Patent Infringement Settlements Reached

Neptune Grants a Royalty Bearing License on Its Patents

LAVAL, Canada, Oct. 2, 2013 (GLOBE NEWSWIRE) -- Neptune Technologies & Bioressources Inc. ("Neptune") (Nasdaq:NEPT) (TSX:NTB) and Acasti Pharma Inc. ("Acasti") (Nasdaq:ACST) (TSX-V:APO), a Neptune subsidiary, announce the conclusion of a settlement with Rimfrost USA, LLC ("Rimfrost"); Olympic Seafood AS; Olympic Biotec Ltd.; Avoca, Inc.; and Bioriginal Food & Science Corp. (collectively the "Settling Respondents") resolving the U.S. International Trade Commission's (ITC) investigation related to infringement of Neptune's composition of matter patents by the settling Respondents. The investigation was instituted earlier this year by Neptune and Acasti in a complaint filed with the ITC.

As part of the settlement, Neptune granted a world-wide, non-exclusive, royalty-bearing license to the Settling Respondents, allowing them to market and sell within the nutraceutical market products containing components extracted from krill. The Settling Respondents also agreed to pay Neptune an additional royalty amount due for the manufacture and sale of krill products prior to the effective license commencement date. As part of the settlement, Neptune agreed to dismiss a related patent infringement case against Rimfrost, Olympic Seafood AS and Avoca, Inc. filed in March, 2013 with the United States District Court for the District of Delaware. However, the exact terms and conditions of the settlements are confidential.

"It is our duty to protect our intellectual property (IP) and build value from our patents as they represent a key factor for our growth and advancement in the industry," highlighted Benoit Huart, General Counsel at Neptune. "Today's resolution with key industry players in the ITC investigation endorses the strength and validity of Neptune's IP and reflects our commitment to remain dedicated in its defense, as well as our desire to negotiate licensing agreements with our industry peers."

"Neptune and Acasti's intellectual property is a fundamental asset and an integral part of shareholder value creation for both our nutraceutical and pharmaceutical businesses," highlighted Mr. Henri Harland, President and CEO of Neptune and Acasti. "Together we offer very complementary strengths and we look forward to working in association with our new strategic industry partners to develop the krill market and to grow our respective businesses based on strong science and ethical standards."

"Owning and protecting strong IP in the industry is very important, particularly for the major players within the market," highlighted David Peele, President at Rimfrost USA. "We reached an agreement with Neptune that allows us to offer krill products in the USA and other markets based on the strength of Neptune's IP." 

"We look forward to working together with Neptune to further build the industry and grow the krill oil market, which will benefit us all," added Bjørnar Kleiven, Managing Director of Olympic Seafood AS. "We will now focus on the new synergies created through today's announcement to support overall consumer demand." 

To date, Neptune and Acasti have not reached a settlement with the remaining Respondents in the ITC investigation, Aker BioMarine AS; Aker BioMarine Antarctic USA, Inc.; Aker BioMarine Antarctic AS; Enzymotec Limited and Enzymotec USA, Inc. (collectively "Aker and Enzymotec").  Neptune will always remain steadfast in the defense of its IP.  The ITC is scheduled to commence an evidentiary hearing on December 10, 2013, and by March 17, 2014, the Administrative Law Judge is expected to issue an initial determination on the alleged violation.  Once the ITC makes a Final Determination, that decision will be immediately enforced, even if there is an appeal, and it could result in Aker and Enzymotec's krill products being banned from importation into the United States.
