Hong Kong Patent Application Fees 2026: Costs & PAG Grant
AI Quick Answer
Introduction
"How much will it actually cost to patent my invention?" It is the first question almost every inventor, startup founder and SME owner in Hong Kong asks — and the one most people get wrong in both directions. Some assume patenting is only for large corporations and abandon perfectly protectable inventions. Others rush to file on their own, then discover a pile of hidden costs: examination requests, amendments, renewals, and the price of fixing a badly drafted specification — which often costs more than drafting it properly the first time.
The real problem is that "patent fees" is not one number. It is a stack of separate costs that hit at different stages, and the single biggest lever — the Hong Kong government's Patent Application Grant — is the one most applicants have never heard of. This guide breaks down every layer of Hong Kong patent application fees for 2026, so you can budget with confidence before you file a single document.
How Much Does a Hong Kong Patent Application Cost? The Three-Layer Breakdown
Hong Kong patent application fees fall into three distinct layers:
Layer 1 — Official fees (IPD): What you pay the Intellectual Property Department to file, examine and grant your patent. These are fixed and relatively small.
Layer 2 — Professional fees: What you pay a patent attorney or agent to draft the specification, claims and drawings, respond to examination reports, and manage the process. This is usually the largest layer.
Layer 3 — Lifecycle costs: Annual renewal fees after grant, plus optional costs such as overseas filings, translations and enforcement.
A realistic total for a straightforward short-term patent drafted by a professional is roughly HK$10,000 to HK$20,000 all-in for the first few years. A standard patent covering a more complex invention — including substantive examination and a professionally drafted specification — commonly runs from HK$20,000 to HK$60,000 or more over its first five years. The exact figure depends almost entirely on the complexity of your invention and the quality of the drafting, not on the government fees.
IPD Official Filing Fees: Standard vs Short-Term Patent
The Intellectual Property Department's official fees are the most transparent part of the budget. Approximate figures:
Short-term patent: filing fee from about HK$755. A short-term patent is granted without substantive examination, which is why the official cost is low.
Standard patent (original grant): filing fee from about HK$380, plus a substantive examination request fee of about HK$3,980, plus grant-related fees on the way through.
Three points matter here. First, these are per-application figures — adding claims, requests for extension of time, or amendments all carry surcharges. Second, official fees change from time to time, so always confirm the current schedule on the IPD website before budgeting. Third, and most importantly: the official fees are the smallest part of your total spend. The core cost of a patent is in the drafting quality, not the submission.
Patent Attorney and Agent Fees: What Actually Drives the Cost
Professional fees vary widely because patent drafting is skilled technical writing. What drives the price:
Technical complexity. A mechanical device with one clever mechanism costs far less to draft than a biotech or software-implemented invention.
Quality of the specification. The claims define the boundary of your protection. A cheap, vague draft may get granted but will be easy for competitors to design around — which is the most expensive outcome of all.
Examination responses. For standard patents, responding to office actions takes professional time.
Whether prior-art searching is done first. A professional search before filing (a few thousand dollars) routinely saves applicants from spending tens of thousands on an application that was never patentable.
A good test when choosing a provider: if they never mention a pre-filing patent search, treat that as a warning sign, not a discount. Filing without searching is how people pay full fees for patents that get refused or invalidated.
The Patent Application Grant (PAG): Up to HK$250,000 Off Your Costs
This is the layer most applicants miss. The Patent Application Grant (PAG) is a Hong Kong government funding scheme, administered by the Hong Kong Productivity Council on behalf of the Innovation and Technology Commission, that helps local companies and individual inventors pay for patent applications.
Maximum funding: HK$250,000, or 90% of the total direct costs of the patent application, whichever is lower.
Coverage: applications in Hong Kong, Mainland China, the United States, Europe, Japan, Germany and the United Kingdom.
Who qualifies: locally incorporated companies and individual Hong Kong residents who own the invention — including SMEs and startups.
In practice, PAG can cover most of the professional drafting and official fees for your first patent filing. For a cost-sensitive small business, checking PAG eligibility before you file is the single highest-return ten minutes you can spend on your patent budget.
Standard vs Short-Term Patent: Which Should You Choose?
The cheapest option is not always the cheapest decision:
Short-term patent: lower official fees, no substantive examination, maximum term of eight years. Best for innovations with a short commercial life.
Standard patent: higher official fees and full substantive examination, but a 20-year term and a stronger presumption of validity — meaning it is harder for competitors to challenge.
If your invention anchors a long-term product line or you plan to license it, the standard patent's stronger protection is usually worth the extra cost. If you are testing a fast-moving consumer product, a short-term patent may be the sensible first step.
Five Cost Traps That Burn Inventors' Money
Skipping the prior-art search. Paying full drafting fees for something that was already patented.
Choosing the cheapest drafter. A vague specification limits your claims and invites design-arounds.
Ignoring renewal fees. Annual renewal fees rise as the patent ages; forgetting them lapses your patent, and a lapsed patent cannot be restored casually.
Filing in the wrong jurisdictions. Hong Kong registration does not protect you in Mainland China or the US. Plan the filing family early, because foreign claiming deadlines are unforgiving.
Missing the PAG window. The grant supports applications — applying for funding after you have already filed wastes the benefit.
FAQs
How much does it cost to file a patent in Hong Kong?
Official fees start from about HK$755 for a short-term patent, and from about HK$380 plus about HK$3,980 for substantive examination for a standard patent. Professional drafting typically adds HK$10,000 to HK$50,000 depending on complexity. Renewal fees apply annually after grant.
What is the Patent Application Grant (PAG) and who qualifies?
PAG is a Hong Kong government scheme funding up to HK$250,000 or 90% of total direct application costs, whichever is lower. Locally incorporated companies and Hong Kong resident inventors qualify, covering filings in Hong Kong, Mainland China, the US, Europe, Japan, Germany and the UK.
Do I need a patent attorney to file in Hong Kong?
No — you can file directly with the Intellectual Property Department yourself. But the quality of the specification and claims determines how enforceable your patent is, so professional drafting is strongly recommended for anything commercially important.
How long does a Hong Kong patent last, and what are renewal fees?
A standard patent lasts up to 20 years; a short-term patent up to 8 years. Both require annual renewal fees that increase with the patent's age — forgetting a renewal lapses the patent.
Standard or short-term patent — which is cheaper?
A short-term patent is cheaper up front because there is no substantive examination. But it offers a shorter term and weaker legal presumption, so for long-lived, high-value inventions the standard patent is usually the better investment.
