Seattle, Washington

Patent attorneys in Seattle

Seattle, Washington is home to 668 USPTO-registered patent practitioners. Working with a local practitioner can streamline in-person meetings for invention disclosures, signing inventor declarations, and reviewing prior-art search results — but every USPTO practitioner is licensed to practice nationally, so a non-local choice is also valid. Local firms with the most USPTO-registered practitioners include Christensen O'Connor Johnson Kindness PLLC, Davis Wright Tremaine LLP, and Seed Intellectual Property Law Group LLP.

Common questions

Do patent attorneys in Seattle cost more than the national average?

Patent attorney fees vary primarily by experience and complexity of the invention, not by city. A typical provisional patent application in the US runs $1,500 to $5,000; a non-provisional utility filing runs $5,000 to $15,000. Hourly rates in Seattle tend to track the broader Washington legal market.

How many USPTO practitioners list a Seattle office?

668 USPTO-registered patent practitioners list a Seattle mailing address on the OEDCI roster. You can sort by firm size and contact each directly using the phone numbers shown.

Can I work with a Seattle practitioner remotely?

Yes. All filings happen through USPTO's electronic Patent Center — no in-person presence is required. A Seattle-based practitioner is convenient for local inventor signings and in-person meetings but not a requirement for representation.
