In interstellar law, the space salvage laws dealt with the salvage rights for spacecraft and their contents.
Citing space salvage laws, interstellar trader Cyrano Jones acquired a Klingon glommer in 2269 and escaped with it from Klingon space. Captain Kirk did not recognize his claim on the grounds that the glommer was taken from the surface of a planet, and not from a spacecraft. (TAS: "More Tribbles, More Troubles").
