When HP bought Palm on Wednesday, it got itself a powerful mobile operating system, two phones (plus whatever’s in the pipeline), numerous talented people, and a venerable brand. And it also scored fifteen years’ worth of mobile technology patents. Some of them resulted in iconic products. And some of them…well, didn’t. I’m sure Palm leveraged some of the ideas in the patents you’re about to see. But it also protected a bunch of concepts unlike anything that has ever carried the Palm name–so far.
