You do not need a firm on retainer to answer that question. Paste your patent number and ClaimHit searches the live market for products that practise it — showing you the source for everything it finds, so you can judge it yourself.
Paste a patent number from any major office. Claims are fetched automatically — no forms, no scoping call, no retainer.
Every match points at real evidence — a product page, a datasheet, a spec. If it cannot be evidenced, it is not shown to you as a finding.
An element-by-element chart maps your claim against a specific product. Whatever you do next, you arrive with the work already started.
The engine reports NONE where the record runs out and does not round a maybe up. An honest negative saves you far more than a flattering guess.
Candidates come from several models, live web and neural search, forward citations, and the authoritative registries for the field — but breadth only widens the net. Each one is still checked against real, citable evidence, and anything that cannot be evidenced is dropped rather than shown with a caveat. See every source →
It costs a lot less to check than to wonder.
