This week: The empire strikes back--Cisco Systems and Citibank file counter-suits against the patent holders making claims on videoconferencing and check-imaging, respectively; a defunct company with a less than stellar track record in the patent lawsuit business keeps filing; and a familiar player with a new name in E.D. Texas.
- Cisco Systems, Inc. v. Teleconference Systems, Llc Et Al. 09-cv-01550, N.D. California.
Teleconference Systems is a shell company set up by Acacia Research Corp., the Orange County-based patent-holding company that has, by one estimation, filed more patent suits than any other. Teleconference Systems was set up to enforce the 6,980,526 patent, which is related to videoconferencing; the patent is owned by Margalla Communications, a consulting company in Woodside, California, which presumably will share in any licensing booty Acacia wins.
On March 27, Teleconference filed its first patent lawsuit in Delaware, alleging that several companies in disparate industries have infringed the '526 patent. Teleconference is represented by Anthony Simon of The Simon Law Firm in St. Louis (formerly Simon Passante).
