The proxy war between Apple and Google just got more interesting, with Google takeover target Motorola Mobility suing Apple again over alleged infringement of six patents.
A lawsuit filed in a US court claims Apple’s iPhone 4S infringes patents covering wireless antennae, software, data filtering and messaging. Motorola Mobility is fighting a concurrent lawsuit, also in the US, over the same patents, and won a preliminary injunction against Apple in Germany in December, that could lead to a ban on iPhone and iPad sales in the market.
The latest suit also targets Apple’s iCloud remote storage service, Reuters reports.
Apple has already been handed a preliminary loss in its own patent suit against Motorola Mobility, which had been filed with the US ITC.
Google arranged to buy Motorola Mobility for $12.5 billion (€9.5 billion) in August 2011, primarily to help defend Android by bolstering its weak wireless patent portfolio. However, regulatory approval of the acquisition is still pending.
