Time limits for various actions while prosecuting a patent application and also for post grant procedures have been either specifically provided in the Patents Act or prescribed through the Patents Rules. These time limits are required to be followed strictly by every person concerned. Failure to adhere to the legally imposed time limits may turn out to be detrimental to the interests of the applicants, patentees or any other person interested. Other than few action or any proceedings, the time limits prescribed in the Rules for an action or any proceedings; may be extended by the Controller for a period of one month, if he thinks it fit to do so and upon such terms as he may direct.
