Patents are territorial rights, meaning that a patent filed in one country does not necessarily apply in another. The US is a member of the Patent Cooperation Treaty (PCT), which allows US applicants to concurrently seek patent protection in up to 148 countries, including Australia. However, there are differences between the patent laws of the US and Australia, and it is generally recommended to obtain US patent rights before seeking patent protection in Australia. This is because the work carried out by examiners in the US Patent and Trademark Office (USPTO) is highly regarded internationally, and examiners in the Australian Patent Office often use the outcome of US examinations to expedite their own work.

What You'll Learn

US patent rights are internationally highly-regarded
The work carried out by examiners in the US Patent and Trademark Office (USPTO) is highly regarded internationally. This is because the USPTO is a member of the Patent Cooperation Treaty (PCT), which streamlines the process for US inventors and businesses to file for patents in multiple countries. By filing one patent application with the USPTO, US applicants can concurrently seek protection in up to 148 countries.
The PCT facilitates the filing of applications for patents on the same invention in member countries by providing centralized filing procedures and a standardized application format. The timely filing of an international application affords applicants an international filing date in each country which is designated in the international application. This provides a search of the invention and a later time period within which the national applications for patent must be filed.
The PCT route is also advantageous if you are not yet certain about the countries or regions in which you wish to pursue patent protection. As with an Australian complete application, an international application is published approximately 18 months from the initial Australian application. Other advantages of filing an international application include an international search, which is conducted automatically, and the opportunity to amend the application to take account of any relevant prior art that is found by the search.
In addition, the outcome of US examinations is often used by examiners in the Australian Patent Office to expedite their own work. This can be ensured by taking advantage of a Patent Prosecution Highway (PPH) program to accelerate the examination of an Australian application that includes one or more claims corresponding with your granted US claims.

Australian Patent Office examiners use US examination outcomes
The work of examiners in the US Patent and Trademark Office (USPTO) is highly regarded internationally. The outcomes of US patent examinations are used by Australian Patent Office examiners to expedite their own work. This is achieved through the Patent Prosecution Highway (PPH) program, which allows for the accelerated examination of an Australian application with one or more claims corresponding to granted US claims.
The PPH program also works in reverse, allowing applicants for a US patent to gain early examination of their US application based on a clear examination report or the allowance of an Australian patent application. The Australian Patent Office has a more general program of expedited examination, which is granted at the discretion of the Patent Office.
Australian Patent Examiners have adopted the practice of reviewing the online file histories of corresponding US applications during examination. If objections have been raised by the US Patent Office and the pending Australian claims are similar, the Australian Patent Office will typically raise a corresponding objection. This can be avoided by bringing the claims into line with the previously accepted claims.
The US is a member of the Patent Cooperation Treaty (PCT), which streamlines the process for US inventors and businesses to file for patents in multiple countries. By filing one patent application with the USPTO, applicants can concurrently seek protection in up to 148 countries. However, it is important to note that the laws of many countries differ from US patent law. For example, in most foreign countries, the publication of an invention before the application date will bar the right to a patent, and maintenance fees are typically required.

Foreign patent applications can be cost-effective
Firstly, it is important to note that there is no such thing as an "international patent application" or "global patent". Each country has its own patent system, with different requirements and fees. However, there are ways to streamline the process and make it more cost-effective.
One way to reduce costs is to take advantage of international agreements such as the Patent Cooperation Treaty (PCT) or the European Patent Convention (EPC). The PCT allows applicants to file one application with the US Patent and Trademark Office (USPTO) and concurrently seek protection in up to 148 countries. This can save applicants the cost of filing separate applications in each country. Additionally, the PCT provides a standardized application format and centralized filing procedures, making it easier and more cost-effective to apply for patents in multiple countries.
The EPC is similar to the PCT in that it allows applicants to file one application and select specific countries to register the patent within a certain timeframe. This can be more cost-effective than filing separate applications in each European country.
Another way to reduce costs is to be strategic about the countries you select for patent protection. For example, if you are only interested in European countries, you may want to consider filing regionally under the EPC. This can help you defer translation costs, which can be substantial. Additionally, some countries, like China, have inexpensive utility model patents that can be a more cost-effective option.
It is also important to consider the size of your patent application, including any drawings or claims. Many countries charge excess page and claim fees for applications that exceed the limit, so keeping your application concise can help reduce costs.
Finally, it is worth noting that the cost of obtaining a foreign patent can depend on the timing of your application. For example, under the PCT, applicants can defer national phase filing and associated costs for up to 30 months from the original US filing date. This allows applicants to buy themselves time to decide which countries to file in and can help spread out the costs of obtaining patents.
In conclusion, while obtaining foreign patents can be expensive, there are ways to make the process more cost-effective. By taking advantage of international agreements, being strategic about country selection, keeping applications concise, and timing your applications carefully, you can reduce the costs of obtaining foreign patents.

US patent law differs from Australian patent law
Secondly, the US and Australia have different requirements for obtaining foreign filing licenses. US residents may be legally required to first file in the US or obtain a foreign filing license before filing in another country. On the other hand, Australia, as a member of the Paris Convention, allows foreign patent applications to be deferred for up to 12 months from the initial Australian application date while retaining the priority date.
Thirdly, the US and Australia have different approaches to provisional applications. While both countries offer the option of provisional applications, they serve different purposes. In the US, a provisional application is often used as a strategy to obtain a foreign filing license, while in Australia and other countries, a provisional application provides full support for the protection ultimately granted.
Additionally, the US Patent and Trademark Office (USPTO) and the Australian Patent Office differ in their examination processes. The work of USPTO examiners is highly regarded internationally, and their outcomes are often used by Australian examiners to expedite their own work. This can be further facilitated through the Patent Prosecution Highway (PPH) program, allowing for accelerated examination of Australian applications with corresponding US claims.
Lastly, the US and Australia may have different requirements for maintaining patents. While it varies by country, many countries require maintenance fees and mandate that the patented invention be manufactured in that country after a certain period, typically three years. Failure to comply with these requirements may result in the patent being void or subject to compulsory licensing.

US patent applications can be filed in multiple countries
If you are a US resident, you may be legally required to either file first in the US or obtain a formal approval (a 'foreign filing licence') to file initially in another country. The easiest way to obtain this licence is by filing a US patent application covering the invention. The US and Australia both offer the option of filing either a provisional application or a 'full' application (usually called a ''complete' application in Australia, or a 'utility' or 'nonprovisional' application in the US). A provisional application is never examined and cannot result in a granted patent. It is important to note that the laws of many countries differ from US patent law. For example, in most foreign countries, publication of the invention before the date of the application will bar the right to a patent, and maintenance fees are required.
If you have filed a patent application in the US, you have 12 months to file your application in Australia. If you want to apply for a patent in several countries, or are unsure whether you might want to patent in more countries at a later date, an international application may be appropriate. This can be done through the PCT, which allows you to apply in all member states at once. As a rule of thumb, for each country, you should budget downstream examination costs to be at least as much as the initial filing cost for that country. Additionally, renewal fees are typically due annually and may begin shortly after filing or after a patent is granted, depending on the country.
The PCT route is also advantageous if you are uncertain about which countries or regions you ultimately wish to pursue patent protection. An international application includes an international search, which is conducted automatically, and provides the opportunity to amend the application to take account of any relevant prior art that is found. For example, if relevant prior art comes to light, the international application can be amended instead of having to amend a number of national applications. Amendments can be made within two months of the international search report or during an optional international preliminary examination.
