Quinn Emanuel successfully concluded an ITC investigation and parallel district court cases for, a leading developer and manufacturer of electronic marine navigation equipment. A team of Quinn Emanuel lawyers in the Tokyo, Los Angeles and Washington, D.C. offices asserted four of its client’s patents against three major marine electronics manufacturers. The asserted patents were directed to innovative ways of displaying and updating radar images, and to systems of networked multifunction displays and sensors that greatly improved the previous technology.
Working with multiple technical experts, the firm established a strong record of the respondents’ infringing activities. The firm further demonstrated its clients’ domestic industry with regard to the asserted patents. The firm developed all of this evidence through a global effort, with extensive discovery activity occurring in Japan, the United Kingdom, and in many cities throughout the United States. The respondents mounted a forceful defense, with particular emphasis on several purported prior art publications and systems which they claimed to be case-dispositive. Through intense depositions and motion practice, the firm barred one purported prior art system completely and exposed weaknesses in the remaining art. As a result of these efforts, the client achieved settlements with all three defendants on highly favorable terms.
