History

• Cullens was established in 1936 by George Russel Cullen under the name GR Cullen & Co. 

  George Cullen was registered as a patent attorney on 24 April 1922. He filed his first patent application for a client in Brisbane on 24 March 1924 for an engineer from Eagle Street in Brisbane.

  The firm was a family practice with George Russell Cullen as the attorney and Gwen Cullen, one of George’s two daughters working on the administrative side and witnessing the patent applications. George’s second daughter, Mavis Cullen was tragically killed in a tram accident in Brisbane and George passed away soon thereafter at the age of 58 in 1948. Gwen Cullen passed away in 1989.

  In 1948 GR Cullen & Co was bought by a firm in Melbourne, AJ Callinan and the practice continued operation under the name GR Cullen & Co, managed by John Callinan.

• In 1957 Joseph Stephenson, a patent examiner and registered patent attorney from Canberra then joined GR Cullen & Co. around 1957 and became a partner together with Mark Callinan. In 1961 Mark Callinan was bought out by Robert R Michel. Michel was a patent examiner and qualified patent attorney from Melbourne.

  Through the years from 1961, the firm grew from a partnership of two, to a firm having almost 20 attorneys, removed the ‘GR’ from the name of the firm in the 1990’s and became known as ‘Cullen & Co’ or simply ‘Cullens’.

  In June 2009, the firm officially adopted the name Cullens. Cullens now has six partners of various technical backgrounds, supported by a number of attorneys and administrative staff.

• The Cullen eagle logo is derived from an armorial coat of arms and embraces the stars of the Southern Cross.  The Cullen eagle is represented in Australia’s national colours of green and gold.
