THE INTERNATIONAL DEBATE ON TRADITIONAL KNOWLEDGE AS PRIOR ART IN THE PATENT SYSTEM: ISSUES AND OPTIONS FOR DEVELOPING COUNTRIES

The document argues that the patent system often fails to prevent 'bio-piracy' because traditional knowledge is rarely considered prior art during the examination of patent applications. It analyzes the definitions of prior art in the US, Japan, and Europe, and evaluates the Patent Cooperation Treaty (PCT) as a mechanism for improving searches. The author recommends requiring patent applicants to disclose the source of traditional knowledge and evidence of prior informed consent, while suggesting the creation of standardized, linked databases to make public domain traditional knowledge accessible to patent examiners.

• The patent system has been criticized for failing to prevent the misappropriation of traditional knowledge, leading to the granting of patents for inventions that do not meet novelty or inventiveness requirements when compared to the traditional knowledge they were derived from.
• High-profile cases of 'bio-piracy' include the Turmeric Patent (US Patent No. 5,401,504), the 'Neem' (Azadirachta indica) Patents, and the 'Ayahuasca' (Banisteriopsis caapi) Patent, where failures in prior art searches allowed questionable patents to be granted based on indigenous knowledge from India and the Amazon.
• Traditional knowledge is rarely recognized as prior art during patent examinations because it is often not codified in writing, is not systematically organized for examiners, and patent offices lack effective search tools to retrieve non-patent literature.
• Under the Patent Cooperation Treaty (PCT), oral disclosures or use are generally only considered relevant to an international search if they are substantiated by written disclosure.
• The author recommends that patent applicants be required to disclose if traditional knowledge is part of an invention, the source of that knowledge, and evidence of prior informed consent and equitable benefit sharing with source communities.
• To improve defensive protection, the author suggests integrating traditional knowledge periodicals, newsletters, and gazettes into the PCT's minimum documentation list and the Journal of Patent Associated Literature (JOPAL).
• The creation of traditional knowledge databases poses a risk to indigenous peoples, as codifying knowledge that is currently only available within specific communities may disrupt internal stability or eliminate the ability of communities to negotiate terms of use.
