What does examination involve?

This is determined by what kind of patent you choose-innovation or standard. The progress of your application will also depend on you (or your attorney) paying the Patent Office fees required at various stages.

All examinations and sealing of patents are undertaken at the Patent Office of IP Australia in Canberra to ensure your application meets the requirements of the Patents Act.

Innovation Patents

  • Innovation patents are not automatically examined. To fully enforce your rights to your innovation within the marketplace, your patent must be certified following an examination.To request an examination, you must complete a Request for Examination form, and pay the required fee. For more information on the examination process of an innovation patent, please click here.

Standard Patents

You may request early examination of your standard patent application, although generally between 1 and 2 years after filing we will direct you to request an examination if you have not already done so.

Once we have directed you to request examination, you have 6 months to do so. If you don't, your application will lapse.

It may be to your advantage NOT to seek early examination and grant of a patent.

Delaying examination allows you more time to assess your progress in commercialising the invention and the value of continuing the patenting process.

When granted, your patent rights can be enforced back to the publication date of your complete application so there is usually no benefit in finalising your patent quickly unless you need to take immediate legal action against an infringer or require a granted patent for licensing or financing negotiations.

If you have applied for a patent for the same invention overseas, you are required to give us the result of any official search carried out.

How long will it take?

You can normally expect to receive a reply to your request for examination within about 14 months depending on our workload. More detailed response times and other Service level Commitments can be found in our Customer Service Charter.

This will either be an adverse report (a report giving reasons why your application does not meet the requirements of the Patents Act in its present form) or a notice that your application has been accepted.

What if there are problems with my application?

Few applications are approved in their initial form.

The patent examiner will inform you of any deficiencies and give you the opportunity, within certain time limits, to make changes to your application.

Usually problems occur because you did not fully describe your invention when you filed your application, or because your claims are too broad and cover something that is already known.

If you receive an adverse report, additional help is available in our information sheet Responding to a Patent Examination Report which we usually send to you at the same time.

When we are satisfied that you have corrected the deficiencies, your standard application will be accepted, or your innovation patent will be certified. However if the problems cannot be overcome, your standard application will be refused or your innovation patent will cease, and you will not obtain legal protection for your invention. For a standard patent, there is a period in which other people can oppose your application. For an innovation patent it will be certified at this stage, and it can be opposed at any time from then on.

Publication

Publication of your unexamined standard application (level AU-A) occurs about 18 months after your application's earliest priority date in the Australian Official Journal of Patents (AOJP). Published patent specifications are made available to the public and are sent to certain libraries and overseas patent offices.

Innovation patents are published at grant which generally occurs shortly after filing. This means that the contents of your patent specification are no longer confidential.

It also means that you can take action if someone uses your invention without your permission. Once we have granted a standard patent or certified an innovation patent, you may be entitled to take legal action for any infringements that occurred from the date we published your application.

Please note: Publication of your patent DOES NOT guarantee grant of a patent.

If your standard application is accepted, the patent is republished as an AU-B level publication. A comparatively small number of standard applications are first published when accepted.

If your accepted standard application is subsequently amended it is republished again as an AU-C level publication.

Acceptance, opposition and grant

After the publication of acceptance of your standard patent application, others then have 3 months to start proceedings to show that your patent, if granted, would be invalid. However, less than 2% of accepted applications are opposed.

If your standard patent application is not opposed, we will seal it and send the patent certificate to you after the end of the opposition period.

How long will my patent be valid?

The maximum term for a standard patent is 20 years. The maximum term for an innovation patent is 8 years. This is counted from the day you filed your complete application.

There is, however, special provision for an extension of term for pharmaceutical patents.

It is your responsibility to remember to pay the annual maintenance fees.

We cannot help you enforce your patent rights. You should consult an IP professional if you are concerned about someone infringing your IP rights.
