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, Klarquist Sparkman LLP, and Compass IP Law PC.

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.
