Electrical and Software

Patterson Belknap attorneys have a strong track record representing clients in cases involving electrical, telecommunications, and computer technologies as well as a vast array of software products and features. Team attorneys have represented:

  • A Fortune 50 technology company accused of infringing multiple patents relating to audio/video conferencing and encryption. In the Eastern District of New York, we secured final judgment of non-infringement in favor of our client. The Federal Circuit affirmed.
  • A home shopping network in defense of allegations of infringement of a patent directed to a computerized system for performing a reverse auction. A Tennessee district court dismissed the case without prejudice after our Petition for Covered Business Method (“CBM”) Review was granted by the Patent Trial and Appeal Board (“PTAB”). The PTAB subsequently found all 39 claims of patent invalid as directed to ineligible subject matter and denied Patent Owner’s motion to amend the claims.
  • A leading electronics company in the Southern District of California and the PTAB, defending claims of infringement of 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.
  • A leading electronics company in the Eastern District of Texas, defending claims of patent infringement directed at video format conversion software. The case 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.
  • A leading electronics and software manufacturer in defense of claims of patent infringement directed to the use of voice recognition technology by cell phones. The matter is presently pending in the District of Colorado.
  • A leading electronics company in defense of claims of infringement of two patents directed to three dimensional computer graphics. A dismissal of all claims was obtained in the Northern District of California prior to any discovery being exchanged.
  • A leading technology company in defense of two lawsuits asserting patents directed to enterprise simulation and monitoring software in the District of Delaware. The first lawsuit was dismissed without any payment. The second lawsuit was won after a summary judgement decision finding that the asserted claims were invalid as being directed to subject matter that is ineligible for patent protection.
  • A communications company in the Eastern District of Texas in the successful assertion of a patent directed to DOCSIS compliant cable communication systems having load balancing capabilities. Obtained a favorable settlement on eve of trial after prevailing on all claim construction issues and key pre-trial motions.
  • A leading electronics company in the District of Utah, defending allegations of infringement of 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 both parties.
  • A leading multinational engineering and electronics company in the Eastern District of Virginia and the ITC, defending against allegations of infringement of patents concerning video analytic software for security camera systems, such as virtual tripwire technology, in both district court and ITC proceedings. The case settled on favorable terms to client shortly after ITC hearing.
  • A data visualization software developer in a declaratory judgment action in the Southern District of New York brought in response to claims of infringement of a patent covering a system for automating the collection, management and analysis of data. Case settled favorably for client with minimal expense.
  • The subsidiary of a Fortune 50 software company, which was accused of infringing two patents on speech recognition technology in the District of Delaware. The plaintiff voluntarily dismissed the first patent after we made a strong showing of non-infringement. Defeated the second patent on summary judgment by proving that each claim of the patent was anticipated by or obvious over prior art that we uncovered.
  • A multinational mass media group in a case in the District of Delaware involving a patent on links used in internet searches. Case settled on terms highly favorable to our client.
  • A leading provider of technologies used for determining the location of wireless devices, in a declaratory judgment action in the District of Delaware against a competitor. Developed strong non-infringement positions showing that our client’s new location platform did not infringe a patent owned by its competitor. Prior to trial, our client decided to make additional improvements to its platform and withdrew the lawsuit.
  • A leading electronics and software company, defending allegations of infringement relating to two patents owned by a subsidiary of a well-known patent assertion company. Case was originally filed in the Western District of Arkansas and then transferred to the Northern District of California. Used the Northern District of California’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 effectively disposing of the case before defendants had to provide any discovery.
  • A national provider of anatomic pathology services, which was accused in the Eastern District of Texas of infringing two patents on computer software for formulating a therapeutic regimen for patients for the treatment of disease. Case settled on favorable terms for our client.
  • A leading electronics company in defending claims of patent infringement in the Eastern District of Texas directed to highly complex encryption methods using elliptical curve cryptography. Case was dismissed without any payment to plaintiffs.
  • A leading electronics corporation in defending claims in the Eastern District of Texas of infringement of four patents directed to the manufacture, structure and operation of the blu-ray laser diodes used in a top video gaming line of products. In this ultra-high stakes litigation, three of the patents were dismissed for zero payment and the court granted a rare motion for summary judgement that the fourth patent was invalid just days before trial was set to begin.
  • An international manufacturing company in defending in the Eastern District of Texas an accusation of patent infringement on technology for graphically displaying the scheduling of resources. Our early investigation uncovered prior art from inside and outside the company which we used to obtain an early settlement of a potentially troubling case for a minimal sum.
  • An international manufacturing company, which was accused in the Eastern District of Texas of infringing a patent on circuit breakers. Case settled on favorable terms for our client.
  • A Fortune 50 software manufacturer in two cases in the Eastern District of New York where it was accused of infringing patents relating to video computers and cellular phones. In both of these cases, the district court granted our motions for summary judgment in our client’s favor. One of these cases was appealed to the Federal Circuit and the grant of summary judgment in favor of our client was affirmed.
  • A leading electronics manufacturer in the Eastern District of Texas, defending claims of patent infringement of several patents directed to computer generated spherical panning features associated with computer and console games. Case settled on favorable terms for client.
  • A technology company in asserting a patent in the District of Delaware directed to mass spectrometers having improved sensitivity against a major competitor’s high end triple-quadrupole mass spectrometer product line. A jury awarded the client the fourth largest jury award of its year, and the Court entered an injunction prohibiting sales of the infringing products. The Federal Circuit affirmed the damages award and entry of the injunction in a per curium decision shortly after oral argument.
