working statement of patents in India, working statement of patents, form 27 in India

Filing annuity fees to maintain the legal status of granted patent is important. However in India, after a patent is granted patentees in India need to provide information regarding the working of patented invention on commercial scale in India in form 27, within three months of end of each year. So the deadline date to file working statement of patents (form 27) is before 31st March 2017. Even if the granted patent in India is not manufactured or offered for sale, the patent applicant need to furnish the information by filing Form 27.

For example, if the patent is not manufactured or offered for sale the reason of non-working should be mentioned in detail. If the patent is granted in medical and pharmaceutical sector, the reason for non-working could be that the patent has not received FDA regulatory approval for use on humans and is subject of ongoing clinical trials to obtain such regulatory approval (sample reason).

Filing of Form 27 is a requirement under Section 146 (2) of The Patents Act, 1970

Section 146 (1) of patent act provides power to controller to ask for information from a patentee at anytime during the continuance of patent by notice in writing. The patentee or a licensee (exclusive or otherwise) has to provide information related to working of an invention on a commercial basis to controller in the form 27. The time period to furnish the working details is within two months of such notice by controller.

Section 146 (2) of patent Act states:

every patentee and every licensee (whether exclusive or otherwise) shall furnish in such manner and form and at such intervals (not being less than six months) as may be prescribed statements as to the extent to which the patented invention has been worked on a commercial scale in India.

Therefore, both patentee and licensee have to submit working data of invention in India to the controller. The controller has an authority to publish the data regarding statements by patentees & license holder.

What data should be provided in Form 27 for working of patents in India?

The most important point is whether the patented invention has been worked or not worked?

  • if not worked, the reasons for not working and the steps being taken for the working of the invention.
  • if worked, the quantum and value (in rupees) of the patented product?
    • Is it manufactured in India;
    • Imported from other countries along with the details of each country;
    • The number of licenses and sub-licenses granted during the year;
    • Whether the public requirement has been met, at a reasonable price either partly, adequately or to the fullest extent?

What happens to Patents which are “not working” in India?

The non-working of a patented invention on a commercial scale in India makes the patent susceptible to compulsory licensing under Indian Patent law. Earlier in the case of Natco v. Bayer, the patent office noticed that the Bayer did not import the drug at all in 2008. However, the pharma company started importing the drug in small quantities in 2009 and 2010. Natco applied for a compulsory license under Section 84 of the Indian Patent law which was then granted by the controller and upheld later by the Bombay High Court.  One of the conditions of  Section 84 is that the patent should have ‘not worked in the territory of India’. If the Controller is satisfied, he may grant the applicant a non-exclusive compulsory license for the balance term of the patent. Natco saw the opportunity that Bayer was not making the drug accessible to patients.

Protection to unused patents would result in economic barony or empire. Douglas, J. quoted Hamilton, Patents and Free Enterprises (1941) (p. 161).

It is common practice to make an invention and to secure a patent to block off a competitor’s progress. By studying his ware and developing an improvement upon it, a concern may ‘fence in’ a rival, by a series of such moves it may pin the trade enemy within a technology which rapidly becomes obsolete. As often as not, such maneuvers retard, rather than promote, the progress of useful arts. Invariably their effect is to enlarge and to prolong personal privilege within the public domain.

In , Sandeep Jaidka vs Mukesh Mittal & Anr. on 9 May, 2014 there was no material placed on record to show that the plaintiff  had actually used the patented invention in India. Information from FORM 27 filed by the patentee himself before the Patent Office disclosed complete non-use of the patented invention.

Non-user of the patent by the patentee is a ground for refusing injunction

The non-user of the patent by the patentee is a ground for refusing injunction. A learned single Judge of the Delhi High Court in N.R.D. Corporation of India v. D.C. and G. Mills Co., refused injunction on the ground of non-user by the plaintiff-patentee. To a like effect is the decision of the Calcutta High Court in Boots Pure Drug and Co. (India) v. May & Baker Ltd., (1948) 52 Cal WN 253 which was followed by the Madras High Court in Manicka Thevar v. Star Plough Works.

It is advisable to Patentees & Licensees to file form 27 on a yearly basis to avoid future repercussions.

What is the repercussion of filing false information in working statement of Patents (Form 27)?

How to analyse the data generated from Form 27?
