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

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

• How much does it cost to hire Donald for a ip case?

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

• Does Donald offer a free consultation?

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

• How long do ip cases in District of Columbia typically take?

  Simple ip 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. Donald gives a realistic estimate for your facts at the consult — vague answers here are a red flag.

• Can Donald take my case if I'm outside Washington?

  Donald is licensed in District of Columbia. Matters governed by District of Columbia law are the natural fit. Out-of-state matters are handled case-by-case, sometimes with local co-counsel. Ask during intake — Donald 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 Donald?

  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. Donald will filter what matters — over-preparing at intake is always cheaper than needing a second meeting.

• Is Donald accepting new ip clients right now?

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