New York, NY – The Patent Trial and Appeal Board (PTAB) issued final decisions this week finding all claims of two Purple Leaf patents related to payments to be unpatentable. The PTAB granted Askeladden’s petitions for Inter Partes Review (IPR) of U.S. Patent Nos. 8,527,407 and 8,744,963 early last year.


Askeladden’s Patent Challenge Committee decided to petition the PTAB for review of the two Purple Leaf patents as part of Askeladden’s Patent Quality Initiative.


Purple Leaf previously accused eBay and PayPal of infringing its ’407 and ’963 patents, and sued Amazon, Google, and several other companies asserting infringement of another patent related to the ’407 and ’963 patents.


“With these decisions from the PTAB, the invalidated patents may no longer be used as the basis for meritless and wasteful assertions,” said Sean Reilly, General Counsel of Askeladden. “Decisions like these further our goal of promoting and protecting innovation in the financial services industry.”


Askeladden is represented by Merchant & Gould P.C.
