Kevin prepares and prosecutes patent applications in various electronics and computer-related technologies, with significant experience in video and content delivery, internet advertising, and telecommunications, as well as wireless, software and applications, and medical devices.

Kevin approaches patent prosecution, portfolio development, and IP licensing strategy from a global enforcement perspective, as formed by his experience with patent licensing and litigation. In addition to patents, Kevin has prosecuted trademarks at the USPTO, advised clients on global trademark strategies, and supported IP enforcement actions, including claims of trademark misappropriation and unfair competition.  

Before joining Haley Guiliano, Kevin served as in-house counsel for a technology company in Philadelphia. During that time, Kevin led teams in evaluating patent portfolios, reverse engineering competitors’ products, and investigating potential infringement in support of several successful licensing campaigns. His practice emphasizes working with technology experts in litigation and Inter Partes Review proceedings, an approach developed through involvement in dozens of large patent infringement trials and proceedings at the USPTO Patent Trial and Appeal Board.

In addition, Kevin is an avid blog contributor, writing about IP-related subjects such as football helmet designs, infrared mobile phone cameras, 3-D film production, and policy and strategies surrounding standard-essential patents and subject matter eligibility under Alice and 35 U.S.C. § 101.
