In India it is obligatory on part of the patentee and licensee (whether exclusive or otherwise) to supply information regarding the extent to which the patented invention has been commercially worked in India. The controller also has the power to call for such information at anytime during the continuance of the patent. Failure to furnish such information creates a presumption of non-working and may attract a fine.

Additionally, intentional furnishing of the false information is an offence punishable with imprisonment for up to six months and or fine or both. Accordingly, working of patents statements are necessary to submit with the Indian Patent Office with respect to every calendar year within three years of the end of each year.
