  • Daniel Nathan Ballard

    I've read nearly a hundred of Attorney Lang's responses to Avvo questions. Without exception, his responses are legally sound, insightful, wise and -- most important -- business savvy. I strongly endorse him and would not hesitate to recommend him to anyone seeking intellectual property advice.
