“Samsung’s got to be pretty happy right about now, after learning that the US Patent and Trademark Office has filed an initial ruling declaring Apple’s rubber-banding patent invalid, as reported by FOSS Patents. The news was good enough that Samsung decided to share it with friends, that is, if US Federal Judge Lucy Koh can be considered a friend. According to the ruling, which Florian Mueller says isn’t final, all 20 claims of Apple’s patent (No. 7,469,381) are now invalid, including one that the iPhone maker had leveraged against Samsung in their recent legal showdown. The office found that Apple’s invention was either anticipated by prior art (from Lira and Ording) or, in some cases, simply obvious.” One down, 93485763827563856 to go.
