“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. Ex. 2011, 12:1–10, 19:6–25, 20:2–7. We therefore agree with Patent Owner that Exhibits 1013 and 1014 are the testimony of Mr. Wirén and should be excluded from evidence because Mr. Wirén is not a person of ordinary skill in the relevant art.

“Level of Ordinary Skill in the Art Based on the testimony of the parties’ witnesses, we determine that a person of ordinary skill in the art would have had a bachelor’s degree in paper science and engineering, chemical engineering, process engineering, mechanical engineering, or a related degree, with three to five years of experience in paperboard manufacturing, or a master’s degree in paper science and engineering, chemical engineering, process engineering, or mechanical engineering, or a similar field with a specialization in paperboard manufacturing. Ex. 1003 ¶ 24; Ex. 2003 ¶ 26.

“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. 2002)). “The standards for finding lexicography and disavowal are exacting.” GE Lighting Sols., LLC v. AgiLight, Inc., 750 F.3d 1304, 1309 (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.

Cir. 1993)) (alteration in original). “The enablement requirement ensures that the public knowledge is enriched by the patent specification to a degree at least commensurate with the scope of the claims. The scope of the claims must be less than or equal to the scope of the enablement. The scope of enablement, in turn, is that which is disclosed in the specification plus the scope of what would be known to one of ordinary skill in the art without undue experimentation.” National Recovery Techs. Inc. v. Magnetic Separation Sys., Inc., 166 F.3d 1190, 1195–96 (Fed Cir. 1999). [Although] a specification need not disclose what is well known in the art . . . , that general, oft-repeated statement is merely a rule 24 of supplementation, not a substitute for a basic enabling disclosure. . . . [W]hen there is no disclosure of any specific starting material or of any of the conditions under which a process can be carried out, undue experimentation is required; there is a failure to meet the enablement requirement that cannot be rectified by asserting that all the disclosure related to the process is within the skill of the art. It is the specification, not the knowledge of one skilled in the art, that must supply the novel aspects of an invention in order to constitute adequate enablement. Genentech Inc., 108 F.3d at 1366. Having considered the parties’ positions and evidence of record, summarized above, we determine that Petitioner has established that it is more likely than not that claims 1–5, 9, and 10 of the ’039 patent lack 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. See, e.g., Ex. 1001, Abstract, 4:22–29, 50:56–52:30, 71:19–22, 131:23–48, Figs. 1–19, Examples 2–16. Claim 1, however, recites ADCs” slip op. at 24

RulingsFinal written decision- BurdenUnpatentable
“Based on the full trial record, we find that Petitioner demonstrates by a preponderance of the evidence that the subject matter of claim 1 would have been obvious. Varenna 2011 teaches that neridronate “seems to possess an excellent efficacy profile” in treating CRPS. Ex. 1006, 233. In the context of reporting the use of “[n]eridronic acid for the treatment of bone metabolic diseases,” Gatti teaches that “[i]ntravenous high doses of bisphosphonates are increasingly used for the treatment of [CRPS].”13 Ex. 1008, 1305, 1308. Gatti also reports that a clinical trial of neridronic acid “is underway.” Id. Muratore teaches that neridronate was “efficacious in the treatment of [CRPS].” Ex. 1007, 89. Thus, on this record, each of these references sufficiently teaches the efficacy of neridronic acid or its salt in treating CRPS, suggesting that a person of ordinary skill in the art would have been motivated to use neridronic acid in treating CRPS. With respect to the limitation of claim 1 requiring that the neridronic acid be “parenterally administer[ed],” each of Varenna 2011, Gatti, and Muratore teaches intravenous administration of neridronic acid. Ex. 1006, 233; Ex. 1007, 89; Ex. 1008, 1308. Intravenous administration is a type of parenteral administration. Ex. 1004 ¶ 44. 13 Gatti uses the terms “reflex sympathetic dystrophy syndrome” and “algodystrophy.” Ex. 1008, 1308. On the present record, we interpret both of these terms as synonymous with “complex regional pain syndrome,” “CRPS,” “complex regional pain syndrome type I,” “CRPS I,” “reflex sympathetic algodystrophy,” “reflex sympathetic dystrophy,” and “causalgia.” Ex. 1006, 227 (equating “algodystrophy,” “complex regional pain syndrome type I,” and “CRPS I”); Ex. 1007, 89 (using the term “reflex sympathetic algodystrophy”); Ex. 1019, 713 (equating “complex regional pain syndrome,” “CRPS,” “reflex sympathetic dystrophy,” and “causalgia”). Harden teaches that the Budapest Criteria are used as “clinical diagnostic criteria for CRPS” and that they include changes in skin blood flow, by reference to the symptoms of “temperature asymmetry” and “skin color asymmetry.” Ex. 1009, 274 (Appendix II). Further, Harden teaches that 69.4% of patients diagnosed with CRPS were observed on examination to exhibit temperature asymmetry, and 83.9% were observed on examination to exhibit skin color asymmetry. Id. at 271 (Table 2). Thus, Harden teaches that a majority of patient with CRPS suffer from changes in skin blood flow. Because Varenna 2011, Gatti, and Muratore teach that neridronic acid is effective in treating CRPS, the combination of any of those references with Harden14 would have suggested to a person of ordinary skill in the art that neridronic acid would be effective in alleviating changes in skin blood flow associated with CRPS.

“Assuming that “October 2011” is hearsay, it is still admissible evidence under Rule 807 of the Federal Rules of Evidence. See Opp. Mot. 3–4 (asserting this hearsay exception). Under Rule 807, a statement “is not excluded,” even if it is hearsay, if it meets two requirements. First, the statement must be “supported by sufficient guarantees of trustworthiness— after considering the totality of circumstances under which it was made and evidence, if any, corroborating the statement.” Fed. R. Evid. 807(a)(1). Second, the statement must be “more probative on the point for which it is offered than any other evidence that the proponent can obtain through reasonable efforts.” Id. at 807(a)(2). Here, both requirements are satisfied. The statement “October 2011” on the face of Varenna 2011 is offered to prove that Varenna 2011 was published in October 2011. This statement is accompanied by several guarantees of trustworthiness. The statements “Received on July 15, 2011” and “Accepted on August 30, 2011,” when offered as corroboration of the October 2011 publication date, are not hearsay. Fed. R. Evid. 801 (statement is hearsay only if offered in evidence “to prove the truth of the matter asserted in the statement”). Accordingly, they may be admitted for this purpose, and they corroborate a publication in October 2011. Moreover, Exhibits 1038 and 1040 also provide some evidence that Varenna 2011 was published in October 2011. Ex. 1038, 1 (article with same title as Varenna 2011 published in “Fascicolo 5 2011”); Ex. 1040, 1 (“Fascicolo 5 2011” published in 2011). Thus, the record contains sufficient guarantees of trustworthiness of Varenna 2011’s statement that Varenna 2011 was published in October 2011. See Opp. Mot. 3 (citing Ex. 1004 ¶¶ 39–40). We find that Varenna 2011’s statement, indicating that the reference was published in October 2011, is “more probative on the point for which it is offered than any other evidence that the proponent can obtain through reasonable efforts.” Fed. R. Evid. 807(a)(2). It is difficult to imagine evidence more probative of the publication date of a journal article than the article’s own contemporaneous statement about when it was published.19 See Opp. Mot. 2–4 (for well-supported arguments on point). Accordingly, we determine that the exception of Rule 807 applies, and we conclude that the statement “October 2011” in Varenna 2011 should not be excluded.” slip op. at 48

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
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundUnpatentable
“Petitioner’s asserted references provides data showing that administering neridronic acid improves the symptoms of CRPS. PO Resp. 18–19. But “[o]bviousness does not require absolute predictability of success. . . . [A]ll that is required is a reasonable expectation of success.” In re O’Farrell, 853 F.2d 894, 903–904 (Fed. Cir. 1988). It is sufficient that Varenna 2011, Gatti, and Muratore would have informed the ordinarily skilled artisan that successful treatment of CRPS and its symptoms was likely; there is no requirement that Petitioner show that the prior art taught that success was certain.” slip op. at 15
- Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner
“qualifies as a printed publication under 35 U.S.C. § 102. PO Resp. 4–17; PO Sur-Reply 14–21. “To qualify as a printed publication, a reference ‘must have been sufficiently accessible to the public interested in the art.’” Blue Calypso, LLC v. Groupon, Inc., 815 F.3d 1331, 1348 (Fed. Cir. 2016) (quoting In re Cronyn, 890 F.2d 1158, 1160 (Fed. Cir. 1989)). “A reference will be considered publicly accessible if it was disseminated or otherwise made available to the extent that persons interested and ordinarily skilled in the subject matter or art exercising reasonable diligence, can locate it.” Id. (quoting Kyocera Wireless Corp. v. Int’l Trade Comm’n, 545 F.3d 1340, 1350 (Fed. Cir. 2008)) (internal quotation marks omitted). Thus, there are two ways to show that a reference was sufficiently accessible: show it was disseminated or show it was “otherwise made available to the extent that” interested people of ordinary skill in the art could have located it after exercising reasonable diligence. Id. Here, according to Petitioner, the asserted references “are articles published in periodical journals by an identified and reputable publisher.” Reply 3.11 Petitioner argues that the references were “disseminated on the[ir] stated publication date[s].” Id. at 5. We agree.” slip op. at 18
