On November 13, 2013, the PTAB issued its first final written decision in an IPR. Garmin International, Inc. v. Cuozzo Speed Technologies, LLC, Case IPR2012-00001. For Garmin, the petitioner, the decision was a resounding success, which resulted in the cancellation of every claim challenged in Garmin’s petition. In the coming weeks, we will analyze and discuss several intriguing aspects of the PTAB’s decision in a three-part series. In Part 1, we consider the PTAB’s denial of Cuozzo’s motion to amend the challenged claims. In Part 2, we discuss the PTAB’s determination that evidence provided by Cuozzo failed to swear behind the cited prior art references. Finally, in Part 3, we weigh-in on the PTAB’s willingness to affirm Garmin’s proposed four-reference obviousness rejection.
