Portland, Oregon

Patent attorneys in Portland

Portland, Oregon is home to 324 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 Klarquist Sparkman, LLP, Marger Johnson McCollom, P.C., and Alleman Hall & Tuttle LLP.

Common questions

Do patent attorneys in Portland 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 Portland tend to track the broader Oregon legal market.

How many USPTO practitioners list a Portland office?

324 USPTO-registered patent practitioners list a Portland 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 Portland practitioner remotely?

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