Profile

Greg Hlatky is a Technical Advisor in the Intellectual Property section.

Prior to joining Chamberlain Hrdlicka, Greg spent many years as a principal R&D investigator with major chemical companies. He is an inventor on several highly-cited, groundbreaking patents in ionic single-site catalysts, hafnium-based metallocene catalysts and constrained-geometry catalysts for olefin polymerization, all of which are now used commercially. In total, he is an inventor on 40 US patents as well as an author of over 30 literature publications.

Along with his research activities, Greg has worked extensively at the interface between technology and intellectual property, assisting with IP steering, patent prosecution, litigation and interference cases. Skilled in patent searching, he has performed current awareness, patent landscaping and novelty and freedom-to-operate searches in diverse fields such as petrochemicals, chemical engineering, the production, processing and applications of condensation, addition and natural polymers, catalysis, artificial sweeteners and preservatives.
