PTAB Invalidates Third NASDAQ Patent in Favor of MIAX; Finds all 49 Claims UnpatentableMENAPress Release October 4, 20190PRINCETON, New Jersey, Oct. 4, 2019 /PRNewswire/ — Miami International Holdings, Inc. (MIH), the parent holding company of the MIAX Options®, MIAX PEARL® and MIAX Emerald™ exchanges (MIAX), today announced that a third Nasdaq patent asserted against MIAX as part of its infringement complaint has been found invalid by the Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office. In its final written decision, the PTAB ruled that all 49 claims of Nasdaq’s U.S. Patent No. 7,921,051 are unpatentable under 35 U.S.C. Section 101.Nasdaq asserted infringement on six patents in its complaint against MIAX. This PTAB ruling marks the third consecutive Nasdaq patent to be invalidated, as the PTAB made the same ruling on two other patents earlier this week. The three remaining patents have yet to be decided by the PTAB.“We could not be more pleased with these PTAB rulings and how this case is progressing,” said Thomas P. Gallagher, Chairman and CEO of MIH. “With each PTAB ruling that invalidates another Nasdaq patent it becomes more and more apparent that this infringement complaint is groundless and should have never been filed in the first place.”For further information regarding MIAX, please visit www.MIAXOptions.com or contact MIAX Trading Operations at TradingOperations@MIAXOptions.com.Corporate Communications Contact:Dominique Prunetti-Miller(609) 897-1465 email@example.com About MIH Miami International Holdings, Inc.
