How to search for existing patents
Find out why patent searches matter, how to search for patents, and what to check to confirm your idea鈥檚 originality.
Before applying for a patent, you should check if your invention is truly original by conducting a patent search. This helps confirm that no one else has already patented a similar idea.
Why patent searches matter
A patent search will help you:
- avoid infringement - ensure you're not copying someone else's patent
- save money - avoid the cost of applying for something already patented
- strengthen your application - prove your invention's novelty
Before searching, take time to understand what patents are and how they work to ensure they are right for your invention.
How to conduct a patent search in the UK
Several steps are involved:
Search online databases and use the UK patent search tool
When searching for existing patents, start with online databases to verify that your invention is new and hasn't already been patented. Useful resources include:
- - for UK patents
- - for European and international patents
- - for global searches and applications filed under the Patent Cooperation Treaty (PCT)
You can also check the IPO's , which lists new filings and changes to applications already in progress.
Look beyond patents
Looking beyond patents is critical to ensure your invention is both novel and commercially viable. While patent databases help identify existing patents, other resources provide insights into whether your idea or technology is already in use, even if it hasn't been patented. Check trade publications, industry forums, product catalogues, research papers and technical reports.

What to look for when carrying out a patent search

A thorough patent search not only ensures your invention is new, but also helps you avoid infringement and the potential consequences of breaching patent enforcement laws. It also allows you to identify competitors, understand the market for your invention, and ensure that you have the freedom to operate without legal risks.
