Novogen's European Patent Claims Upheld

Novogen Limited, an Australian company was granted a patent in 2004 for the use of isoflavone phytooestrogen extracts of soy and clover. Archer Daniels Midland Company (ADM) holds the exclusive licence to the patent for isoflavones derived from soy, covering the entire global market except Australia and New Zealand.

Novogen and ADM believe the protection of intellectual property is a fundamental step in the development of high-quality nutritional supplements, and both companies will continue to maintain and protect their intellectual property.

At a hearing of the European Patent Office (EPO) in Munich, ending 8 July, 2009, the Opposition Division of the EPO agreed on claims for the Novogen Isoflavone Patent. In making the decision, the Opposition Division found that the subject matter of the patent claims were both enabled and exhibited an inventive step over the prior art. Importantly, the upheld claims largely reflect the claims of the original patent granted by the European Patent Office in 2004.

The Upheld Claims are:
1. The use of an isoflavone phyto-oestrogen extract of soy or red clover, wherein the isoflavone phyto-oestrogen extract comprises isoflavones selected from genistein, daidzein, biochanin A or formononetin, for the manufacture of a medicament for administration in unit dosage form which is a tablet or capsule for administration of isoflavone phyto-oestrogens in an amount from about 20 mg to 200 mg per day, optionally where the amount is 50 mg to 150 mg, for the treatment of pre-menstrual syndrome or symptoms associated with menopause.
2. A use as claimed in claim 1, wherein the isoflavone phyto-oestrogen comprises genistein and/or biochanin A: daidzein and/or formononetin, present in a ratio of from about 1:2 to 2:1.
3. A use as claimed in claim 1 or claim 2, wherein administration of the medicament is administered at least daily over a period of at least a month.

For more than twenty years, the EPO has adopted and approved the above form of claim ("...use of product x for the manufacture of a medicament for the treatment of ....."). In such cases, where there is a health benefit, the EPO and European patent law does not concern itself with the precise form of the administered product. European patent law regards what is administered as a "medicament" in a general sense.

A recent court decision by the Vienna Commercial Court reinforces European patent law, that food supplements are not excluded by the term medicament. The Court found a red clover isoflavone menopause product, Vitalady, infringed the Novogen patent. The court granted a provisional injunction against Vitalady accepting that a nutritional food supplement can be considered a medicament under European patent law.

The upheld claims from the Munich hearing therefore cover the use of nutritional supplements and food supplements for the stated treatment purposes.

The upheld claims refer to the isoflavones genistein, daidzein, biochanin A and formononetin. The isoflavones can also be supplied in a glycoside form. The glycoside isoflavones are converted in the gut to the aglycone form.

Novogen and ADM are delighted that, despite very intensive objections and after exhaustive consideration, the EPO has found that the Novogen patent is justified. The EPO decision will encourage further innovative research into food supplement products and further the development of original thinking about food supplementation to enhance human health.

Craig Kearney, General Manager Novogen Consumer Healthcare, said, “The EPO finding vindicated years of Novogen research and development and encourages our Company to further our R&D work into isoflavones and isoflavonoids for the benefit of consumers, health care professionals and Novogen’s business partners”.

Janice Binger, President, ADM Natural Health and Nutrition said, “We’re pleased with the EPO decision and look forward to working with the supplements industry to help drive growth in the market for soy isoflavones in a way that honours the hard work and intellectual property necessary for continued product development.”
