Dispatched Is Not Delivered: Deemed Abandonment of Patent Application Set Aside

Summary

Tetra Technologies, Inc., a United States company, saw its Indian national phase patent application treated as abandoned after the Patent Office said it had emailed a First Examination Report that the applicant never received. The Delhi High Court held that deemed abandonment of a patent application under Section 21(1) of the Patents Act presupposes effective communication of the report at the address for service. It found that proof of dispatch, a system-generated intimation carrying a testing disclaimer, and stock replies could not stand in for delivery or a hearing. The ruling matters because it ties a harsh statutory consequence to demonstrable communication, which applicants and patent agents can invoke when official emails go missing.

Background

The deemed abandonment of a patent application in India turned on an email that the applicant says never reached it, and that the Patent Office could not prove it had delivered.

Tetra Technologies, Inc. (“Tetra Technologies”), a United States company, entered the Indian national phase of PCT/US2018/057202 on 11 May 2020 as Application No. 202017019804. Its Form 1 listed a New Delhi postal address and an email address. The application was published on 14 August 2020, and Tetra Technologies filed a request for examination in Form 18. The Patent Office, Mumbai, acting through the Controller of Patents and Designs (“Patent Office”), says it emailed the First Examination Report (“FER”) on 28 October 2021. No reply followed, so the Patent Office treated the application as abandoned under Section 21(1) of the Patents Act, 1970 (“Patents Act”) by a decision of 29 December 2022, after the Covid-19 relief period ended on 28 February 2022.

Tetra Technologies found out on 25 April 2023 from the official portal. Its patent agent then wrote to officials through November 2023 and received standard replies that the FER was “successfully sent”. The agent raised the grievance at Open House sessions in early 2024 and, on 5 March 2024, filed a petition in Form 30 seeking reissue of the FER. That petition stayed undecided, so Tetra Technologies filed a writ petition before the Delhi High Court, which ruled on 6 October 2026.

Issues

1. 1. Whether deemed abandonment of a patent application under Section 21(1) of the Patents Act can stand when the FER was not effectively communicated to the applicant at its address for service under Rules 5 and 6 of the Patent Rules.
   2. Whether dispatch of the FER by email under Rule 6(3) is conclusive proof of receipt, read with Rule 6(5).
   3. Whether a system-generated email that merely intimates an FER and links to the INPASS portal, with a disclaimer that it is under testing, amounts to valid communication.
   4. Whether leaving the Form 30 petition undecided, without a hearing, breached natural justice under Section 80 and Rule 129.

Tetra Technologies’ Arguments

• • The FER never reached Tetra Technologies or its agent, and inbox screenshots for 23 to 30 October 2021 showed no such email.
  • Abandonment requires a conscious act showing intent to give up the application, a point drawn from Ferid Allani v. Union of India (2008 (37) PTC 448 (Del.)), and Tetra Technologies had filed on time and sought examination.
  • The Patent Office offered no proof of delivery, only an internal IT email dated 11 May 2023 that surfaced long after the decision.
  • The Form 30 petition of 5 March 2024 specifically raised non-receipt, yet drew only stock replies and no hearing, which offends the audi alteram partem principle.

Patent Office’s Arguments

• • Under Rule 24B(5), an applicant has six months from the first statement of objections to put the application in order, extendable by three months on a Form 4 request filed before expiry, and Rule 138 bars any further extension.
  • The IT Division’s database shows the FER went out on 28 October 2021 to the email address Tetra Technologies furnished, which Rule 6(3) permits as authenticated electronic communication.
  • No reply was filed, so deemed abandonment followed by operation of Section 21(1), and the decision was taken only after the Covid-19 period had passed.
  • Relying on Telefonaktiebolaget LM Ericsson v. Lava International (2010:DHC:1425), the Patent Office argued that courts should not interfere with abandonment so long as the FER was issued.

Court’s Observations and Analysis

A legal fiction must stay within its purpose

The court noted that Section 21(1) creates a legal fiction, and that such a fiction must be confined to the purpose for which the legislature created it. The court held that deemed abandonment of a patent application operates only after the first statement of objections has actually been forwarded to the applicant at its address for service. The court observed that abandonment ordinarily signals a conscious act, and that the Patent Office cannot manufacture that intent from silence when the applicant never learned of the report.

The court further observed that the passage in Ericsson relied on by the Patent Office presupposes an FER that did reach the applicant. The court reasoned that the decision gives the Patent Office no shelter where receipt is seriously doubted.

Dispatch is not delivery

The court stated that Rule 6(3) allows authenticated electronic communication and treats the date of dispatch as the date of communication. The court found, however, that Rule 6(5), which lets the Controller condone delay in a communication reaching a party, shows that dispatch cannot be conclusive of receipt. The court opined that Tetra Technologies had furnished a valid postal and email address, produced inbox screenshots for the relevant week, and faced a Patent Office that produced no delivery proof.

The court noted that the internal IT email of 11 May 2023 proved only that a message was sent, and the court observed that it surfaced long after the abandonment decision.

A courtesy email is not the report

The court found that the system-generated email merely told the applicant that an FER existed and pointed to the INPASS portal. The court noted that the email carried a disclaimer that it was under testing and not valid for legal proceedings. The court held that such a message cannot alone justify deemed abandonment of a patent application, and the court reasoned that the Patent Office could have posted the FER or sent it again once non-receipt came to light.

The court observed that merely uploading a document to a website does not necessarily amount to notice.

Silence on the Form 30 petition

The court held that the scheme of the Patents Act and Patent Rules gives applicants extensions and a meaningful chance to respond, which reflects natural justice. The court noted that the Form 30 petition of 5 March 2024 expressly raised non-receipt and sought reissue of the FER, yet the record showed no consideration, decision or hearing. The court observed that Tetra Technologies entered the national phase on time, sought examination and pursued the matter promptly, conduct the court found inconsistent with any intent to abandon. The court acknowledged its own caution against reviving applications lightly, and it clarified that this case turned on the absence of effective communication of the FER.

Findings

In view of the observations and the arguments presented by both the parties, the Delhi High Court held that:

• • Deemed abandonment of a patent application under Section 21(1) requires effective communication of the FER to the applicant at its address for service.
  • Dispatch of an FER by email under Rule 6(3) does not conclusively prove receipt, and a system-generated intimation carrying a testing disclaimer cannot justify abandonment.
  • The Patent Office acted without notice or hearing, and the stock replies to the Form 30 petition did not cure that defect.
  • The decision treating Application No. 202017019804 as abandoned is set aside, and the application stands revived on the Patent Office’s records.
  • The Patent Office must furnish a copy of the FER dated 28 October 2021 within one week to Tetra Technologies’ patent agent and to the postal and email addresses for service, or any other address Tetra Technologies specifies.
  • Tetra Technologies has eight weeks to reply to the FER, after which the Patent Office must process the application expeditiously.
  • The court expressed no view on patentability, and the directions are fact-specific.
