This week: The empires strike 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.
