NEW YORK When an Internet company plunks down $12.5 billion to buy a struggling cellphone company for its collection of patents, it's another sign that, for the high-tech industry, patents have become a mallet wielded by corporations to pummel their competitors.

Google Inc. announced the deal to buy Motorola Mobility Holdings Inc. on Monday, specifically for its trove of 17,000 patents. Google needs them to shield companies like HTC Corp. and Samsung Electronics Co. who make phones based on Google's Android software from lawsuits filed by Microsoft Corp. and Apple Inc.

"Google is not acquiring Motorola for the sake of its technology or its research," said James Bessen, a lecturer at Boston University and co-author of a book on the patent system. "Patents have become legal weapons they're not representing ideas anymore."

The trend, decades in the making, raises questions that pending patent legislation in Washington only begins to answer.

Google's multi-billion bid to get its hands on Motorola's output of legal paperwork is the culmination of a "bubble" in the value of patents relating to smartphones that started last year, as Microsoft and Apple mounted their legal attack. Industry watchers say that bubble may deflate now that Google is set to gain the protection of Motorola's patents in a deal that's set to close late this year or early next.

But an underlying problem will keep growing: patent filings and lawsuits that distract companies and sap resources that are better spent on other things.

Engineers spend their time writing patents rather than inventing things, or reworking products just to avoid patent infringement. Customers put off purchases because of pending lawsuits, and independent software developers close up shop because they can't afford licensing fees.

"If you have to pay $12.5 billion

to play, you can sense why maybe an individual who has a great idea would feel discouraged," said Julie Samuels, a patent lawyer with the Electronic Frontier Foundation, a technology-oriented civil liberties group. "It affects the whole economy."

It wasn't always this way. The U.S. software industry got its start with nary a patent filed, and on the hardware side, patent suits were rare until the mid-1980s. That was when calculator and chip maker Texas Instruments Inc., on the brink of extinction, decided to see if it could make some money from its patent portfolio. It started filing lawsuits and demanding money from companies with infringing products. It saved the company.

IBM Corp. latched on to TI's lead in patent licensing in the mid-90s, when it was down on its luck. That coincided with courts broadening the types of patents allowed. Patents on software and "business methods," with vague, broad claims, were now accepted.

Since then, an arms race has slowly escalated in the industry. Companies found that the best defense against a patent suit from a rival was to have a patent portfolio to wield as a deterrent: "Sue me and I'll sue you back," is the message Google is sending by buying Motorola.

Motorola is already suing Apple over several patents, including one that purports to cover the act of sending address data between two phones. …
