get_chain_of_title
shallowcom.gleanmark/trademark-search · Verify this server
Trace who has owned a trademark over time — the ownership stages USPTO recorded (original applicant/registrant through each successive new owner), plus any recorded assignment documents we hold. Use this whenever the user asks who owns a mark now versus who filed it, whether a mark was sold, transferred or assigned, how it came to its current owner, or for chain-of-title / due-diligence questions. lookup_trademark returns only the CURRENT owner and cannot answer any of these. Owners listed within a single stage are joint owners, not successive ones. Not a title opinion.
