Richard T. Timmer is a Senior Patent Agent specializing in the areas of chemistry, biotechnology, and medical devices. Rick has over 25 years of experience in the chemical and life sciences industries, including patent preparation and prosecution, as well as the management of patent portfolios from biotechnology start-ups to multinational pharmaceutical companies. Rick has drafted patent applications related to materials science, polymer science, pharmaceutical formulations, novel and repurposed drugs, and synthetic organic chemistry; biotechnology, including inventions related to human and animal health, as well as plant biotechnology; medical devices; software; and consumer products.

Rick has experience managing and prosecuting company patent portfolios, diligence efforts, deal sourcing, and licensing negotiations, both from an in-house position working with outside counsel and from the perspective of a legal practitioner advising clients from within a law firm environment. He has experience leading research programs in both the academic and industry worlds, teaching undergraduate and graduate courses at leading research universities, and leading investment rounds for early-stage biopharma companies. Rick has worked with many prominent universities and research hospitals, and he understands the complex needs and demands of university technology transfer and licensing.

Rick is an experienced educator, having taught classes to both undergraduates and graduate students, including organic chemistry, molecular biology, and advanced laboratory methods protein research. He has also mentored students on patent matters for the Emory/Georgia Tech TI:GER program. Rick also mentors for the Parker H. Petit Institute for Bioengineering and Bioscience at Georgia Tech and frequently engages with graduate students and post-doctoral students one-on-one and formal seminars on transitioning from the research world to a career in intellectual property. He also has presented at national meetings and in webinars on patent concerns and strategy around drug repurposing, pharmaceutical development, and CRISPR technologies. During his time in academia, Rick was a co-PI on numerous grants, including R01 and P01 grants, as well as being awarded an individual NIH Postdoctoral NRSA grant, as well as various university research awards as both an undergraduate and graduate student.
