Archive-name: info/spacedrives/World Patents List - June 1996 Abstract: This report results from an extensive survey of various Patents Databases, searching for all patents relating to the non-rocket space propulsion concept (i.e. Spacedrives). Definition: Spacedrive is the generic term used to denote a mechanism, or principle by which a spaceship can be propelled - a device, not a rocket - that would not have to carry reaction mass to throw away.

Compilers Notes: This listing, and other spacedrives info, will not be automatically posted but will be made available via a website in the near future.
Up-dating will be on a bi-annual basis, in Jan and July. Reports of errors or ommissions should be sent to: (Email), (Snail-Mail) Roger Cook, POB 228, Kingston Springs, TN USA, (Dial-Up BBS) Spacedrives OnLine Archives, up to 33.6 Kbps, 615.952.5638, User-Id: rdcook.

Patent Copies: Copies of U.S. patents, for delivery within the U.S., can be ordered from the Commissioner of Patents, Washington, DC, 2O231. Order by Patent Number, and include $3.OO for each patent copy ordered. Applies to U.S. orders only! ALL others should query their national Patent Office for pricing and ordering instructions
