Doesn't matter. You're trying to take ownership of an obvious idea. Your patent did not inspire anyone at Square, nor did anyone at Square learn how to perform this process by your patent. They don't owe you a cent. It is only by a shitty quirk of the system, which you are taking advantage of, that allows you to try to extort money out of them. You are part of the problem.
question is how do we distinguish between patents that "inspired" and those which did not?
Or does inspiring even matter - anyone can see the "inspiration" on Android from the release of the 1st iPhone (e.g. before and after designs) - yet this fact plus all of Apple's $billions were unable to stop/prevent Android from their clearly inspired copying.
Is it still considered a quirk when it's by design and it's the entire point of the system? If we're only talking about damages for when designs are copied (instead of independently developed), we're basically talking about trade secret misappropriation.
Patents are SUPPOSED to cover the case where someone else invents the same thing in parallel, independently. You might not like it, but that's a legal fact. Clearly, you have a different moral opinion of when someone should be able to enforce their patent rights.
