Under Section 124B(1) of the Patents Act, 1970, an appeal shall ordinarily be preferred within:

Section 124B(1) requires the appeal to be preferred within sixty days "from the date of receipt" of the order, though the appellate authority may entertain it later for sufficient cause. Three months is the period for appeals to the High Court under section 117A, and ninety days is the period for complying with the order under section 124B(6).
