Space Technology Patent Classification
Space hardware classifies in a single dedicated subclass: B64G for cosmonautics. Satellites, launch vehicles, docking systems, thermal control and orbital debris removal all sit here.
The volume is small compared to terrestrial technologies, but the commercial space wave is visible in the filing trend. Satellite communication payloads additionally classify in H04B on the transmission side.
