In the news since 10 July 2026

Why in news
On 9 July 2026, CSIR and IP Australia signed an agreement giving IP Australia access to CSIR-TKDL at the 3rd India–Australia Annual Summit in Melbourne.
What it is
The Traditional Knowledge Digital Library is an Indian database of documented traditional knowledge. It works as a prior art source so that patent examiners abroad can reject patents on knowledge already in the public domain. It protects knowledge defensively; it does not give any owner rights over it.
Origin
TKDL was set up in 2001 by CSIR together with the Ministry of AYUSH.
Content and languages
It holds over 5.2 lakh formulations and practices from Ayurveda, Unani, Siddha, Sowa Rigpa and Yoga, in five international languages.
Access
With Australia, eighteen patent offices now have access under Non-Disclosure Agreements.
Impact
Prior art from TKDL has led to more than 375 patent applications being revoked, rejected, amended, withdrawn or abandoned.
Purpose of the Australia deal
IP Australia can use TKDL to find prior art when examining patent applications under Australian law.

Don’t confuse with TKDL vs Biological Diversity Act benefit sharing: TKDL is a defensive prior art database against wrongful patents. The Biological Diversity Act, 2002 regulates access to biological resources and sharing of benefits.

Science and technology: 57 Prelims questions since 2013; most test the concept behind the news, not the news itself. In Mains, 12 news-triggered questions.

Worth revising until Prelims 2028: most news questions come within two years of the event.
