Maier & Maier Wins Contested Institution Decision for Petitioner in Inter Partes Review

The Maier & Maier litigation team scored another victory at the Patent Trial and Appeal Board (PTAB), securing an institution order on behalf of the Petitioner, Eve Energy Co., Ltd. (“Eve”).  Despite Patent Owner Varta Microbattery GmBH’s Patent Owner Preliminary Response, the PTAB has determined that Maier & Maier, on behalf of Eve, demonstrated a reasonable likelihood that it will prevail with respect to at least one of the challenged claims.

On behalf of Eve, Maier & Maier challenged claims of U.S. Patent No. 9,496,581 on obviousness grounds.  Maier & Maier’s strategic use of testimonial evidence appears to have greatly benefited its position, while the Patent Owner Preliminary Response was limited to attorney argument without testimonial evidence.  In reaching its decision, the PTAB also agreed with Eve’s asserted level of ordinary skill in the art and Eve’s assertions regarding claim construction.

On August 9, 2021, the PTAB ordered that the inter partes review be instituted for all challenged claims.

Maier & Maier Mounts Yet Another Successful Defense at the PTAB

In their latest triumph at the PTAB, Maier & Maier PLLC has won a major victory for GREE, Inc. by securing a non-institution decision, overcoming 3 challenges to their social gaming patent asserted by Supercell Oy in PGR2018-0037.

The challenged patent (9,662,573) covers a method for controlling a server device, a server device, a computer-readable recording medium and a game system. Supercell challenged the patent on three grounds: §101, §112(a), and §112(b).

The PTAB denied institution of the challenge as to all of the claims.  The PTAB explained their decision on the §101 challenge, stating “we are unpersuaded by Petitioner’s argument that providing these sequential incentives, as claimed, was conventional and known in the prior art.”  The analysis goes on to emphasize that Supercell failed to provide evidence, such as expert testimony or contemporaneous prior art, and also failed to provide relevant case law or persuasive argument to support its contention. Meanwhile for the §112 challenges, Maier & Maier successfully demonstrated that the patent was “cast in clear—as opposed to ambiguous, vague, indefinite—terms” and that Supercell “offered no credible evidence to support its assertion”.

Since Maier & Maier showed that none of the asserted grounds for unpatentability demonstrated a reasonable likelihood of success, as discussed above, the PTAB issued a decision denying institution, dealing Supercell a serious blow in their ongoing patent litigation.
