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.
The lawsuit, filed in a Florida court in the US, covers the iPhone 4S and the iCloud remote storage service, Reutersreported.
It claims infringement of patents related to wireless antennae, software, data filtering and messaging. Motorola Mobility is fighting a concurrent lawsuit, also in Florida, over the same patents.
Motorola also won a preliminary injunction against Apple in Germany in December, that could lead to a ban on iPhone and iPad sales in the market
But Apple was this month 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 in August 2011 – and is now waiting regulatory approvals to seal the deal – primarily to help defend Android by bolstering its weak wireless patent portfolio.
Apple's numerous patent lawsuits against Samsung and other vendors have been interpreted by some as a by-proxy attack on the OS, and Steve Jobs has been quoted in his autobiography that he had been willing to wage “thermonuclear war” against Android.
But the war hasn't been one-sided, with Samsung mounting several unsuccessful court bids to have iOS devices banned in various markets.
