Patent counts refer to distinct records held by this site, not an applicant’s complete portfolio. A joint name field is not a single company.

Verified corpus date coverage and last import time are not currently available. Publication dates on patent records are not import dates. Cached directory results may lag behind new imports.

Name indexes cover 159578 of 160352 local patent records. Entries label whether XML name boundaries were verified or the whole original field is displayed. Unindexed patents remain searchable.
