(p. A3) The sweeping patent initiative — backed by a business coalition dominated by technology companies such as Cisco Systems Inc. and Microsoft Corp. — would . . . shift the balance of power of the U.S. patent system. It would make it a bit harder for holders to protect patents. Advocates of the legislation contend the current system encourages patent litigation and costly judgments against infringers — and stifles innovation. They say the proposals are designed to bring patent rules in line with the rapidly changing U.S. economy, where inventions often reflect hundreds of potentially patentable ideas.
Mark Chandler, Cisco’s general counsel, dismissed concerns that non-U.S. companies might gain some advantage by the bill. He said the proposed changes would strengthen companies at “the heart of innovation in the American economy,” better positioning them to compete at home and abroad.
Opponents of the legislation argue that it would make it easier for foreign competitors to legally copy patented methods and products.
