Oh, don't get me started on patents! There are parallels for sure, since the mechanism is there to encourage creativity by allowing the creator to profit from it.
When I was young, an electronics trade magazine published a series of articles about various circuit configurations and how they could be used. One month, they published a letter from a guy who explained that last month's configuration was covered by a patent that he owned, and that anyone using it had to license it from him. This set me thinking.
Some inventions are patented even when they're really quite obvious. As a thought experiment, suppose you made a device which, instead of having a method pre-programmed, it considered on boot-up all the possibilities, and calculated which one was the most effective, and then went on to use it for the duration of the power-on. All devices were to be sold powered off as a condition. In this case, if the patent holder tried to bring an action, they would be forced to admit that the device as sold did not contain the patent, and that because the device chose to use the patented method by itself, it could not be considered creative. (I'm assuming that the concepts of creative and automatic are complementary here.)
Would the patent holder be cheeky enough to require that the 'best method determining program' specifically exclude his method from the range of options? That would be quite a damning admission, and should draw attention to the injustice.
The parallel with this thread is here: suppose New English Teas goes ahead and uses one of those Canon cameras that does the effect automatically, and points it at a London Bus. They don't photoshop it at all, but use it as it comes out of the camera. Temple Island Collection did not create the scene, so New English Teas are not copying something that belongs to Temple Island Collection. All the creativity [sic] was performed automatically by the camera, so by the automatic/creative principle, it cannot be considered creative. All that is left is the idea of that kind of image, which would have to be more of a trademark dispute rather than anything else (e.g. if other tea companies tried to make their product look like New English Teas'). Doesn't this prove that the case went the wrong way?
And to further the patent parallel; are we to have a special image recognition software in the Canon cameras, like some image software
refuses to print banknotes, that pops up a warning if it detects an object that looks like a London bus, asking the user if they wish to continue to purchase rights to that from Temple Island Collection, or abort?
