British inventors are filing patents again — but most are walking away from them
New Intellectual Property Office figures show UK patent applications at a ten-year high, driven almost entirely by people filing without professional help. Fewer than one in sixteen of those applications is likely to succeed. In France, where individual inventors still account for nearly a fifth of all filings, the picture looks very different.
Official statistics published by the UK Intellectual Property Office on 30 July show patent applications rose 19.8% in 2025 to 22,701 — the highest figure for a decade. Applications from UK-based applicants jumped 39.4% to more than 15,400, lifting the domestic share of filings to 68%, well above the 55% to 60% range of recent years.
At first glance, this looks like a national revival in invention. The detail tells a more difficult story.
Analysis of the IPO’s data by the patent profession shows the entire increase came from applicants filing without a patent attorney. Unrepresented filings reached 6,581 in 2025, a rise of 260% in a single year, taking them from 12.4% of all UK patent filings in 2024 to 29% in 2025. Filings made through patent attorneys actually fell by 3%.
This surge directly correlates with the rise of generative AI. The analysis indicates a 92% correlation between the number of weekly active users of the leading AI chatbot and the increase in unrepresented UK patent filings from November 2023 to July 2025.
The concern is what happens next. The success rate for unrepresented UK patent applications is routinely below 6%. Most of the self-filed applications made in 2025 were submitted without even requesting a search — the basic check on whether an invention is new. In other words, thousands of British inventors have paid to start the process and then let their idea lapse.
That pattern is not new, but it is accelerating. The IPO’s own research into the changing profile of users of the UK patent system found that applications from individuals fell from 38% of all filings in 2010 to 12% by 2018, and that individuals’ share of published applications halved, from over 20% to just over 10%. The report concluded that these applicants “tended not to pursue their applications to the publication or grant stages, whether through lack of interest or through lack of merit”.
A different story across the Channel
France recorded 16,807 patent filings in 2025, an increase of 8.7% and above pre-pandemic levels, according to INPI, the French patent office. French individuals accounted for 19% of those filings, with French companies making up 70%; filings from French SMEs rose 5%.
The gap is wider still at European level. In 2024, French applicants filed 10,980 European patent applications against 6,076 from the UK — 160.5 applications per million inhabitants in France, compared with 87.9 in the UK, according to the European Patent Office. Across Europe, SMEs and individual inventors together account for 22% of all European patent applications originating from EPO member states.
Alastair Swanwick, chairman of Innovate Design, said: “This is a shame for the UK, because people don’t realise they can get low-cost help to bring both their patent application and their idea up to a professional standard. A human patent drafting service raises the quality of the application, and that is how you make sure Britain captures as many good ideas as it can.”
The cost gap is the reason many inventors go it alone. The IPO warns that professional help “can cost several thousand pounds” on top of official fees, and UK patent attorneys commonly quote from around £4,000 plus VAT to draft an application. Innovate Design offers a patent drafting service for individual inventors at £1,100 plus VAT.
The IPO’s research attributes the loss of individual applicants in part to applications lacking merit. Innovate Design’s view is different: most inventors abandon their applications because they do not know affordable help exists — not only for drafting, but for prototyping and taking a product to market.
Swanwick added: “Where individuals don’t proceed with their ideas, it is usually because the next step looks unaffordable rather than because the idea is poor. By offering affordable options such as professional patent drafting, we help inventors validate their concept and move forward with it, instead of quietly giving up.”
The IPO publishes its next monthly filing figures on 27 August, which will show whether the rush of self-filed applications has continued into 2026.
Innovate Design has supported UK inventors for 25 years, helping individuals develop, protect and commercialise their ideas.
