Re: This is ridiculous
I've got a patent for something that has no reference to the working model in the patent application. There is a working model, just that it isn't mentioned in the patent.
If you insist that something can only be patented if you have a working model then you skew the patent system in favour of organisations with big resources to build those models, and against the individuals that actually have the idea.
If you create an algorithm for something and can show the mathematics and proof of it, why should you be excluded from protecting that idea simply because you have not got, say, the processing power required to demonstrate it on?
