Robert D. Leonard



Emblematic of Rob’s approach is his dedication to close communication with his clients. He continuously considers his approach to improve communication and efficiency, and to provide innovative ways to serve clients and deliver optimal IP counsel and value. Having worked at two large, publicly traded companies in an in-house capacity, Rob understands the client’s perspective.

Rob works shoulder-to-shoulder with clients, focusing on strategic patent prosecution with an eye toward patent monetization. His approach includes evaluating the technical and legal aspects of patent infringement and validity during the prosecution phase, leading to the creation of high-value assets. He is experienced in patent portfolio development and strategy, patent acquisition due diligence, patent divestitures, and mining of currently owned patent assets. 

Rob’s practice includes patent prosecution in anticipation of litigation, prosecuting family members of patents in litigation, developing claim charts and patent validity and infringement analysis, and counseling clients on portfolio strategy. Rob directs worldwide patent prosecution, particularly in Europe and Asia. Rob also handles various post grant proceedings before the USPTO, including Ex Parte Reexamination and Inter Partes Review (IPR) proceedings.

Previous Work and Industry Experience

Prior to joining the firm, Rob worked as a process engineer manufacturing specialty chemicals and pharmaceuticals. He also designed and constructed process equipment and associated control systems and electronics (cell culture reactors, fermentors, and filtration units) for several large biopharmaceutical companies.

Rob is a travel and exercise enthusiast. Running and CrossFit helps him keep up with his two daughters. Skiing, SCUBA, and sailing are what he looks forward to when not in the office.
