      “Patent Owner asserts that the preamble of independent claim 1, 16, and 20 reciting “a deodorant stick” is limiting” as it provides antecedent basis for the recitation of “said deodorant stick being free of an aluminum salt” for each independent claim. PO Resp. 7–10. Patent Owner also points to dependent claims 6–9 as relying on the preamble reciting “a deodorant stick” as antecedent basis for claim elements. Id. at 9. We agree. Petitioner does not provide argument to the contrary. See, e.g., Pet. 19 (arguing that Lesniak discloses a deodorant stick in the form of an antiperspirant stick). We determine that no express construction of any claim term is necessary to determine whether to institute inter partes review. Nidec Motor Corp. v.

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “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). Upon review of the evidence of record and the parties’ arguments, we adopt Petitioner’s definition of the person of ordinary skill in the art as it is consistent with the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (holding that the prior art itself can reflect the appropriate level of ordinary skill in the art). We note, however, that the conclusions reached in this Decision would be the same under either proposed definition of the ordinarily skilled artisan. See Ex. 2009 ¶ 83 (Dr. Schubert testifying that his opinions would be the same under either proposed definition); Ex. 1033 ¶ 9 (Dr. Shealy testifying that the differences in proposed definitions of the ordinarily skilled artisan “would not change the outcome of the invalidity analysis in any material manner”); PO Resp. 7; Pet.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

      “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

      “A claim construction that excludes a particular element is viewed as a “negative limitation.” Ethicon LLC v. Intuitive Surgical, Inc., 847 Fed. App’x 901, 907 (Fed. Cir. Mar. 15, 2021). “[S]uch exclusions must find support either in ‘the words of the claim’ or through an ‘express disclaimer or independent lexicography in the written description that would justify adding that negative limitation.’” Id. (citing Omega Eng’g, Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed. Cir. 2003); CCS Fitness, Inc. v. Brunswick Corp., 288 F.3d 1359, 1366–67 (Fed.

(citing Thorner, 669 F.3d at 1365). Similarly, disclaimer or disavowal requires that the specification or prosecution history demonstrate that the invention does not include a particular feature. Id. Here, we find no claim language, lexicography, or disclaimer in the ’142 Patent or its file history that would support defining a “hot-hard calender” as requiring that only one of the two rollers be heated to an elevated temperature.” slip op. at 12

      “a contact surface of said thermo-roller is heated to an elevated temperature of at least 250°F.” Petitioner shows persuasively that the temperature limitation is taught by the combination of Fugitt and Papermaking. Pet. 32–34. Fugitt discloses that “[t]he rolls of the calender may be steam heated.” Ex. 1004 ¶ 26. In a section titled “Heated Rolls,” Papermaking discloses that “Steam can be used up to 170°C [338°F] surface temperature.” Ex. 1010, 95, 98. Petitioner is thus correct that, “[w]hile Fugitt teaches that a hot calender may be steam heated, Papermaking clarifies that one of ordinary skill in the art would understand that steam heated thermo-rollers may reach up to 338°F.” Pet. 36. Based on these disclosures, we are persuaded by Mr. Zotterman’s testimony that it would have been “obvious to heat the thermo-roller of Fugitt to at least 250°F.” Ex. 1003 ¶ 159. combine Fugitt and Papermaking because of Papermaking’s status as a “trusted handbook[],” because both references disclose a method of manufacturing a paperboard structure with hot calendering,” and “because of the known advantages of heated rollers.” Pet. 36–37; Ex. 1003 ¶¶ 157, 159, 162. Petitioner’s contention is supported by Papermaking’s disclosures that, for cartonboard, “[p]recalendering is used before the coater to reduce roughness and porosity” and “[h]igh thermo roll temperatures (in some cases over 200°C) result in bulk savings because of the temperature gradient.” Ex. 1005, 80–82; see also Pet. 38; Ex. 1003 ¶ 164 (citing these disclosures). Papermaking’s disclosed range of “up to 170°C [338°F]” for steam- heated rolls (Ex. 1010, 98), overlaps the claimed range of “at least 250°F.” Patent Owner agrees. Tr. 27:11–13. “If the relevant comparison between a disputed claim limitation and the prior art pertains to a range of overlapping values, ‘. . . even a slight overlap in range establishes a prima facie case of obviousness.’” Genentech, Inc. v. Hospira, Inc., 946 F.3d 1333, 1341 (Fed. Cir. 2020) (citing In re Peterson, 315 F.3d 1325, 1329 (Fed.

      “second German priority application do not disclose every limitation of independent claims 1 and 7 of the ’430 patent. Figure 1 does not depict a barcode under the flange, but rather the use of raised areas on the side of the capsule that act as an identifier. Ex. 1047, Fig. 1. Figure 2, coupled with its associated description, might suggest that the barcode could be on the portion of the base element facing away from the membrane,9 but this figure does not disclose many of the other elements of the claim, including holding arms, a drop box, annular convexity and concavity, and a pump to supply water to the single-serve capsule. Pet. 41; Ex. 1047, 9:21–24, Fig. 2. We also determine that Patent Owner does not sufficiently demonstrate that Figures 16–18 of the second German priority application provide adequate disclosures showing that the inventors were in possession 9 We question whether the second German priority application supports placing a barcode under the flange. The application states that the barcode could “be provided on that side of the peripheral region of the basic element which is directed away from the membrane.” Ex. 1047, 9:21–24. This statement is rather ambiguous as to where the “peripheral region” is that is “directed away from the membrane.” The text goes on to explain, however, that “[t]his barcode,” i.e., the barcode that is “directed away from the membrane,” “is read by a detector 13,” which in Figure 2 is oriented to read a barcode on the top surface of the flange. Id. at 9:25–26, Fig. 2. This suggests that the barcode is not on the bottom side of the flange and that arrow 15 is pointing to the outer portion of the peripheral region that is not covered by the membrane, and not necessarily the bottom of the flange. First, the second German priority application describes the use of “an identifier” that is read by a “sensor/detection means” and then compared to a stored identifier. Ex. 1047, 2:29–31. In Figure 2 the identifier may be a barcode and the detection means is detector 13. Id. at 9:11–26. In Figures 16–18, however, element 2.4.2 is not an identifier, but rather a “a form-fitting and/or friction-fitting means and/or a detection means.” Id. at 12:22– 24 (emphasis added). As such, it is unclear how this disclosure would demonstrate possession of the disputed claim limitation, when combined with the other limitations of claims 1 and 7 as a whole. Second, it is not evident that the toothed rings of Figures 16–18 are on the underside of the flange, as asserted by Patent Owner. Prelim. Resp. 42 (asserting that a barcode “could be located on the bottom side of the flange instead of the toothed ring”); Prelim. Sur-reply 4. The second German priority application states that the “form-fitting and/or friction-fitting means and/or detection means 2.4.2” is located in the “outer region” of the peripheral region 2.4. Ex. 1047, 12:22–24. We are directed to no evidence that this “outer region” is on the bottom of the flange, and Figures 16–18 each appear to depict means 2.4.2 on, or forming, the outer circumference of the flange.11 Id. at Figs. 16–18, 6:8–11 (noting that the toothed ring is provided “on the outer circumference of the periphery”). 10 The parties dispute whether Figure 16 of the second German priority application discloses annular convexity and concavity. Pet. 42–43; Prelim. Resp. 45–46; Prelim. Reply 4–5; Prelim. Sur-reply 4. At most, the parties identify a material issue of fact with respect to these two claim elements that is best resolved on a full trial record. 11 At first blush, Figure 17A appears to show means 2.4.2 under a portion of element 27 of the capsule. Ex. 1047, Fig. 17A; Prelim. Sur-reply 4 depicted in Figures 16–18, which rely on toothed rings physically interacting with either the chamber, retaining arms, or a pinion. Ex. 1047, 12:22–31, 13:8–18. The second German priority application explains that means 2.4.2 physically interacts with retaining arms 30 (embodiments of Figures 16 and 17) or a pinon (embodiment of Figure 18), and if means 2.4.2 were not present in these embodiments, the capsule would either “drop through into a waste container” or could not be inserted through the insertion shaft. Id. at 12:22–27, 13:9–12, 13:16–35 (noting that in the embodiment disclosed in Figure 18 a pinon interacts with means 2.4.2 and only when means 2.4.2 “is formed complementary to the teeth of the means” can the capsule be inserted). Patent Owner does not sufficiently explain how a barcode could replace means 2.4.2 in these embodiments and still retain the capsule within the device or allow the capsule to enter the insertion shaft.” slip op. at 14

      “First, Yoakim expressly states that the capsule may use a “barcode,” and the plain and ordinary meaning of this term is a code that satisfies the construction adopted by the district court. To the extent Patent Owner has reason to believe that Yoakim does not apply the plain and ordinary meaning of the term “barcode,” and that one of ordinary skill in the art would have understood this fact, it is encouraged to present such evidence during trial. Second, in this obviousness inquiry the question is not whether a person of ordinary skill in the art is more likely to adopt a barcode or a bitcode, but whether one of ordinary skill in the art would have seen a benefit to applying the “barcode” of Yoakim under the flange of the capsule. See Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021) (“Our case law is clear. It’s not necessary to show that a combination is ‘the best option, only that it is a suitable option.’”). On that point, Jarisch expressly discloses the benefits of doing so. Ex. 1005 ¶ 22 (noting that applying the code at the bottom of the rim lowers the risk of the code becoming unreadable). As such, we determine that Petitioner sufficiently identifies where Yoakim discloses a barcode and explains why one of ordinary skill in the art would have placed such a “barcode” on the bottom of the capsule’s flange.” slip op. at 27

      “art include “(1) educational level of the inventor; (2) type of problems encountered in the art; (3) prior art solutions to those problems; (4) rapidity with which innovations are made; (5) sophistication of the technology; and (6) educational level of workers active in the field.” Envtl. Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696–697 (Fed. Cir. 1983) (citing Orthopedic Equip. Co. v. All Orthopedic Appliances, Inc., 707 F.2d 1376, 1381–82 (Fed. Cir. 1983)). Not all such factors may be present in every case, and one or more of these or other factors may predominate in a particular case. Id. Petitioner argues a person of ordinary skill in the art at the time of the invention “would possess at least a B.S. in chemistry or chemical or mechanical engineering and would have at least one year of experience working on control of automotive evaporative emissions,” and “would also understand the chemistry and physics associated with the phenomena of fuel vapor adsorption, desorption, and diffusion.” Pet. 28 (citing Ex. 1003 ¶ 17). Patent Owner does not dispute the level of ordinary skill in the art. We adopt Petitioner’s definition of the level of ordinary skill in the art because it is consistent with the ’553 patent and the asserted prior art.” slip op. at 11

    • Expert testimonyPatent owner expert creditedDecided for patent owner

      “Patent Owner and Dr. Rockstraw present peer-reviewed scientific literature demonstrating that gravimetric and volumetric measurement techniques were known to measure equivalent adsorption capacities and were viewed as compatible with each other. See Ex. 2022 ¶¶ 95–107 (addressing Anson7 (Ex. 2007), Belmabkhout8 (Ex. 1021), Zielinski9 (Ex. 2069)). For example, Belmabkhout reported similar results between measurements by gravimetric and volumetric instruments, except at very high pressures. Ex. 1021, 856–57. Zielinski reported “excellent agreement” between volumetric and gravimetric adsorption capacity measurements (Ex. 2069, 5–6); Dr. Zielinski (who oversaw the testing reported by Intertek 7 Anson, A., et al., “Hydrogen adsorption on a single-walled carbon nanotube material: a comparative study of three different adsorption techniques,” Nanotechnology 15 (2004), 1503. 8 Belmabkhout, Y., et al., “High-pressure adsorption measurements. A comparative study of the volumetric and gravimetric methods,” Measurement Science and Technology 15 (2004) 848. 9 Zielinski, J. et al., “High pressure sorption isotherms via differential pressure measurements,” Adsorption 13 (2007), 1–7. in Ex. 1020) also testified that he would expect capacity measurements for either a gravimetric or volumetric technique to yield the same results, or be “superimposable” under ideal conditions, because they represent “the same experimental measured quantities.” Ex. 2026, 52:11–53:7, 54:13–22, 69:12– 70:3, 139:8–19. Petitioner’s argument that these papers are not relevant because they do not address measurements on the adsorption capacity of n-butane (see Pet. Reply 26) is not persuasive, because Petitioner does not direct us to sufficient evidence showing a reason why measurements of n-butane’s adsorption capacity would have been subject to different measurement inconsistencies. Further, Petitioner’s argument about a 3% deviation in results between the measurement techniques reported in Anson and Belmabkhout is not persuasive because the papers’ conclusions suggest a person of ordinary skill in the art would not have seen such a deviation as significant (e.g., Ex. 1021, 849: “we have not observed important discrepancies” between gravimetric and volumetric measurements). Dr. Rockstraw also testifies as to numerous additional texts and standards that confirm persons of ordinary skill in the art understood that gravimetric and volumetric measurement techniques would provide consistent results when proper experimental protocols are followed and the instruments’ accuracy and precision are taken into consideration. See Ex. 2022 ¶¶ 88–91, 119–127. This evidence is essentially unrebutted by Petitioner. We find that the evidence submitted by Patent Owner as to the gravimetric and volumetric measurement techniques demonstrates that they were well established in the art as comparable methods of measuring adsorption capacity, and accordingly, not a basis for determining claim” slip op. at 16

      “Exhibit 2027. Paper 57 (“Pet. Mot.”). We do not discuss or cite Exhibit 2080 or paragraph 39 of Exhibit 2027 in this Decision, and consideration of them played no part in our determinations set forth herein. Because their presence in the record would not affect our analysis in this Decision, we dismiss as moot Petitioner’s motion with respect to these exhibits. B. Patent Owner’s Motion to Exclude Patent Owner filed a motion to exclude Exhibits 1015–1016, 1023– 1025, 1032, 1038–1039, 1042 (certain paragraphs), 1044, 1046–1049, and 1052–1054. Paper 56 (“PO Mot.”). Patent Owner groups these exhibits into four categories, which we apply in discussing the motion below. 1. Patent Owner moves to exclude Exhibits 1015 and 1046 as “irrelevant determinations from other adjudicative bodies regarding different patents.” PO Mot. 1. We do not discuss or cite these exhibits in this Decision, and have not considered them in reaching our decision herein. Because the presence of these exhibits in the record would not affect our analysis in this Decision, we dismiss as moot Patent Owner’s motion with respect to these exhibits. 2.
