Eden Research plc, the agrochemical and encapsulation development company, announces that is has received notification from the African Regional Intellectual Property Organization (ARIPO) of its intention to grant a patent for the use of terpenes encapsulated in hollow glucan particles for killing insects and arachnids.

The Patent will be applicable across 15 ARIPO member states and these designated states have been notified of the decision to grant the patent.

The patent will be granted provided that the grant and publication fees are paid to ARIPO before the deadline of 15 June 2012 and subject to any objections raised before 15 September 2012.

About ARIPO

ARIPO was created in 1976 to promote the development of Intellectual Property laws appropriate to the needs of its members, establish common services and training schemes, assist its members in the acquisition and development of technology and the evolving of common views on Intellectual Property matters.

Membership of ARIPO is open to all member states of the African Union (AU) or of the United Nations Economic Commission for Africa (ECA).

The ARIPO member states where the patent will be applicable are: Botswana, The Gambia, Ghana, Kenya, Lesotho, Malawi, Mozambique, Namibia, Sierra Leone, Sudan, Swaziland, Uganda, United Republic of Tanzania, Zambia and Zimbabwe. The remaining member states: Liberia, Rwanda and Somalia became members of ARIPO after the patent application was filed.

Clive Newitt, Managing Director of Eden said, "The granting of this patent will be useful not only to our existing licensees, but also to other prospective licensees based in Africa. The granting of a patent in such a large and important area of food and crop production inherently adds real value and strength to Eden's intellectual property and business proposition."

Notes:

Eden is an early stage revenue company with intellectual property and expertise in encapsulation, terpenes and environmentally friendly technologies to provide naturally occurring solutions to the global agrochemicals industry, the animal health industry, and consumer products.

Eden's encapsulation technology harnesses the biocidal efficacy of naturally occurring chemicals produced by plants (terpenes) and can also be used with hydrophobic compounds both natural and synthetic. The technology uses yeast cells to deliver a slow release of natural compounds for agricultural and non-agricultural uses. Terpenes are already widely used in the food flavouring, cosmetic and pharmaceutical industries.

Historically, terpenes have had limited commercial use in the agrochemical sector due to their volatility, phytotoxicity and poor solubility. Eden's platform encapsulation technology provides a unique, environmentally friendly solution to these problems and enables terpenes to be used as effective, low-risk agrochemicals.

With leading consultants in their respective fields, the Company is developing these technologies through innovative research and a series of commercial production, marketing and distribution partnerships.

The Company has a number of patents and has a pipeline of products at differing stages of development targeting specific areas of the global agrochemicals industry. To date, the Company has invested in the region of £12m in developing and protecting its intellectual property. Revenues earned by the Company have been modest (2010: £172,000; 2011: £91,000) whilst the Company has concentrated on securing patent protection for its intellectual property, identifying suitable industrial partners and entering into licence agreements.

Eden was admitted to trading on AIM on 11 May 2012 and trades under the symbol EDEN.
