Introduction China has completed the most consequential rewrite of its Trademark Law in over a decade. On June 26, 2026, the 23rd Meeting of the Standing Committee of the Fourteenth National People's Congress adopted a comprehensive revision of the Trademark Law of the People's Republic of China — the fifth amendment since the law was first enacted in 1982, and the first substantive overhaul since the narrow 2019 revision. The revised law, comprising 87 articles across nine chapters (up from 73 articles in eight chapters under the outgoing law), will enter into force on January 1, 2027. Trademarks registered before that date remain valid. For brand owners, in-house counsel, and IP practitioners with China exposure, this is not a routine update. The revision touches registration standards, opposition timelines, well-known mark protection, damages calculations, and — perhaps most significantly — the treatment of bad-faith and speculative filings that have long troubled foreig...
Delhi High Court Restores Synertec's Patent Application: Patent Agent's Docketing Error Does Not Cost the Applicant Its Rights
Summary
In re: Synertec Pty Ltd v. Union of India & Anr., W.P.(C)-IPD 53/2025, the Delhi High Court has restored Indian Patent Application No. 202217030233, filed by Australian company Synertec Pty Ltd for a system and method of vaporising liquefied natural gas, after the application had gone "deemed to be withdrawn" under Section 11B(4) of the Patents Act, 1970 for non-filing of the Request for Examination (Form 18) within the statutory 48-month window. The Court held that the lapse was caused entirely by the Petitioner's patent agent misstating the deadline, not by any intention on Synertec's part to abandon the invention, and directed the Patent Office to restore the application and permit Form 18 to be filed within two weeks.
Background: How the Application Came to Be "Deemed Withdrawn"
Under Section 11B read with Rule 24B of the Patents Rules, 2003, an applicant must file a Request for Examination within 48 months of the priority date, failing which the application is treated as withdrawn by operation of law under Section 11B(4) — no separate order from the Controller is required.
For Synertec's application, that 48-month deadline (as it used to be before 2024 Amendment of Patent Rules, now deadline is 31 months) fell on 27 November 2023. However, the Petitioner's Indian patent agent had earlier communicated — in correspondence sent in October 2022 — that the RFE deadline was 27 November 2024, a full year later than the actual statutory date. Relying on this incorrect docketing, Synertec did not file Form 18 by the true deadline. The error only came to light in November 2024, when Synertec followed up with its agent on prosecution status and was informed of the mistake. By then, the Patent Office's online records already showed the application as "deemed to be withdrawn."
Both sides accepted that no formal withdrawal order had actually been passed by the Controller; the status change was purely a statutory consequence of the missed RFE deadline, reflected administratively on the IPO's records.
The Writ Petition
Synertec approached the Delhi High Court under Articles 226 and 227 of the Constitution, seeking to set aside the deemed-withdrawal status and have the application restored to the register. This was not an application for restoration under any specific provision of the Patents Act (the Act does not, in fact, provide a restoration mechanism for RFE defaults) — it was a writ petition invoking the Court's supervisory jurisdiction over the Patent Office's action.
Along with the main petition, the Petitioner also moved two procedural applications, both of which were disposed of by the Court at the outset:
- CM 220/2025 — seeking exemption from filing vernacular translations of supporting documents, allowed subject to translated copies being filed within four weeks.
- CM 219/2025 — seeking exemption from filing apostilled copies of the Petitioner's affidavits (an Australian entity), allowed subject to the requisite apostilled affidavits being filed within four weeks.
Synertec's Case
The Petitioner's central submission was that it had, at all times, acted with diligence in prosecuting the invention: it had timely filed the underlying PCT application, entered national phase, pursued corresponding applications abroad, and had in fact already secured a US patent for the same invention. The sole reason for the missed RFE deadline was the agent's admitted miscalculation — an error attributable to the agent, not to any lapse of intent on the part of the applicant.
To support this position, Synertec placed reliance on two precedents of coordinate Benches of the Delhi High Court:
- European Union (represented by the European Commission) v. Union of India, 2022 SCC OnLine Del 1793
- Bry-Air (Asia) Pvt. Ltd. v. Union of India, 2024 SCC OnLine Del 6956
Both decisions had granted relief in comparable circumstances — deemed abandonment traceable to patent agent negligence rather than any deliberate intention to give up the application — and Synertec urged parity of treatment.
The Union of India's Position
The Respondents (the Union of India and the Patent Office) resisted the petition on the footing that Section 11B(4) operates automatically: once the RFE is not filed within the prescribed period, the application stands withdrawn as a matter of statute, with no discretion vested in the Controller to treat it otherwise. It was submitted that the Patent Office's records accurately reflected the statutory position, that no fault could be attributed to the Office itself, and that even if the Petitioner sought equitable relief, the Controller had no independent power under the Act to revive an application once the deeming fiction under Section 11B(4) had taken effect.
The Court's Reasoning
On 4 September 2025, notice was issued on the writ petition, with the Respondents given time to file a reply and the matter listed for further hearing on 3 November 2025. On the merits — as reflected in the Court's eventual disposal of the petition — the Delhi High Court accepted Synertec's position and distinguished between defaults that reveal an applicant's intention to abandon a patent and defaults that are purely a product of professional error on the part of an agent, over which the applicant otherwise diligently pursuing the invention has no real control.
The Court found the following factors persuasive:
- Consistent diligence in prosecution. Synertec had pursued the PCT and foreign national phase filings, and had already obtained a granted US patent for the same invention — conduct inconsistent with any intention to abandon the Indian application.
- A traceable, singular agent error. The record contained a specific, dated communication from the agent misstating the deadline, allowing the Court to pinpoint the cause of the default rather than infer it.
- No prejudice to third parties or to the integrity of the register. Restoring the application did not disturb any intervening rights, and merely allowed prosecution to continue from where it ought to have stood but for the agent's error.
- Consistency with recent precedent. The facts closely tracked the pattern already recognised in European Union v. Union of India and Bry-Air, where the Court had drawn the same distinction between agent default and applicant intent.
Decision
The Court set aside the "deemed to be withdrawn" status recorded against Patent Application No. 202217030233 and directed the Indian Patent Office to restore the application to its original, pending status. Synertec was permitted to file Form 18 within two weeks of the order, allowing prosecution of the application to resume.
Practical Implications for Applicants and Their Agents
- RFE and national-phase-entry deadlines remain unforgiving in principle — Section 11B(4) operates without any discretion built into the statute itself. Relief in cases like this comes only from the High Court's writ jurisdiction, not from any built-in restoration mechanism in the Patents Act.
- A clear, documented agent error is central to obtaining relief. Synertec succeeded because there was a specific, dated communication that pinpointed the source of the default. Applicants relying on this line of authority should expect the Court to scrutinise the prosecution record closely for evidence distinguishing agent fault from applicant inaction.
- Continued global prosecution activity carries real evidentiary weight. Ongoing PCT, foreign filing, and grant activity for the same invention is treated by the Court as objective proof that the applicant had no intention to give up the Indian application — a fact pattern worth documenting contemporaneously rather than reconstructing after the event.
- This relief is not unlimited. Later decisions applying this line of authority (including in the national-phase-entry context) have drawn a firm line between defaults on extendable procedural steps — such as responding to examination reports — and defaults on deadlines the statute or rules expressly make non-extendable by a deeming provision, such as PCT national phase entry under Rule 22. Applicants and agents should not assume that every missed deadline is curable by analogy to this decision; the availability of writ relief appears to track how rigidly the underlying timeline is drafted.
- Practice point for agents and applicants alike: deadline calculations for RFE and national phase entry should be independently verified and calendared by more than one person or system, given how much litigation this narrow category of error continues to generate.
