It is a much discussed topic at the moment:
Here's How TotalPatent answers The India content questions:
LexisNexis has about a third of a million patents from India in TotalPatent, all with English language Titles and about half with an English language Abstract. Although incomplete, currently the 22,000 Full Text (including the Description and Claims) records for India still represents the largest, searchable collection of IN data available on a commercial platform and is supported by roughly 50,000 PDFs and almost 100,000 front page and other
images. The data may be searched by a range of fields, including titles, abstracts, descriptions, claims, assignee and inventor names; as well as by various classification schemes including IPC, ECLA, ICO and IDT.
The bibliographic data is loaded onto our
systems every week and is updated in line with the publications on the site of the Intellectual Property India Office. The data is further enhanced by LexisNexis in several ways: Publication, Application and Priority numbers, as well as other relevant numbers, are all standardized, making the data more easily retrievable. In addition to the European Patent Office’s INPADOC family, LexisNexis calculates a Main and Extended patent family that covers authorities not currently available in the INPADOC collection. Other value added elements incorporated into the Indian data by LexisNexis include the creation of forward citations, the addition of various classification schemes as mentioned before and the production of “clipped images”.
