Cisco Seeks Declaratory Judgment of Noninfringement of New Optical Networking Patent

September 28, 2021

On September 28, 2021, the USPTO granted to Ramot at Tel Aviv University Ltd., the “Business Engagement Center” of Tel Aviv University, another patent in a family of nine already, all generally related to converting digital electric data into modulated optical streams. Three of those patents are in litigation against Cisco and Acacia Communications (acquired by Cisco this past March) that has been stayed—one case in the Eastern District of Texas (against Cisco) and the other in the District of Delaware (against Acacia) to await the outcome of a set of ex parte reexams. Both companies have now filed a complaint in Delaware seeking a declaratory judgment of noninfringement of the newly issued patent.
