How to choose an intellectual property lawyer

  1. Check the lawyer’s status and any public discipline in the state bar or law society directory.
  2. Ask how many intellectual property law matters the lawyer handles each year, and who at the firm will do the work.
  3. Get the fee arrangement in writing: hourly, flat or contingency, and which costs are charged on top.
  4. Ask how and how often the firm will update you, and how fast it answers calls and emails.
  5. Read recent reviews for how the firm communicated and billed, not only for outcomes.
  6. For patents, check the lawyer is registered to practice before the patent office and has worked in your technical field.
  7. Meet more than one firm; many offer a short first consultation, sometimes free.
