We help innovative companies to maximise their tax savings through the UK’s Patent Box regime.

What is Patent Box Tax Relief?

The Patent Box is a government initiative designed to reward businesses that commercialise patented innovations in the UK. Profits attributed to patented inventions may qualify for a reduced corporation tax rate of 10%, compared to the standard 25% rate.

Patent Box encourages companies to develop, retain, and exploit IP in the UK, boosting innovation and reinvestment potential.

Why choose InnoFund for Patent Box claims?

Maximised claim value, compliance and efficiency

At InnoFund, we specialise in simplifying complex tax incentives. As a patent box tax specialist we use IP strategists, engineers, and innovation consultants to help you realise the true ROI of your intellectual property.

As a patent box tax specialist InnoFund can often improve previous work done by accountants and other specialists by:

Accurate Identification of Relevant IP Income

Most accountants apply a basic apportionment approach to isolate income from patented products. A Patent Box speciali, however:

  • Dissects product lines to isolate only the income attributable to patented components or processes.
  • Identifies bundled IP revenue (e.g., licensing, embedded tech, spare parts) that might be missed in a standard claim.
  • Optimises the use of the streaming method or standard method, depending on the business structure and available data.


  • Compliance gains

    Increased claim accuracy and often a higher qualifying income base.

Structuring the Claim for Maximum Tax Efficiency

Accountants may treat Patent Box as a post-R&D relief exercise. A Patent Box specialist, however:

  • Integrates Patent Box with R&D tax relief for long-term strategic gains.
  • Times patent filings and elections to align with commercialisation phases and tax planning.
  • Advises on group structures or IP ownership strategies to ensure tax is minimised across all entities.


✅ Maximised Claim

Better long-term planning and reduced effective tax rates across multiple years.

Clarifying and Defending Nexus Calculations

The Nexus fraction is a key part of the new regime (post-2016), linking Patent Box benefits to R&D performed by the claimant. Specialists:

  • Provide detailed R&D traceability to ensure Nexus compliance
  • Maximise the qualifying fraction by documenting internal vs outsourced R&D spend and IP development pathways.
  • Work with R&D teams to ensure accurate tracking of development expenditure and IP linkages.


✅ Maximised Claim:

Higher Nexus fraction means that a greater portion of income eligible for reduced tax.

Bridging the Knowledge Gap Between IP and Tax

Accountants aren’t typically trained in patent law or innovation strategy. A specialist can:

  • Assess whether existing products/processes can be patented, even retrospectively.
  • Work with engineers or design teams to adapt existing IP to fit Patent Box eligibility.
  • Help coordinate with patent attorneys to ensure claims align with commercial realities..


✅ Maximised Claim:

More products covered under valid patents with a broader scope for relief and increase in tax benefit.
