Wait a sec, aren’t patents created to avoid missunderstood between companies (commercial ones)? I mean, lets say a company patented Thumbnail views, and you create a nice website using that thumbnail size, is it possible that the company searched you and asks to pay 15 million dollar? Or is it, another company used thumbnails for a digital camera to display images you made, and have to pay patents for that?
The reason why I ask, is that Sony pays now 15 million dollar to use thumbnails on cameras, dvd players and some more. But how the hack does a normal citizen pay 15 million dollar to display his renderd images on a website?
For now I’m not sure if these things count for commercial companies and/or everyone else. If it’s commercial only, well the Blender Foundation isn’t commercial, isn’t selling it’s software, only the guides. Besides this, there are rules for patents, (dutch: octrooi), and can be found one some websites here. But I think we aren’t in harmfull way if we still keep blender free, when it comes to pay for blender, then companies begin to ask payments for the stuff we put in that’s them.
But reply when I’m wrong, well I hope I’m not wrong. I also gave my vote for no patent law in europe a few months ago. I think everyone should do, but on another side, I think it won’t come that far. Because here in europe the governements of different countries are promoting opensource stuff by having (like the netherlands) there tax pay software in opensource and crossplatform, (the way citizen have to pay there taxes or else that’s related to it) 
And even better, the governement also gives money to people that develope freeware opensource stuff, not sure how that’s called in english, but it’s something that schools also get for teaching childeren stuff, subsition or something. So why invest money in such projects if they want the patent law? I think that the companies want that law, but the governement isn’t sure about the idea, I hope the governement is still more powerfull then those companies. Besides that I also thougt it’s violating the law of freedom. If a citizen have to pay those patents too, you are in some kind of way not allowed to make your own software, websites, or another artwork, because someone somewhere has patented it. Isn’t that comminisme? whitout permission or payement no publishing or creating things? That what communisme is, not democrasy. If there’s a way to catch those fortunistic companies, then they are srewed.
