You will learn to

Explain the territorial nature of trade marks, patents and industrial designs.
Distinguish regional rights (EU, EPO) from international filing systems (Madrid, PCT, Hague).
Recognise that each country still decides whether to grant protection.

Rights stop at the border

Registered trade marks, patents and industrial designs are territorial: a registration granted by one country has effect only in that country. An Australian registration does not stop anyone in Vietnam, Singapore or Japan, and the reverse is also true. Copyright generally arises without registration in countries that belong to the Berne Convention, but its scope and enforcement still follow each country's law. So the right question is not "are we protected?" but "in which countries are we protected, and for what?". A plan to go abroad starts with a specific list of markets.

Regional rights: one application, several countries

Some regional systems grant a single right for several countries. The EU trade mark and the registered EU design, granted by EUIPO, have effect across all EU member states. Patents work differently: the European Patent Office (EPO) examines and grants a European patent through one procedure, but that patent must then be validated in each country the owner chooses. The owner can also request unitary effect (the Unitary Patent), which covers the participating EU member states in one step — not every EU country; non-participating EU states and EPO states outside the EU still need their own validation.

International systems: simpler paperwork, not a global right

WIPO administers three international filing systems. The Madrid System is for trade marks. The PCT is for patents: a PCT application is an international application, not a patent — after the international phase you must enter the national phase in each country where you want protection, usually around 30 months from the earliest priority date, depending on the country. The Hague System is for industrial designs. In all three, each designated country still examines under its own law and may refuse. Check membership too: Australia, for example, is not a member of the Hague System.

Try a scenario

"Crowdline", a Melbourne event-management software company, holds a registered Australian trade mark. Next year it launches in Germany, France and Japan.

Which approach reflects territoriality correctly?

Nothing — an Australian mark is recognised in developed countries.Consider an EU trade mark for Germany and France, and separate protection for Japan (a national filing or a Madrid designation).File one PCT application to cover all three.

Pass mark: 80% — for this lesson that means every question.

Question 1 of 4A Da Lat start-up has just filed a PCT application for a smart irrigation system and tells investors it "has an international patent".Which description is more accurate?

They hold a patent in every PCT member country.They have a pending international application; protection depends on entering the national phase and being granted in each country.They hold a Vietnamese patent, because the application was filed from Vietnam.

Take away

For each market, write down which right, which route (national, regional or international), and whether that country belongs to the system you plan to use.

Nothing runs or is saved on its own. Each option only opens a tool when you choose it.
