I have an Idea/Potential Patent, but someone else has a similar patent out. Our inventions are substantially different in design. One of their claims is very very general and seems to exclude an entire market. Are you allowed to list a non-descriptive function of your product as a claim? For example, here's a similar claim if their invention were a solar panel:
Any device using silicone technology to generate power for electronic consumption.
Is this type of sweeping claim valid? Do I have a new patent if I use a new and different type of silicone technology?
