It should come as no surprise to you to learn that Omar is an avid collector and lover of wine.

The expert in patent matters that he is, it’s really no wonder: having a great wine cellar is not unlike managing an IP portfolio. Both require a great attention to detail, an intuition for quality, and extensive research. Both require tireless vigilance and ongoing expert management. And both require a vision for a collection that’s greater than the sum of its parts.

Omar has been honing these skills for over 25 years as a patent agent and global IP strategist extraordinaire. Registered as a Canadian and United States patent agent, Omar has extensive experience in drafting and prosecuting iron-clad patent applications domestically and globally for some of the world’s largest and most reputable companies, in areas such as pharmaceuticals, biomedical devices, water treatment, agriculture, urethane chemistry, and industrial tailings treatment processes. He is consistently ranked in IAM Patent 1000, a guide that identifies the very top patent professionals around the globe.

When clients look for assistance in managing and co-ordinating their international patent portfolios, they turn to Omar for advice. Omar also has significant experience in drafting freedom-to-operate and validity opinions, providing support in negotiating and drafting IP licences, and offering invaluable advice in patent litigation matters.

A true cosmopolitan (and Aeroplan points hog), Omar really enjoys travelling. He marks off one or two travel venues from his bucket list each year, and always returns with new inspiration that he shares via culinary expression with his friends, family, and colleagues.
