2.23.10.4 Evidence Required to Prove a Clerical Error or Obvious Mistake

Date Published

Where a request to correct a clerical error or obvious mistake does not contravene the provisions of sec 102, evidence is not required. However, supporting evidence will usually be required where the requested amendments are for the purpose of correcting a clerical error or obvious mistake and would otherwise not be allowable under the provisions of sec 102.

Generally, in order to establish the existence of a clerical error, evidence in the form of a declaration that fully explains the facts surrounding the clerical error and the amendment sought will be required.  

Where the amendment relates to the correction of an obvious mistake, evidence may be required to establish that the instructed reader of the specification would consider the mistake and the correction as satisfying the requirements of an obvious mistake.
