Timing and requirements for filing the opposition documents

When an innovation patent is examined and the Commissioner is satisfied that the requirements for certification have been met, a notice to this effect is advertised in the Official Journal of Patents under section 101E(2)(b).  

At any time after certification, a person may oppose an innovation patent under reg 5.6.  To commence the opposition, the person must:

  • pay the fee for filing a notice of opposition (see Schedule 7, item 216); and
  • file all of the following documents with the Commissioner at the same time:
    • a notice of opposition in the approved form (available on the IP Australia website);
    • a statement of grounds and particulars in the approved form (available on the IP Australia website);
    • the evidence in support of the of the opposition; and
    • a copy of each document mentioned in the statement of grounds and particulars, unless:

i. the document is open for public inspection and relates to a patent or patent application and/or

ii. the document has been filed as evidence in support.​​​​​​​

The statement of grounds and particulars

The statement of grounds and particulars must set out the grounds the opponent intends to rely on to establish the opposition, and the facts and circumstances (the particulars) forming the basis for the grounds (reg 5.2 “Definitions”).  

The grounds of opposition under section 101M are limited to one or more of the following:

a. that the patentee is either:

i. not entitled to the patent (section 33(3))

ii. entitled to the patent but only in conjunction with some other person (section 33(4));

b. that the complete specification does not comply with section 40(2), 40(3) or 40(3A);

c. that the invention is not a patentable invention because it does not comply with paragraph 18(1A)(a), (b) or (c);

d. that the invention is not a patentable invention under subsection 18(2) or (3).

For more information on the function and content of the statement of grounds and particulars see 7.4.2 The Statement of Grounds and Particulars.

The approved form of the statement of grounds and particulars (available on the IP Australia website) contains a Schedule in which every document mentioned in the statement must be listed, together with an indication that:

  • the document has been filed with the statement; or
  • the document has been filed with the evidence in support; or
  • the document is open for public inspection (see “Open for public inspection” below) and relates to a patent or patent application.  (Where the document is made open for public inspection on the file of a related Australian patent or patent application, the opponent must identify the relevant patent or patent application.)

Note: The requirement of reg 5.6(1)(c), that documents mentioned in the statement of grounds and particulars must be filed with the opposition documents, does not replace the need for the cited documents to be adduced in evidence.  All documents that the opponent intends to rely on to establish the grounds of opposition must be filed as part of the evidence in support.  

Open for public inspection

A patent document is open for public inspection for the purposes of reg 5.6(1)(c) if, at the time of filing the statement:

  • the document is open for public inspection at the patent office in Australia; or
  • the document relates to a PCT application designating Australia that had been published by World Intellectual Property Organisation (WIPO).

Unless the document is on the file of a related Australian application and thereby open for public inspection at the patent office in Australia, documents that are not open for public inspection include:

  • any overseas patent specification (eg. US, EP, GB specifications);
  • the specification of a patent application filed via the PCT designating Australia, that had not been published by WIPO at the time of filing the statement of grounds and particulars; and
  • citations raised in examination and re-examination reports.

 

Initial processing of the opposition documents

Once the opponent has complied with requirements of reg 5.6(1)-(2), the opposition officer will acknowledge receipt of the documents to the parties, and give the patentee a copy as soon as practicable.  

 

Deficient particulars - further and better particulars

Where the particulars of the opposition are deficient, the patentee may request the Commissioner to issue a direction for further and better particulars.

For more information on directions for further and better particulars see 7.3.1.2 Further and Better Particulars.

 

Amending opposition documents

 

The notice of opposition

Under regs 5.14 and 5.15, an opponent may request an amendment to the notice of opposition to correct a clerical error or obvious mistake, or to change the name of the opponent where the opponent’s right or interest in an opposition is transferred to another person.

For more information, see 7.4.3 Amending Opposition Documents.

The statement of grounds and particulars

Under reg 5.16, an opponent may request the Commissioner in writing to amend its statement of grounds and particulars to:

  • correct an error or omission in the grounds of opposition; or
  • update the grounds of opposition to reflect an amendment to the complete specification to which the statement relates; or
  • to amend the facts and circumstances (the particulars) forming the basis for the grounds.  

However, the Commissioner has no power to amend the statement where an application for dismissal of the opposition is under consideration (reg 5.16(3)(a))

For more information, see 7.4.3 Amending Opposition Documents.

 

 

Dismissal of the opposition

The Commissioner may dismiss the opposition if the prescribed documents are not filed with the statement

If copies of the required documents are not filed with the opposition documents or as part of the evidence in support, the Commissioner may dismiss the opposition under reg 5.18(2).  

Other grounds for dismissal

Other grounds for dismissal of an opposition include that the opposition has no reasonable prospects of success.  For more information see 7.7.2 Dismissal of an opposition.

Requests for dismissal of the opposition

Under reg 5.17 a patentee may, within 1 month of the receipt of the statement of grounds and particulars, request the Commissioner to dismiss an opposition.  

For more information, see 7.7.2 Dismissal of an Opposition.

 

 

Withdrawal of the opposition

Under reg 5.26, an opponent may withdraw an opposition at any time, by filing a notice of withdrawal in the approved form (available of the IP Australia website).  For notices of withdrawal filed before 25 August 2018 there is a requirement that the notice be signed.

For more information, see 7.7.1 Withdrawal of an Opposition.
