"Apple Has A Patent On ‘Slide To Unlock’"
Apparently Apple has a patent on this:
Slide to unlock is an excellent idea. Indeed, it’s difficult to see how you could implement a multi-touch smartphone without doing something along these lines. Which is why Android has the functionally equivalent, though in my view somewhat superior, pattern unlock feature. Jerry Hildenbrand seems to think that what’s ridiculous about this patent is that it arguably existed already when Apple was granted the patent. But the real problem here is that it’s contrary to the public interest to ban copying this kind of thing. We want to live in a world where useful new features are rolled out, and then bosses say “we need to find a way to implement that on our product.”
