Nate St. Clair’s Defense of Jackson Walker Client’s Patent Featured in Law360
Jackson Walker partner Nate St. Clair argued in front of a Federal Circuit panel in defense of a fracking plug patent owned by Jackson Walker’s client, Magnum Oil Tools International (“Magnum”). The defense was featured in a Law360 article titled, “USPTO Grilled over PTAB Ruling In Settled Patent Row,” (subscription required).
After Magnum accused McClinton Energy Group (“McClinton”) of infringing on their patent in district court, McClinton requested the Patent Trial and Appeal Board (PTAB) conduct an IPR review of the patent. The IPR proceedings at the patent office continued through Final Decision, despite the fact that Magnum reached a favorable settlement in the original District Court litigation.
Magnum then appealed the PTAB ruling to the Federal Circuit, and the U.S. Patent and Trademark Office (USPTO) stepped in to defend its appeals board decision that the patent was obvious in light of prior art, despite the fact that McClinton was no longer involved.
Mr. St. Clair, on rebuttal to testimony by the USPTO in-house attorney that the agency would enjoy “maximum discretion” if the case would be remanded back to the PTAB, said the IPR has “put us in a precarious position,” that was “not what Congress intended.”
Mr. St. Clair argued the PTAB improperly found the Magnum patent obvious, that the board made a “mental shortcut” in assembling the prior art to resemble Magnum’s fracking plug invention, and that the line of argument was never mentioned in McClinton’s initial petition.
Jackson Walker partners John Jackson and Christopher Rourk joined Mr. St. Clair in defending Magnum in the appeal to the Federal Circuit.
