When to engage an industrial property representative
·
Foreign applicants must go through a representative; Vietnamese applicants need not. So when is one worth hiring, and how do you pick someone who will not wreck your file.
An industrial property representative is a licensed practitioner who handles procedures before the IP Office on the applicant's behalf. This is a distinct profession — different from a general lawyer or a fly-by-night "filing service" — and that distinction decides who deserves your money.
When it is mandatory
A foreign applicant not resident in Vietnam must act through an industrial property representative. Vietnamese individuals and organisations are not required to.
When it is worth paying for
"Not required" does not mean "not worth it". Three situations where the fee almost always pays for itself:
- Patent applications. The quality of the claims determines the value of the patent. Too narrow and competitors design around it; too broad and it is refused — this is a skill, not form-filling.
- Trademark applications with conflict risk. When a search shows similar marks already exist, you need someone who can judge the refusal risk and handle oppositions.
- International filings through the PCT, Madrid or Hague — many deadlines and procedures across countries, where one mistake loses your place.
When you can reasonably self-file
Two situations are safe to do yourself: copyright registration for your own work (simple, no substantive examination), and a simple single-class trademark with a sign you have searched thoroughly and found clear.
How to choose a representative
Four things to check before authorising anyone:
- A current practising certificate — the register of practitioners is public.
- The right technical field. A mechanical, chemical or biotech patent needs someone who understands that field; a trademark specialist is a poor fit for a patent.
- Experience with your specific filing type, especially international ones.
- A clear handover and filing calendar — deadlines are the one thing you cannot recover once missed.
Common mistakes
Handing the file to an unlicensed "filing service". They may take your money and file wrongly or incompletely, with no professional liability to fall back on as there is with a licensed practitioner.
Authorising and then disengaging. An authorisation does not unconditionally transfer responsibility for deadlines to the representative — you must still track the key milestones (priority deadlines, maintenance fee dates) to avoid being caught out. See renewing and maintaining your titles.
