Executive Summary
Ciena Corporation challenged the deemed abandonment of its Indian patent application, which was issued by the Patent Office due to failure to respond to a First Examination Report (FER). The petitioner argued that this lapse was solely attributable to an inadvertent mistake made by their patent agent. The Delhi High Court agreed with Ciena, holding that an applicant should not suffer consequences for the bona fide errors of their legal representatives or agents. Consequently, the court set aside the abandonment letter and restored the application, granting a final opportunity to prosecute the patent.
