India’s Traditional Knowledge Digital Library (TKDL): A powerful tool for patent examiners

Data is reproduced from EPO website. On 2 February 2009 the Indian government granted access to its Traditional Knowledge Digital Library (TKDL), a unique database that houses the country’s traditional medical wisdom, to examiners at the European Patent Office (EPO).

EPO examiners will use the extensive database to prevent attempts at patenting existing traditional knowledge, a practice described as “bio-piracy”.

The co-operation between India and the EPO comes at a time when many countries are struggling to protect traditional and respected knowledge against exploitation, primarily in the pharmaceutical sector….

A unique encyclopaedia: The TKDL is the result of a US$ 2 million joint project between five Indian government organisations, including the Council of Scientific and Industrial Research (CSIR) and the National Institute of Science Communication and Informative Resources (NISCAIR).

Under the direction of Vinod Kumar Gupta, the head of NISCAIR, more than 150 experts in traditional medicine, law and computer science spent the past ten years arranging and classifying the TKDL.

Highlights of the vast database include:

§  54 authoritative textbooks on ayurvedic medicine

§  Nearly 150,000 ayurvedic, unani and siddha medicines

§  Over 1,500 physical exercises and postures in yoga, more than 5,000 years old.

Patent Visualization Tool

XLUS is web-based software that can visualize massive numbers of patent searches and analysis results in landscape thememap.

In order to illustrate the similarity and technological relationships between patents, XLUS produces a radar chart in addition to an ordinal patent list.

XLUS’s core technologies consist of natural language processing, data informatics, visualization and easy expression, and IP knowledge and analysis. XLUS has great potential to improve search productivity for planning of development strategies, as well as patent acquisition strategies.

Indian Patent full text

India is one of the leading destinations for business hubs. A lot of companies are protecting their Intellectual Property (patent) in India.  Indian Patent Office has made the Patent Database public to view the Patents. The searching of Indian Patents is very restrictive as I have posted about it in another post.  The patent office has tried to make the full text of Indian patents available to public free of cost. This facility is available to the patent number from 1 – 1,69,500 (patent applications filed and accepted for grant mostly prior to 1992).

Regrettably till date, the full texts of recent patents are not available to public freely. These can only be obtained from Indian Patent Office by payment basis.



Hubmed is an alternative website for mining PubMed database. It’s worth to try once. The features of the databases are as follows:

  • Daily updates of search results via web feeds.
  • Quick access to searches with a Firefox search plugin or a HubMed bookmarklet (drag to your browser’s bookmarks toolbar).
  • Export citations in RIS, BibTeX, RDF and MODS formats, or directly to RefWorks.
  • Unzip HubMed’s import filter into Endnote’s Filters folder for direct import into Endnote, or install the RIS Export plugin for direct import into ProCite, RefMan and older versions of Endnote.
  • Use the Citation Finder to convert reference lists from PDFs into search results.
  • Create lists of closely related papers using Rank Relations, then visualise and browse clusters of related papers using TouchGraph (requires Java).
  • Graph occurrences of keywords in published papers over time.
  • Tag and store annotated metadata for articles of interest.
