Recording Assignments & Other Formalities

Assignments of Australian Patents, Trade Marks and Designs

An application to record the assignment of an Australian patent, trade mark or registered design must be supported by documentary evidence of the assignment (eg Deed of Assignment). The assignment deed should show:

  • The full name(s) and address(es) of the assignor(s) and assignee(s);
  • Details of the patent/trade mark/design being assigned (ie. at least the number); and
  • Provide the date of the assignment.

The assignment deed should also be signed by an authorised representative of each party. The original signed copy is not required: that is, a simple copy will be sufficient.



Changes of Name and/or Address

An application to record a change in the name and/or address of an owner or applicant of an Australian patent, trade mark or registered design does not usually need to be supported by any documentation evidencing the change. However, for changes of name, a simple copy of the official Certificate of Change of Name is helpful.

IP Australia does not record address details for inventors named on patents or authors (designers) of designs.  Accordingly, changes to inventor/designer addresses cannot be officially recorded.
