“In particular, we agree with Patent Owner that “[n]ot only does Cantor not teach contacting a ‘tissue sample’ with beads, but Cantor comes nowhere close to suggesting that its beads could be contacted with a tissue sample to identify spatial location.” Prelim. Resp. 50. Here, we are persuaded by the testimony of Dr. Cantor, sole inventor of Cantor (Ex. 2002 ¶ 29), that Cantor’s nucleic acid samples are made in bulk from the extraction of nucleic acids from biological material and mixed together “to create the sample nucleic acid prior to mixing that with the solid phase nucleic acids to capture molecule(s) from the sample nucleic acid.” Id. at ¶ 17. More specifically, “nucleic acids are extracted from the different types of cells within a tissue sample without preserving their spatial distribution.” Id. at ¶ 19. Thus, these types of “bulk-analysis techniques provide no information about spatial location of biological molecules in tissue samples.” Id. at ¶ 17. While we recognize that Cantor discloses “providing the beads according to an (X,Y) array” (Pet. 39, citing to Dr. Puglisi, Ex. 1100 ¶¶ 65– 66), this disclosure makes no mention of using this array to map where the nucleic acids of Cantor came from relative to the original sample, let alone when that original sample is a tissue. See e.g. Ex. 1031, 17. The only mentions of “tissue” made in Cantor are in reference to where the sample may be obtained, for example, “[t]he biological sample can be in any form, including without limitation a solid material such as a tissue.” Id. at 6. Cantor provides no teaching, however, regarding how to use a tissue sample with the probes and methods described in Cantor to identify where the target nucleic acids of Cantor were spatially located within the tissue sample itself. Incidental to the parties’ dispute is whether Petitioner’s reliance on and characterization of Cantor’s use of the terms “sample” and “nucleic acid sample” as equivalent in meaning to “tissue sample” recited in the challenged claims is persuasive. Pet. 21 (citing Ex. 1031, 6). Here, we note that Cantor discloses that “[s]ample nucleic acid may be derived from one or more samples or sources.” Ex. 1031, 5; Ex. 2002 ¶¶ 35, 149. Cantor refers to “sample” as the thing that contains the sample nucleic acid. Ex. 1031, 5. For example, Cantor discloses that “[a] sample may be collected from an organism.” Ex. 1031, 6; Ex. 2002 ¶ 42. When a “sample” comes from a living (or formerly living) source, Cantor refers to that sample as a “biological sample,” which can “be in any form, including without limitation a solid material such as a tissue, cells, a cell pellet, a cell extract, or a biopsy, or a biological fluid . . . .” Id. Those samples, however, are further processed in bulk to obtain the nucleic acid sample. For example, Cantor discloses that the “sample nucleic acid may be a result of nucleic acid purification or isolation and/or amplification of nucleic acid molecules from the sample.” Ex. 1031, 7; see also id. at 54 (The “sample nucleic acid” is derived from a sample or source “by any means commonly known in the art, including but not limited to cell lysis procedures using chemical, physical or electrolytic lysis methods.”); Ex. 2002 ¶ 39. In view of the above, we are not persuaded by Petitioner’s attempts to characterize Cantor’s “nucleic acid sample” as synonymous to “tissue sample” recited in the challenged claims. Rather, we agree with Dr. Cantor that “[a] tissue is simply the source of the sample nucleic acid used in [Cantor’s] methods”—it is not the sample nucleic acid itself. Ex. 2002 ¶¶ 36, 150. Petitioner does not direct us to any persuasive evidence to the contrary.” slip op. at 21

“We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. 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. Given Dr. Schubert’s extensive relevant education and experience, Petitioner does not persuasively explain why Dr. Shealy’s testimony on any specific topic, or his testimony in general, should be given more weight than Dr. Schubert’s.” slip op. at 16

“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.

“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”). For the reasons set forth below, however, we decline to construe “compensated GaN layer” as a product-by-process claim term (as asserted by Petitioner), or to limit the compensated GaN layer to a gate material (as asserted by Patent Owner).” slip op. at 11
- Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner
“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

Here, the challenge claims recite two types of functional limitations. First, independent claim 10 requires the coformer to have a second chemical functionality, which is defined as being complementary to the first chemical functionality via non-covalent hydrogen bonding. That is, the co-former’s second chemical functionality must be complementary to either a carboxamide, carbonyl, or amine functionality of an API via non-covalent hydrogen bonding.

“to move forwardly and rearwardly relative to the frame. Pet. 33–38. For example, paragraph 20, as cited by Petitioner, discloses that the rollers “are movably suspended in the frame in vertical direction, wherein the suspension of said roll or rollers is arranged to convert relative horizontal movements of the roll or rollers into vertical movements thereby compensating and/or attenuating said horizontal movements by gravity.” Ex. 1004 ¶20 (cited at Pet. 34). Further, Zwinkels attributes the forward and rearward movement to the use of the bicycle by the person exercising on it. See Ex. 1004 ¶27 (describing the “horizontal movements induced by the accelerations and decelerations of the training cyclist”) (cited at Pet. 35). Petitioner also cites multiple figures that illustrate forward and rearward movement. Pet. 35–37 (reproducing Ex. 1004, Figs. 3, 5, and 6). There is a reasonable likelihood Zwinkels teaches “wherein the movable interconnection of the upper member with the lower member is configured to enable the upper member to move forwardly and rearwardly in the fore-aft direction relative to the lower member in response to fore-aft forces that are transferred to the upper member from the item of exercise equipment in response to use of the item of exercise equipment,” as recited in claim 1. e) “wherein the movable interconnection of the upper member with the lower member is further configured to provide upward and downward movement of the upper member relative to the support surface during movement of the upper member forwardly and rearwardly in the fore-aft direction relative to the lower member.” Petitioner argues that Zwinkels’s pendulum arms 6 enable the rollers to move upward and downward relative to the frame while the rollers are also moving forwardly and rearwardly relative to the frame. Pet. 39–42. For example, paragraph 24, as cited by Petitioner, discloses that the pendulum arms connecting the rollers at fixed pivoting points on the frame “provides an easy and effective solution for absorbing and attenuating horizontal movements by converting these horizontal movements to vertical movements.” Ex. 1004 ¶24 (cited at Pet. 39). Petitioner also reproduces Figures 5 and 6, which illustrate the displacement of rollers in both the vertical and horizontal directions. Pet. 40 (citing Ex. 1004, Figs. 5–6). Figure 5 is reproduced below. Figure 5, reproduced above, “shows the embodiment in which there are two rollers 4 for the bicycle back wheel.” Ex. 1004 ¶34. Figure 5 shows two configurations of the embodiment on left and right sides. Ex. 1004 ¶34, Fig. 5. The configuration “at the left of FIG. 5 shows the pendulum arms 6 in a resting position, whereas the [configuration] on the right shows the pendulum arms 6 after they have due to the connecting link 7 concertedly moved to the right due to a force FH, causing that the rollers 4 have moved vertically upwards.” Ex. 1004 ¶34. There is a reasonable likelihood Zwinkels teaches “wherein the movable interconnection of the upper member with the lower member is further configured to provide upward and downward movement of the upper member relative to the support surface during movement of the upper member forwardly and rearwardly in the fore-aft direction relative to the lower member,” as recited in claim 1. f) “wherein the upper member is oriented parallel to the support surface plane during movement of the upper member relative to the lower member in the fore-aft direction and during upward and downward movement of the upper member relative to the support surface” Petitioner argues that Zwinkels’s rollers are oriented parallel to the ground or floor at all times. Pet. 42–44. Petitioner argues that this is clearly shown in Figure 5, which we reproduced in the immediate section above. See Pet. 43 (citing and annotating Ex. 1004, Fig. 5). We agree.

“We find that Holmberg expressly contemplates using its wall box within multi-dwelling units, notes that multi-dwelling wall boxes in the prior art were “typically provided” on every floor, and discloses that the multi-dwelling wall boxes would contain optical couplings for each resident on a given floor. Ex. 1004 ¶¶ 7, 34; Pet. Reply 8–10. In view of these disclosures, we credit the testimony of Dr. Kiaei that one of ordinary skill in the art would have sought to use Holmberg’s wall box in multi-dwelling units and would have seen a need to access the area behind spice tray 230 to connect and disconnect subscribers. Ex. 1003 ¶ 92; Ex. 1033 ¶¶ 7–8. Moreover, even if Holmberg were limited to mid-span locations and distributing drop cables, as opposed to distribution cables for individual subscribers, as asserted by Patent Owner, Patent Owner does not dispute that a technician would still need periodic access to the area behind splice tray 230 in these mid-span devices. Tr. 38:3–39:1 (counsel agreeing that one would need to access the area behind splice tray 230 in Holmberg, albeit in “rare occasions”); Ex. 1003 ¶¶ 90–92; Ex. 1033 ¶¶ 7–8. Thus, whether used in the manner contemplated by Petitioner or Patent Owner, Petitioner persuasively demonstrates that access to the space behind splice tray 230 in Holmberg would be necessary. With access behind splice tray 230 required, Petitioner persuasively demonstrates that one of ordinary skill in the art would have seen a benefit to replacing Holmberg’s fasteners or screws with a hinged connection, such as that disclosed in Battey, to allow easier access to the area behind the splice tray. Pet. 41 (citing Ex. 1005 ¶ 39 (disclosing that a rotatable splice tray or shelf would “provide[] full and convenient access to the splice tray”)). First, Petitioner and Dr. Kiaei persuasively demonstrate that once the fibers of Holmberg are routed from behind splice tray 230 and the distribution cables spooled on this tray, a technician could not reasonably access fiber optic cables stored behind splice tray 230 without releasing or opening splice tray 230. Pet. Reply 14–15 (citing Ex. 1023, 60:20–61:15); Ex. 1033 ¶¶ 31–32.

“through [1e]. Pet. 28–30. Petitioner further relies on “Racz as modified in view of Fitz and Lee,” with respect to elements [1e] through [1h]. See generally, id. at 30–47. Supported by the testimony of Dr. Tucker, Petitioner contends that one of ordinary skill in the art would have been motivated to combine the teachings of Racz, Fitz, and Lee with a reasonable expectation of success of arriving at the claimed invention. Id. at 1–6, 21–27; Ex. 1034 ¶¶ 132–149. In short, Petitioner contends that “[m]ost of the recited RF needle features—including an elongate cannula, a removable RF probe, a conductive tip, and a monopolar configuration—are conventional features disclosed in . . . Racz,” whereas Fitz discloses that a single-tip device, such as disclosed in Racz, “would produce limited ablation volumes and would have motivated a POSA to solve this problem by adding deployable filaments,” as recited in claim elements [1e] and [1f]. Id. at 4–5, 21–22. In addition to its reliance on the multiple electrode tips disclosed in Fitz, Petitioner contends that Lee would have “motivate[ed] a POSA to implement deployable filaments on the tip of Racz’s device using channels within the cannula,” and “also shows how the filaments can extend outwardly around the needle’s tip to advantageously expand and control the ablation volume.” Id. at 5–6. Accordingly, Petitioner contends, one of ordinary skill in the art “would have found it obvious to modify Racz’s device to include the well-known deployable filaments described in Fitz and Lee,” and would have implemented this combination as “a matter of routine engineering.” Id. at 6, 27.” slip op. at 20
