United States: PTAB Adds More Feedback On Previously Presented Art/Arguments (325(D))

Additional Informative Decisions 325(d)

Today the Patent Trial & Appeal Board (PTAB) added to its growing stockpile of cases that address the meaning of "same or substantially the same prior art or arguments" under 35 U.S.C. § 325(d). This growing body of decisions is welcome news for Patent Owners as it emphasizes the scrutiny given to AIA trial petitions that attempt to revisit prior art and arguments of a previous proceeding.

The PTAB has designated the following decisions informative.

Kayak Software Corp. v. International Business Machines Corp., Case CBM2016-00075 (PTAB Dec. 15, 2016) (Paper 16). In this decision, the Board exercised its discretion under 35 U.S.C. § 325(d) and declined to institute review of the claims under obviousness grounds because the record indicated that the cited prior art was previously presented to and extensively considered by the Office during prosecution. The Board further was not persuaded that the incremental addition of an already considered reference was sufficient to avoid § 325(d), but explained that the presence of certain factors, including a limited prosecution history, clear errors in the prosecution, and/or the cursory consideration of the prior art may weigh against the exercise of discretion to deny institution under § 325(d).

Becton, Dickinson & Company v. B. Braun Melsungen AG, Case IPR2017-01586 (PTAB Dec. 15, 2017) (Paper 8). In this decision, the Board weighed a non-exclusive list of factors and concluded to exercise its discretion under 35 U.S.C. § 325(d) and declined to institute review of the claims under certain obviousness grounds. The non-exclusive factors the Board considered were: (1) the similarities and material differences between the asserted art and the prior art involved during examination; (2) the cumulative nature of the asserted art and the prior art evaluated during examination; (3) the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis of rejection; (4) the extent of the overlap between the arguments made during examination and the manner in which Petitioner relies on the prior art or Patent Owner distinguishes the prior art; (5) whether Petitioner has pointed out sufficiently how the Examiner erred in its evaluation of the asserted prior art; and (6) the extent to which additional evidence and facts presented in the Petition warranted reconsidered of the prior art or arguments.

Previous 325(d) decisions designated as informative:

Unified Patents, Inc. v. Berman, Case IPR2016-01571, Case IPR2016-01571 (PTAB Dec. 14, 2016) (Paper 10)
Hospira, Inc. v. Genentech, Inc., Case IPR2017-00739 (PTAB July 27, 2017) (Paper 16)
Hospira, Inc. v. Genentech, Inc., Case IPR2017-00777 (PTAB Aug. 22, 2017) (Paper 7)
