Neptune Files for Revocation of Aker's Australian Patents

Neptune Files for Revocation of Aker's Australian Patents

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."
