About
I have extensive experience with all aspects of monetizing and enforcing patent portfolios, including negotiating license agreements, litigation, continued patent prosecution, and defending post-grant challenges at the United States Patent and Trademark Office. I lead my clients to efficient and lucrative resolutions.

My patent prosecution practice focuses on drafting patents and claims that are valuable (and someday enforceable) for my clients.

I also advise start-ups and small companies on all aspects of intellectual property protection and defense, including developing patent portfolios, trade secrets, responding to demand letters,

"Steve Lisa and Justin Lesko have both helped me navigate the process of filing my first provisional patent. As a novice patentee, they spent ample time with me; as I gained greater understanding of the entire patent process. The culture of this law firm is definitely centered on professionalism and integrity. Both of these gentlemen are easy to reach and effective in their craft. As I continue to build my business and promote my product as “patent pending”, I am at ease knowing that my legal rights are properly represented. Aside from feeling well advised, they have made every step of the process rewarding, easy, and pleasant. In the beginning, I was initially seeking a service… however, in the end, I found a lasting relationship that I would be proud to share with my friends and family. - Alex Babcock"

"Steve, Michelle, and Justin recognize that knowledge is power and they use it to their advantage. They are tough and they are creative. I wanted a partnership when I hired their firm and that is exactly what I got. As difficult as it is to be service-oriented in this business, Steve and his entire team were extremely thorough in their communication about my case, quickly and efficiently made recommendations that were on the mark without fail, and they were responsive in a manner that I could understand and be involved in when it was time to make a decision. Most of all, they are three of the most genuine and honest people you will ever hope to meet. - Mary Kay Grenier, Owner, HPL, LLC"
