I know this was a jury trial and perhaps the Appellate Cts can reverse the far reach of the decision. I think a trier of fact has to consider a natural progression of products that require human human movement, appendages and brains. I don't see any other way the technology could have gone to stretch a screen than to unpinch or double tap. Would triple tapping be a different patent, what about using your elbows or your tongue. Maybe voice stretching or eye crossing. I think it's getting ridiculous that generic movements that are inevitable to be part of a product line can be patentable.
Had this discussion with a guy yesterday. He brought up the sentence, "It's the best of times, it's the worst of times" and how that is copyrightable. But, no one is destined to create that sentence that's attributed to Dickens. Yet, many of us have thought about stretching a piece of paper or a screen, even if it were nonesense day dreaming. How many daydreams were there with "It's the best of times, it's the worst of times" before Dickens coined the phrase. Actually, taken by itself without the rest of The Tale Of Two Cities, maybe that sentence alone cannot be copyrighted. I don't know know, I'm not a lawyer, It's certainly close to, "There are good times and bad times," which millions of people have said.
There aren't endless combinations for human finger movements to allow us tothink that the guy who invented it, should own it. However, the mechanics, electronics of the screen and software that accepts that movement, maybe that should be patentable but only if everything is the same. Change how it works or the software and that should require a new patent or no patent. I just don't like it.
