It's just the latest legal salvo in the rapidly escalating war over the intellectual property that underlies several popular mobile devices. No less than four major mobile companies are currently suing each other over cell-phone technology.
Motorola filed three complaints -- with the International Trade Commission, the Northern District of Illinois and the Southern District of Florida -- over 18 patents that relate to "early-stage innovations developed by Motorola in key technology areas" including wireless email, antenna design (hopefully not this one), software applications and location-based services.
Motorola has requested that the ITC bar further sales of the allegedly infringing products, as well as halt the "the marketing, advertising, demonstration and warehousing of inventory for distribution and use of such imported products in the United States."
"We Had No Choice"
The handset maker issued a sharply worded statement justifying the move: "Motorola has innovated and patented throughout every cycle of the telecommunications industry evolution, from Motorola's invention of the cell phone to its development of premier smartphone products," said Kirk Dailey, corporate vice president of intellectual property at Motorola Mobility, in a statement. "We have extensively licensed our industry-leading intellectual property portfolio, consisting of tens of thousands of patents in the U.S. and worldwide."
Last Friday, Motorola itself was the target of a lawsuit by Microsoft (MSFT), which claims Motorola's Android-based smartphones use Microsoft technology that's "essential to the smartphone user experience." Android is the rapidly growing mobile-phone operating system developed by Google (GOOG).
In March, Apple sued HTC, which, like Motorola, is one of Google's key Android partners, for allegedly infringing on 20 patents related to the iPhone, including aspects of its touch screen, user interface and user-sensing technology. In May, HTC struck back, suing Apple for allegedly violating HTC patents.
Somewhere, the lawyers are celebrating.
