Case Study

Sphaera Pharma Pvt. Ltd and Anr. Vs Union of India

In this case, Delhi High Court decided upon the issue of the limitation period for the examination of a patent application prescribed under the Patent Act 1970. The court once again decided on the validity of the extension of the prescribed period in filing a request for examination of a patent application.

In the case, Sphaera Pharma (petitioner) filed a patent application with the Indian Patent Office. As per the Act, the petitioner was also required to file a request for the examination – Form 18 of the patent application within 48 months from the date of filing the initial patent application. The petitioner had also filed Form 30 concerning the Patent Application so that the request for examination could be taken on record. However, the said request was not uploaded due to some technical reasons and as a result, the patent application was shown as abandoned under Section 11B of the Act. Thereafter, the petitioner filed a review petition for its application that wasn’t thought of by the bureau. The petitioner filed an official document petition before the Hon’ble city judicature for the restoration of the application. The petitioner contended that the Controller of Patents had the facility to increase the prescribed amount for filing a patent examination request, for one month. After critically examining sec 11B in conjunction with Rule 24B, the court command that there’s no scope for the thought of any application for the examination that is filed once the prescribed time from the date of filing of the application. The court rejected the petitioner’s rivalry concerning the facility of the Controller of Patent Act. Court command that plain reading of the act clearly shows that the facility of the Patent Controller to increase the prescribed amount doesn’t extend the prescribed amount underneath rule 24B. The Court took the respect to the judgment within the case of Nippon Steel Corporation v. Union of India[2011 (46) PTC 122 (Del)], wherein there was an error in entering the priority date of the patent. The relevant excerpt of the judgment states that,

“There is a logic to the time limits set out under the Act. The scheme of the Act and the Rules require time-bound steps to be taken by applicants for grant of the patent at various stages. The provisions of the Act and the Rules have to expressly reflect the legislative intent to permit relaxation of time limits, absent which such relaxation cannot be read into’ the provisions by a High Court exercising powers under Article 226 of the Constitution. In other words, this Court can’t accept the submission of the learned Senior counsel for the Petitioner that the time-limits under Section 11-B(1) of the Act read with Rule 24-B of the Rules, notwithstanding Section 11-B(4) of the Act, is merely directory and not mandatory. The wording of Section 11-B(4) of the Act underscores the mandatory nature of the time limit for filing an RFE in terms of Section 11-B(1) of the Act read with Rule 24-B of the Rules.”2

The Court discussed the Nippon case and clarified that the time limit prescribed under the act for filing patent examination is mandatory and can’t be relaxed in any nature.

The gist of this case is that the timelines stated in the Patent Act play an important role in the complete course of the patent. And if the applicant fails to file a request for examination or fails to respond in a prescribed period, due to any reason there is no recourse available to revive the case.

In this case, the High Court reaffirmed that the issue regarding the specified period for filing a request for examination of the patent application. The court states that the time limit of 48 months is mandatory and must be adhered to regardless of the delay caused due to any reason whatsoever. The time limits are there for a purpose and must be strictly followed by the applicant. However, if any problem arises because of the technical reason there must be some alternate method for the applicant for filing the request for examination of a patent application after the completion of the time specified in the act.
