MINNEAPOLIS, Feb. 01, 2017 (GLOBE NEWSWIRE) -- Clearfield, Inc. (NASDAQ:CLFD), the specialist in fiber management, optical pathway and connectivity platforms for communication service providers, reported today that it intends to vigorously defend against the patent infringement suit recently brought by CommScope in the United States District Court for the District of Minnesota. Clearfield invested significant resources in bringing to market the Clearfield’s FieldSmart® PON Cabinets, WaveSmart® Ruggedized Splitters, FieldShield® Deployment Reel System, SmartRoute® Panel, FieldShield® Multiport SmarTerminal and FieldShield® Hardened Connectors named in the suit and does not believe that these innovative products violate any valid intellectual property of CommScope.

Clearfield remains committed to pursuing its market development initiatives and to winning business with an expansive product offering to a broad customer base that recognizes Clearfield’s strong value proposition.”
