Nutratech Settles Patent Infringement Lawsuit

WAYNE, N.J., October 7, 2004 – Nutratech, Inc. – a research-based nutraceutical ingredient supplier – announces the settlement of their patent infringement action against AMAX NutraSource, Inc. (Amax), an Oregon Corporation, in the United States District Court for the District of Oregon. This action asserted U.S. Patent Nos. 6,224,873 and 6,340,482 and was based on the sale of Citrus aurantium material for weight loss purposes. The lawsuit has been dismissed, and the terms of the parties’ settlement are confidential and cannot be disclosed by either party.

Zhishin LLC is the owner of U.S. Patent Nos. 6,224,873; 6,316,499; 6,340,481; and 6,340,482, which are exclusively licensed to Nutratech. These patents relate to the use of Citrus aurantium, bitter orange or citrus extracts for, but not limited to:

• stimulating thermogenesis
• reducing weight loss
• increasing lean muscle mass to total body mass
• improving athletic performance and
• suppressing appetite

“By purchasing Advantra Z®, Nutratech’s customers can utilize these claims, subject to their attorney’s comments and/or approval, on their product’s label and marketing support material,” states Bob Green, one of the principals of Nutratech. “This gives Nutratech’s customers a marketing advantage over their competition that may be purchasing generic Citrus aurantium from companies like Amax and therefore, cannot legally make these claims.” Green adds.

Most of the research on Citrus aurantium has been conducted using Advantra Z®, which utilizes optimal harvesting techniques and a proprietary extraction process to produce a truly unique synergistic amine composition. This complete composition of five synergistic adrenergic amines: synephrine, n-methyltyramine, hordenine, octopamine and tyramine is responsible for delivering the applications protected by the aforementioned series of patents and the positive results found in the research.

“And it’s this time and cost intensive investment that we want to make sure benefits our customers and not their competitors who choose to use scientifically unsupported generic Citrus aurantium material in their diet and sports nutrition products while riding the coat tails of our significant investment in research and product development,” contends Bob Green.


Nutratech, Inc. with headquarters in Wayne, NJ provides innovative, proprietary and patented nutraceutical ingredients with efficacy claims that are supported by sound scientific research.
