I have not done this myself, but know this from a guy who used to work there: They have a portal where you can submit ideas, which they will evaluate and offer to acquire if they like. Of course, they say "ideas", but they're really looking for well developed technologies that haven't been patented yet. I imagine they want fairly detailed technical submissions, maybe a published paper. Something along the lines of "do X on a computer" probably won't do as well. Edit: I don't know how they actually "acquire" it, but I'm guessing they offer payment and a portion of future royalties for exclusive rights. But you do bring up a good point - since there is no patent, the scope of the rights being acquired is legally undefined.
