On March 24, 2017, the U.S. District Court for the District of Delaware entered final judgment in favor of Banner & Witcoff client, Unum Group.
In MPHJ Technology Investments, LLC v. Unum Group, Case No. 1:14-cv-00006-SLR, the district court entered final judgment in favor of Unum Group after Banner & Witcoff client Lexmark International, Inc. successfully demonstrated via inter partes review that all asserted claims of MPHJ’s U.S. Patent Nos. 8,488,173 and 7,477,410 were invalid. Lexmark requested inter partes review of the asserted patent claims because Lexmark is the developer, designer and manufacturer of certain hardware and software that Unum was accused of infringement. During the inter partes review proceedings, Lexmark successfully demonstrated the invalidity of the asserted claims based upon prior invention by others.
Unum Group and Lexmark International, Inc. are represented by Banner & Witcoff attorneys Timothy C. Meece, V. Bryan Medlock, Jr., Jason S. Shull, Michael J. Harris, and Audra Eidem-Heinze.
