Patent Box: relevant IP profits: relevant IP income: non-medical use claims

A patent that contains a product claim and a claim to a method of using that product will be protecting a new product. In this instance income arising from the sale of the product would fall under Head 1 income (S357CC(2)). But if a patent only includes a claim protecting a particular use of a product (that is, a method claim), income arising from the sale of the product would not fall under Head 1 income because the qualifying IP right is not in respect of the product. Instead the company will need to use the notional royalty provisions (S357CD, CIRD220250). Where the company also sells the product for a different use that is not covered by a patent, the income derived from that unpatented use will not be relevant IP income or a percentage of IP-derived income.


Company X holds a patent over the use of a lifting device for lifting a piece of furniture. It sells the lifting device for the purposes of lifting furniture and also for the purposes of lifting cars. It does not hold a patent over the lifting device itself so it brings in an appropriate percentage of its IP-derived income from sales of the lifting device for lifting furniture (but not for cars) using the notional royalty provisions.
