General Information

For oppositions commenced before 15 April 2013, a party seeking to rely on evidence in an opposition under section 104(4) must file it with the Commissioner within the evidentiary periods prescribed by reg 5.8 as in force immediately before 15 April 2013, subject to reg 23.36(2).

For oppositions commenced on or after 15 April 2013, where a party wishes to file evidence the evidentiary periods will be set by direction under reg 5.12.

The process and procedure for filing evidence is summarised below.

Physical evidence

Physical evidence should not be filed.  Rather, the documentary evidence should include a description of the physical item including, as appropriate, a photograph or video recording as well as an indication of the place at which the item may be inspected.

The Commissioner may subsequently order inspection of the item or direct that it be filed, as the Commissioner determines to be appropriate.

For information on evidence in general see 7.5 Evidence.

Filing evidence in oppositions commenced before 15 April 2013

Note: Where an opposition commenced before 15 April 2013, and evidence is due to be served on a party on or after 15 April 2013, and the evidence has not been served before 15 April 2013, the evidence must be filed with the Commissioner on or before the due date for service and the opposition officer will give a copy of the evidence to the other party.  

Pursuant to reg 23.36(2), if the party is given the evidence after the date it is filed, the Commissioner will extend the subsequent evidentiary period by the number of days equal to the number of days between the filing date and the date the evidence was given to the other party.

In oppositions commenced prior to 15 April 2013, the evidentiary stages are governed by reg 5.8, as in force immediately before 15 April 2013, subject to reg 23.36(2) where appropriate.  

Note: Physical evidence should not be filed unless requested or directed by the Commissioner.

The evidentiary periods are as follows.  

Evidence in support

After 15 April 2013, the opponent must file any evidence in support of the opposition within 3 months after the day the opponent files (or before 15 April 2013 serves) the statement of grounds and particulars (reg 5.8(1) as in force immediately before 15 April 2013, subject to reg 23.36(2) item 4).

Evidence in answer

If the opponent files (or before 15 April 2013 serves) evidence in support of the opposition, the applicant or patentee must file any evidence in answer to the evidence in support within 3 months after being given (or being served with) the evidence in support.

Where the opponent does not provide any evidence in support, the applicant or patentee must file any evidence in answer to the statement of grounds and particulars within 3 months from the day the evidence in support was due to be filed (or before 15 April 2013 served).

(Reg 5.8(2)-(3) as in force immediately before 15 April 2013 subject to reg 23.36(2) item 4)

Evidence in reply

If the applicant/patentee files (or before 15 April 2013 serves) evidence in answer, the opponent intending to rely on evidence in reply must, within 1 month of receiving the evidence, file:

  • evidence in reply to the evidence in answer; or
  • a copy of a notice of intention to serve evidence in reply.

If a notice of intention is filed, the opponent must file the evidence in reply within 3 months of being given (or, before 15 April 2013, being served with) the evidence in answer.

(Reg 5.8(4) as in force immediately before 15 April 2013 subject to reg 23.36(2) item 4)

Filing evidence in oppositions commenced on or after 15 April 2013

Evidence is not always required or relied on in a procedural opposition.  Therefore, for oppositions commenced on or after 15 April 2013, once the statement of grounds and particulars has been filed, the parties will be asked to indicate if they wish to file evidence.  

Note: The provisions of reg 5.11(2), that documents mentioned in the statement of grounds and particulars must be filed with the statement, does not mean the documents are in evidence.  However, it is the current practice of the Commissioner when acknowledging the filing of the Notice of Opposition to inform the parties that she intends to direct that any documents accompanying the statement of grounds and particulars will be treated as evidence in support of the opposition.  That direction is then made when the Commissioner acknowledges that the statement has been filed.  If no such direction has been made, then any documents accompanying the statement that the opponent intends to rely on to establish the grounds of opposition must be filed with the evidence in support.

A party intending to file evidence will be required to specify the nature and significance of the evidence, and how long they will need to prepare the evidence.

A delegate will consider the information, and propose a direction under reg 5.12. Where a direction is given for a party to file evidence, the other party will normally be provided with a period in which to file responding evidence. For more information on directions for evidence in a procedural opposition, see 7.3.1.4 Time for Filing Evidence in a Procedural Opposition.

When evidence is filed, the opposition officer will acknowledge receipt to the parties and give a copy of the evidence to the other party.
