Federal Circuit Upholds PTAB Ruling on Invalid Double Patenting in Cellect Case

In a significant development, the Federal Circuit refused to overturn a Patent Trial and Appeal Board (PTAB) conclusion that several claims in a series of patents related to phones and digital devices were not, in fact, patentable. The court supported the PTAB’s determination that the claims were invalid due to double patenting.

The patents, held by Cellect, were contested and subsequently reviewed by the PTAB. As per the PTAB’s findings, the significant overlap between the patents rendered them invalid. This judgment, now affirmed by the Federal Circuit, represents a formidable setback for Cellect and impacts its patent portfolio related to phone and digital device technologies.

Such decisions bear significant weight in shaping the contours of patent law and clarify the application of the doctrine of double patenting. Further, they can serve as a guide for corporations and law firms handling similarly complex patent matters.
