USPTO Issues Positive Decision That Triggers Royalty Payments to Neptune

LAVAL, Quebec, March 23, 2015 (GLOBE NEWSWIRE) -- Neptune Technologies & Bioressources Inc. ("Neptune") (Nasdaq:NEPT) (TSX:NTB) and Acasti Pharma Inc. ("Acasti") (Nasdaq:ACST) (TSX-V:APO), announce that on March 23, 2015 the Patent Trial and Appeal Board (PTAB) of the US Patent and Trademark Office (USPTO) issued a favourable decision, confirming the validity of certain claims in Neptune's '351 patent (U.S. Patent: 8,278,351) and triggering royalty payments to Neptune.



"This is a significant milestone that triggers the payment of ongoing royalties to Neptune by Aker and Enzymotec, based on their sales of licensed krill oil products in the US," highlighted Jim Hamilton, President and CEO of Neptune. "The decision clearly supports the validity and enforceability of Neptune's '351 composition of matter patent. Now that the positive decision has been rendered, we can turn our attention to building the industry and growing the krill oil market."

"Our intellectual property (IP) is a fundamental and valuable asset," highlighted Benoit Huart, Director Legal Affairs at Neptune. "The positive decision preserves strong IP protection for both our nutraceutical and pharmaceutical businesses and substantiates our IP procurement and enforcement strategy. Aker and Enzymotec may appeal the decision. Regardless, the strength of our patent estate has once again been recognized. We will continue to enforce and build upon it to ensure we have long lasting and comprehensive protection, while preventing others from importing into and selling infringing products wherever we have valid patents."

Background

On December 17, 2013 and April 27, 2014, Neptune announced that it had successfully concluded a settlement and license agreement with Aker and Enzymotec, respectively. Neptune granted a world-wide, non-exclusive, royalty-bearing license to both parties to market and sell nutraceutical products in the licensed countries. Pursuant to the terms of these settlements, royalty levels in the US depended on the outcome of an inter partes review at the PTAB of certain claims from Neptune's '351 patent. In light of the PTAB's decision, Aker and Enzymotec will be obligated to make royalty payments to Neptune based on their sales of licensed krill oil products in the US.

Under the terms of the settlement agreement with Enzymotec, their royalty obligations in Australia were similarly dependent on the outcome of a potential request with the Australian Patent Office for a review of certain claims of Neptune's Australian composition of matter patent (AU 2002322233). As Neptune expected, Enzymotec decided to pursue a patent reexamination, and the review recently commenced. In Australia, once a patent re-examination request is filed the Patent Office must conduct it. There are no mechanisms by which the patentee (Neptune) can attempt to prevent this procedure. Neptune has until the end of March 2015 to respond to the reexamination report recently issued by the Australian Patent Office. The reexamination in Australia has no impact on Neptune's license agreements with Rimfrost and Aker.

Acasti focuses on the research and development of safe and therapeutically effective compounds for highly prevalent atherosclerotic conditions, such as cardiometabolic disorders and cardiovascular diseases. Its lead prescription drug candidate is CaPre®, a purified high omega-3 phospholipid concentrate derived from Neptune krill oil being developed to address the prevention and treatment of cardiometabolic disorders, including hypertriglyceridemia, which is characterized by abnormally high levels of triglycerides.

About Acasti Pharma Inc.

Acasti is an emerging biopharmaceutical company focused on the research, development and commercialization of new krill oil-based forms of omega-3 phospholipid therapies for the treatment and prevention of certain cardiometabolic disorders, in particular abnormalities in blood lipids, also known as dyslipidemia. Because krill feeds on phytoplankton (diatoms and dinoflagellates), it is a major source of phospholipids and polyunsaturated fatty acids ("PUFAs"), mainly eicosapentaenoic acid ("EPA") and docosahexaenoic acid ("DHA"), which are two types of omega-3 fatty acids well known to be beneficial for human health. CaPre®, currently Acasti's only prescription drug candidate, is a highly purified omega-3 phospholipid concentrate derived from krill oil and is being developed to help prevent and treat hypertriglyceridemia, which is a condition characterized by abnormally high levels of triglycerides in the bloodstream. ONEMIA®, a medical food and currently Acasti's only commercialized product, is a purified omega-3 phospholipid concentrate derived from krill oil with lower levels of phospholipids, EPA and DHA content than CaPre®.
