ABLYNX SUCCESSFULLY OPPOSES PATENT APPEAL CASE BY DOMANTIS (GSK)

GHENT, Belgium, Jan. 22, 2015 (GLOBE NEWSWIRE) -- Ablynx [Euronext Brussels: ABLX] today announced that it has been successful in opposing the appeal lodged by Domantis (now a member of the GlaxoSmithKline, GSK, group of companies) in 2010 against the decision by the Opposition Division of the European Patent Office to revoke Domantis' European Patent 1 517 921. As a result of the decision by the Board of Appeal, the Domantis patent will remain revoked in full (without further possibility to appeal).

The European Patent 1 517 921 relates to one specific technique for the half-life extension of immunoglobulin single variable domains. Now that the revocation of this patent has been confirmed in appeal, Ablynx and its partners remain free to apply such half-life extension techniques in their internal and partnered programmes, as Domantis has no granted patent claims that could possibly be invoked against the use of these techniques in Europe.

Dr Edwin Moses, CEO of Ablynx, commented:

"This is the result that we have always anticipated. One of the key features of our Nanobody® technology is the possibility for modular half-life extension to achieve the desired properties, such as the use in chronic versus acute indications. Today, we have already achieved two clinical proof-of-concepts in patients with rheumatoid arthritis with two Nanobodies that incorporate this half-life extension technology. From all the evidence available to us, our half-life extension technology, which is based on a serum-albumin binding Nanobody, outperforms that of GSK/Domantis. We are pleased that the Board of Appeal has now rejected attempts by Domantis to claim our proprietary techniques in their patents."

Ablynx was represented by Dr Joe Taormino and Dr Andreas Stefferl from the firm of Hoffmann-Eitle in Munich.
