Free EPO OPS search
Search Patents Before Market and Account Research
Search patent publications and applications with EPO Open Patent Services data. Use it to research ideas, competitors, technology areas, or prospect companies.
How patent search works
Start broad, then narrow based on the results
Use patent search as a first scan: find the right terms, applicants, and publication numbers before deeper expert review.
- 01
Search by technology or company
Try a product, material, method, company, or inventor name. Patent language can differ from everyday marketing language. - 02
Filter by geography and time
Narrow results to European or WO publications and use date filters when looking for recent signals. - 03
Open promising results at the source
Move to Espacenet when you need the patent family, claims, drawings, legal status, or official document view.
What the search can tell you
Use patent data for early research
This tool helps find patent publications through the EPO OPS API. Questions about patent validity, infringement risk, novelty, or selling a product in a specific country require a separate expert review.
EPO OPS as the source
The search uses the European Patent Office Open Patent Services API, whose data comes from the same sources as Espacenet and the European Patent Register.
Interpretation needs expertise
A single search result leaves open whether a patent is active, relevant, or blocking. For critical decisions, involve a patent professional.
