Samsung’s countersuits were “swift and strong” says an expert
On Thursday, Samsung filed its fourth response to Apple’s charge of “slavish” imitation: A suit in a California federal court alleging infringement by Apple (AAPL) of 10 Samsung communications patents.
“Samsung has mounted a swift and strong response to Apple’s initiative,” writes Foss Patent’s Florian Mueller. “The speed with which Samsung responded to Apple’s lawsuit in four different jurisdictions (in three of them within a week, and in the fourth one in less than two weeks) suggests that Samsung expected and, consequently, prepared for this.”
Apple’s complaint focused on elements of the patented look and feel of the iPhone and iPad that ended up in Samsung devices running Google’s (GOOG) Android OS. Samsung, which has a deep intellectual property portfolio of its own, has accused Apple of infringing on patents covering the underlying technology of cellular telephony, such as a particular method for “channel coding and multiplexing in CDMA communication system.”
The diagram above is from a Mueller PDF that lays out the legal battlelines step by step as they unfolded. His list of the Samsung patents (with links) is copied below the fold.
