Who Needs To Sign An IP Assignment In The UK?
The agreement should be signed by the current IP owner as assignor and the intended new owner as assignee. In many transactions, additional signatures or consents may be needed from inventors, authors, employees, consultants, joint owners, insolvency office-holders, funders, universities, trustees or licensors. For UK patents, trade marks and registered designs, identifying the exact legal owner and recording the transfer with the relevant registry is often essential to avoid enforcement and priority problems.
What Party Details Should An IP Assignment Capture?
For each party, capture full legal name, address, company or charity number where relevant, jurisdiction of incorporation, representative capacity and signing authority. For individuals, include residential or service address and any employer or consultancy context. For companies and LLPs, check Companies House details and board or member authority. For charities, public bodies and universities, check constitutional powers, delegated authority and any consent requirements.
How Should An IP Assignment Be Executed Under English Law?
Most corporate parties sign through authorised signatories or by deed where needed. Companies commonly execute under section 44 of the Companies Act 2006 by two authorised signatories or one director in the presence of a witness. Individuals usually sign with a witness if the assignment is executed as a deed. Some IP transfers have statutory writing and signature requirements, including assignments of copyright, patents, trade marks and registered designs.
What Authority Checks Reduce Assignment Risk?
- Check ownership first: confirm the chain of title from creators, employers, contractors and previous owners.
- Check capacity: verify that the party exists, is not dissolved, insolvent or acting outside its powers.
- Check representative authority: ask for board minutes, powers of attorney, delegated authority or trustee resolutions where appropriate.
- Check third-party restrictions: review licences, security interests, collaboration agreements, grant terms, university policies and funder rights before signing.
- Check registration steps: registered IP assignments should be recorded promptly with the UK Intellectual Property Office where applicable.
