EMG Tech sues Google for patent infringement over Chrome mobile app

The mobile version of Google's Chrome browser is at the centre of a patent suit, which claims that the browser violates EMG Technology's "simplified navigation system" for smartphones and tablets.

According to the suit, which was filed earlier this week in a Texas district court, the technology company wants the court to ban the distribution of the mobile browsers and award damages.

EMG's patent was issued on 21 October, 2008, Elliott Gottfurcht, lead inventor of EMG's patent portfolio, said in a statement.

By "displaying mobile webpages on smartphones and tablets" EMG alleged that Google is stepping on the toes of EMG's patented system, which uses unique inputs to manipulate a touch screen for zooming and scrolling.

EMG did not specify the amount of compensation the company wants, saying in the suit that "it would be difficult to ascertain the amount of compensation that would afford EMG adequate relief for such future and continuing acts."

Google did not immediately respond to a request for comment.

EMG is no stranger to slapping patent suits on tech companies.

In November 2008, the California-based company sued Apple, complaining that the iPhone infringed on a patent for navigating the web on cell phones. Sound familiar?

EMG took a swing at Microsoft in August 2009, alleging that the software giant violated two patents: one to navigate Internet control on a TV, the other for the "method of manipulating a region on a wireless device screen for viewing, zooming and scrolling internet content."

Google released a beta version of Chrome for Android in February; the stable version is included in the latest version of Android, dubbed Jelly Bean. Chrome for iOS made its debut last month at Google I/O, reaching the top spot on the App Store charts after one day.
