“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. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

“Exhibits 1013 and 1014 are also not admissible as expert testimony because Mr. Wirén is not “qualified as an expert by knowledge, skill, experience, training, or education.” Fed. R. Evid. 703. “To offer expert testimony from the perspective of a skilled artisan in a patent case—like for claim construction, validity, or infringement—a witness must at least have ordinary skill in the art. Without that skill, the witness’ opinions are neither relevant nor reliable.” Kyocera Senco Indus. Tools Inc. v. Int’l Trade Comm’n, 22 F.4th 1369, 1376–77 (Fed. Cir. 2022). Mr. Wirén does not meet our definition of a person of ordinary skill in the art. See Section II.B, supra. That definition is based on the undisputed testimony of Messrs. Zotterman and Klass. Ex. 1003 ¶ 24; Ex. 2003 ¶ 26. Although Mr. Wirén has a Master’s of Science in chemical engineering, he lacks any experience or specialization in paperboard manufacturing.

“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.

Cir. 2014). “To act as its own lexicographer, a patentee must ‘clearly set forth a definition of the disputed claim term,’ and ‘clearly express an intent to define the term.’” Id. (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.

The scope of the claims must be less than or equal to the scope of the enablement.

In particular, we are persuaded based on the record at this stage of the proceeding that the Specification does not enable the full scope of the claims. The Specification focuses on dolastatin/auristatin derivatives and does not describe novel ADCs having non-dolastatin/auristatin derivative drug moieties. Ex. 1001, Abstract. For example, the Specification states that “there is a clear need in the art for dolastatin/auristatin derivatives having significantly lower toxicity, yet useful therapeutic efficiency [sic]” and purports that “[t]hese and other limitations and problems of the past are addressed by the present invention.” Id. at 4:25–29 (emphasis added). Moreover, each embodiment, example, figure, and assay disclosed in the Specification appears to use a drug moiety that is a dolastatin/auristatin derivative.

“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

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.

“Petitioner has not shown by a preponderance of the evidence that the gravimetric and volumetric methods provide fundamentally different measurements of adsorption capacity. 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).

“INTRODUCTION A. Background Grünenthal GmbH (“Petitioner”) filed a Petition (Paper 2, “Pet.”) requesting a post-grant review of claims 1–30 of U.S. Patent No. 9,931,352 B2 (Ex. 1001, “the ’352 patent”).

“regardless of whether the preambles are limiting. Even if the preambles are limiting, their scope is so broad as to be hardly different from no limitation at all. The specification of the ’352 patent defines “treating” as “includ[ing] any kind of treatment activity, including the diagnosis, cure, mitigation, or prevention of disease in man or other animals, or any activity that otherwise affects the structure or any function of the body of man or other animals.” Ex. 1001, 7:43–47. This definition exhibits “reasonable clarity, deliberateness, and precision” and is “‘set out . . . within the patent disclosure’ so as to give one of ordinary skill in the art notice of the change” in meaning. In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994) (quoting Intellicall, Inc. v. Phonometrics, Inc., 952 F.2d 1384, 1387–88 (Fed. Cir. 1992)). Accordingly, we give effect to this definition of “treating.” Under the definition of “treating” in the specification of the ’352 patent, “[a] method of treating” hyperalgesia (claim 1) or edema (claim 17) “associated with complex regional pain syndrome” means a method of diagnosing, curing, mitigating, or preventing that condition associated with complex regional pain syndrome, or otherwise affecting the structure or any function of the body of someone suffering from the condition associated with complex regional pain syndrome. To the extent that this requires carrying out the method on a patient suffering from hyperalgesia (claim 1) or edema (claim 17) associated with complex regional pain syndrome, this is already part of the method recited in the body of the claims, Ex. 1001, 90:39–43, 91:23–27, so the preambles provide no additional limitation. To the extent that the preambles require some particular result to be brought about, that result could be the diagnosis, cure, mitigation, or prevention of the symptom in question, or it could be any effect at all on the structure or any function of the patient’s body. Thus, even when construed as limiting, the preambles provide little, if any, further restriction on the scope of the challenged claims beyond that set forth in the body of the claims. Moreover, as discussed below with respect to the asserted grounds of obviousness, Petitioner directs us to evidence that the prior art teaches or suggests the subject matter of the preambles, even when those preambles are construed as limiting in accordance with the meaning of “treating” provided in the specification.8 Thus, whether or not we treat the preambles as limiting, the outcome does not change. Given this circumstance, we treat the preambles of the challenged claims as limiting, and assign them a meaning consistent with the specification’s definition of “treating.”” slip op. at 8

“Moreover, “[a]pplicants can define . . . claim scope during prosecution,” just as they can in a patent specification. Teva Pharms. USA, Inc. v. Sandoz, Inc., 789 F.3d 1335, 1343 (Fed. Cir. 2015). Here, during prosecution of the ’419 patent, the applicant stated that “[t]he term ‘hair coloring agent’ refers to a colorant or pigment that is customarily used in hair care products, which changes the color or tone of the hair it is applied to based on visual inspection.” Ex. 1005, 7. To define specific terms used to describe an invention, the applicant need only set out the definition “with reasonable clarity, deliberateness, and precision,” “so as to give one of ordinary skill in the art notice of the change” in meaning. In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994). On the present record, the definition of the term “hair coloring agent” set out in the prosecution history of the ’419 patent is sufficiently clear, deliberate, and precise to give a person of ordinary skill in the art notice that the term is used in the ’419 patent in a manner that does not include substances other than “colorant[s] or pigment[s] that [are] customarily used in hair care products,” even if those other substances might be described as “hair coloring agents” outside the context of the ’419 patent. Ex. 1005, 7. Accordingly, we should give effect to that definition. Because Patent Owner’s proposed construction of “wherein the mixture does not contain a hair coloring agent” gives effect to the prosecution history’s definition of “hair coloring agent,” we adopt Patent Owner’s proposed construction for purposes of the present decision. Thus, on the present record, and for purposes of the present decision, we construe “wherein the mixture does not contain a hair coloring agent” as “wherein the mixture applied to the hair does not have a colorant or pigment that is customarily used in hair care products, which changes the color or tone of the hair it is applied to based on visual inspection.”” slip op. at 6

“wherein the mixture does not contain a hair coloring agent.” Pet. 36–39; Prelim. Resp. 39–40.

Petitioner’s argument with respect to these limitations is that Hawkins ’266 and Hawkins ’270 disclose the use of DSF-65, that the ’592 patent describes the use of Risella X 420, and that, according to Dr. Fetzer, DSF-65, Risella X 420, EK35, and EnviroKleen all have similar compositions. Pet. 14, 28– 29; Ex. 1002 ¶¶ 33–34.

This conclusory statement is not sufficient to satisfy Petitioner’s burden under 37 C.F.R. § 42.204(b). As discussed above, at most, Petitioner has demonstrated that the DSF-65 product disclosed in Hawkins ’266 and Hawkins ’270 and the EK35 and EnviroKleen products all have compositions similar to the Risella X 420 described in the Specification of the ’592 patent, without demonstrating that those products have the compositions of the fluids claimed in the ’592 patent.
