About Cassan Maclean

Cassan Maclean is an Ottawa intellectual property firm that practices exclusively in patents, trademarks, copyright, industrial designs, and domain name disputes. The firm includes Cassan Maclean IP Agency Inc., a registered patent and trademark agency that handles filing and prosecution work, and its lawyers also provide IP legal counsel and represent clients in Federal Court litigation. Founders Lynn Cassan and Scott Maclean bring more than 60 years of combined experience in drafting and prosecuting patent applications in electronics, communications, and biotechnology, fields the firm still concentrates on today.

Cassan Maclean traces back to a predecessor firm, where Lynn Cassan, an electrical engineer who worked at Bell Northern Research (later Nortel Networks) before earning a law degree, became partner with Scott Maclean in 1993. The current team includes registered patent and trademark agents whose backgrounds mirror that technical focus: one concentrates on trademark prosecution and domain name disputes and advises on Quebec's French language labelling rules, while two others handle patent work in biochemistry and biotechnology, one with an earlier research background in cardiology. The office is at 190 O'Connor Street in downtown Ottawa.
