Brand new here. I was approached for the first time by a company last week to license my patent. They sent me a licensing agreement, but I'm very skeptical because this is extremely new to me. I was offered a 15% of net proceeds with a one time payment of $7,000 to them. He told me they charge only those who have not been already in the market selling their product. Even me being brand new like I stated, this doesn't sound right to me at all. If someone wants to license my patent, shouldn't they be paying me? Any insight would be truly appreciated.
