Wonder who owns the patents to this kinda technology

• marcus 19y ago
  I think most patents on this technology have expired with the possible exception of multi-touch.
  • apgwoz 19y ago
    this technically isn't "touch" though, so you should be OK. :)
    • marcus 19y ago
      True, but it all depends on the way the individual claims are written in the patents governing multi-touch systems. If they have separated the claims for determining touch points and for the using different touch points to control zoom for example it might still be a problem, need to read the patent claims carefully to be sure.

        Still amazes me you can get patents on such things. If you touch a screen with 2 fingers, and draw them outwards or inwards, what other thing could they conceivably control other than zoom? Amazing :)

          How about deforming?

          Porn.

      Also, generally you can't patent ideas like "multitouch" but rather processes or methods of implementing an idea. Not sure if there's any patents on IR-based input like this, but a quick search didn't turn anything up.
