International Patent Protection


Do you need to obtain IP protection overseas? We regularly help our clients obtain intellectual property rights in many overseas countries. Apart from the more common filing jurisdictions of the USA, New Zealand, Europe, Japan and China, we’ve also helped our local clients seek IP protection in less common filing countries such as  Israel, Colombia, Chile Peru, Russia, Malaysia, South Africa, Canada, Korea, Indonesia, Vietnam, India, Mexico, Singapore, Brazil, Nigeria, Philippines., Algeria and Morocco.   We do this by understanding and using a number of  international agreements concerning intellectual property,  such as the Paris Convention, Patent Cooperation Treaty and Madrid Protocol.


We find that many Australian businesses and individual inventors have plans for commercializing their product in overseas countries. We can help you to defer the timing and costs of overseas applications while still preserving your potential intellectual property rights in foreign jurisdictions.

The Paris Convention for the Protection of Industrial Property was established in 1883. Under the terms of the Paris Convention each member country recognizes a reciprocal right of priority for IP  applicants from each of the other Convention countries. What that means is that if you firstly file a patent, trade mark or design registration application in Australia for your invention then, you’ll have up to twelve months for patents, or six months for trade marks and designs, to file an application for the same invention, claiming the priority date of your Australian application, in one or more of the Convention countries.

The Paris Convention makes a number of stipulations as to how the overseas right of priority is to be claimed and the circumstances in which it can be claimed.  For example, one potential minefield in using the Paris Convention is that under Article 4(C) it is a requirement that the basic application, i.e. the application from which priority is claimed must be the first “live” application and that any earlier application must have lapsed or been withdrawn without any rights outstanding.  The way that the Articles of the Paris Convention are implemented in each country can vary and so it’s important that professional advice is provided to ensure that the earlier priority claim isn’t compromised.  We can help you to meet your Paris Convention deadline and to avoid the risk of overlapping applications that could jeopardize your right to validly claim an earlier priority date when filing overseas.


Australia is a signatory to the Patent Cooperation Treaty (PCT), which is administered by the World Intellectual Property Organisation based in Geneva.  The PCT provides for an international patent application (but not for an international patent) which presently covers about 145 countries.

The filing of foreign national applications can be deferred for 2.5 years from the Australian provisional filing date in countries which are party to the Patent Cooperation Treaty (PCT) by lodging an international patent application.

It will still be necessary to file individual national applications, but not until up to 2.5 years (30 months or in some countries later) from the filing date of the original Australian provisional patent application. Thus, the international patent application provides time in which to investigate, or even venture, into foreign markets before having to incur the cost of filing the individual national applications.

A prior art patentability search will be conducted on the international application shortly after filing. It is also possible to have an international preliminary examination conducted while the international application is in place.

Amendments and arguments can be lodged during the examination procedure with a view to obtaining a preliminary examination report indicating patentability.

If you choose to file an international application, and not all the nations of interest to you are contracting parties to the PCT, then it may be necessary also to file some direct national applications under the Paris Convention.

We find that most of our local clients decide to start their overseas filing strategy by filing a PCT application.  An exception to that would be where the client  specifically only wishes to seek patent protection in a small number of countries (e.g. US, Australian and New Zealand) and there is no likelihood of them needing to expand the number of countries in the coming eighteen months.  Unfortunately, it is always possible that after the filing deadline has passed there will be a reason for seeking protection in additional countries. The great advantage of the PCT application is that it keeps options open  in about 145 countries in the critical early stages of the patenting procedure.  From a cost perspective the cost of filing a PCT application is typically about the same as filing directly into USA, China and New Zealand.

When a PCT application is lodged with IP Australia as the receiving office there is a choice of international searching authorities that can be selected.  Typically, where the Australian Patent Office (“IP Australia”) is the designated Receiving Office of the PCT application then IP Australia is also selected as the International Search Authority although other office’s such as the Korean Intellectual Property Office can be chosen instead.  Consequently, about nine weeks after lodging the PCT application the ISA deparatment of IP Australia will perform the international patentability search of the PCT application and issue an international search report and written opinion on patentability.

The international search report and written opinion are helpful because they can be used to assess whether amendments should be made to the claims in the patent specification to distinguish those claims over the documents that have been cited as being relevant to patentability.
