It's been about three months now since intellectual property company Lodsys started threatening smartphone application developers with patent infringement lawsuits over technology used for in-app software upgrades. Apple has since moved to intervene in the suit, arguing the developers are covered under the license Apple already holds for the Lodsys technology in question.
At the time, patent expert Florian Mueller, who has been watching the smartphone patent war since its early days, criticized Google for not doing the same thing in order to protect Android developers also involved in the suit. Google, however, decided on a different approach. PCMag.com reports the company has asked the U.S. Patent and Trademark office to review the validity of the patents at issue. Mueller calls the move "too little, too late," noting that the court in the infringement case is unlikely to grant a stay pending the patent office's determination.
No decision has been made on Apple's motion to intervene.
In other Google smartphone news, the Mountain View, Calif.-based company announced its intention to purchase Motorola Mobility. It's undoubtedly another step in Google's plan to boost its patent portfolio so that it can protect itself from future lawsuits like this one.
