What looks like the final hurdle to the generics was cleared when the patent office’s Technical Board of Appeal revoked the last of the patents that Teva had received for Copaxone’s manufacturing process. Teva had contended in its patent applications that an improvement it had made in the glatiramer acetate synthesis process was unique enough to warrant patent protection.
The patent feud between Synthon and Teva was related to the use of the chemical hydrogen bromide (HBr) in the Copaxone manufacturing process. Teva had sued Sython in 19 European countries, maintaining that Synthon had infringed on its patents.
Although the Technical Board of Appeal has the name “board” in its title, it is actually a court, so it’s decisions are not just administrative actions but legal rulings.
Until the Technical Board of Appeal rulings, Synthon had lost all of the earlier legal rounds of the battle. The final board ruling revoked the last of Teva’s three so-called HBr patents on glatiramer acetate synthesis.
Synthon said in a press release that the Board of Appeal decision indicated that Teva’s earlier actions against it “lacked legal basis and were unjustified.”
While the legal battle was raging, Synthon had contested Teva’s efforts to obtain preliminary court injunctions to prevent it from making a generic version of Copaxone. It had also appealed injunctions that had already been handed down.
The Technical Board of Appeal decision means that all injunctions against Synthon will be lifted.
