Patent Box 101

Reduce your corporation tax to 10% with InnoFund

At InnoFund, we help businesses like yours turn intellectual property into real financial advantage.If you own or have exclusive rights to a qualifying patent, you could significantly reduce your corporation tax bill through the UK’s Patent Box regime.

What is the Patent Box?

The Patent Box is a government incentive designed to encourage companies to retain and commercialise patents in the UK. Under the scheme, profits earned from patented inventions are taxed at a reduced corporation tax rate of 10% – compared to the standard 25% rate. By taking advantage of Patent Box, you can reinvest those tax savings directly back into innovation and growth.

What patents are eligible for Patent Box?

For patents to be eligible for the UK Patent Box regime they must be granted by UK IPO, European PO or any of the following countries: Austria, Bulgaria, Czech Republic, Denmark, Estonia, Finland, Germany, Hungary, Poland, and Portugal.

What income qualifies?

  • Sales of patented products or products incorporating a patented component
  • Licensing or royalty fees for patented technology
  • Sales of patented processes or services using patented inventions
  • Compensation from infringement proceedings/insurance

Who can benefit?

There are a number of qualifying criteria your business must meet in order to claim relief,
including:

  • Liable to corporation tax
  • Making profits from the patent
  • Having an exclusive licence for, or owning, the patent
  • As part of a group company that meets the active ownership condition
  • Meeting the qualifying development condition

How much can you save?

With corporation tax currently set at 19-25%, reducing the rate to 10% on qualifying profits
could represent substantial savings. The more successful your patented innovation, the
greater the benefit.

For example, a higher rate tax payer with £1,000,000 in IP profits could save £150,000.00 in corporation tax.

Calculating the Nexus R&D Fraction

Since 1 July 2021, all Patent Box claims must demonstrate a clear connection between qualifying R&D activities and the patented innovation. This is done by calculating an R&D fraction for each relevant patent or patented process, applied to the associated income streams.

The purpose of this requirement is to ensure that only companies that can prove a direct link – or nexus – between their R&D efforts and the resulting tax benefit can access the reduced Patent Box tax rate.

The R&D fraction is a figure between 0 and 1. It starts at 1 but may be reduced if the company has incurred costs to acquire the patent (e.g., purchasing IP rights) or has outsourced R&D to connected parties such as group companies or related subcontractors.

How does Patent Box work?

To benefit, you’ll need to:
01 Own or exclusively license

a qualifying patent granted by the UK Intellectual Property Office (IPO), European Patent Office (EPO) or certain other jurisdictions.

02 Actively develop

the patented innovation or have played a significant role in its creation.

03 Make an election

into Patent Box within two years of the end of the relevant accounting period.

Once elected, your eligible profits will be subject to the reduced 10% corporation tax rate.

InnoFund takes a holistic view on your innovation, together we build a strategy that combines both schemes to maximise your return.

Frequently Asked Questions

Can we claim if we don’t manufacture products ourselves?
You may qualify. If you hold a patent and grant another company an exclusive licence to commercially exploit it, you can still claim relief based on the royalties or licence fees you receive. However, if your company didn’t develop the patented invention itself (i.e., you didn’t contribute to its R&D), you will not be eligible for Patent Box relief
If your company is part of a group, you must actively own the patented invention and play a significant role in managing the portfolio of qualifying patents to access Patent Box relief.When IP is shared, an exclusive licence must be in place between the IP owner and the company commercially exploiting the patent for the relief to apply.
Yes. If your company licenses out its patent and receives licence fees or royalties, this income is considered qualifying IP income under Patent Box. Even if you aren’t directly exploiting the patent, licensing arrangements can still make you eligible for the reduced tax rate.

An exclusive licence is a legal agreement where the patent holder grants another party the exclusive rights to exploit the IP, instead of doing so themselves. This typically includes:

  • The right to one or more key patent rights, excluding all others, within specific
    countries or territories.
  • The right to pursue legal action for infringement independently and to retain all, or
    most, of any damages awarded.

In simple terms, it is a formal agreement between the IP owner and the licensee, granting the licensee exclusive rights to use the IP without risk of infringement.
