and is coextensive with them.’” Id. (quoting Polaris Indus., Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1072 (Fed. Cir. 2018)). If the praise is not limited to the features of the claimed invention, the patent owner may still prove nexus “by showing that the evidence of secondary considerations is the ‘direct result of the unique characteristics of the claimed invention.’” Id. at 1373–74 (quoting In re Huang, 100 F.3d 135, 140 (Fed. Cir. 1996)). Patent Owner contends that the compensated gate of the ’294 patent “was a breakthrough invention and resulted in the first commercially viable enhancement-mode GaN transistor.” PO Resp. 60 (citing Ex. 2009 ¶¶ 192– 193, 197; Ex. 2021). Patent Owner further contends that this achievement required the counter-intuitive use of a compensated gate material in the gate structure, and represented “a technological leap that laid the foundation for viable enhancement-mode GaN transistors.” Id. at 61–62. For this achievement, Patent Owner contends the inventor, Dr. Alex Lidow, received the 2015 SEMI Award. Id. at 60 (citing Ex. 2021). Upon review of Patent Owner’s evidence and the parties’ arguments, we find that Patent Owner’s objective indicia evidence is entitled to little, if any, weight. The evidence of praise relied upon by Patent Owner is not clearly linked to the claimed invention or any particular product having each of the claimed features of the ’294 patent. Ex. 2021. For example, the 2015 SEMI award was provided to Dr. Lidow “for commercialization of GaN power devices.” Id. An article explaining the award indicates that “high cost” previously “limited [the] commercial success” of GaN technologies, but Dr. Lidow was able to overcome these issues, “from resolving packaging limitations to establishing a low-cost supply chain,” “through persistence.” Id. This praise is not demonstrably linked to the claimed invention or any particular device, and does not mention the use of a compensated gate, or any other relevant feature recited in the claims. In view of the foregoing, we determine that Patent Owner’s objective evidence of non-obviousness is entitled to little, if any, weight.” slip op. at 20

    “After considering the record as a whole, we determine that Petitioner has adequately demonstrated that the Office erred in a manner material to the patentability of challenged claims. As we explain in Section III(G), infra, Petitioner’s challenges to the ’227 patent appear strong based on the current record, and Patent Owner’s present arguments to the contrary are weak. Given the strength of Petitioner’s challenges on the present record, this is not a situation where we would say that “reasonable minds can disagree regarding the purported treatment of the art,” and we therefore determine that the Examiner erred by not considering the art in substantially the combination Petitioner proposes. Where Patent Owner states that “evidence that the Examiner did not consider these references in combination” is lacking (PO Sur-Reply 5), we disagree. If the Examiner considered these references in combination, the Examiner would have, given the apparent strength of Petitioner’s position on the merits on this record, issued a rejection. The lack of a rejection based on the combination proposed in the Petition provides some evidence that the Examiner did not consider these references in combination (because the lack of such a rejection raises the likelihood that the Examiner did not make such a consideration). 3.

    “IV. CONCLUSION For the reasons above, we determine that the information presented in the Petition establishes that there is a reasonable likelihood that Petitioner would prevail with respect to challenged claims 1–30 of the ’602 patent. At this juncture in the proceeding, we have not made a final determination with respect to the patentability of the challenged claims, or with respect to claim construction. V. ORDER For the foregoing reasons, it is ORDERED that pursuant to 35 U.S.C. § 314(a), an inter partes review of claims 1–30 of the ’602 patent is hereby instituted with respect to all grounds of unpatentability set forth in the Petition; and” slip op. at 36

    “efficiency and integrity of the system are best served by denying or instituting review.” Fintiv at 6. Here, Fintiv factors one and five are neutral, factors two and three favor discretionary denial, factor four strongly weighs against discretionary denial, and favor six weighs against discretionary denial. The integrity of the system will benefit from institution because of the strong merits the Petition presents (factor six), and the ITC Investigation will not resolve these merits (factor four). This outweighs any potential inefficiency as indicated by factors two and three. We further note that any inefficiency in resolving the grounds the Petition presents is mitigated by the stay of the district court action (factor one). We, thus, decline to exercise discretionary denial under 35 U.S.C. § 314(a).” slip op. at 17

    “After considering the record as a whole, we determine that Petitioner has adequately demonstrated that the Office erred in a manner material to the patentability of challenged claims. As we explain in Section III(G), infra, Petitioner’s challenges to the ’602 patent appear strong based on the current record, and Patent Owner’s present arguments to the contrary are weak. Given the strength of Petitioner’s challenges on the present record, this is not a situation where we would say that “reasonable minds can disagree regarding the purported treatment of the art,” and we therefore determine that the Examiner erred by not considering the art in substantially the combination Petitioner proposes. Where Patent Owner states that “evidence that the Examiner did not consider these references in combination” is lacking (PO Sur-Reply 5), we disagree. If the Examiner considered these references in combination, the Examiner would have, given the apparent strength of Petitioner’s position on the merits on this record, issued a rejection. The lack of a rejection based on the combination proposed in the Petition provides some evidence that the Examiner did not consider these references in combination (because the lack of such a rejection raises the likelihood that the Examiner did not make such a consideration). 3. Conclusion Because Petitioner adequately made a showing of material error, we decline to exercise discretion not to institute inter partes review under 35 U.S.C. § 325(d).
