I wanted to write a small Rapid Serial Visual Presentation (RSVP) program for my mobile device but I realized that there are some patent issues associated with that technique (exhibit 1 and exhibit 2).
Can I write such program and try to make money with it? Would it be legal to give such program for free?
the devil is in the details.
I’d suggest you write down what your program will do – in a more detailed way than ‘it does RSVP’.
Print out the patents appropriate, go through the claims made in the paents and see if you are doing what they’re claiming. I don’t think they’re claiming a patent on RSVP, just on certain ways of using it.
Make your own judgement call on whether it is worth continuing, if so, consult a lawyer that is an expert in that area of law before going further.
