Jaime Cardenas-Navia Featured in Law360 on RJLF's PTAB Reexam Win for IOENGINE

Partner Jaime F. Cardenas-Navia was featured in Law360's article, "PTAB Revives Ioengine Data Patent In Roku Reexam Case," discussing a Patent Trial and Appeal Board decision reviving nine claims in an IOENGINE LLC data processing patent. The win came in the firm's defense of Ioengine's U.S. Patent No. 10,447,819 in a reexamination brought by Roku.

In a decision this week, the PTAB panel revived the nine claims that an examiner had rejected on obviousness grounds in the reexamination Roku initiated. The board found that the examiner misread key claim-construction terms and called the examiner's approach to certain issues "problematic."

Much of the dispute turned on what it means for something to be "a portable device." The examiner's interpretation accounted only for the device's physical portability and not its functional portability, which the panel said "is not only an important feature, it is the very focus" of the patent. The panel also faulted the examiner for concluding that a prior art reference covered the portable device, noting that the referenced device "is physically portable" but "is not functionally portable."

The ruling is the second favorable reexamination result for IOENGINE in recent months. In May, the PTAB disagreed with an examiner's rejections of claims in a related Ioengine patent, U.S. Patent No. 10,972,584, which was also at issue in the same infringement litigation.

Cardenas-Navia told Law360 that IOENGINE "is pleased that the patent office has confirmed the validity of the '819 patent after a thorough reexamination." He added that the decision, "combined with the patent office's recent determination that all 99 claims of the '584 patent are valid, underscore the breadth and novelty of [Ioengine's] patented technology."

IOENGINE is represented by Mark I. Koffsky of Koffsky Schwalb LLC and Jaime F. Cardenas-Navia of Reichman Jorgensen Lehman & Feldberg LLP.
