On July 13, 2015, ALJ Theodore R. Essex issued a notice of the Initial Determination ("ID") in Certain Marine Sonar Imaging Systems, Products Containing the Same, and Components Thereof (Inv. No. 337-TA-926).

By way of background, this investigation is based on a July 18, 2014 complaint filed by Johnson Outdoors Inc. and Johnson Outdoors Marine Electronics, Inc. alleging violation of Section 337 in the importation into the U.S. and sale of certain marine sonar imaging systems, products containing the same, and components thereof that infringe one or more claims of U.S. Patent Nos. 7,652,952 (the '952 patent); 7,710,825 (the '825 patent); and 7,755,974 (the '974 patent).  See our July 23, 2014 and August 21, 2014 posts for more details on the complaint and Notice of Investigation, respectively. 

According to the notice, ALJ Essex determined that no violation has occurred with respect to the '952 patent, the '825 patent, and claim 25 of the '974 patent.  However, ALJ Essex also determined that a violation of Section 337 "has occurred in the importation into the United States, the sale for importation, or the sale within the United States after importation of certain marine sonar imaging systems, products containing the same, and components thereof by reason of infringement of claims 14, 18, 21, 22, 23 and 33 of [the '974 patent]."

The July 13 notice issued by ALJ Essex only provided limited information.  We will provide an update after the public version of the ID issues.
