Co-ownership (patent) - Intellectual Property Law

Co-ownership, or ‘joint ownership’, is where multiple individuals or companies jointly own a patent or patent application. Unless there is an agreement to the contrary, the default arrangment would be to have equal shares in the patent. Co-ownership entitles each party to work the invention without infringing the rights of the other parties. However, consent of all co-owners is needed to amend the specification of the patent, apply for the patent to be revoked, or to the grant of a licence or the assignment or mortgage of a share.
