Hi, after nearly two years of research and discovery, I think I may be close to creating a workable prototype of the product I'm trying to develop. My idea will require a particular type of adhesive closure that I have found on a product that is available from a company in Taiwan. The owner of the existing product has a patent for the adhesive closure, but he is using it for purposes that are no where near the purpose I would use it for with my product. My questions: -Can I obtain a patent on a product if it is based on(or built from)an existing patented product? -Would it be considered a "new use" patent?
-Would I have to get permission from the current patent owner first since it truly is his unique patented technology that would make my product possible?
-Can I just order his product as raw material and use it to create my product?
Thanks in advance.
