Prima IP


"I very strongly recommend Marcelo Sarkis handling intellectual property infringement and validity cases. He easily bridges scientific and legal arguments in patent litigation actions. I have worked with him on several pharmaceutical patent infringement cases and have been extremely impressed with his ability to focus on the key aspects of these cases and identifying a clear and effective strategy for his clients to move forward."

— Jonathan Dordick, Ph.D., Howard P. Isermann Professor of Biochemical Engineering at Rensselaer Polytechnic Institut

"Marcelo is more than a patent agent; he is an experienced strategic thinker who has been involved in leading patent cases, whether working extensively with expert witnesses or the essential issues of infringement and validity. Marcelo's unique experience over more than 20 years contributes to his unerring professionalism, both as a patent agent and advisor."

— Joseph Etigson, Joseph Etigson Professional Corporation

"I have worked as a scientific expert witness in many litigations during the past 12 years. I have worked with Marcelo in several of those cases and I have found him to be a complete professional with extraordinary insight into both legal and complex scientific matters…Marcelo has few peers."

— Michael Mayersohn, Ph.D., Professor, University of Arizona

"…have worked with him on several patent cases which have appeared before the Federal Court in Canada. These patents…were invalidated by the evidence in large part because of his excellent work. It is a pleasure working with Marcelo since he has significant knowledge of the scientific and patent issues of these cases and is quite thorough in preparing the evidence and also in briefing me for cross examinations. Marcelo has a gift for predicting the type of questions asked by the opposing side."

— Robert S. Langer, Ph.D., Institute Professor, Massachusetts Institute of Technology

"Marcelo was instrumental in assisting the company I was previously associated with, Biovail Corporation, in due diligence matters prior to acquiring third party IP assets, preparing invalidity and clearance opinions, detailed paragraph IV statements as well as drafting and successfully prosecuting key patent applications in Canada and the US. I have no problem recommending Marcelo for patent related matters."

— Rolf Reininghaus, Executive Director at Trimel Pharmaceuticals Corporation 

"I have worked with many lawyers and patent agents during my tenure in the legal industry. Marcelo is one of the few who stands out, not just that he is a great intellectual property law professional, but because he truly understands how to deliver excellent client service and what value means to his clients…He would always treat anyone he worked with the upmost respect and professionalism. Whether you are a potential client or colleague, I can guarantee that you will find value in working with Marcelo."
