Google has claimed that Apple should have licensed the feature on their phones which allows the phone to ignore touches when the phone is held close to the users head. The patented feature was owned by Motorola which Google acquired during its take over of the business in 2011.This latest claim by Google has been blocked by US’s International Trade Commission (ITC). It is the most recent of a number of claims that have been launched against Apple, which includes six claims of infringement from Motorola itself, originally launching in October 2010 before Google announced its take over. These six included three others that the ITC said were not legitimate claims and Motorola then dropped a further two, leaving this latest IP claim the only one outstanding.In this instance the ITC said that the disabling of the touch screen was an obvious feature as it had been something that firms had already been trying to solve, as previously there were issues around users accidentally dialling.The number of claims that Google has made and the poor success rate goes someway to show just how difficult it is to put a value on intellectual property and how difficult it is for businesses to prove an infringement claim.The contents of this article are intended for general information purposes only and shall not be deemed to be, or constitute legal advice.
