Combining a valuable and unique background in computer science and accounting, John J. Lucas is not your typical IP attorney. John handles every aspect of the litigation process for patent and trade secret matters from beginning to end. Although he is just a few years out of law school, John has packed a significant amount of litigation experience into that time, and he is always ready to help his clients with whatever legal need they may have. If he has a client who is either facing a potential lawsuit or considering litigation against an infringer, John conducts an analysis to look at the prospects of the case. He drafts and answers complaints and files motions for his clients, whether they are looking to get a summary judgment decision or a dismissal of an action.

With bachelor’s degrees in both information systems and accounting, John brings a perspective to his clients that many cannot. In addition to providing counsel on the technological and legal aspects of their cases, he is able to conduct a financial analysis as well. For John, IP litigation has been the perfect marriage of his backgrounds. John has a fascination with computer science and taught himself how to code at an early age. By the time he entered law school, John knew IP was the right path. 

John’s clients come from a spectrum of technology-based sectors, including telecommunications, consumer products, and medical equipment. For John, the most enjoyable aspect of his job is the people he works with on a daily basis. He values meeting new clients and learning about the ins and outs of their industry. John enjoys going outside of his comfort zone and having the opportunity to study new fields of technology.

When he’s not at work, John enjoys spending time outdoors, whether he is skiing, scuba diving, or mountain climbing. In fact, after his law school graduation, John climbed to the summit of Mount Kilimanjaro.
