So, answer me this:
If you think "pinch-to-zoom on a mobile device with touch screen" is a reasonable thing to patent so that nobody except Apple can use it on a smartphone, then you would have also had have no problem if:
- Someone patented "tabbed browsing" on a desktop computer[1] and nobody could sell a browser with tabs on a desktop platform
- Someone patented the pull-down list-select control on a desktop computer, and now everyone writing a GUI for the desktop platform would have to come up with their own variation of a list-select control that is sufficiently different from the patented one.
I could come up with many more similar examples, but I'm not at all sure how/whether the above two hit the mark as an analogy for the trick Apple just pulled (because I find all three situations absurd).
Hm, now this makes me wonder, Ableton Live has this truly brilliant way of navigating a waveform/timeline effortlessly to anywhere in both large and tiny zoom scales, it's incredibly efficient and quite intuitive, and I've (so far) never seen any audio editing software that has something quite like it. I wonder if they patented it? It is way more innovative and non-obvious than the "pinch-to-zoom" that Apple grabbed. Also there are quite a number of different but quite obvious ways to navigate a waveform on the same input devices (desktop+mouse, usually) unlike "pinch-to-zoom", which is really the most obvious gesture for zooming on a touch-display.
Because I was thinking of maybe one day coding up a very simple waveform editor, and I wouldn't be satisfied until I at least tried to implement that mode of navigation. Of course as long as I don't sell it, I'm safe from patents right?
[1] just adding that because as far as I'm aware these software/design patents only work because they're coupled to a specific piece of hardware (in the US, that is. for now, thankfully it works a bit differently in the EU)
