Another requirement is non-obviousness - 35 USC 103. Under this requirement, you can show that a patent claim is obvious by showing that a combination of prior art references together teach each and every element in the claim and that they could be reasonably combined. So, if the Claim is A+B+C+D and one reference shows A+B and another shows C+D and they could be combined, that shows that the Claim is obvious.
So, for example, if you can find other references that show a hand-held device, continuous movement of an image, and unlocking a device, those combined with this may be enough to show that the Claim is obvious. That should be pretty easy to find.
Do they all have to be in the same medium? For example, could a sliding dead bolt plus sliding an icon on a hand held device be used to demonstrate obviousness?
Personally, while I realize the importance of the patent system I think it has gotten a bit out of hand. Rather than be a way to protect ideas they've become an offensive weapon against competitors; and while they may have always been used as such the current practice of adapting physical models to a digital world has made things worse, IMHO. I am not convinced that allowing patents on concepts that already exist and are in widespread use is a good idea.
Unfortunately I am at a loss as how to fix it. Perhaps rather than jury trials we should establish panels of legal and technical experts that would hear claims and the loser pays the fees; and if the patent holder loses the patent becomes invalid. Maybe adding a requirement that the patent actually be used in products or licensed within the first X years of issue or the patent becomes invalid. Beefing up the USPTO so they could do more in depth reviews would help as well.
Finally, I'm not sure juries could really understand the technical details of a patent to be able to assess prior art and obviousness. I say that because pif my experiences on a jury. We had a simple drunk driving case and the defense argued because roadside sobriety tests have a 30% false positive rate there was reasonable doubt as to guilt. Some of the jurors were buying that until I explained he failed 10 tests in a row and the odds of all of those being false positives were astoundingly low. Ultimately we convicted him; but if no one on the jury understood basic probability he may have walked. If jurors lack basic technical literacy I wonder how they can follow complex patent claims and be swayed by the best argument or emotions or who makes the most persuasive argument in the jury room.
