About this directory
Choose a patent attorney with the same diligence you’d apply to any senior professional.
Every patent attorney listed in our directory has been cross-checked against state bar records — license number, admission date, practice areas, and any disciplinary history are surfaced on the profile, never hidden. The state with the largest population of patent attorneys is California, but you can drill into any U.S. jurisdiction below.
LawyersListed is editorially independent from the attorneys we list. Search rankings, ratings, and review screening are not influenced by advertising spend. Featured placements are clearly disclosed, and we never collect a referral fee out of your attorney's retainer.
Not sure if your matter is even a patent matter? Post your situation to our free public Q&A — anonymously, no card required — and a bar-verified attorney will usually respond within a few hours.

Frequently asked
Frequently asked questions about patent lawyers
How do I find a verified patent attorney?
Use the search above to filter patent attorneys by state, city, language, and consultation fee. Every listing on LawyersListed is cross-referenced with the relevant state bar — license number, admission date, and disciplinary status are surfaced on the profile, not buried.
Is it free to contact a patent lawyer here?
Yes. Browsing profiles, reading authentic reviews, sending a first message, and asking a public legal question are always free. You only pay if you choose to book a paid private consultation — and the fee is displayed up front before you confirm.
How is a patent attorney usually paid?
It depends on the matter. Most patent attorneys bill hourly, on a flat-fee basis for defined work, or on retainer for ongoing matters. Every LawyersListed profile lists the consultation fee up front; the long-term fee structure is something to ask about during that consultation.
How long does it take to book a patent consultation?
Most active attorneys publish a live calendar with same-week openings; many show same-day availability for urgent matters. Payment is held in escrow until the consultation completes, so funds release only after you’ve met with counsel.
What should I bring to a patent consultation?
A short written summary of what happened (dates, parties, dollar amounts), copies of every document you already have (contracts, letters, photographs, medical records — whatever applies), and three concrete questions: How have you handled a matter like mine? What is the realistic range of outcomes? What will this cost end to end?
Does LawyersListed take a referral fee from my patent attorney?
No. We never collect a referral fee or a percentage of an attorney’s retainer. Attorneys pay LawyersListed a flat platform fee for premium features; that arrangement is fully separate from any fee you pay your attorney for legal services.
