How we work

A search you can check.

The search record is in the report

Every query, class and database, with dates and hit counts. “Nothing found” becomes something you can check.

Every reference read in the original

Nothing reaches a chart on an abstract or a snippet. Quotes carry column-and-line cites, checked against the text.

An honest no

If the art isn't there, the report says so and says how hard it looked. A negative arrives as evidence, not an assurance.

Patents in suit

142 patents asserted against 3 or more defendants

Every docket and the examiner-cited art. One search serves every defendant who shares the patent. Campaigns include ABC IP, LLC, Near Field Electronics LLC, Lone Star Document Management, LLC.
