Every patentee or licensee of a granted patent in India is required to submit working status (statement) of the patent in India.The primary purpose of statement of working of a patent in India is to inform the Patent office that the patented invention has been made available to general public.

How much does it cost to file a statement for working of a patent in India?

Filing of statement of working provides the patent office with information relating to commercialization of the patented invention in the territory of India thereby preventing the non use of patented inventions.

According to Section 83 of Indian Patent act, ‘..patents are granted to make the benefit of the patented invention available at reasonably affordable prices to the public’ therefore every patentee and every licensee of a granted patent is required to file a statement as to the extent to which the patented invention has been worked on a commercial scale in India.

As per the said Section 83 of the Indian Patents Act, 1970, that patents are not granted ‘merely to enable patentees to enjoy a monopoly on a patented article’,1 but ‘to secure that the inventions are worked in India on a commercial scale and to the fullest extent that is reasonably practicable without undue delay’. Consistent with the goal of technology transfer, ‘the protection and enforcement of patent rights contribute to … technological innovation, … the transfer and dissemination of technology, to the mutual advantage of producers and users of technological knowledge, and in a manner conducive to social and economic welfare, and to a balance of rights and obligations’…If the patent is worked in India, then the statement must indicate quantum and value of the patented product. Further licenses and sub-licenses granted for the patent is also required to be submitted.

If the patent is not worked in India, the statement must indicate a reason for non-working of the patent in India.

If a patentee or licensee refuses or fails to furnish information required under Sec 146, the patentee or licensee will be punished with fine, which may extend up to Ten lakh rupees under Section 122(1)(b). Further, providing wrongful information or statement can impose the patentee/licensee to imprisonment up to six months or fine or both Section 122(2).

Section 146(2) of the Patent’s Act, 1970 requires patentees and licensees to submit a statement of commercial working of the invention (Form 27) to the Controller every year. Such statements can be published by the Controller General for public viewing.

Failure to submit information on statement of working is punishable and attracts a hefty fine which may extend up to Rs.10 lakh. Further according to Section 122, providing false information regarding working of an invention is considered as an offense and is punishable with imprisonment up to six months and a fine, or both.

If the working statement for the patent is not filed, then a penalty up to US$ 18,000 may be imposed on the patentee.

As the consequences of non-submission of the working statement can be severe, we recommend filing of the working statement before 31st of March each year.
