“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).

“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. Cir. 2003)). “[S]uch an overlap creates a presumption of obviousness, and . . . the burden of production falls upon the patentee to come forward with pertinent evidence that the overlapping range would not have been obvious in light of the prior art.” Id.

“Finally, we are reminded that “a sufficient description of the genus . . . requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad, 598 F.3d at 1350. “[F]unctional claim language can meet the written description requirement when the art has established a correlation between structure and function.” Id. Here, however, the challenged claims are directed to methods using a wide range of different types of compounds purported to be “IL-15/IL-15R inhibitors” that are not part of a known or readily identifiable class, do not target the same biological pathway, do not have any common structural features, and do not appear to always function as inhibitors. See Ex. 1018, Abstr., 1575–77, 1579; Ex. 1046, 189:4–19, 191:15–192:15, 193:18–196:22, 198:21–199:21, 197:12–198:19, 200:1–8, 207:11–14, 203:3–10, 207:15–21, 236:12–24; Ex. 1047 ¶¶ 19–23, 56, 63–64, 80–85.

“598 U.S. at 610. A “specification may call for a reasonable amount of experimentation to make and use a patented invention. What is reasonable in any case will depend on the nature of the invention and the underlying art.” Id. at 613. But the person of ordinary skill in the art cannot be left with merely “a hunting license” or obligated to engage in “painstaking experimentation” or “trial and error” to “see what works.” Id. at 614. Patent Owner argues that “the IL-15/IL-15R inhibitors disclosed in the specification were known in the art and “share the common ‘general quality’ of inhibiting a pathway known to be relevant to and having ‘particular fitness for the particular purposes’ of (id.) treating certain autoimmune diseases by blocking IL-15 signaling.” Sur-reply 14 (citing Ex. 1011, 22; Ex. 2013, 3; Ex. 2017, Abstr.; Ex. 2024, 17; Ex. 2025, 2–3, 6; Ex. 2027, 4; Ex. 2028, 9; Ex. 2029, 4; Ex. 2031, 23; Ex. 2118, 53:22–54:9; Ex. 1018, 1; Ex. 2005, ¶¶ 52–63, 80–83, 130; Ex. 1046, 231:20–25). Patent Owner’s argument is unavailing, however, because the record shows that different IL-15-specific inhibitors may operate in different ways that may result in differential effects, some of which may not include inhibition at all. See Ex. 1047 ¶¶21, 23, 40, 71; Ex. 1018, Abstr., 1576, 1579; Ex. 2013, 4:1– 8; Ex. 2014, 4:9–15; Ex. 2015 ¶ 22; Ex. 2025, 4:34–5:2; Ex. 1046, 166:21– 24, 168:25–169:5, 207:23–209:22, 210:4–17, 210:24–211:6; Ex. 1011, 1:67–2:4; Ex. 2005 ¶¶ 116, 134. Thus, we find that the record supports Drs. Abbas and Plott’s testimony, which we credit, that a person of ordinary skill in the art would be forced to hunt down and test every compound through painstaking Ex. 1002 ¶¶ 85–90, 92; Ex. 1047 ¶ 53 (Dr. Plott’s testimony that the “specification of the ’505 patent is essentially a black box (so far as which aspects of IL-15 signaling it inhibits and how it operates), leaving the reader to guess through trial and error which molecules might operate similarly to ChMBC7 and which do not.”); Ex. 1004 ¶ 61 (Dr. Plott’s testimony that “from the perspective of a clinician, the amount of experimentation required would be extremely burdensome and success would be speculative.”); Ex. 2007, 93:16–97:25, 38:208; Ex. 1046, 234:20–236:11. This is due to the fact that the claims (without limit) encompass any inhibition of any one of the various types of IL-15 signaling and various versions of the receptor, and even implicate other compounds that act on different targets but which inhibit the IL-15 signaling pathway. See Ex. 1047 ¶¶ 10, 53, 68; Ex. 2005 ¶ 71; Ex. 1046, 254:4–255:11, 158:12–160:20. The evidence has shown that IL-15/IL-15R inhibition is complicated and unpredictable, with some inhibitors also capable of enhancing forms of IL-15 signaling rather than preventing it. See Ex. 1047 ¶¶ 10, 25–26, 53; Ex. 2013, 2:10–18; Ex. 2014, 2:12–20; Ex. 2015 ¶ 3; Ex. 2025, 2:10–18; Ex. 2078, 267.” slip op. at 32

“As explained in our Institution Decision (Dec. Inst. 5–6), we do not discern a substantive difference between the parties’ respective definitions for the level of ordinary skill in the art. Although Petitioner states a POSITA must have one to two years of postdoctoral research experience and Patent Owner’s definition requires at least five years of “research experience,” Patent Owner’s definition does not indicate a specific time for that research (i.e., it could include research during or after a doctoral program). Neither party addresses or contests the other party’s definition in their post-institution papers. See generally PO Resp.; Pet. Reply; PO Sur-reply. Accordingly, we find the parties’ respective definitions to be equivalent and consistent with the level of ordinary skill in the art as reflected by the prior art in this proceeding. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Moreover, we find that Dr. Shaner and Dr. Somers are both qualified to opine from the perspective of a skilled artisan as both are persons of at least ordinary skill in the art, based on either party’s definition.

“amount.” Pet. Reply 14. Patent Owner, however, argues that we erred in our construction because the Specification explicitly defines “effective amount” to mean “the amount of herbicide required to achieve at least about 65% phytotoxicity of conventional [i.e., wild, non-mutant] rice (e.g., red rice) in field applications.” PO Resp. 10 (quoting Ex. 1001, 6:34–37). Because the inventors served as their own lexicographers, Patent Owner asserts the Specification’s express definition controls. Id. at 10–11 (citing Martek Biosciences Corp. v. Nutrinova, Inc., 579 F.3d 1363, 1380 (Fed. Cir. 2009) (“When a patentee explicitly defines a claim term in the patent specification, the patentee’s definition controls.”)). Nevertheless, Patent Owner acknowledges that the “less than 10% injury” language “is indeed a limitation of the ’346 Patent claims.” Id. at 11. Having considered the arguments and evidence presented at trial, we agree with Patent Owner that the inventors acted as their own lexicographer to define “effective amount” and that that definition governs its meaning. Phillips, 415 F.3d 1316 (“[O]ur cases recognize that the specification may reveal a special definition given to a claim term by the patentee that differs from the meaning it would otherwise possess. In such cases, the inventor’s lexicography governs.”). We, therefore, construe the term “effective amount” to mean “the amount of an herbicide required to achieve at least about 65% phytotoxicity of conventional rice (e.g., red rice) in field applications.” As explained further below, however, whether incorporated into the construction of “effective amount” or not, the claim language itself further requires that the “effective amount” encompass a specific range of amounts of herbicide (i.e., 14 g AI/Ha to 40 g AI/Ha of quizalofop) and cause “less than 10% injury” to the mutant rice. See Ex. 1001, claim 1.” slip op. at 10

“Mankin would derive the herbicide range suggested by Patent Owner and Dr. Somers from the “rules of thumb,” that range is much broader than the claimed range. Claim 1 recites that the effective amount is 14 g AI/Ha–40 g AI/Ha of quizalofop, but, according to Dr. Somers’s calculations from the Assure II herbicide label, a POSITA would understand the effective amount to be 19.25–154 (or 19.25–184.8) g AI/Ha. Ex. 2036 ¶ 54; PO Resp. 38. Patent Owner does not identify anything in the specification that would allow a POSITA to “immediately discern” the specific range limitations of the claims. See General Hospital, 888 F.3d at 1372. As the Federal Circuit has stated, “one cannot disclose a forest in the original application, and then pick a tree out of the forest and say here is my invention.” Purdue Pharma, 230 F.3d at 1326. Thus, we are not persuaded that the disclosure of a broad range of effective amounts via the Assure II herbicide label coupled with Dr. Somers’s undisclosed “rules of thumb” provide written description support for the narrower range limitations of the claims. Moreover, we agree with Petitioner that Patent Owner is impermissibly working backward from the claimed ranges to determine whether Dr. Somers’s “rules of thumb” can be used to re-create the claimed range from the herbicide label. Pet. Reply 15. That is not the test for written description. Written description “requires a statement of an invention, not an invitation to go on a hunting expedition to patch together after the fact a synthetic definition of an invention.” Indivior UK Ltd. v. Dr. Reddy’s Labs. S.A., 18 F. 4th 1323, 1329 (Fed. Cir. 2021). Accordingly, we are not persuaded that Dr. Somers’s “rules of thumb” applied to the extrinsic herbicide label would be understood by a POSITA as a description in Mankin of the range limitation of the claims. Rather, as Dr. Somers concedes, his “rules of thumb” in conjunction with the herbicide label represent a starting point for a POSITA to test plants to determine what the effective amount range should be. See Ex. 2036 ¶ 53 (referring to a “dose response analysis” between 0.5x and 4x). But “a ‘mere wish or plan’ for obtaining the claimed invention is not sufficient.” See Centocor Ortho Biotech, Inc. v.

“We are not persuaded. Given the state of the art in 2017, and the known availability of the G2096S seeds at that time, we find the ’346 patent specification enables the claims. The ’346 patent specification clearly describes the G2096S mutant ACCase rice and its use in the claimed method for treating rice. See, e.g., Ex. 1001, 2:37–45, 57:51–61. Contrary to Petitioner’s assertion, the ’346 patent specification has not omitted the G2096S herbicide tolerant rice. Rather, the ’346 patent specification expressly identifies the G2096S mutant rice that possesses the phenotype of tolerance to the effective amounts of herbicides, and describes the method for treating that mutant rice with those effective amounts. See, e.g., id. at 8:8–12; 57:51–61. Thus, we are not persuaded that we erred in relying on Hinga’s seed deposits to determine that Petitioner has failed to meet its burden to prove that the ’346 patent specification fails to enable the challenged claims.

“labels is akin to relying on literature that clearly provides, on its face, the missing disclosure, as in Falkner. Id. On the contrary, Patent Owner’s argument makes clear that the herbicide labels, by themselves, are insufficient to describe the claimed range limitation. Specifically, because the label ranges do not align with the claimed ranges, Dr. Somers had to make additional assumptions and inferences to support Patent Owner’s written description argument. For example, to calculate the potential effective amount range of herbicides, Dr. Somers applied several different “rules of thumb,” none of which are disclosed in the Mankin specification. See Ex. 2036 ¶¶ 34, 54. According to Dr. Somers, to determine the effective amount for a plant with an unknown response to an herbicide, a POSITA “would naturally test the lowest label (1X) rate of the herbicide, along with a few rates below (starting at about half-X) and above the 1X rate (up to 4X) of the herbicide, to determine the effective dose for this ‘uncharacterized’ plant.” Id. ¶ 34. Dr. Somers refers to this as a “dose response analysis.” Id. ¶ 53. In other words, to determine what the actual effective amount of herbicides should be, Dr. Somers explains that a POSITA would have to test the plants at these “rule of thumb” amounts to determine the effective range. Id. ¶ 34. Given the additional assumptions and inferences that must be made to the herbicide labels to arrive at the range limitations, we are not persuaded that relying on the extrinsic herbicide labels for written description support is proper in this case. That said, even if we were to allow Patent Owner to rely on the herbicide labels and the “rules of thumb” for determining the effective herbicide dose, Patent Owner admits that the ranges calculated from the herbicide labels are broader than the range limitations of the claims. See PO Resp. 39. As Petitioner notes, however, the Mankin Application does not provide any guidance as to whether the effective amount range of herbicide would include a 0.5x dose, a 2x dose, or the 4x dose, such that a POSITA could immediately discern the claimed range from the herbicide label.17 Pet.

“Dr. Somers, however, relies on the label for Fusilade II, which is a different fluazifop-P-butyl herbicide with a different range of 52.98–103.96 g AI/Ha, which—not surprisingly—aligns more closely with the claimed range of at least 56–150 g AI/Ha. Ex. 2036 ¶ 52. We note that Fusilade II does not appear to be one of the listed herbicides in Table 1, whereas Fusilade DX is. Ex. 2034 ¶ 219 (listing “Fusilade, Fusilade 2000, Fusilade DX, ICI-A 00009, ICI-A 00005, SL-236, IH-773B, TF-1169, and Fusion” as examples of synonyms and trade names for fluazifop-P-butyl). Regardless, that the dose range differs for the same herbicide calls into question the credibility of Dr. Somers’s assertion that a person of ordinary skill in the art would have been able to discern the claimed range limitation by simply looking at the EPA-approved herbicide labels (and applying his “rules of thumb”).18, 19” slip op. at 33

“In our Decision on Institution, although we agreed with Patent Owner that the ordinarily skilled artisan would have experience in the treatment of coagulopathy, we applied a broader definition of a person of ordinary skill in the art, as articulated by Drs.

“We agree with Petitioner that the ’248 patent provides an express definition of “treat” and “treatment.” The Specification states, “[i]n the present text the term ‘treat’ or ‘treatment’ of a pathology means the prophylaxis and/or therapy and/or cure of this pathology.” Ex. 1001, 5:19– 21. This definition includes “cure” as a separate concept from therapy, and further provides that therapy includes “partial or total” alleviation of symptoms. Id. at 5:21–24. The ’248 patent does not define or otherwise describe “treating a coagulopathy” as requiring any specific duration of therapeutic efficacy; therefore, a person of ordinary skill in the art would understand that partial alleviation of symptoms and a shorter duration of therapeutic efficacy is encompassed in “treating a coagulopathy” as recited in claim 1. Claim 16, which depends from claim 1, supports a construction of “treating a coagulopathy” that does not require complete alleviation of symptoms or permanent therapeutic efficacy. Claim 16 recites the “modified FIX polypeptide is expressed at a level that reduces and/or prevents hemorrhages.” Ex. 1001, 46:34–36. Because claim 16 depends from claim 1, this means that “treating a coagulopathy” as recited in claim 1 encompasses merely reducing hemorrhages, i.e., partial alleviation of symptoms. Accordingly, based on the intrinsic evidence, including the express definition of the terms “treat” and “treatment,” we construe “treating a coagulopathy” as prophylaxis and/or therapy and/or cure of the coagulopathy which includes partial alleviation of symptoms, for any duration of therapeutic efficacy. We determine that we need not explicitly construe any other claim terms.” slip op. at 11
