Patent Box

The Patent Box tax incentive allows companies to apply a lower rate of Corporation Tax to profits from patented technology.

Our partner Hugh Dunlop explains the Patent Box tax incentive and the necessary considerations when making a claim. 




What is Patent Box?


The UK Government legislation on the Patent Box tax incentive came into effect in April 2013.


The incentive is a reduced corporation tax rate of 10% on net profits attributed to patents (after certain deductions), with the aim of encouraging development of patentable technology in the UK. This compares highly favourably with the current main corporation tax rate of 25%.


All revenue from a UK company can count towards your Patent Box application and any patent in a qualifying patent office can count. UK national patents attract low official fees, so are a cheap way to qualify for the Patent Box without the need to file in other countries.


Qualification for Patent Box regime


You may qualify for Patent Box through legal ownership of the patent and/or exclusive license from the patent owner. Patents acquired from or developed in collaboration with other companies may also qualify.


It can be a UK or European patent, or a patent granted by another EEA country with similar patentability criteria, such as a German patent. US patents do not qualify, as they may cover inventions such as business methods that would not be patentable in the UK.


The tax incentive is not limited to profits derived from countries where the patent is granted; instead, the existence of a qualifying patent is taken as an indication that the technology meets the requirements of technicality, novelty and inventive step.


Pending patent applications do not qualify, but once a patent is granted, profits arising up to 6 years before grant may qualify for the reduced tax rate.


The company must have undertaken ‘qualifying development’, by making a significant contribution to the creation or development of the invention claimed in the patent, or a product incorporating the patented invention; mere ownership of the patent is not enough. A company can also qualify if it actively manages the portfolio of patent rights for another company in the same group that has undertaken the ‘qualifying development’.


Stages in calculating tax relief


There are three stages to calculating tax relief:


  • Identifying qualifying patents or patent rights known as the 'relevant IP income'
  • Qualifying residual profit
  • Removing marketing assets return


1. Identifying qualifying patents

Identifying qualifying patents or patent rights ('relevant IP income') means calculating the basic profit attributed to qualifying income.


2. Qualifying residual profit

You can calculate the qualifying residual profit by deducting routine profit the the Treasury expects that you would have made without benefitting from patented technology. The Treasury assumes a routine return of 10% on expenses. 


3. Removing marketing assets return

Marketing assets return refers to any profits attributed to brands and marketing that do not depend on innovation. Once these are removed you pro-rate patent and non-patent profit to give the patent box benefit.

Patent Box timeline


0 months: Filing/priority date (eg. UK application) 


12 months: File PCT/national application claiming 'priority' from UK application


18 months: Publication date


(30-31 months: Enter PCT national phase in countries of interest - optional)


3-4.5 years: Grant of UK and other National Applications 

(earlier if the Green Channel applies)


Tips for applying for Patent Box


Patents may be filed purely to gain a tax benefit: there is no need to enforce the patents against competitors.


Before applying you should check whether any of your existing products already contain qualifying patents or employ qualifying patents in their production. If not, you should consider whether any patented ideas could be legitimately included to enhance production processes or product functionality. 


When developing a new prodcut it is equally important to consider what IP rights you may have. Patents or other IP rights may be available to you.
