Working with a new patent attorney should feel structured. Here's how the first two conversations with Sean usually go, from the moment you request a consult to the day representation begins.

Sean discusses fees during intake so the arrangement fits the matter. Contingency, hourly, and flat-fee options are all common in patent practice — ask which fits.

• How much does it cost to hire Sean for a patent case?

  Cost depends on the type of matter, the fee model (contingency, flat, hourly), and how contested the case becomes. Sean walks through the likely range during the consult so there are no surprises.

• Does Sean offer a free consultation?

  Sean charges for the initial consult; that fee is credited toward representation if you retain Sean's office. Some patent attorneys offer free consults — check Sean's current terms during booking.

• How long do patent cases in Minnesota typically take?

  Simple patent matters can wrap in a few weeks; disputed cases can run 6–18 months from intake to resolution, longer if the matter goes to trial. Sean gives a realistic estimate for your facts at the consult — vague answers here are a red flag.

• Can Sean take my case if I'm outside Plymouth?

  Sean is licensed in Minnesota. Matters governed by Minnesota law are the natural fit. Out-of-state matters are handled case-by-case, sometimes with local co-counsel. Ask during intake — Sean will tell you if the case is a fit or refer you to someone closer to your court.

• What should I bring to my first meeting with Sean?

  Bring every document that touches the dispute: contracts, correspondence, police or medical reports, filed pleadings, invoices, photographs, insurance letters. Also bring a written timeline of what happened, in your own words. Sean will filter what matters — over-preparing at intake is always cheaper than needing a second meeting.

• Is Sean accepting new patent clients right now?

  Sean's intake status shifts week to week. Submit the form; the office will confirm availability or refer the matter out.
