Patent Publication in Nepal: When the Gazette Publishes and What It Changes

Patent publication in Nepal: where it sits in the journey

The sequence under the PDTA: the Schedule 1(a) application is filed (NPR 1,000 in current practice), examined — formality checks, then the technical committee's substantive review with amendments and re-examination — and, once accepted, published in the Nepal Gazette. Registration follows the objection window: the NPR 7,000 registration fee is paid and the patent enters its first 7-year term.

The timing consequence is worth stating plainly: by the time the invention publishes, it has already survived examination. Publication is the last public checkpoint before grant — the moment for prior-publication objections is 35 days, not a lifetime.

The 35-day objection window

Particulars of the published patent can be inspected, and objections lie within 35 days of publication. The proceeding is fought on the file: an opposer states grounds and evidence, and the classic ground is prior publication or prior knowledge of the invention — someone, somewhere, had it before the applicant filed.

For patentees, the window is a vulnerability to monitor rather than fear: competitors and institutions watch publications in their fields, and an opposed application must answer. For the public, it is the accountability mechanism that keeps a flawed grant from hardening into an enforceable right.

The exceptions: secret patents and national interest

Section 7A carries exceptions for secret patents and matters running against the national interest — the statutory recognition that some inventions (defence-relevant technology, sensitive processes) cannot simply be published. These are narrow, administered categories, not a commercial opt-out: an applicant does not choose secrecy to protect a competitive advantage. For ordinary commercial inventions, plan on publication as a certainty of the route.

The planning consequence for genuinely sensitive processes is the trade-secret route instead: keep the process confidential by contract and controls rather than trading publication for a 7-year term — the classic recipes-versus-patents decision.

Why publication is permanent: the prior-art effect

The published specification does not disappear if the patent later lapses, is cancelled, or is never renewed — and that permanence reshapes the whole lifecycle. A published specification is prior art against any refiling of the same invention: the patentee who misses a renewal deadline (35-day window, 6-month grace, then automatic cancellation) cannot simply refile, because their own publication defeats the novelty a new application would need.

This is the asymmetry that makes patent renewal discipline absolute in Nepal. A lapsed trademark can sometimes be re-registered if nobody has moved; a lapsed patent is unrecoverable in substance — the invention is public, and the exclusivity is gone.

What publication does for the patentee

Publication is not only exposure — it performs work for the right. The Gazette entry is public notice: from publication, the world is on notice that the application exists, which supports the patentee's position in disputes over independent later development. The registration that follows gives the enforceable right — but the publication date is the anchor documents cite in challenges, negotiations and licensing diligence.

It also functions as the patent system's transparency layer: examiners, competitors and researchers read the Gazette, and the published specification is how Nepal's small patent record becomes usable knowledge rather than a private archive.

Planning around publication: the pre-filing decision

Because publication follows examination, the decisions that matter happen before filing: run the novelty search (finding the killing publication before the DOI does), decide patent versus secret on the disclosure question, and complete the specification — amendments after filing cannot add new matter, and the published document is the one that counts. After publication, the calendar takes over: renewal within 35 days of each term expiry on Schedule 2(d), with annual maintenance inside each renewal term, through a 21-year maximum.
