Indian Patents Now Covered in Derwent World Patents Index

Apr 29, 2005

The Thomson Scientific unit of The Thomson Corporation announced that Derwent World Patents Index (DWPI) will now include Indian patents, both pre-grant applications and granted patents. The inclusion of Indian patents in DWPI follows the culmination of the government's long process of amending India's national patent laws to ensure they conform to Trade Related Intellectual Property Rights (TRIPS) norms. Indian patent coverage starts with data published December 4, 2004, so DWPI users will have access to all Indian patent documents issued since the new law took effect. By mid-year, Indian patent data will be available in DWPI within two weeks from publication.
