WILMINGTON, Dela.—DNP International Co. Inc. will no longer import, export, supply, make, use, sell or distribute beta-alanine or any product derived from it, after several years of litigation with Natural Alternatives International Inc. (NAI) and Compound Solutions Inc. (CSI).
NAI owns a series of patents related to beta-alanine, and CSI is its licensed distributor. In September 2011, NAI and CSI sued DNP in Delaware federal court for unfair competition. In December 2011, DNP asked the court to declare three NAI patents related to beta-alanine invalid. DNP filed a new case in January 2012 seeking a declaration that a NAI patent also related to beta-alanine was invalid. NAI counterclaimed.
The parties have agreed to dismiss all claims and counterclaims without prejudice.
