The AI patent race: why startups must plan past the filing

The useful part

The AI patent race – Why startups need to think beyond filing September 21, 2026 Gen AI Latest News Start-Up Corner For AI start-ups, filing a patent may seem like crossing the finishing line. An invention has been found, the application is ready and the company can then get on with building the product. The pace of AI development is making that distinction increasingly important.

How it works

• It's about deciding what really deserves protection, how that protection fits into the broader company picture and whether the end result will be a useful IP position as the technology continues to evolve.
• However, the quantity of applications filed is an extremely poor substitute for the quality of the underlying IP strategy.
• An AI company might hold patents on individual model architectures, data processing techniques or application workflows whilst its competitors can quite easily design around those claims.
• AI systems frequently combine multiple technical components, including models, infrastructure, data-processing methods, optimisation techniques and application-specific workflows.
• A search should not necessarily be treated as a report produced immediately before filing and then placed aside.

What to take from it

Advertisement The challenge for start-ups is therefore no longer just determining whether an invention is patentable. Freedom to operate matters as much as ownership There is another risk in focusing too heavily on filing: owning a patent does not necessarily mean having freedom to commercialise the underlying technology. The objective is not to prove that every conceivable legal risk has disappeared.

Example or evidence

• More than 56,000 were published across 2024 and 2025 combined, exceeding the total for the preceding decade.
• Early prior-art research can give inventors and patent professionals an opportunity to consider claim scope and fallback positions before an application is locked into a particular approach.
• It's especially important as start-ups rely more and more on AI itself during both research and development.
• For AI start-ups, the biggest challenge will be building an IP strategy that links invention, evidence, freedom to operate and commercial strategy.

Details worth keeping

In reality, filing is much more like the starting line. An IP portfolio can become quite large without ever being strategically valuable. Advertisement A patent is not automatically a competitive moat Start-ups are frequently encouraged to build a patent portfolio because patents can signal technological capabilities to investors, potential acquirers and competitors.
