Tkdl Opposition Case-Law Abroad India
Introduction: TKDL and Patent Opposition
The Traditional Knowledge Digital Library (TKDL) is an Indian initiative that documents traditional knowledge, especially Ayurveda, Unani, Siddha, and Yoga remedies, in digital form in multiple languages. Its main purpose is to prevent “wrong patents” abroad, where foreign applicants try to patent Indian traditional knowledge.
TKDL has been instrumental in opposition proceedings in Europe, the USA, Japan, and Canada. When patent offices find prior art in TKDL, they often reject or revoke the patent application.
