Talk:Airless tire
From Wikipedia, the free encyclopedia
I just checked the US patent database and it seems that the statement "Currently the firm New Tech Tire Inc. owns all patent rights to non-pneumatic tires" needs verification.
Goodyear (US5343916: Non-pneumatic spare tire) and others (Motor Wheel Corp., Michelin Recherche et Technique S.A. etc) enjoy US patents in the area of non-pneumatic tires. Does New Tech have exclusive licenses to all of these patents?
