Management Comment
This patent is one of the patents involved in Wi-LAN’s SDNY case 10 CV 432. It has now become very common for Defendants in patent infringement lawsuits to, as part of their defense strategy, file requests for re-examination of patents at issue in such actions. It is expected that the U.S. Patent and Trademark Office will respond to this request within the next 3 months.
