Where this comes from

OneTwelve ownership graph, as of 2026-09-23. Recorded USPTO assignments (ownership transfers, mergers and name changes; security interests, releases and inventor assignments excluded). Patent counts sum the properties on the recorded documents. Group membership per the OneTwelve entity map; joined-the-group dates come from corporate registry records and reviewed disclosures. Moves of 40+ patents are shown; inventor-to-employer assignments are excluded. Recorded assignments show where patents moved; on their own they do not prove the business reason for a move. Story captions are generated from the recorded moves.
