I have a contract with a company to enhance my software. The contract states that my company owns all of the IP, Trade Secrets, know-how, drawings, etc of the original and add-on software as outlined in the Agreement. We did the add-ons to my software. We delivered the software and source code to the company. We never got paid. Now the company has filed a patent on my IP and received a patent.
Can I get the patent changed to reflect that my company owns the patent and is the inventor as well?
