LAVAL, Quebec, Dec. 21, 2012 (GLOBE NEWSWIRE) -- Neptune Technologies and Bioressources Inc. (Nasdaq:NEPT) (TSX:NTB), (" Neptune"), the pioneer in the krill oil industry, which holds a vast international patent estate covering krill oil compositions and methods of use, announces that it has filed for the revocation of all of Aker Biomarine ASA's Australian patents before the Federal Court. More specifically, Neptune is seeking a declaration that all the claims in Aker's patents, namely the standard patent No. 2008231570 and the innovation patents Nos. 2012101332, 2012101333, 2012101334 and 2012101335 (the " Aker Patents") are, and at all materials times have been, invalid. The Aker Patents claim a krill oil composition and methods of extraction that lack novelty and are not patentable inventions. Neptune marketed its NKO ® krill oil product many years before Aker filed for these patents in Australia. "The method and the compositions claimed in the Aker Patents are invalid and were obtained by false suggestion and misrepresentation, as stated in the documents filed by Neptune before the Federal Court of Australia," declared Neptune's Chief Global Strategy Officer, Dr. Tina Sampalis. "Neptune is the pioneer in the krill oil industry and, as such, we must protect our clients and our pharmaceutical subsidiaries, and ensure that invalid patents are not used to threaten Neptune's business partners. We are confident that the Federal Court of Australia will find that the Aker Patents are invalid." About Neptune Technologies & Bioressources Inc.
