PCT Cost for Nepali Inventors: What the International Patent Route Actually Costs
PCT cost for Nepali inventors explained — the international phase fees, the national phase bills, and when the PCT beats direct filing from Nepal on money and time.
The Patent Cooperation Treaty is how one patent application asks for protection across more than 150 countries — and Nepali inventors, whose country is a PCT member, can use it. The question that decides whether they should is usually money: the PCT defers costs and organises them; it does not reduce them.
Understanding PCT cost means separating two phases with two different fee worlds — WIPO's international phase and each country's national phase — and knowing the point at which the deferral stops being worth its price.
In short
PCT cost for Nepali inventors divides into an international phase — transmittal and international filing fees set in WIPO's Swiss-franc schedule, plus a search fee that depends on the chosen search authority — and a national phase, where each designated country charges its own fees through local agents, with entry commonly due around 30 months from the priority date. In Nepal's national phase, the DOI's patent fees apply per the Schedule 3 practice (NPR 1,000 to file, NPR 7,000 to register, then annual maintenance). The PCT earns its cost when several countries are in play and the invention needs market testing; for one or two targets, direct Paris Convention filings within 12 months are cheaper.
PCT cost for Nepal applicants: what it buys
A PCT application starts as a single international filing that designates many countries, produces a prior-art search and a written opinion, and keeps the application pending internationally while the inventor decides where to proceed. Nepal's membership means a Nepali applicant can file through the PCT route as the applicant's receiving-office arrangements allow — the same door foreign inventors use to reach Nepal.
What it does not buy is a patent: no international patent exists. The PCT is a timed, standardised queue — at national phase, each designated country examines and charges under its own law. Every fee the direct route would pay is still payable; the PCT's contribution is time, uniformity and information.
International phase: the first cost block
The international phase has three cost components. A transmittal fee, charged by the receiving Office that takes the application. The international filing fee, set in Swiss francs under WIPO's fee schedule and scaled by the number of sheets and designations. And the search fee, which depends on which International Searching Authority is chosen — authorities differ in price and report turnaround, and the choice is a genuine cost decision.
These figures are currency-denominated and revised periodically, so a Nepali applicant plans them as a quoted package: the agent or receiving office prices the exact combination at the time of filing. Add preparation — specification, claims, drawings — and any translation, and the international phase is a five-figure dollar-scale decision for a quality filing.
| Phase | Cost item | Who sets it |
|---|---|---|
| International | Transmittal fee | The receiving Office |
| International | International filing fee | WIPO schedule, in Swiss francs |
| International | Search fee | Chosen International Searching Authority |
| National | Each country's fees + agent | Each designated office, in local currency |
| Nepal national phase | NPR 1,000 filing, NPR 7,000 registration, annual maintenance (current practice) | DOI, per Schedule 3 practice |
National phase: where the real bill arrives
At national phase — commonly around 30 months from the priority date, with each office publishing its own exact deadline — the application splits into as many national filings as were designated. Each brings its own official fees, translation requirements and local agent costs: entering five countries is five parallel bills, recurring through each country's maintenance calendar.
For Nepal's own national phase, the DOI fees follow the familiar Schedule 3 practice: NPR 1,000 at filing, NPR 7,000 at registration, then annual maintenance inside each 7-year term (NPR 5,000/year in the first renewal term, NPR 7,500/year in the second, in current practice). Foreign applicants route through a local agent under a notarised POA, which is the recurring line foreign PCT entrants should budget alongside the official fees.
PCT or direct filing: the decision rule
The PCT defers most national costs to the 30-month mark, which is its whole financial argument: the inventor buys roughly a year and a half of additional time to find licensees, test the market, and drop countries that are not worth entering — each dropped designation is a bill never paid. The information layer helps the same decision: the international search report reveals the prior art before national money is committed.
The direct Paris Convention route — filing in each target country within 12 months of the first filing — is cheaper for short lists: two or three countries with known value are usually better filed directly, skipping the international-phase fees entirely. The PCT wins when the country list is long, the commercial picture is unresolved, or investors expect an international-stage application. Neither route changes the first rule: the home filing, or the PCT filing itself, starts the priority clock — and the priority date is what every later decision inherits.
Fix the priority date
The first filing — home or PCT — starts every clock; compute the windows before choosing the route.
Price both routes
Country list × national fees + agent costs, versus PCT international phase plus the same national bills 30 months later.
Timing the decision: the two clocks
Both routes run off the same first clock: the priority year. A first filing — at the DOI or anywhere in a Paris Convention country — gives 12 months to file abroad with the earlier date. The direct route uses that year to file in each target country; the PCT route files one international application within the same year, and the national-phase entries then fall due around 30 months from the priority date, per each office's own deadline.
The decision point inside those 18 extra months is commercial, and it is real: search results in hand, market response known, investors met. Inventors who know at month three that only two countries matter file directly and save the international-phase fees; inventors still deciding at month ten are exactly who the PCT was built for.
