Why SMEs Receive Just 5% of £2bn Tax Relief Under the Patent Box Scheme UK

Published by Nida Umair posted in Resources on 17 December 2025

The Patent Box Scheme UK was introduced to encourage innovation by offering a reduced corporation tax rate of just 10% on profits derived from patented products or processes. This initiative is designed to incentivise businesses to develop and commercialise their intellectual property (IP) in the UK, contributing to the country’s technological and scientific advancements. However, despite the scheme’s aim to support businesses of all sizes, a significant disparity exists in how tax relief is distributed. While large corporations claim the bulk of the relief, small and medium-sized enterprises (SMEs) are receiving only a small fraction of the total available benefit. This imbalance raises concerns about the accessibility of the Patent Box for SMEs, limiting their potential to thrive and innovate.

As the Patent Box scheme continues to evolve, it is crucial for SMEs to better understand and navigate the application process, ensuring they can fully capitalise on this valuable tax relief.

What is the Patent Box Scheme?

The Patent Box is a tax relief scheme introduced by the UK government to support businesses that develop and profit from patented technologies. Companies that meet certain criteria can apply a reduced tax rate on the profits derived from their patents, which can result in substantial savings for eligible businesses. The scheme was designed to help stimulate investment in R&D, particularly in sectors such as technology, manufacturing, and pharmaceuticals.

How Big is the Discrepancy?

While the total tax relief claimed under the Patent Box scheme has increased, SMEs have not seen proportional benefits. According to the most recent data, large businesses receive the lion’s share of the relief, claiming a massive 95% of the total. In contrast, SMEs—those that typically struggle to access large-scale R&D funding—only claim 5% of the total relief, with small companies alone receiving just 1%.

This uneven distribution highlights a key issue: the Patent Box for SMEs is predominantly benefiting large corporations that have the resources to invest in significant IP portfolios. These businesses tend to generate higher profits from their patents, which is why they claim the largest portion of the relief.

The Slow Uptake by SMEs

While the number of businesses using the Patent Box scheme has gradually increased, the rate of growth remains slow. In fact, the number of companies claiming relief has been stagnating since 2018-19, showing that smaller businesses are not fully taking advantage of the scheme. Although the scheme’s uptake among large businesses has been steady, the small and medium sectors have struggled to see substantial participation, despite their potential eligibility.

This lack of engagement could be due to several factors:

  • Lack of Awareness: Many small businesses may not be aware of the Patent Box or its benefits.
  • Complex Application Process: Applying for the relief can be a complicated process that may seem out of reach for smaller companies without in-house tax experts.
  • Eligibility Criteria: Meeting the eligibility requirements can be challenging for small businesses, particularly when it comes to demonstrating how profits are linked to patented products or processes.

These challenges mean that many smaller businesses miss out on valuable tax relief for patented products that could otherwise support growth and reinvestment.

Why Large Businesses Dominate the Patent Box Scheme UK

The key reason that large businesses are the primary beneficiaries of the Patent Box is their ability to generate substantial profits from their intellectual property. Larger companies often have the resources to develop and protect multiple patents, which in turn generates high profits subject to the tax relief. Smaller companies, in contrast, tend to have fewer patents and lower profits associated with their IP, limiting the amount of relief they can claim.

Moreover, large firms typically have dedicated teams to handle tax claims and ensure compliance with the Patent Box requirements, making it easier for them to navigate the complex process. In comparison, SMEs often lack the necessary expertise to manage this process.

How Can SMEs Benefit from the Patent Box?

Despite the challenges, small businesses can still benefit from the Patent Box scheme if they follow a few key steps:

  • Evaluate Your IP Portfolio: SMEs should review their intellectual property portfolio to assess whether they hold patents that could be eligible for relief.
  • Track Profits from Patented Products: It’s important to maintain accurate records of how profits are derived from patented products or processes. This can be crucial for demonstrating eligibility.
  • Seek Professional Guidance: Given the complexity of the scheme, working with tax experts can help ensure that SMEs are maximising their potential relief.

What Industries Benefit Most from the Patent Box?

The Patent Box scheme is particularly beneficial to industries that rely heavily on innovation and technological advancement. The manufacturing sector, for example, accounts for a significant portion of claims, as many manufacturers protect their innovations through patents. Other sectors benefiting from the scheme include information and communication technologies and wholesale and retail trade.

Manufacturers and tech companies are often the largest users of the Patent Box, as they are more likely to have extensive IP portfolios and to invest heavily in R&D. Smaller businesses in these sectors, however, may find it more difficult to secure the full benefits of the scheme due to the sheer scale of investment required.

Regional Breakdown of Claims

Geographically, the majority of Patent Box claims come from businesses based in London and the East of England, reflecting the concentration of large businesses in this area. Other regions, such as the Southeast and Northwest, contribute a smaller portion of the total claims. This regional disparity suggests that businesses in certain areas may have more access to resources or support, making it easier for them to claim the relief.
