2.22.5.6 Proposed Amendments are not Allowable

Date Published

Where a response to a re-examination report includes a request for leave to amend the specification, and the amendments are not allowable, the report on the request for leave to amend under sec 104(2) and reg 10.2(1) should proceed as a separate action from the re-examination process.  Thus, any adverse report on the allowability of the voluntary amendments should not comment on the substantive issues that were raised in the re-examination report.  A subsequent re-examination report should not be dispatched until the allowability issue has been resolved.  In particular, examiners should not issue a re-examination report on the specification as proposed to be amended, if the amendments are not allowable.

Where an adverse report on the amendments is issued, the applicant or patentee is given 1 month in which to respond and informed that if no response is received within this time, the Commissioner may set the matter for a hearing to consider concurrently:


  • refusal or revocation of the patent or patent application on the basis of the re-examination report; and

  • refusal of the request for leave to amend on the basis of the adverse report under reg 10.2(1).


If a response to an adverse report on the allowability is received and a subsequent adverse report is warranted, then a further month should be given for a response.  The adverse report should also include the above comments.

Once allowable amendments have been filed, the procedures outlined in 2.22.5.5 Proposed Amendments are Allowable should be followed.

Note: Patent Oppositions should be consulted before any adverse report on the allowability of the voluntary amendments is issued.
