“Claim terms need only be construed to the extent necessary to resolve the controversy. Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011). Here, we do not need to define the outer bounds of the term “pharmaceutical batch” because the parties’ dispute over this term centers on the issue of storage stability.7 Patent Owner argues “the correct construction 6 The parties use the terms “purification” and “isolation” interchangeably in the papers. We use the term “isolation” in this Decision. 7 The parties agree on the “pharmaceutical” aspect of the term. We note the ’901 patent defines “pharmaceutically acceptable” as “being useful in preparing a pharmaceutical composition that is generally safe, non-toxic and neither biologically nor otherwise undesirable and includes being useful for veterinary use as well as human pharmaceutical use.” Ex. 1001, 5:27–31.” slip op. at 19

“[A]n invention is construed not only in the light of the claims, but also with reference to the file wrapper or prosecution history in the Patent Office.” Graham, 383 U.S. 1, 33. “The prosecution history of a related patent can be relevant if . . . it addresses a limitation in common with the patent in suit.” Advanced Cardiovascular Sys., Inc. v. Medtronic, Inc., 265 F.3d 1294, 1305 (Fed. Cir. 2001); see also Elkay Mfg. Co. v. Ebco Mfg. Co., 192 F.3d 973, 980 (Fed. Cir. 1999) (“When multiple patents derive from the same initial application, the prosecution history regarding a claim limitation in any patent that has issued applies with equal force to subsequently issued patents that contain the same claim limitation.”). Here, the Specification of the ’901 patent includes the same language “crude treprostinil salts can be stored as raw material at ambient temperature” addressed in the prosecution of the parent ’623 application. Ex. 1001, 17:5–6. More importantly, challenged claim 6 recites the same limitation “preparing a pharmaceutical product . . . after storage” the applicant expressly interpreted there. See Ex. 2028, 193. Because “the same claim limitation is at issue, prosecution disclaimer made on the same limitation in an ancestor application will attach,” the applicant’s interpretation of “storing”/“storage” during the prosecution of the ’623 application applies here. See Omega Eng’g, Inc., v. Raytek Corp., 334 F.3d 1314, 1333 (Fed. Cir. 2003). slip op. at 23

“Sunovion Pharm., Inc. v. Teva Pharm. USA, Inc., 731 F.3d 1271, 1276 (Fed. Cir. 2013). Here, step (c) of challenged claim 1 requires “contacting the solution comprising treprostinil from step (b) with a base to form a salt of treprostinil.” Ex. 1001, 17:27–29 (emphasis added). The claim language itself, thus, dictates that the solution formed in step (b), and not treprostinil isolated from step (b), is the starting material for forming a salt in step (c). The Specification of the ’901 patent supports our determination. Indeed, the Specification touts that one of the advantages of the disclosed process is that “the treprostinil salts can be synthesized from the solution of treprostinil without isolation,” because “[t]he impurities carried over from intermediate steps (i.e. alkylation of triol and hydrolysis of benzindene nitrile) are removed during the carbon treatment and the salt formation step.” Ex. 1001, 17:1–11. As a result, we agree with the argument presented in the Patent Owner Response that “claim 1 requires the solution in which treprostinil is formed be used directly in the next salt-forming step without isolating treprostinil in between.” See PO Resp. 11.” slip op. at 27

“pharmaceutical manufacturing.” Id. at 23. We find Patent Owner’s definition of the skill level too narrow. Patent Owner relies on the declaration of Dr. Pinal, who testifies that the ’901 patent is “focused on the production of pharmaceutical compositions and products, on a commercial batch-size scale.” Ex. 2002 ¶ 91; see also id. ¶ 92 (opining that organic and medicinal chemists do not have the “requisite skill set for the large-scale manufacture” of drugs); PO Resp. 24 (arguing an ordinarily skilled artisan is aware of “problems encountered in preparing a commercial-scale pharmaceutical product”).” slip op. at 29

“We find that Dr. Prisco’s testimony is a reasonable interpretation of how Taylor works if the bellows are bidirectional, and the bellows are expanded and contracted when the suction cup is sealingly engaged. Figure 3 of Taylor shown above appears to support Dr. Prisco’s testimony that the bellows may be expanded or contracted from the initial position shown in Figure 3 and does not appear to show any valve or second opening in the bellows to provide unidirectional flow as Dr. Jensen, Patent Owner’s declarant, asserts. Also, as Petitioner asserts, Taylor indicates that a squeeze ball may be substituted for the bellows expressly indicating a device with a bidirectional flow. Although Patent Owner raises valid arguments concerning a common definition of bellows indicating unidirectional flow and provides testimony from Dr. Jensen reasonably supporting such a position, these dueling positions create a genuine issue of material fact that we weigh in favor of Petitioner on institution.

“We conclude from a review of Fang and Taylor that they are not substantially the same art nor is Petitioner making substantially the same argument as was presented the Office during prosecution of the ’061 Patent based on Fang. We find that the way in which Fang and Taylor work appear to be materially different. Fang appears to apply only suction to the skin whereas Taylor, with the sealingly connected suction cup, appears to apply a cyclical vacuum that Dr. Prisco testifies meets the claim limitations requiring generation of a pattern of negative and positive pressures, modulated with respect to a reference pressure. Ex. 1002 ¶¶ 62–64, 75. Thus Taylor appears to teach the claim element Patent Owner argued during prosecution was missing from Fang. Also, in applying factors (b) and (d) of Becton, Dickinson, because of such differences noted above, we find that Taylor is not cumulative of Fang, which was considered and applied by the Office during prosecution of the ’061 Patent. 4. Conclusion Thus, we find that Taylor and Fang are not substantially the same art, nor were substantially the same arguments based on these references presented in the Petition and during prosecution of the ’061 Patent, respectively. As discussed above, because Petitioner primarily relies on Taylor in all four grounds for teaching the modulation of positive and negative pressures with respect to a reference pressure as required by all of the challenged claims, we also find that, overall, the same or substantially the same art was not previously presented to the Office nor were the same or substantially the same arguments previously presented to the Office. Therefore, we do not need to reach the application of the remaining Becton, Dickenson factors relating to whether the Petitioner has demonstrated a material error by the Office. Thus, we decline to exercise our discretion under § 325(d) to deny institution of an inter partes review here.” slip op. at 12

“Petitioner has also provided a reasonable motivation to combine the teachings of Lee and Guan. Lee comprises a dildo with an extension which directly stimulates the clitoris, a body part. Ex. 1006, Fig. 1; Ex. 1002, ¶¶ 72, 134–137. Guan discloses an apparatus, which indirectly stimulates a body part. Ex. 1007, 3; Ex. 1002 ¶ 137. Given the teaching in the art of the problems with direct stimulation versus indirect stimulation, we agree on this record with Dr. Prisco that one skilled in the art would have had a reason to substitute the indirect stimulation device of Guan for the direct intensive and is best decided on a full record.

“Owner’s argument. As we noted in our Decision, the issue of whether undue experimentation is required to practice the claimed invention is evaluated using the factors outlined in In re Wands, a fact based inquiry. Dec. 8. Our conclusion for purposes of institution that undue experimentation would be required to practice the claimed invention was based, not only on Dr. Braun’s statement to that effect, but on the detailed analysis presented by Petitioner and Dr. Braun of all of the Wands factors as supported by the evidence of record. Dec. 14–15. show that the experimentation required was other than routine and found it unpersuasive at the institution stage of the proceeding. Id. Patent Owner’s argument was based on the premise that Dr. Braun’s opinion regarding nonenablement was based on the number of experiments and not whether the experiments were routine. Prelim. Resp. 2–4. This argument ignores the fact that our consideration of Dr. Braun’s opinion was based on an analysis of all of the Wands factors, a fact based inquiry that includes analyzing the minimal guidance presented in the Specification and the unpredictability of cancer treatments and unpredictable nature of CPIS, and not merely the number of experiments required. Id. at 15; Ex. 1002 ¶ 166; In re Morsa, 713 F.3d 104, 109 (Fed. Cir. 2013) (“Enablement is a question of law based on underlying factual findings.”). Although we acknowledge Patent Owner’s argument in support of its position that the claimed subject matter is enabled, we remind Patent Owner that, for purposes of deciding whether to institute a post-grant review, we view a genuine issue of material fact in the light most favorable to the petitioner. 37 C.F.R. § 42.208(c).
