I recently acquired some patents from a bankruptcy estate and would like to know if I can cancel or renegotiate any license agreements that were in place by the original inventor or patent owner with licensees? The company that owned the patents actually produced the product and I have found a very large company who appears to be selling the same product and using the trademark name as well. Second question is, if it was a non-exclusive or exclusive agreement am I entitled to royalties fees?
Thanks
