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

No, but the lawyer must be licensed in your state (or, for federal matters such as immigration, in some state). A local office makes meetings and court appearances easier, so proximity is one of our factors.
