Patent Box

Innovation Incentives - Patent Box:

The Patent Box regime allows companies to apply a reduced rate of Corporation Tax to profits earned from patented inventions and certain other innovations. It’s a powerful incentive designed to encourage UK-based innovation by significantly reducing the tax burden on commercialised intellectual property.

At Westlock Partners, we help companies unlock the full benefits of the Patent Box – from assessing eligibility through to calculating the relief and preparing the required documentation to support your claim.

What Is Patent Box?

Patent Box enables companies to apply a lower 10% Corporation Tax rate to profits attributed to patented products, processes, or technologies. This is a substantial reduction compared to the standard 25% rate.

Qualifying income includes:

  • Sales of patented products (or products incorporating a patented component)

  • Patent royalties and licensing income

  • Sale of patents or patent rights

  • Damages or compensation from patent infringement cases

  • Embedded IP income within broader technology or software platforms

Who Can Claim?

To benefit from Patent Box, your company must:

  • Be liable to UK Corporation Tax

  • Own or exclusively license-in qualifying patents granted by the UKIPO, EPO, or certain EEA countries

  • Have undertaken qualifying development on the patented invention

  • Be actively exploiting the patent (e.g., manufacturing, selling, licensing, etc.)

Patent Box often goes hand-in-hand with R&D tax relief, but requires a separate, technically robust calculation and election process.

How We Can Help

Patent Box calculations can be complex, involving not only the identification of qualifying IP but also the disaggregation of income streams and detailed profit apportionment. Our team provides:

  • Strategic assessment of eligibility

  • Patent mapping and income stream identification

  • Nexus fraction calculations

  • HMRC election submission support

  • Integration with your R&D tax relief claims
