Licensing
You can use someone else's patent if they have granted you a licence to do so.
Some patents are endorsed in the register of patents with a licence of right entry. This means that anyone has a right to a licence under that patent.
The terms of any licence are entirely a matter between you and the licensor, and we do not have any powers to investigate the validity of a licence unless you cannot agree about the terms under a licence of right.
You or the licensor should register the licence with us and we will record it in the register of patents.
Fill in Form 21
To register a licence or cancellation of a licence you need to fill in form 21. There is no charge for this.

You do not need a licence for a patent that is not valid. A validity search can help you to check if a patent is valid.
