Order a search

Prior-art search on an issued patent, run the way an examiner runs it.

Pick a tier. The two sweeps run automatically and come back within 24 hours with the full search record. The three signed searches are read, charted and signed by a former USPTO examiner, and are invoiced after a conflict check.

Launch pricingSigned searches at launch prices through December 31, 2026. Standard prices shown struck through.

Your first preliminary search is free. One per person; up to five per firm in any 60 days. $99 a sweep after that. Every report is read by a former USPTO examiner before it goes out and carries the full search record. The fee is credited in full against a Case Brief or a signed search on the same patent within 60 days.
