Outstanding Patent Attorney

I worked with Derek and his company on navigating legal challenges related to patent law. After describing the challenges my company and I were having Derek rolled up his sleeves and got to work. From the first initial conversation and throughout the entire process Derek displayed first rate professi...onalism, was very timely and really helped simplify the legal complexities with his level of expertise. I had an amazing experience through and through and plan to use his services for future Patent needs. Would highly recommend him and his companies services to anyone.

Best lawyer to handle anything copyright

Derek is absolutely amazing. I needed to copyright my paintings and had no idea how to do that on my own. I sought out Derek to handle all of it. He answered each and every question I had in a very timely manner. He’s very responsive and knowledgeable in his field and I couldn’t have asked for a bett...er experience. If I could give more than 5 stars I would.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
