UK Patent Search: How to Check Existing Patents and Research Grants

Why Innovation Data Matters for Business Decisions

A technology company is evaluating an acquisition target. The target claims to have 'significant intellectual property' and 'strong innovation capabilities.' But how do you verify these claims objectively? The company's patent portfolio is registered with the UK Intellectual Property Office, but searching the IPO database requires navigating a complex interface designed for patent attorneys. Research grant history is scattered across UKRI's Gateway to Research, Innovate UK's project database, and Knowledge Transfer Partnership records. Trademark registrations are on yet another register.

Innovation data is public but fragmented. An investor performing due diligence on a company's R&D capabilities currently has to check four or five separate government databases, each with different search interfaces and data formats. A competitor analysing a rival's patent activity has to do the same. A research institution looking for industry partners with relevant expertise has to manually correlate patent filings with grant awards. None of these tasks is impossible, but all of them are time-consuming enough that they are often skipped or done superficially.

The Innovation Intelligence endpoint aggregates patent data from the UK Intellectual Property Office, trademark registrations, research grants from UKRI Gateway to Research, Knowledge Transfer Partnerships from Innovate UK, and R&D intensity benchmarks into a single API response. It accepts a company name, Companies House number, or topic keyword, and returns a comprehensive innovation profile with a proprietary Innovation Score.

For investors, this means objective evidence of innovation capability before committing capital. For R&D teams, it means landscape analysis that reveals who is filing patents in their technology area. For IP lawyers, it means efficient prior art searching and portfolio benchmarking. For university technology transfer offices, it means identifying industry partners with active research funding.

How to Search Patents and Research Grants

The quickest way to check a company's innovation profile is through our free Company Check tool, which includes patent and grant data alongside financial and officer information. For dedicated innovation analysis, the Innovation Intelligence API at /api/v1/innovation/{identifier} accepts a company name, Companies House number, or topic keyword.

When you pass a company identifier, the API returns that company's patent portfolio, trademark registrations, research grants, and KTP partnerships. When you pass a topic keyword (e.g., 'battery technology' or 'gene therapy'), it returns patents and grants matching that technology area, enabling landscape analysis rather than company-specific lookup.

The endpoint supports three depth levels. Summary depth costs 4 credits and returns the Innovation Score, patent count, and grant count. Standard depth costs 12 credits and adds individual patent titles, filing dates, status, trademark details, and research project summaries. Full depth costs 24 credits and includes patent classifications (IPC codes), grant amounts, KTP details, and R&D intensity benchmarks against sector averages.

The government alternative involves searching three separate databases. The UK IPO's Ipsum service provides patent search but with a technical interface designed for patent attorneys. UKRI's Gateway to Research covers publicly funded research projects but does not include patent data. The Companies House filing history may mention R&D in annual reports but provides no structured innovation data. The API normalises all of these into a single coherent response.

Understanding UK Patents and Trademarks

A patent grants the holder a time-limited monopoly on an invention — typically 20 years from the filing date. In the UK, patents are granted by the Intellectual Property Office after examination to verify that the invention is new, involves an inventive step, and is capable of industrial application. The API returns patent applications (filed but not yet granted) and granted patents, with filing dates, titles, current status, and IPC (International Patent Classification) codes.

The distinction between applications and grants matters. A company with 50 patent applications but only 5 grants has a very different IP position from one with 30 grants. Applications take 2-5 years to process, so a high application-to-grant ratio may indicate either recent filing activity (applications not yet examined) or weak applications (likely to be refused). The API provides both counts, enabling this analysis.

Trademarks protect brand names, logos, and distinctive signs. UK trademarks are registered through the IPO and last 10 years, renewable indefinitely. The API returns registered and pending trademarks associated with a company, including the classes of goods or services covered. Trademark data is particularly useful for brand protection analysis — seeing whether a company has protected its brand across relevant product categories.

For topic-based searches, the patent data reveals the innovation landscape in a specific technology area. Searching for 'hydrogen fuel cell' returns recent patent filings from all applicants, showing which companies and universities are active in the space. This landscape view is valuable for R&D strategy — identifying white spaces where few patents exist (indicating opportunity) and crowded areas where freedom to operate may be constrained.

Research Grants and Knowledge Transfer Partnerships

Publicly funded research is a strong signal of innovation capability. Companies and universities that win competitive UKRI grants have passed rigorous peer review — the success rate for many funding schemes is below 25%. The API returns research grants linked to the queried company or topic, including the funding body, project title, value, start and end dates, and research partners.

UKRI (UK Research and Innovation) encompasses seven research councils, Innovate UK, and Research England. Innovate UK specifically funds business-led innovation — grants that require commercial exploitation plans and often involve collaboration between companies and research institutions. A company with a history of Innovate UK grants has demonstrated the ability to articulate commercial innovation plans that satisfy expert review panels.

Knowledge Transfer Partnerships (KTPs) are structured collaborations between businesses and universities, where a recent graduate (the KTP Associate) works in the business on a specific innovation project under academic supervision. KTPs last 12-36 months and are partly funded by Innovate UK. The API returns KTP partnerships associated with a company, which indicate active knowledge exchange with academic research.

For investors, grant history is evidence of both innovation capability and external validation. A company that has won three Innovate UK grants totalling £1.5 million has been assessed as innovation-capable by independent experts three separate times. This is more informative than self-reported R&D claims in marketing materials.

For universities, the grant and KTP data helps identify industry partners for future collaborations. A company with an active KTP and two completed Innovate UK grants in a relevant technology area is a proven collaborative partner — reducing the risk of new partnership proposals.

The Innovation Score Explained

The Innovation Score is a proprietary rating from 0 to 100 that quantifies a company's innovation activity relative to its sector. Higher scores indicate stronger innovation capability, as measured by observable public data.

The score is calculated from five weighted factors. Patent portfolio accounts for 30% — the number of granted patents and pending applications, weighted by recency. Recent filings count more than decade-old patents because they indicate current R&D activity. A company with 15 patents filed in the last 3 years scores higher than one with 30 patents all filed before 2015.

Research grant activity contributes 25%. This measures the value and frequency of competitively won research grants from UKRI, Innovate UK, and EU Horizon (UK-eligible). Winning grants demonstrates that the company's research plans have been validated by expert peer review.

Trademark registrations account for 15%. Active trademarks across multiple classes indicate brand investment and commercial exploitation of innovation. A company that patents a technology but does not trademark the commercial product may have weaker commercialisation intent.

KTP partnerships contribute 15%. Active or recent KTPs indicate structured knowledge exchange with universities, which correlates with sustained innovation over time rather than one-off inventions.

R&D intensity versus sector average provides the final 15%. This compares the company's observable innovation activity against others in the same SIC sector, adjusting for company size. A small company with 5 patents in a sector where the average is 2 scores well on this factor; the same 5 patents in a sector where competitors have 50 would score poorly.

Score bands: 0-25 indicates Limited innovation activity, 26-50 is Below Average, 51-75 is Good (active innovation programme), and 76-100 is Excellent (innovation leader in sector).

Practical Applications for Innovation Data

For investors and M&A teams, the Innovation Score provides an objective benchmark during due diligence. Rather than relying on management's claims about R&D capability, you can see the patent portfolio, grant history, and relative innovation intensity in hard data. Two acquisition targets with similar revenue but Innovation Scores of 72 and 23 present very different value propositions.

For R&D teams conducting competitive analysis, topic-based searches reveal who is filing patents in adjacent technology areas. If your company is developing a new manufacturing process, a landscape search reveals which competitors and universities have recently filed in the same space — and where there are gaps that your IP strategy could exploit.

For IP lawyers, the API supports prior art searching and freedom-to-operate analysis. Instead of searching the IPO's technical interface for each relevant classification, a topic query returns relevant patents across multiple classes, providing a starting point for detailed legal analysis.

For university technology transfer offices, the data identifies companies with demonstrated innovation activity in specific research areas. When a professor develops a new material with commercial applications, the TTO can search for companies with patents and grants in that material's application area — building a shortlist of potential licensees or collaboration partners.

For government economic development agencies, the Innovation Score enables mapping of innovation clusters and identifying regions where innovation support programmes would have the greatest impact. At 12 credits per standard call, profiling every company in a sector or region is practical and affordable.
