Calcutta High Court Upholds Patent Term, Highlights Examination Delays

By Editorial Team

In a recent ruling, the Calcutta High Court upheld the 20-year patent term starting from the date of application, dismissing a writ petition challenging its constitutionality. The case shed light on the issue of delayed examination of patent applications, raising concerns among applicants.

Background of the Case

The case, Gunjan Sinha @Kanishk Sinha v. Union of India, questioned the efficacy of the 20-year patent term that begins from the date of filing but only becomes enforceable upon grant. The petitioners filed their patent application in 2005, but the patent was granted seven years later in 2012. During this period, the application was pending and published, leaving the applicants unable to take action against infringers. The petitioners argued that this waiting period infringed upon their statutory rights and constitutional guarantee of meaningful patent protection.

Court's Decision

The Single Judge bench found no inconsistency in Sections 11A(7) and 53 of the Patents Act, 1970, which define the patent term. The Division Bench, on appeal, ruled that the sections operated in tandem, providing interim rights before patent grant while ensuring compliance with international agreements. The court rejected claims of unequal treatment under Article 14 of the Constitution, stating that the sections applied uniformly to all applicants.

Examination Delays and Legal Imbalance

The case highlighted the issue of delays in patent examination, where the 20-year term continues to run even when patent rights are not fully enforceable. The lack of swift examination mechanisms can lead to inventors losing valuable years of protection, especially in fast-evolving industries. The court's failure to address Section 45(3), which prohibits infringement suits before publication, further compounds the issue.

Call for Administrative Reforms

The ruling underscored the need for administrative reforms within the patent office to streamline examination processes, reduce delays, and enhance accountability. Structural changes, such as increasing examiner capacity, adopting digital technologies, and establishing clear examination timelines, were suggested to address systemic inefficiencies.

Overall, the case emphasized the importance of ensuring timely patent examinations to uphold inventors' rights and provide meaningful patent protection. Without addressing administrative bottlenecks, the statutory 20-year patent term may remain symbolic, failing to deliver practical value to innovators.
