Patent claim infringement check

How it works

1

Describe your product

Write a technical description of what your product or feature does — the more specific, the more accurate the analysis.

2

Semantic patent search

We use AI embeddings to find active patents in our enriched corpus that are most similar to your description.

3

Element-by-element analysis

For each relevant patent, an AI attorney analyzes whether your product practices every limitation of the independent claims.

4

Design-around suggestions

For any flagged patents, we suggest specific ways to modify your product to avoid the claim — no element-by-element infringement.

Important caveat

This tool only covers patents in our enriched corpus — not all active US patents. A "likely clear" result does not mean no patent risk exists. For business decisions, always get a formal freedom-to-operate opinion from a registered patent attorney.
