Bloomberg reported Monday that the software juggernaut filed a complaint with the U.S. International Trade Commission accusing TiVo of violating four Microsoft patents. The patents at issue cover technology related to "program schedules and selection, controlling the interface, and a way to restrict use of the DVR based on the program's rating," the story says.
Microsoft wants the agency to prohibit the importation of TiVo's set top digital video recorders to the U.S. The devices are primarily made in Mexico. Apparently, the case before the ITC is a second avenue of attack in the company's intellectual property battle with TiVo. Microsoft previously filed a separate court action alleging TiVo infringed seven (different) patents. The parties are currently in settlement negotiations regarding that action.
TiVo representatives would not comment on the ITC action, but Microsoft spokesperson Kevin Kutz told Bloomberg:
We remain open to resolving this situation through an intellectual property licensing agreement.
