Can I access the documents in the file of an Indian patent application?

Yes. Once an application has been laid open, anyone can file a written request for file inspection and obtain certified copies upon payment of the requisite fee.

Alternatively, provided the relevant records have been digitised, you can download the documents in the file from the Indian Patent Office's free InPASS website.
