After Sony filed a lawsuit against LG in December last year, the South Korean electronics t LG filed two patent lawsuits against its Japanese competitor with a southern California court. The company also announced it has filed a patent-infringement complaint with the U.S. International Trade Commission. Sony’s lawsuit claims LG shipped phones and modems that infringe certain Sony patents, and LG claims Sony violated patent rights over TVs, PCs and cameras.

“South Korea’s LG Electronics Inc. said Tuesday that it filed a patent-infringement complaint with the U.S. International Trade Commission against Japanese electronics maker Sony Corp. last week, asking the U.S. trade watchdog to block Sony from selling some high-margin televisions and game consoles.”

Mobile is still maturing, and so are the big players, who are looking to gain the biggest market share possible. This is why lawsuits will continue on to shake-up the mobile space, determing who will the dominant companies will be, what segments of the industry will they control and will affect future industry growth as a whole.

Intellectual property lawsuits have been constantly circling the mobile industry lately, beyond just the most recent case above. We covered Paul Allen’s patent suits against Apple, among others: Apple that is, and Google, Facebook, Yahoo, AOL, eBay, Office Depot, Office Max, Staples and Netflix as well. Apple and Microsoft have also been active in court on the aggressive side, and Motorola sued Microsoft over, of course, patent infringement.
