Motorola guns for Apple again

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.
