These pages have been assembled from the bits and pieces I have found useful in advising my clients about their intellectual property rights.

I have a strong background in the commercial side of the exploitation of patents trade marks and designs.  I have been exposed to the patent system from the time I graduated in Chemical Engineering in 1979 with my focus on the subject increasing since that time.

In 1981 I became involved in the establishment of a "high-tech" membrane filtration company known as Memtec Limited, first as their Technical Advisor and then as their Intellectual Property Manager.

In 1990, I "joined the profession", as it were, at Pizzey and Company (as it then was), and joined the firm at which I am currently employed, AHEARN FOX, in 1998.  I qualified as a registered patent and trade marks attorney (two separate qualifications) in 2000, graduating from the very first class which emerged from the newly established Institute of Patent and Trade Mark Attorneys' Academy.
