Which company owns MAC address prefix 04:67:85?

MAC address prefix 04:67:85 is registered to scemtec Hard- und Software fuer Mess- und Steuerungstechnik GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:67:85 has a network interface built by scemtec Hard- und Software fuer Mess- und Steuerungstechnik GmbH.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:67:85:00:00:00 that is 04:67:85 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.
