He did apply for patent.

Not for relativity. However, Einstein DID have a practical engineering side
to him, working to design a -safe- refrigerator with Leo Szilard. Their work
resulted in 45 patents.

Refrigerators were once dangerous appliances, from their use of ammonia as a

of a family that died while they were sleeping when their refrigerator
suffered a leak, and that was his initial motivation for teaming up with
Szilard.
