Ben entered the practice of law after serving in the U.S. Navy as a Naval Flight Officer. During his naval service, Ben was an instructor at the U.S. Naval Academy, his alma mater. Following active duty and prior to becoming an intellectual property attorney, Ben managed an electro-optics engineering center and also worked as a program manager for a computer systems company.

Ben represents a variety of clients in various technical areas, including computer (software, artificial intelligence (AI), machine learning), electrical, mechanical, optical, and electro-mechanical arts. His clients include automotive, software and diagnostics companies, maritime, energy systems, metal and plastics fabrication, and medical device companies. Ben has prepared numerous U.S. and international patent applications including those directed to software and electrical inventions relating to cellular telephone technology, programmable logic controllers, software to control lasers for real-time chemical analyses of pharmaceuticals and consumables, junction box controllers, fiber optic components, and business methods involving various levels of code.

Ben has obtained hundreds of patents for his clients in the United States and around the world, and has also prepared dozens of opinions, including patentability, clearance, infringement/non-infringement, validity/invalidity, due diligence, pre-litigation, and many other types of opinions for his clients.

In addition to patents, Ben helps his clients protect their other intellectual properties such as copyrights, trademarks, trade dress, and trade secrets. Ben advises his clients with respect to these and related business matters such as licensing, employee issues, corporate set-up, and tax credit qualification and strategy. Like patent matters, Ben has also provided many opinions regarding trademarks, copyrights, other forms of intellectual property.

Ben has litigated intellectual property and related business issues in federal and state courts and at the Trademark Trial and Appeal Board (TTAB) and the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office as well as domain name disputes via the National Arbitration Forum using Uniform Dispute Resolution Procedures (UDRP). He has experience litigating contentious corporate management disputes in close corporations, and leverages that experience to foreclose corporate structures that germinate such disputes.

Ben is a member in good standing of numerous state and federal bar associations. Ben’s South Carolina Bar activities include CLE OnDemand webinars such as “Intellectual Property in the Fast Lane,”, and a seminar entitled “Patenting a Software-Related Invention After Alice Corp. et al.” He has also recently presented seminars regarding Artificial Intelligence to various professional organizations such as AUTM and the Tennessee Intellectual Property Law Association (TIPLA).
