In the next two years, a small cast of officials spent about 23 hours — the time generally allotted for reviewing a new application — examining the three dozen pages before recommending rejection. The application, for a voice- and text-based search engine, was “an obvious variation” on existing ideas, a patent examiner named Raheem Hoffler wrote. Over the next five years, Apple modified and resubmitted the application eight times — and each time it was rejected by the patent office.
Until last year.
On its 10th attempt, Apple got patent 8,086,604 approved. Today, though the patent was not among those Vlingo and Nuance fought over, it is known as the Siri patent because it is widely viewed as one of the linchpins of Apple’s strategy to protect its smartphone technologies.
In February, the company deployed this new patent in a continuing lawsuit against Samsung that could radically reorder the $200 billion smartphone business by giving Apple effective ownership of now-commonplace technologies, software experts say.
Patent 8,086,604’s path to approval “shows there’s a lot wrong with the process,” said Arti K. Rai, an intellectual property expert at Duke University School of Law who reviewed the patent application for The Times. That patent, like numerous others, is an example of how companies can file an application again and again until they win approval, Ms. Rai said.
