27 April 1979
27 April 1995


The patent for the invention Electrode for Human Cochlea (application number 1979046563) was granted on 1 December 1983. This was an important milestone in the development of the bionic ear (cochlear implant). The patent was awarded by the Australian Patent Office in respect of the application (on 3 May 1978) by the University of Melbourne for an invention entitled "improved electrode array", with the inventors named as Graeme Clark, James Patrick and Quentin Bailey. The effective date of the patent was recorded as 27 April 1979. A further application was made on 7 March 1983 by Raymond David Marginson, Vice-Principal, on behalf of the university. The patent expired on 27 April 1995.


In the original application for the patent, the Electrode for Human Cochlea was described as "electrode array comprising a flexible biologically inert tube, a number of electrodes being conducting bands located at predetermined spaced distances along a portion of the length of the tube, the electrodes lying, generally, within the diameter of the tube and a conducting wire associated with each electrode passing to the interior of the tube through a slot, aperture or the like in the tube at a position beneath the associated electrode to which the wire is connected and along the length of the tube to one end thereof."
Tatlock and Associates, Patent and Trademark Attorneys, acted for the university in respect of the initial patent application. Sandercock, Smith and Beadle, patent attorneys, acted for the university in respect of the further application made by Raymond Marginson on 7 March 1983.
