Apple's facing yet another patent infringement lawsuit -- this time, in Florida, where a company called Operating Systems Solutions (OSS) is taking aim at OS X's fast booting operation. According to court documents, the plaintiff alleges that Cupertino's function (most prominently displayed on this year's MacBook Air refresh) violates at least one protected claim, which details a four-step method for speedy booting, and involves files like config.sys and autoexec.bat (seriously). Interestingly enough, the patent in question was originally granted to LG Electronics, back in 2002, but is currently owned by the little-known OSS. It's still unclear whether or not LG has any involvement with the suit, but we'll bring you the details as soon as they emerge.
