Beacon Power LLC Defeats Twin America Invents Act Validity Challenges to Patent

HOUSTON, April 29, 2015 /PRNewswire/ — Osha Liang LLP’s client Beacon Power LLC has defeated twin America Invents Act validity challenges to its U.S. Patent 8,008,804 covering the use of Flywheel Energy Storage Systems (FESS) for regulating the frequency of the electric power grid.

In late 2014, Temporal Power Ltd., a competitor in the emerging market for FESS applications, filed two petitions for Inter Partes Review (IPR), a type of validity challenge established in 2012 by the America Invents Act, in the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office.

Utilizing the optional procedure of filing a Preliminary Response, the Osha Liang team convinced the Board that in neither petition had Temporal Power established a threshold “reasonable likelihood” that it would prevail in challenging any of claims 1-26 of Beacon Power’s ‘804 Patent. As a result, on April 27, 2015 the Board denied institution of IPR trial proceedings for both of Temporal Power’s petitions, in Cases IPR2015-00146 and IPR2015-00147.

The Osha Liang legal team representing Beacon Power LLC was led by Peter C. Schechter and included partners Thomas K. Scherer and Tammy J. Terry, and firm founder Jonathan P. Osha.
