R. Benjamin Cassady


Ben Cassady focuses his practice on patent litigation at U.S. district courts and before the U.S. International Trade Commission (ITC). He works on a wide variety of cases involving technologies such as smart phones, vehicle tracking systems, microprocessors, touch panels and touch screens, and user interface design.

Mr. Cassady's litigation experience includes drafting Markman briefs and preparing technical tutorials; interfacing directly with experts to draft technical reports; preparing witnesses for depositions and trial; and briefing motions on a variety of topics, including motions to dismiss, stay, sever, and transfer. He has developed tailored litigation strategies for defending clients by combining his experience with motion practice before district courts and knowledge of post-grant proceedings at the U.S. Patent and Trademark Office (USPTO).

Mr. Cassady also assists with client counseling, due diligence, and pre-litigation matters, including drafting noninfringement and invalidity opinions. He has experience preparing and drafting ex parte reexamination and
inter partes review (IPR) requests.

Mr. Cassady's technical background includes various fields such as mechanics, thermodynamics, optics, and quantum mechanics. He has significant technical knowledge in the areas of voice recognition, touch panel manufacturing, GPS systems, and other cutting-edge technologies. For example, he conducted detailed analysis of Android source code to determine the mechanisms by which users interact with the touch screens of smart phones, and he researched the development of voice recognition systems for use in consumer devices.
