A courteous call from a Patent Office Controller flagged a filing slip we’d made — amendment requests filed under the wrong Rule, attracting a higher fee. In the spirit of “pay it forward,” here’s the fix, so other practitioners don’t repeat it.
The call
A Deputy/Joint Controller at the Delhi Patent Office rang to explain that some amendment requests had been filed in the correct Form but under a different Rule, resulting in a higher official fee. He wanted the agent to know, so it wouldn’t recur — stressing the value of communication between the Office and practitioners in improving the Office’s functioning and helping new agents learn the nuances. Helpfully, he said fresh requests weren’t needed — he’d allow the requests — with advice to be careful in future.
This wasn’t the first such courtesy. On another occasion, a Controller called to confirm our examination-report response and amendments were acceptable for grant, needing only a delay-condonation request — then followed up the next day to ensure we filed it, and the patent granted within minutes. With the Office’s digitalisation, e-filing worked smoothly even through the national lockdown.
The nuance: Rule 90 vs Rule 94
Here’s the substance, laid out to help others:
- Rule 90(1) and 90(2) — transfer of rights of a granted patent — are carried out in Form 16.
- Rule 94(1) — amendment to the patentee’s name, address, nationality and address for service in India.
- Rule 94(3) — amendment for an additional address for service in India.
Critically: the Rules specify Form 16 for Rule 90(1)/(2), but specify no particular form for Rule 94(1)/(3). Looking at Form 30 with the “with a fee” option, requests under Rule 94(1) and 94(3) fall under Schedule 1, Entry 26 and 27.
So — use Form 16 for Rule 90 transfers, and Form 30 (with fee, entries 26/27) for Rule 94 name/address amendments. Filing a Rule 94 request under a Rule 90 heading (or vice versa) is exactly the kind of mismatch that overcharges you and can get requests refused.
The takeaways
- Rule 90 (transfer of granted patent) → Form 16.
- Rule 94(1)/(3) (name/address amendments) → Form 30 (with fee, Schedule 1 entries 26/27).
- Wrong-rule filings overcharge and risk refusal — match the form to the rule.
- Communication helps everyone — the Office’s courtesy, and sharing the fix, improves practice.
