From the Opinion

The passage below is extracted verbatim from the opening of the document. It has not been editorially summarized — consult the full opinion for the court's complete reasoning.

British Telecommunications PLC owns U.S. Patent No. 6,397,040, which describes and claims methods, sys- tems, and apparatuses for selecting information sources to provide to a user via a telecommunication system. British Telecom sued IAC/InterActiveCorp and several of its sub- sidiaries (collectively, IAC) in the United States District Court for the District of Delaware, alleging that IAC in- fringed six British Telecom patents, including the ’040 pa- tent. The district cou rt held that all claims of the ’040 patent are invalid under 35 U.S.C. § 101.
