Patents

Protect the functionality of your invention

What is a patent?

A patent provides a legally enforceable right to prevent others from using, selling, importing or making an invention for a period of 20 years.

The invention can be a device, substance, method or process.

What are the requirements for the grant of a patent?

A patent can be for any invention that satisfies at least the following requirements:

Novelty

The invention must be ‘novel’ or new. In other words, the invention must not have been publicly disclosed or used anywhere in the world. 

Inventive Step

The invention must involve an ‘inventive step’. This means that the invention must not be obvious to a person who is experienced in the same technical field as the invention. An ‘obvious’ invention is one that would be arrived at ‘as a matter of course’ in light of the general body of knowledge known or used by those in the field of the invention.

Utility

The invention must be useful or have utility. In other words, the invention must achieve the purpose intended by the applicant/patentee.

Obtaining patent protection in Australia and overseas

Provisional patent application

The first step towards obtaining patent protection generally involves filing a provisional patent application. The provisional patent application will establish a ‘priority date’ for your invention, which is the date used for assessing the novelty and inventive/innovative step of your invention.

The provisional patent application lasts for 12 months, which is a useful period for deciding on whether to continue with the patenting process in Australia and elsewhere.

*Please note: a provisional patent application on its own does not provide any patent protection.

Options for pursuing patent protection in Australia and overseas

Within 12 months of filing the provisional patent application, you must decide how you would like to progress the patenting process. Applicants have two main pathways:

  • Direct filing
    This pathway involves filing a patent application directly in each of the countries or regions of interest (including Australia).

  • The PCT application
    This pathway involves filing an International (PCT) patent application. The advantage of the PCT pathway is that it provides you with at least an additional 18 months to decide on which countries or regions (including Australia) you wish to pursue patent protection. After filing the PCT application, a prior art (background) search will be performed and a preliminary non-binding opinion on the patentability of the invention will be provided. The PCT application must then be “nationalised” by filing a corresponding patent application in each of the countries or regions of interest (including Australia).

    For more information regarding the PCT pathway, please visit the WIPO website and view the PCT Applicant’s Guide.

As noted above, regardless of which pathway (Direct or PCT) is taken, a separate patent application will need to be filed in each country or region of interest. Each patent application will then be examined according to the patent laws and regulations of the particular Patent Office in each country or region.

Australian patent application process

After filing a standard patent application in Australia, or entering the National Phase of a PCT application in Australia, examination must be requested within 5 years from the filing date. However, in practice, the Australian Patent Office will set an earlier deadline by issuing a Direction to Request Examination. Once the Direction issues, examination must be requested within 2 months. From our experience, the Direction will typically issue about 55 months from the filing date due to delays at the Australian Patent Office.

After requesting examination, it will typically be 12-18 months before a first examination report issues. The acceptance (i.e., allowance) deadline will be 12 months from the date of the first examination report.

Following successful examination, the application will proceed to acceptance and third parties are provided with an opportunity to oppose the grant of a patent within 3 months of the advertisement of acceptance. If there is no opposition, a patent will issue shortly thereafter.

The flow chart below outlines the stages in the standard patent application process in Australia.
