Representative Matters

  • Lead trial counsel in numerous lawsuits representing one of the largest international manufacturers of consumer electronics being accused of infringing:
    • Two patents directed to the use of LED based television backlighting schemes. One patent was dismissed without any payment shortly after a petition for inter partes review was filed. The remainder of the case settled on favorable terms to client.
    • Patents directed at video format conversion software. The case started in the Eastern District of Texas, wound its way through the Federal Circuit, the United States Supreme Court and ultimately landed in the Northern District of California where a settlement tantamount to total victory was achieved hours after oral argument on a motion for summary judgement of invalidity. Subsequently, the court granted defendants’ summary judgement motion of invalidity, thereby successfully ending six years of litigation for all defendants.
    • Two patents directed to three dimensional computer graphics. A dismissal of all claims was obtained prior to any discovery being exchanged.
    • Four patents directed to semiconductor wire grid polarizer optical technology. Negotiated a dismissal of the suit and facilitated settlement discussions in a collegial atmosphere that resulted in a favorable outcome for client without the expense of maintaining a lawsuit.
    • Two patents owned by a well-known patent assertion company. The case was originally filed in the Western District of Arkansas and then transferred to the Northern District of California. Mr. Popovski used N.D. Cal.’s Local Patent Rules to preclude plaintiff from obtaining any discovery prior to establishing a prima facie case of infringement, which plaintiff was not able to do. In two seminal opinions on the disclosure requirements of the local rules, the court twice struck plaintiff’s infringement contentions, the second time without leave to amend thereby effectively disposing of the case before his clients and others had to provide any discovery.
    • A patent directed to highly complex encryption methods using elliptical curve cryptography. Case was dismissed without any payment to plaintiffs.
    • Four patents directed to the manufacture, structure and operation of the blu-ray laser diodes used in the PlayStation line of products. In this ultra-high stakes litigation directed at core product lines, Mr. Popovski was able to get three of the patents dismissed for zero compensation and obtained a rare summary judgement of invalidity of the fourth patent on the eve of the trial.
    • Several patents directed to computer generated spherical panning features associated with computer and console games. Case settled on favorable terms for client.
  • Lead trial counsel for a fortune 500 company defending two lawsuits asserting three patents directed to enterprise simulation software and enterprise monitoring software. The first lawsuit was dismissed without any payment. The second lawsuit was on summary judgement where the court held that the asserted claims were directed to subject matter that is ineligible for patent protection and thus invalid.
  • Lead trial counsel for an individual inventor that asserted a patent directed to DOCSIS compliant cable communication systems having load balancing capabilities on behalf of a technology company. Obtained favorable settlement on eve of trial after prevailing on all claim construction issues and key pre-trial motions.
  • Asserted a patent directed to mass spectrometers having improved sensitivity against a major competitor’s high end triple-quadrupole mass spectrometer product line. Mr. Popovski’s efforts resulted in the fourth largest jury award of 2002 and an injunction prohibiting sales of the infringing products worth hundreds of millions of dollars per year. The Federal Circuit affirmed the damages award and entry of the injunction in a per curium decision shortly after oral argument.
