Intellectual property lawyer | Mar 28

Relationship: Fellow lawyer in community

"I endorse this lawyer. With several hundred published answers to consumer questions and several extremely well written Avvo Legal Guides, and recommendations from other attorneys, it is easy to see that attorney Caldwell is extraordinarily bright in the field of copyright law - I especially like his "Chicken Soup" tips on copyright law. If you have an intellectual property question and his office is anywhere near you, then he is your answer. I highly recommend him to you."

Avvo Rating

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

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.
