On remand, the Board instituted inter partes review of claims 1–17, 20–21, 24–26, and 29–34 on all grounds stated in the Petition.
RulingsRemand decision- Director reviewOther
“Petition did not establish a reasonable likelihood that Petitioner would prevail with respect to at least one of the challenged claims, and did not institute inter partes review. Paper 17 (“Inst. Dec.”). Petitioner requested Director review of our decision denying institution (Paper 18 (“Request”)). The Director delegated review of the decision to a Delegated Rehearing Panel. Paper 19. Patent Owner was granted the option to file a response to Petitioner’s Request (Paper 22 (“Request Resp.”)). The Director Review Panel (“DRP”) vacated our decision and remanded the case to this panel with a revised construction for claim 1. Paper 23 (“DRP Dec.”).” slip op. at 2

“An inter partes review may be instituted only if “the information presented in the petition . . . and any [preliminary] response . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect (2018). Upon reconsideration of the briefing and the evidence of record in light of the DRP’s claim construction, we conclude that Petitioner has established a reasonable likelihood of prevailing on its assertion that at least one of the challenged claims is unpatentable. Accordingly, we grant institution of inter partes review of claims 1–17, 20–21, 24–26, and 29–34 of the ’682 patent.” slip op. at 2

“We find that Petitioner has demonstrated a material error by the Office in the prior consideration of Morales-Sanfrutos, Straus, Singh, and Lees. For instance, under the second prong of Advanced Bionics, we consider “(c) the extent to which the asserted art was evaluated during “(e) whether Petitioner has pointed out sufficiently how the Examiner erred in its evaluation of the asserted prior art.” Becton, Dickinson, 17–18. We agree with Petitioner that the Office overlooked Morales- Sanfrutos’ and Singh’s teachings during examination and reexamination. Pet. 79. Although Morales-Sanfrutos, Straus, and Singh were listed on an IDS, they were not the subject of a rejection during examination or reexamination. Moreover, for the reasons discussed below at this stage with regard to Petitioner’s grounds over Morales-Sanfrutos, as evidenced by Straus, and over Singh, Petitioner sufficiently demonstrates that the Office materially erred in overlooking Morales-Sanfrutos’s and Singh’s teachings regarding their linker structures. Id. Further, to the extent the Lees’ teachings were considered during examination and reexamination, Lees’ disclosure of a homobifunctional sulfone linker was overlooked. Lees’ homobifunctional linker, which Patent Owner argues is substantially similar to Harris’ homobifunctional linker, which Petitioner chiefly relies upon in Grounds 2–5, was not the subject of a rejection during examination. Pet. Resp. Brief 1; Prelim. Resp. 25–26. We agree with Petitioner that only Lees’ heterobifunctional linker was applied in a rejection during examination. Pet. Resp. Brief 1; Ex. 1018, 42–43, 62. 4. Conclusion For the foregoing reasons, we decline to exercise discretion to deny institution under § 325(d).” slip op. at 27

To the extent a more precise definition is required, we apply Petitioner’s unopposed definition for purposes of determining whether to institute review because it is consistent with the disclosures of the asserted prior art references.” slip op. at 15

The Board cancelled original claim 1 and denied substitute claim 2 for lack of written-description support; it did not reach the obviousness or enablement grounds.
RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“ordinary skill is inappropriate because it “requires qualifications that exclude even the sole inventor of the ’190 Patent, Dr. Edward Neuwelt.” MTA Opp. 1. According to Petitioner, Dr. Neuwelt is “a neurosurgeon,” not a pediatric oncologist, and lacks the requisite “at least 2 years” experience in platinum-based therapies. Id. (citing Ex. 1003, 18; Ex. 1038, 98:9–17, 100:15–101, 4). We agree with Petitioner. It is well settled that inventors are typically persons skilled in the field of the invention. Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005) (en banc). Petitioner presents persuasive evidence to show that under Patent Owner’s proposed definition of the level of ordinary skill, Dr. Neuwelt, the sole inventor, would not qualify as an ordinarily skilled artisan, because he is not a pediatric oncologist, even though he is considered “one of the world leading experts on this compound [STS] and otoprotection” and “an expert in the area of [STS] as a . . . drug to use in children with medulloblastoma.” Ex. 1038, 98:9–17, 99:17–18, 101:18–102:13.” slip op. at 10

“Paragraph 102 of Dr. Rassekh’s Declaration, however, does not support Patent Owner’s assertion. Instead, Dr. Rassekh testifies that [t]he stratum of previous craniospinal radiation therapy contained 8 participants: 2 of the 4 (50%) participants receiving STS had hearing loss compared to 4 of the 4 (100%) participants not receiving STS, and none of the hearing loss assessments were changed at the 1 year follow up period. (Ex. 1001 at 20: 28-32, 47-50.) Ex. 2024 ¶ 102. Dr. Rassekh offers no opinion on how many osteosarcoma patients with prior cranial irradiation and how many medulloblastoma patients with prior cranial irradiation had hearing loss.” slip op. at 20

“F. Petitioner’s Asserted Unpatentability Grounds In light of our determination above that Patent Owner has not shown sufficient written-description support for proposed substitute claim 2 in the ’243 application, we do not reach the grounds of unpatentability set forth in Petitioner’s Opposition.
