On summary judgment, the United States District Court for the Western District of Wisconsin determined that Dell, Inc., Gateway, Inc., Toshiba America, Inc., and Toshiba America Information Systems, Inc. (collectively Defendants) did not infringe claims 17-20, 22, 24, and 26-28 of Computer Docking Station Corporation’s (CDSC’s) United States Patent No. 5,187,645 (’645 patent). Computer Docking Station Corp. v. Dell, Inc., Case No. 06-C-0032-C, 2007 U.S. Dist. LEXIS 2419 (W.D. Wis. Jan. 10, 2007) (Summary Judgment order).

The patentee disavowed an interpretation of “portable computer” as a computer with a built-in display or keyboard. Accordingly, the court affirmed the district court’s holding of no infringement.

KEY NOTES:

A term recited in a preamble of a claim may limit the scope of the claim if the specification and the prosecution history emphasize the term, even if the term is not found in the body of the claim.
