The Company owns all rights, title and interest in one currently pending U.S. patent application, one currently pending Patent Cooperation Treaty (“PCT”) patent application, and two U.S. federal trademark registrations.
The U.S. and PCT patent applications both cover the same technology, namely vertical axis wind turbines with segmented Savonius rotors. The Savonius rotor is assembled by interlocking several relatively small and easily manageable individual blade segments. This unique segmented design has several advantages over traditional vertical axis wind turbine designs, including ease of manufacturing, ease of assembly, and suitability for residential use.
The U.S. patent application (serial no. 11/705,844) was filed on February 13, 2007 and first published on August 14, 2008 as U.S. patent application publication no. 2008/0191487. The application remains pending by the U.S. Patent Office. Assuming a patent is granted and that no patent term adjustments are made, the patent will expire on February 13, 2027.
The PCT patent application (serial no. PCT/US2008/001983) was filed on February 13, 2008 and claims priority to the Company’s U.S. patent application serial no. 11/704,844. The International Searching Authority issued a Written Opinion on July 1, 2008. Helix Wind responded to the Written Opinion on September 30, 2008. The application has not yet entered the national phase in any country, although Helix Wind may prosecute the application in all 138 PCT contracting states. The term of any patent that issues in a foreign country depends on the law of that country, but in general is 20 years from the filing date.
The Company owns U.S. federal trademark registration no. 3,524,780 for “HELIX WIND,” registered on October 28, 2008. The registration is due for renewal on October 28, 2018. Helix Wind also owns U.S. federal trademark registration no. 3,506,184 for “E2 ENERGY (R)EVOLUTION,” registered on September 23, 2008. The registration is due for renewal on September 23, 2018. Both of these U.S. federal trademark registrations are in International Class 007 for use in connection with “wind turbines and accessories for wind turbines.”
