On July 29, 2015, the public version was issued of Judge Shaw’s Final Initial Determination On Violation And Recommended Determination On Remedy in Certain Marine Sonar Imaging Devices, Inv. No. 337-TA-921, determining that a violation of Section 337 had not occurred. As mentioned in prior coverage on July 14, 2015, Navico Holdings AS and Navico, Inc. (“Navico”) accused underwater scanning devices comprised of head units, sonar processing units, and transducers using “downscan” sonar technology, sold by Garmin International, Inc., Garmin USA, Inc., and Garmin (Asia) Corp. (“Garmin”) of infringing Navico’s patents. In his 320-page opinion, Judge Shaw found that Garmin’s products do not infringe the asserted patents because they do not satisfy the limitation of a “linear downscan transducer” under the proper construction of that claim phrase because the plurality of elements in Garmin's transducers do not operate as if they were a single element. The accused products also were found not to infringe the asserted ’499 patent because they do not merge together conical and linear data, as required by the claims. Judge Shaw found that Garmin was not liable for indirect infringement both because the accused devices do not directly infringe and because the evidence showed that Garmin purposely designed around what it believed was the scope of the Navico patents, and thus lacked intent to infringe, and certain of Garmin’s devices have substantial non-infringing uses. On July 30, 2015, Navico filed a Petition For Review, and Garmin filed a Contingent Petition For Review, of the Final ID.
