TrafFix Devices, Inc. Files Patent Infringement Suit Against Lindsay Transportation Solutions, LLC

TrafFix Devices, Inc., a leader in producing innovative road safety products, has filed a patent infringement lawsuit in California against Lindsay Transportation Solutions, LLC.

In the lawsuit, TrafFix Devices alleges that making, selling, or using Lindsay Transportation’s ABSORB-M crash cushion in the United States infringes four patents relating to the innovative design of TrafFix Device’s popular Sentry Longitudinal Energy Dissipater (SLED®) line of crash attenuators. The SLED® crash attenuators are supported by TrafFix Devices significant investment in research and development. All four of the patents asserted in the lawsuit relate to technology for end treatment arrays for crash attenuation.

TrafFix Devices asked the court for an injunction barring sales of Lindsay Transportation’s infringing crash cushions, payment of money damages due to TrafFix Devices lost sales, and to recover its attorney fees for the lawsuit.

Brent Kulp, TrafFix Devices, Inc. President, commented that: “TrafFix Devices is committed to staying on the cutting edge of product innovation, and to protecting the valuable intellectual property that we incorporate into our highway safety products. We will not tolerate infringing copies of our innovative products.”

“TrafFix Devices had no choice but to take legal action to stop Lindsay Transportation’s ongoing and unlawful infringement of TrafFix Device’s patented technology,” said Christy Lea, counsel for TrafFix Devices and litigation partner at Knobbe Martens, a leading Intellectual Property law firm.

TrafFix Devices Prevails in Court

Fisher Phillips said client TrafFix Devices, Inc. won a race discrimination and wrongful termination case in Orange County Superior Court.

Fisher Phillips is a labor and workplace law firm based in Atlanta and with offices in about 30 cities, including Irvine.

San Clemente-based TrafFix makes products to control traffic and reduce the frequency and severity of automobile collisions.

Its ex-employee Barbara Ijeh Egbuta, a Nigerian immigrant — after making an internal complaint and a company investigation — sued for $12 million alleging discrimination based on race and national origin, unlawful retaliation, and wrongful termination.

Fisher Phillips argued that wrongful termination only applies if a complaint is filed in good faith, and that based on Egbuta’s complaint, the company’s investigation and employee interviews, she couldn’t reasonably believe her actions were protected.

The trial began in May and lasted 18 days.
