Amarantus BioSciences Wins MANF Patent Challenge in Europe

SUNNYVALE, Calif., Nov. 20, 2012 /PRNewswire/ --Amarantus BioSciences, Inc. (OTCQB: AMBS), a biotechnology company developing new treatments and diagnostics for Parkinson's disease and Traumatic Brain Injury centered on its proprietary anti-apoptosis therapeutic protein MANF, today announced the Opposition Division of the European Patent Office upheld Amarantus Bioscience's European Patent relating to neurotrophic factor MANF, following opposition by rival Hermo Pharma OY of Finland.

The Opposition Division held that the Opponent's arguments did not prejudice the maintenance of the Patent as originally granted, with broad claims covering MANF and its derivatives. The Opponent had not contested the validity of the Patent on the basis of novelty or inventive step, but had objected to the broad scope of the claims. However, after due consideration of comprehensive legal and technical oral submissions from both sides, the Opposition Division rejected the Opponent's arguments and upheld the claims without restriction.

"This is a highly significant decision for Amarantus, after an extended period of uncertainty," said Marc Wilkinson PhD, European Patent Attorney of UK firm Avidity IP, representing Amarantus. "The Opposition Division's decision validates broad protection for MANF and derivatives across major European jurisdictions."
