Another Win for MIAX – Five NASDAQ Patents Invalidated by PTAB MENA Press Release October 11, 20190 PRINCETON, N.J., Oct. 11, 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 fifth 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. The PTAB ruled in its final written decision that all 30 claims of Nasdaq’s U.S. Patent No. 8,386,371 are unpatentable under 35 U.S.C. Section 101. Five Nasdaq patents have now been invalidated by the PTAB over the past two weeks: U.S. Patent Nos. 6,618,707 (October 1), 7,246,093 (October 1), 7,921,051 (October 3), 7,747,506 (October 9) and 8,386,371 (October 10). A total of six patents were asserted by Nasdaq in its complaint. The PTAB has yet to rule on the one remaining patent. “With five patents now invalidated in our favor, the anticompetitive nature of Nasdaq’s complaint is very apparent,” said Thomas P. Gallagher, Chairman and CEO of MIH. Said Barbara J. Comly, Executive Vice President and General Counsel of MIH, “We believe that the PTAB issued very strong opinions with respect to the five Nasdaq patents invalidated to date, and we are very pleased with the outcome.” Continued Gallagher, “We have always welcomed the opportunity to compete with Nasdaq on the merits of our technology and functionality in the capital markets, not in a courtroom over the merits of unpatentable claims, which ultimately negatively affects our member firms and the entire trading community.” For further information regarding MIAX, please visit www.MIAXOptions.com or contact MIAX Trading Operations at TradingOperations@MIAXOptions.com.
