Estar Technologies Ltd. ("Estar"), a world recognized developer and manufacturer of innovative medical technologies in the biologics and platelet rich plasma (PRP) fields for the treatment of damaged soft and hard tissue, filed a notice of opposition requesting the European Patent Office (EPO) to completely revoke European Patent No. 2,073,862 B1 in the name of Antoine Turzi, exclusively licensed to Regen Lab SA. If successful, the opposition will lead to the complete invalidation and revocation of Regen Lab's patent in all 32 designated contracting states of the EPO.

“This patent describes a blood separation method commercially available and published in industry and academic studies for over 30 years,” said Aaron Esteron, CEO and founder of Estar Technologies Ltd and one of the pioneers in the blood separation field. “We strongly believe that Estar’s products do not infringe Regen Lab's patent, it does not impact our ability to sell our products,” he added. “Our view is that the opposition we have filed at the EPO clearly demonstrates that the patent does not meet the requirements of the European Patent Convention and that, consequently, the patent will be revoked in its entirety,” concluded Mr. Esteron.
