Software Cos. Eye Key Patent Case In Supreme Court

JOELLE TESSLER

WASHINGTON (AP) — With the technology industry looking on, the Supreme Court on Monday will explore what types of inventions should be eligible for a patent in a pivotal case that could undermine such legal protections for software.

A ruling that sides with the Patent Office could bar patents on processes and methods of doing business, such as online shopping techniques, medical diagnostic tests and procedures for executing trades on Wall Street. And it might even undercut patents on software.

In a worst-case scenario for the high-tech industry, the ruling could invalidate many existing software patents or at least make them more difficult to defend in lawsuits. And it could make such patents harder to obtain in the future because software is generally patented as a process for doing something rather than as a physical invention.

"Technology companies care about this case because it will define what you can and cannot get a patent on," said Emery Simon, counselor to the Business Software Alliance, which represents large technology companies including Microsoft Corp. and Intel Corp. "The scope of patentability could have ramifications for the path that technology takes."
