Patent Opposition in India

Patent Opposition in India


The Patents Amendment Act, 2005 provided for a opposition system in India that allows both Pre and Post-grant opposition of the patent in order to ensure the product quality and validity of granted patents.

Although grounds for both pre and post-grant opposition are same, there are many differences regarding proceedings between your two systems. Additionally, in pre-grant opposition there is absolutely no remedy supplied by the work against your choice from the controller. While ‘any person’ can represent on paper for pre-grant opposition, just the ‘interested person’ detailing specific curiosity can document a post-grant opposition. Another essential difference getting that in case there is pre-grant opposition the work will not unequivocally supplies the patent applicant the chance to be noticed.

The lands for opposition outlined in the act primarily includes: (a) Wrongful obtaining from the invention (b) insufficient novelty (c) prior public knowledge or public use (d) Invention isn’t patentable (e) Invention is anticipation having regard to the data, oral or elsewhere, available within any nearby or indigenous community in India or somewhere else etc.

Pre-grant opposition

The pre-grant opposition is manufactured by method of ‘representation’ towards the Controller of Patents any moment following the publication of the application form but before grant supported with a statement and evidence, if any, plus a obtain hearing if so desired. After taking into consideration the representation, distribution and hearing the celebrations (if requested), the controller concurrently either rejects the representation and give the patent or acknowledge the representation and refuse the give of patent typically within a month from the day of conclusion of the proceedings. On concern, if the Controller is usually of the opinion that the application form for patent ought to be refused or needs amendment, he provides see towards the applicant to which applicant must reply within 90 days time from your date from the see. Nevertheless, the Controller shall consider such representation only once a obtain study of the application continues to be filed.

Post give opposition

The post grant opposition is manufactured by ‘notice of opposition’ from the opponent within twelve months from the time of publication of grant in prescribed form towards the Controller plus a written statement aiming the type of his/her interest, the reality which he/she bases his/her case, the relief that he/she seeks and evidence (if any) and providing a copy thereof towards the patentee also. The Opposition Table examines the see of opposition and ahead a written report within an interval of 90 days from the day which the files had been forwarded to it. The examiner that has handled the patent software during the grant is usually disqualified from being truly a member. Upon getting the see, the Controller constitutes an ‘Opposition Table’ comprising three users and among the associates nominated as Chairman.

If the patentee really wants to contest the see of opposition, he/she leaves the reply declaration aiming fully the lands where the opposition is contested and proof within an interval of 8 weeks in the date of receipt from the opponent’s written declaration and see and in addition delivers towards the opponent a copy thereof.

On conclusion of display of proof and after getting the suggestions of Opposition Plank, the Controller shall repair a time for hearing and present the celebrations a see of no less than 10 times of such hearing.


The brand new integrated opposition system in India has suitably addressed the post TRIPS concerns from the generic pharmaceutical industry about the increase in the amount of grant of several false patents. Furthermore, a pre-grant opposition may subsequently document a post-grant opposition following the patent offer hence complicating the situation for the patent applicant. Nevertheless, the patent candidates are actually at the chance of multiple pre-grant oppositions submitted by the competition as part of their business technique resulting in continuous and repeated opposition proceedings and therefore causing a hold off in the offer from the patent. Alternatively, Post offer opposition continues to be well known as its proceeding acts the passions of both patent applicant and opposition.
