Bullitt Group was a UK rugged-phone maker (corporate HQ One Valpy, Valpy Street, Reading, Berkshire) that built and sold devices under licensed brands — CAT (Caterpillar), JCB, formerly Land Rover and Kodak, and the Motorola Defy satellite phone. No IEEE OUI was found for "Bullitt Group," "Bullitt Mobile," or "Bullitt" on maclookup.app, hwaddress.com, or udger.com — a negative finding. The reason is structural: Bullitt was a fabless brand-licensee whose devices were built by Chinese ODMs on third-party chipsets (commonly MediaTek), so the MAC prefixes on its devices belong to the ODM or chipset maker, not to Bullitt. The company entered financial difficulty and ceased operations: Bullitt laid off all employees and closed on 2024-01-26 after a planned restructuring failed (it had over 200 employees). This is a "maker vs. licensee" case that resolves to a negative finding. For triage, do not expect a "Bullitt" or "CAT" OUI — a CAT-branded rugged phone surfaces under its chipset or ODM's OUI (often MediaTek), and the brand on the device is a licensed name rather than the MAC registrant.

- Special note
- "OUI = maker, brand = licensee" case resolving to a negative finding. Bullitt was a fabless brand-licensee; devices were built by Chinese ODMs on third-party chipsets (e.g., MediaTek), so MAC prefixes belong to the ODM/chipset maker, not Bullitt. The IEEE registry publishes no assignment dates, and Bullitt has no OUI. [Likely]

- Analyst note
- Don't expect a "Bullitt" or "CAT" OUI — a CAT-branded rugged phone surfaces under its chipset/ODM's OUI (often MediaTek); the brand on the device is a licensed name, not the MAC registrant.
