Apple Inc., Appeal 2016-1599 (Fed. Cir. May 11, 2017).

  • Analogous Art: A Tale of Two Decisions In two recent PTAB decisions, Tissue Transplant Technology Ltd. & Human Biologics of Texas, Ltd., v. Mimedx Group, Inc., Case IPR2015-00420, Paper 25 (PTAB July 7, 2016) and Dexcowin Global, Inc., v. Aribex, Inc.

  • “It’s a Bird, It’s a Plane, NO it’s a Granted Motion to Amend.” We previously reported the May 9, 2016, Patent Office’s study that the PTAB rarely grants motions to amend.  There, we explained that patent owners rarely file motions to amend and, even when such motions are filed, the PTAB rarely grants such motions.

This case is thus a rare example of the... More
