Dale is correct. RCA owned the patent for the superhet design and licensed the design to any company with the right compensation. This notice had to be attached to every radio under the license agreement. Sarnoff was not a hospitable person.

This appears to be a post-war model as pre-war radios with phono jacks were rare.
