The Indian Patent Act has strict rules relating to inventions pertaining to biological material which is not available to the public. Section 10 requires a complete description of such biological material along with details of any process using such material.
The Controller General has issued a notification in this regard that can be accessed here
Therefore in respect of patent applications which include biological material, it is important to ensure that the information should be provided in the specification itself at the time of filing or within three months from the date of filing. National Phase PCT Applications entering into India generally do not have this information and therefore applicants are well advised to include this information if not originally provided in the PCT application within three months of the filing of the application in India. This information can be included along with a request for amending the specification to include this additional matter.
