Sony Attack on Walker Digital Patent

Scott Daniels | October 3, 2011

Earlier this year Walker Digital (of Priceline.com fame) sued Sony and others for infringement a patent claiming an apparatus for providing information to a customer about a video program.  Sony has now replied to that suit by requesting reexamination of the Walker patent (see ex parte Request No. (10)). 

Reexamination was also requested for three more Round Rock Research patents, related to different technologies (see ex parte Request Nos. (2), (3) & (4)).  Round Rock bought the three patents from Micron.  It is not yet clear who has filed these reexamination requests for patents not involved in litigation. 

The following inter partes requests were filed:
