“May” expresses a possibility. The Specification reflects this interpretation of “may” when it states that “[i]n one embodiment, the organic material is not lyotropic. Thus, the organic material may not be a phospholipid.” Ex. 1001, 8:27–28 (emphasis added). One of ordinary skill would understand from this that the organic material “may not be” a phospholipid if the organic material is not lyotropic. It follows that if the organic material is lyotropic, then the organic material may be a phospholipid. Reading the statement “[t]he organic material may not be . . . a phospholipid” (id. at 8:59–63) in light of the earlier stated possibility that the organic material may be a phospholipid if the organic material is lyotropic, one of ordinary skill in the art would interpret “may not be” as excluding phospholipids under some conditions, not under all conditions. Taking the Specification’s discussion about phospholipids as exemplifying the permissive nature of the word “may,” we are unpersuaded that in stating that “[t]he organic material may not be [PMMA], a polyvinylidene difluoride-containing polymer, such as [PVDF] or PVDF- TrFE-CTFE, or a phospholipid, such as [DHPE]’” (Ex. 1001, 8:59–63), the specification “contains a clear and unmistakable disavowal of the compounds PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE” and “disclaims the listed compounds” from the “organic material” of the claims under all conditions, as Patent Owner argues. Prelim. Resp. 6–7. Moreover, the claims themselves limit the “organic material” only to the extent that it is “barocaloric cooling or heating agent” and can perform in the manner claimed. See Ex. 1001, claim 1, supra. As broadly worded, the claims do not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE per se from the group of organic materials employed by the claimed method. Adopting Patent Owner’s construction would impermissibly import a limitation (i.e., not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE) into the claims. For the reasons stated, at this stage of the proceeding, we agree with Petitioner’s broad construction of “organic material.” We do not adopt Patent Owner’s proposed construction whereby PMMA, PVDF, PVDF- TrFE-CTFE, and DHPE are excluded from the scope of the claim term “organic material.” The parties are invited to address this issue further during trial, if desired. slip op. at 11

“Petitioner shows that (a) Mañosa (i.e., inorganic compounds such as Ni-Mn-In, Gd5Si2Ge2, and La-Fe-Co-Si) and (b) Patel (i.e., PVDF-TrFE- CTFE) teach materials exhibiting inverse BCEs. Pet. 59 (citing, inter alia, Ex. 1007, pages 4–8; Ex. 1009, 1, 4–5; Ex. 1004 ¶ 108). In our view, at this stage, Petitioner sufficiently shows (via the five reasons listed supra) why it would have been obvious to one of ordinary skill in the art to substitute the barocaloric cooling or heating agent of Patel for that taught in Mañosa, thereby reaching the claimed method with a reasonable expectation of success.

“invention. Graham, 383 U.S. at 17–18. Petitioner contends that a person of ordinary skill in the art (sometimes abbreviated herein as “POSITA”): would have had a bachelor’s degree in mechanical engineering or biomedical engineering and two or more years of experience in biomechanical engineering, biomedical engineering, and/or spinal implant devices. A person could also have qualified as a POSITA with some combination of more formal education (e.g., an M.D.) and less technical experience or less formal education and more technical or professional experience in the foregoing fields, and would have had further appreciation of various technical concepts in this field. Pet. 18 (citing Ex. 1002 ¶¶ 32–35). Patent Owner does not dispute Petitioner’s proposal. See Response 8.

“We credit Mr. Drewry’s testimony that it would have been well within the ordinary skill of a POSITA to make the proposed modifications.

To the extent Mr. Culbert testifies otherwise, we do not find such testimony persuasive. Indeed, Olmos itself further supports Mr. Drewry’s testimony that a POSITA would have known how to modify dimensions to fit specific needs and make changes necessary to adapt features from one embodiment to fit another. See Ex. 1006 (Olmos) ¶¶ 153, 188 (providing a range of implant sizes and noting that “specific dimensions” of any disclosed 9 Patent Owner’s citation to Mr. Drewry’s deposition transcript at 87:13– 88:9 appears to be incorrect.

Patent Owner’s expert Dr. Ko critiques Petitioner’s proposed definition as “incomplete, because it lacks any requirement for experience, or access to individuals with experience, in JAK inhibition, deuteration, and AA formulations.” Ex. 2059 ¶ 16. However, neither Dr. Ko nor Patent Owner explains what difference this additional direct experience would have provided to an artisan with the skill level proposed by Petitioner, particularly when Petitioner’s definition includes “experience in treating hair loss disorders,” and for which the record contains evidence that existing JAK inhibitors such as ruxolitinib had been identified as causing reversal of hair loss caused by AA.

For example, Dr. Goodrich has not explained sufficiently why, or identified evidence that shows the invention described in the ’322 Patent falls into a very predictable field, one of ordinary skill in the art would have possessed the requisite skills to make the proposed combinations, or one of ordinary skill in the art reasonably would have anticipated the combination to function in an ordinary and expected way. See Rothman v. Target Corp., 556 F.3d 1310, 1319–20 (Fed. Cir. 2009). 21 Finally, Petitioner cites Sobel (Ex. 1011)1 as support for it being “obvious to randomly select a subset of a group of computing choices.” Pet. 30. Petitioner characterizes Sobel’s teachings too broadly. Ex. 2030 ¶ 117. Sobel is directed to “providing software updates to a random sample of computers,” not to randomly selecting models. Pet. 30. Thus, we are not persuaded that Sobel is relevant to the inquiry here. For the reasons stated above, Petitioner has not shown by a preponderance of the evidence that claims 8, 17, and 25 were obvious over the combination of Khazan and Agrawal.” slip op. at 21

“We have considered Patent Owner’s argument that the Petition fails to propose properly a level of ordinary skill in the Petition itself and that the level of skill suggested by Petitioner’s Declarant is higher than the level used in the related district court case. PO Resp. 6–8. Nevertheless, Patent Owner does not argue that the combinations of the teachings of the references are beyond the level of skill of a person of ordinary skill in the relevant art. The level of skill in the art might be gleaned from the prior art itself. See Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163–64 (Fed. Cir. 1985) (“A specific finding on the level of skill in the art is not . . . required where the prior art itself reflects an appropriate level and a need for testimony is not shown.”). Here, we find that the prior art adequately reflects an appropriate level of skill and that Patent Owner does not demonstrate a need for testimony or other evidence to establish the level of skill of a person of ordinary skill in the relevant art. Also, we find that, even though Dr. Goodrich suggests a level of skill higher than the level used in the related district court case, Patent Owner does not show sufficiently that any such difference in level of skill is material to the obviousness analysis in this case.” slip op. at 28

“contends that this construction is necessary to clarify that the challenged claims require monitoring registry accesses because Petitioner’s declarant, Dr. Michael T. Goodrich, testified during his deposition that the records “may be records that don’t have direct impact on the registry.” Id. at 7–8. Even if Patent Owner’s characterization of Dr. Goodrich’s deposition testimony is accurate, Petitioner does not argue in the Petition or the Reply that the challenged claims do not require monitoring registry accesses. See Pet. 13–15, 21–32; Pet. Reply 1, 3–8. As such, there does not appear to be a dispute that requires claim construction. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”). Nonetheless, in order to avoid any ambiguity, we provide an express construction of the phrase “records regarding processes that access the operating system registry.” We determine that the evidence supports Patent Owner’s proposed construction. The written description of the ’084 patent consistently indicates that records of processes are obtained by monitoring accesses to the operating system registry. Ex. 1001, col. 5, ll. 6–18, col. 8, ll. 9–10, col. 8, ll. 22–24, col. 13, ll. 28–31, col. 13, ll. 46–52. In addition, Petitioner acknowledges that the challenged claims require monitoring accesses to the operating system registry. Tr. 12:15–13:3. Patent Owner’s proposed construction, however, omits the claim terms “processes” and “operating system,” which are part of the phrase being construed. Ex. 1001, col. 23, ll. 32–34. Therefore, we modify Patent Owner’s proposed construction to include those terms. Specifically, we construe the phrase “records regarding processes that access the operating system registry” to mean “records regarding processes obtained by monitoring accesses to the operating system registry.”1” slip op. at 6
