Cisco sues German firm over switch patent
NETWORK FIRM Cisco filed suit against German firm Teles AG, anticipating a patent action from the Berlin firm.
AG Teles owns patent number 6,954,453 and Cisco wants a district court in Washington DC to rule the patent invalid. It is what we call pre-emptive action.
A quick shufty at the US patents site reveals this patent number is a Method for transmitting data in a telecommunications network and switch for implementing said method. The patent was filed by Teles AG Informationstechnologien on 7th of October 1997.
Teles has already sued Cisco in Germany alleging it breached both European and German patents. And lawyers for Cisco said they had "a reasonable apprehension" that Teles would sue Cisco in America.
