Jackson Walker Prevails with Federal Circuit Victory, Reverses PTAB in IPR Appeal


The Federal Circuit held, in a precedent decision, that the Board’s decision, holding Magnum’s patent  (U.S. Patent No. 8,079,413) invalid as obvious, was in error because the petitioner failed to articulate a valid reason why the patent was obvious.

The Federal Circuit agreed with Magnum that the Board improperly shifted the burden of proof to the patentee and that the petitioner failed to articulate a motivation to combine the cited prior art.  Significantly, the Federal Circuit emphasized that the Board cannot “raise, address, and decide unpatentability theories never presented by the petitioner and not supported by record evidence,” which helps to establish an important boundary on the authority of the Board during Inter Partes review.

Magnum was represented on appeal by John Jackson, Chris Rourk and Nate St. Clair.
