“In a motion to amend, the patent owner bears the burden of proof to demonstrate patentability of its proposed substitute claims over the prior art and, thus, entitlement to the claims. Idle Free at 7. This does not mean that the patent owner is assumed to be aware of every item of prior art known to a person of ordinary skill in the art. However, the patent owner should explain in its motion why the proposed substitute claims are patentable over not just the prior art of record, but also prior art not of record but known to the patent owner: A patent owner should identify specifically the feature or features added to each substitute claim, as compared to the challenged claim it replaces, and come forward with technical facts and reasoning about those feature(s), including construction of new claim terms, sufficient to persuade the Board that the proposed substitute claim is patentable over the prior art of record, and over prior art not of record but known to the patent owner. The burden is not on the petitioner to show unpatentability, but on the patent owner to show patentable distinction over the prior art of record and also prior art known to the patent owner. Some representation should be made about the specific technical disclosure of the closest prior art known to the patent owner, and not just a conclusory remark that no prior art known to the patent owner renders obvious the proposed substitute claims. Id. This includes addressing the basic knowledge and skill set possessed by a person of ordinary skill in the art even without reliance on any particular item of prior art. Id. at 7–8; Toyota at 4–5. The petitioner then has the opportunity, in its opposition, to argue any deficiency in the patent owner’s motion and “come forward with specific evidence and reasoning, including citation and submission of any applicable prior art,” to rebut the patent owner’s position on patentability. Idle Free at 8.” slip op. at 16
- ScopeMotion to amend, grantedGranted
“1. No Broadening of Scope Proposed substitute claims in an inter partes review “may not enlarge the scope of the claims of the patent.” 35 U.S.C. § 316(d)(3); see 37 C.F.R. § 42.121(a)(2)(ii). In its Motion to Amend, Patent Owner proposes claim 13 as a substitute for claim 4, claim 14 as a substitute for claim 3, claim 15 as a substitute for claim 8, claim 16 as a substitute for claim 7, claim 17 as a substitute for claim 12, and claim 18 as a substitute for claim 11. Mot. 1–6. Each claim includes all of the limitations of the corresponding claim for which it is a substitute, and adds additional limitations. No limitations are removed. Petitioner in its Opposition does not dispute Patent Owner’s assertion that the proposed substitute claims do not enlarge the scope of the claims of the ’226 patent. See Mot. 8–9. We are persuaded that the proposed substitute claims do not enlarge the scope of the original patent claims.” slip op. at 11

“2. Written Description Support Pursuant to 37 C.F.R. § 42.121(b), a motion to amend in an inter partes review must set forth “[t]he support in the original disclosure of the patent for each claim that is added or amended,” and “[t]he support in an earlier-filed disclosure for each claim for which benefit of the filing date of the earlier filed disclosure is sought.”” slip op. at 12
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundReasonable expectation not foundDecided for patent owner
“Patent Owner argues that it would not have been obvious to incorporate the technique of Spring into a network data de-duplication system, as recited in the proposed substitute claims, because Spring “had very limited practical application in the network memory context.” Mot. 12. Patent Owner’s position is supported by the statement in McCanne ’376 that due to Spring’s small cache and first-in first-out replacement policy, “the efficacy of [Spring’s] approach is limited to detecting and exploiting communication redundancies that are fairly localized in time.” Ex. 1003 ¶ 20; see Mot. 12. The proposed substitute claims, which identify sync points from which forward and backward memory comparisons are performed, are not limited to only recently transmitted data. Patent Owner also asserts that the specific combination of “fine and coarse filtering of hash values” and “forward and backward memory comparison” limitations recited in the proposed substitute claims represents a practical solution to the “tradeoff” that exists with data de-duplication systems, and is not solved by any of the prior art of record. Mot. 12–13. Specifically, Patent Owner states that there is a “tradeoff” between the size of an index and the likelihood that an indexed segment will be matched. Id. Spring uses a small fixed-size cache and small packets, and, thus, works best for only recently transmitted data. Id. By contrast, according to Patent Owner, the proposed substitute claims provide a practical solution to the tradeoff by operating at the byte-level and using a combination of fine and coarse filters to identify sync points from which forward and backward memory comparisons are performed. Id. Patent Owner’s explanations regarding the prior art and why the proposed substitute claims allegedly would not have been obvious are supported by the record and are persuasive. We also note that although Petitioner addresses the “fine and coarse filtering of hash values” limitations in its Opposition (arguing that they are taught by Hsu), Petitioner does not argue that Hsu—or any other reference— teaches or suggests the “forward and backward memory comparison” limitations. Nor does Petitioner propose any specific combination of references that allegedly would have rendered obvious the proposed substitute claims as a whole. Thus, Patent Owner’s assertions regarding key aspects of the prior art, such as Spring, essentially are unrebutted.” slip op. at 23
