Troy A. Groetken is a distinguished lawyer based in Chicago, Illinois. With over twenty years of experience, Mr. Groetken is a leading and highly regarded attorney in patent law and litigation as recognized by Lawyer Monthly, Super Lawyers Magazine, Best Lawyers and Law Bulletin Publishing Company, among others. He is currently a Shareholder and Board Member with McAndrews, Held, & Malloy, Ltd. where he focuses on patent and trademark procurement, as well as enforcement and transactional matters in the advanced chemical, small-molecule pharmaceutical, and biotechnological disciplines.

As he tells it, Mr. Groetken knew he wanted to go into patent law starting when he was very young:

When I was growing up, my neighbor was a patent attorney and I always found that to be really cool. He had incredible and unique gadgets from various projects and I wanted to be just like him.

Mr. Groetken received his B.S. degree in pharmaceutical sciences from Drake University with an eye toward combining his interest in science with his interest in patent law. He went on to obtain his Juris Doctorate in intellectual property law from Drake University Law School, and his Master of Laws from The John Marshall Law School. After working as a clinical consultant pharmacist for a number of years, he began to practice patent law in the scientific arena.

Outside of his extensive experience in both the scientific, clinical and legal fields, the recipe to Mr. Groetken’s success lies in his excellent client service. He always makes sure that his clients are well-informed regarding substantial current developments and future developments within patent law as well as the practical outcomes that should be considered by each particular client individually. There are constantly new issues, interpretations, and applications of U.S patent law and it is important to Mr. Groetken that his clients understand how their businesses could be impacted.

Mr. Groetken is also widely recognized for his writing and presentations on topics within the intellectual property field, including patent protection and prosecution, inter partes review matters, global litigation, alternative litigation strategies, and patent best practices with respect to multi-national procurement, licensing, and divestiture of intellectual assets. He is known globally as the “go-to” intellectual property attorney for Fortune 100 and 500 firm clients regarding complex intellectual property matters involving patent portfolio development, implementation and enforcement, and multi-jurisdictional intellectual property integration issues. Mr. Groetken regularly assists clients with a variety of technical disciplines involving the chemical, pharmaceutical and biotechnological arts, encompassing new drug entities, generic pharmaceuticals, biotechnological sciences, including protein and recombinant technologies, food-based technologies, animal compositions, medical devices, and renewable energies, among others.

As a leader in his field, Mr. Groetken keeps his eye on prevailing trends in patent law. In particular, his firm is currently paying attention to the effects of the Halo Decision, a Supreme Court case his firm was involved in that has swung the pendulum in favor of patent holders. He noted:

Right now we are watching the Halo Decision's effects on treble damages, which allow courts to triple the amount of damages awarded to a plaintiff. We are also utilizing and assisting our clients with a number of critical PTAB decisions with respect to key IPR and PGR issues. Finally, a number of ongoing interpretations of what constitutes infringement (e.g., singular component versus multi-component incorporation outside of the United States), obviousness, patent subject matter eligibility and the like are always important to our clients from both offensive and defensive viewpoints.

After over two decades dedicated to his field, Mr. Groetken shows no signs of slowing down. Looking to the future, he anticipates continuing to work within the pharma, biotech, and chemical patent world, providing the excellent customer service and industry expertise for which he has become known.
