Heraeus Medical GMBH v. Esschem Inc

by
Heraeus, a German company, develops and produces bone cement, using copolymers. Biomet also sells bone cement and uses the same copolymers, which it buys from Esschem, a Pennsylvania company. Heraeus holds trade secrets related to the bone cement, including specifications for the copolymers. The trade secrets changed hands during joint ventures before allegedly falling into Esschem’s possession. Heraeus analyzed samples of Biomet’s bone cement in 2005 and discovered that it was virtually identical to Heraeus’ bone cement and that Esschem was manufacturing Biomet's copolymers. Heraeus sued Biomet in Germany in 2008, and brought discovery suits in the U.S. against Esschem and Biomet. By March 2011, Esschem produced e-mail chains between employees of Biomet and Esschem concerning the copolymers. During proceedings against Biomet, that information was corroborated. Heraeus contends it was not until then (December 2011), that it had sufficient information to believe that Esschem had actively participated in the misappropriation of its trade secrets. Less than three years later, Heraeus sued Esschem under the Pennsylvania Uniform Trade Secrets Act (PUTSA) which gives a plaintiff three years from when “the misappropriation was discovered or by the exercise of reasonable diligence should have been discovered” to bring suit. The district court ruled that the limitations period had run because Heraeus was aware of the facts supporting its claims by January 2009. The Third Circuit reversed in part, holding that Pennsylvania applies the rule of separate accrual to continuing trade secret misappropriations, Heraeus may sue for misappropriations that occurred within the three-year period before filing. The court agreed that alleged misappropriations more than three years before Heraeus filed suit are time-barred. View "Heraeus Medical GMBH v. Esschem Inc" on Justia Law
