Court Rules Mere System-Generated E-Mail Not Sufficient Proof of Communication; Directs Patent Office to Re-Serve First Examination Report and Revive Application
In a significant judgment dated October 6, 2026, the Delhi High Court quashed the decision of the Patent Office to treat Tetra Technologies, Inc.'s Indian Patent Application No. 202017019804 as deemed abandoned under Section 21(1) of the Patents Act, 1970. The Court held that the deemed abandonment could not be sustained because the First Examination Report (FER) was never effectively communicated to the petitioner, thereby violating principles of natural justice.
The petitioner, Tetra Technologies, had entered the national phase of its international patent application in May 2020 and furnished both a postal address in New Delhi and an e-mail address for service in its application. The Patent Office issued the FER on October 28, 2021, and claimed to have sent it via a system-generated e-mail to the petitioner's registered e-mail address. However, the petitioner denied receiving the FER or any communication regarding it.
The Court scrutinized the evidence and noted that the petitioner's email inbox records showed no receipt of the FER during the relevant period. Moreover, the system-generated e-mail itself carried a disclaimer stating that the information was "under testing" and "not valid for any legal proceedings." The respondents failed to prove that the FER was sent to the postal address or to provide any proof of delivery of the e-mail.
The Court emphasized that under Section 21(1) of the Patents Act and the Patents Rules, the period for putting an application in order for grant starts only when the first statement of objections (FER) is effectively communicated to the applicant at the address for service. Mere dispatch of an e-mail, without evidence of actual receipt, does not constitute effective communication. The Court further highlighted that abandonment requires a conscious act of the applicant indicating an intention to abandon the application. The petitioner's actions-filing the national phase application, requesting examination, and persistently pursuing the matter after learning of the abandonment-were inconsistent with any such intention.
The Court also observed that the Patent Office failed to provide an opportunity to the petitioner to respond to the FER, as the petition filed by the petitioner to seek re-issuance of the FER remained undecided and the petitioner was not heard. This violated the audi alteram partem principle enshrined under natural justice.
Accordingly, the Court set aside the decision treating the patent application as abandoned and directed the respondents to furnish a copy of the FER to the petitioner's patent agent at both the postal and e-mail addresses within one week. The petitioner was granted eight weeks to file a reply. The Court clarified that it had not expressed any opinion on the merits of the patent application and that the directions were issued considering the specific facts of the case.
This judgment reiterates the importance of effective communication in patent prosecution and safeguards the procedural rights of applicants under the Patents Act and Rules. It also underscores that the drastic consequence of abandonment cannot be imposed without ensuring the applicant has received proper notice and an opportunity to respond.
Bottom Line:
Patents Act, 1970 - Deemed abandonment under Section 21(1) cannot be sustained unless First Examination Report is effectively communicated to applicant at address for service - Mere system-generated e-mail dispatch, without proof of delivery, is insufficient - Non-receipt of FER violates principles of natural justice - Patent application directed to be revived and FER to be re-served.
