“That specific claim language of association indicates a relationship between “the block” and the first spatial motion vector prediction candidate, that is more than how every single prediction candidate broadly may be regarded in general as related to the current block being processed, the block for which a motion vector prediction list is being generated. The modifier “associated with the first spatial motion vector prediction candidate” clearly modifies “the block” at issue here and cannot be discarded or ignored. Further, if “the block” refers to the block recited in limitation [9a], i.e., the current block being processed, then the modifying phrase “associated with the first spatial motion vector prediction candidate” would be superfluous and have no meaning, because “the block,” without the modifying phrase, would already derive its antecedent basis from “a block of pixels” recited in limitation [9a]. We decline to adopt a construction that reads out “associated with the first spatial motion vector prediction candidate.” Construing the claim according to what the claim language actually states, without excluding any part of the claim language recited, is more appropriate.” slip op. at 18

“particular teachings sought to be combined. Rather, it appears, according to Petitioner, anything in Nakamura properly can be combined with anything in WD4 simply because Nakamura is a proposal for the next draft version of new standard H.265, i.e., version 4, and WD4 is the resulting draft version 4 of H.265 after all the proposals had been considered. Pet. 65–66. Petitioner’s reasoning is flawed and based on mere speculation. Nakamura is not a proposal to revise or modify WD4. WD4 did not yet exist at the time the Nakamura proposal was made. Even if some suggestions of Nakamura made it into WD4, as Petitioner asserts (Pet. 65), i.e., spatial merge candidate positions unification, that does not mean one of ordinary skill in the art would have had reason to combine other teachings of Nakamura with particular disclosures of WD4. Even assuming Nakamura and WD4 have striking similarities in some way and also a common purpose to some general extent, that still does not mean everything in one is combinable with everything in the other, without specific consideration and discussion of what are proposed to be combined and in what manner. g.

“We must grant or deny institution on both of Petitioner’s grounds. See 37 C.F.R. § 42.108(a). Petitioner has made a sufficient showing based on Rusert and Zheng for the Board to institute review, but not Nakamura and WD4. Here, § 325(d) is not sufficiently implicated that its statutory purpose would be undermined. Rather, the benefits of holding a trial to resolve the Rusert-Zheng ground for which Petitioner has shown a likelihood of prevailing outweigh any theoretical burden of addressing the weaker Nakamura-WD4 ground, to the extent that the Examiner considered Nakamura and WD4.

“At this stage, we agree with Petitioner’s argument. See id. Specifically, we preliminarily construe “dynamic processing mechanism” as “a mechanism for processing data in real-time or near real-time.” See Section II.B.2 supra. And according to Foster, Streams analyzes and acts upon data “with low latency in close to or in real time.” Ex. 1004, 56–57, quoted in Pet. 25. Thus, Petitioner has shown that Streams is a “dynamic processing mechanism.” Pet. 24–25. As for the mechanism’s processing element, we disagree with Patent Owner’s proposed construction for “processing element” (see Section II.B.1. (Prelim. Resp. 33–35). For example, Patent Owner argues that Foster does not disclose a processing element that carries out processing (Prelim. Resp. 33) or that includes code or another computational element (id. at 34). But the claimed processing element is not limited in this way under the construction adopted in this decision.

Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field.

“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
- Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for petitioner
“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

We agree that a person of ordinary skill in the art would have some experience in internet advertising, although we fail to see why one year would not be enough to familiarize sufficiently a computer scientist and/or programmer with the types of problems encountered in the art or prior art solutions to those problems.

“For purpose of institution, we preliminarily determine that claim 1 requires a sequence-level parameter. The claims themselves provide “substantial guidance” regarding the meaning of claim language. Phillips v. AWH Corp., 415 F.3d 1303, 1314 (Fed. Cir. 2005) (en banc). Here, claim 1 recites that the level is for encoding a “sequence.” Ex. 1001, 25:56–60. Claim 1 expressly recites that “the digital video sequence compris[es] a number of frames.” Id. at 25:43–44. In this way, claim 1 defines a sequence to exclude a single picture. This reading is consistent with the specification’s focus on a sequence-level solution. According to the ’148 patent, “The present invention improves prior art solutions for indicating QP related information by introducing a sequence level QP” (SQP). Id. at 11:25–27 (emphasis added). Indeed, Petitioner acknowledges that the SQP is the purported improvement. See Pet. 5. Patent Owner agrees. See, e.g., Prelim. Resp. 8–9, 25–26. Claims are not normally interpreted “in a way that excludes embodiments disclosed in the specification.” Oatey Co. v. IPS Corp., 514 F.3d 1271, 1276 (Fed. Cir. 2008). A trial could produce additional evidence that may support a determination in the Final Written Decision that defining a picture-by-picture quantization level is somehow “for use in encoding of the digital video sequence.” But, at this stage, the parties have given us little reason to adopt such a construction. There is no dispute that H.263 signals PQUANT at the Picture layer. Pet. 51; Prelim. Resp. 25. Indeed, the basis for Petitioner’s challenge is that PQUANT defines the quantizer for a picture and is updated for GOBs or macroblocks within the picture. Pet. 53. We disagree with the interpretation used in Petitioner’s challenge: a picture-layer quantization parameter falls within the scope of the claim. Id. at 51. Rather, for the reasons discussed above, we preliminarily determine that the claims require a sequence-level parameter. And Petitioner has not sufficiently explained why PQUANT is a sequence-level parameter. Thus, we cannot conclude that Petitioner has shown a reasonable likelihood of prevailing in its challenge to claim 1 with respect to H.263. See id.; Prelim. Resp. 25.” slip op. at 19
