Chicago, Illinois

Patent attorneys in Chicago

Chicago, Illinois is home to 1,891 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 McDonnell Boehnen Hulbert & Berghoff LLP, Banner and Witcoff, Ltd, and Taft Stettinius & Hollister LLP.

Common questions

Do patent attorneys in Chicago 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 Chicago tend to track the broader Illinois legal market.

How many USPTO practitioners list a Chicago office?

1,891 USPTO-registered patent practitioners list a Chicago 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 Chicago practitioner remotely?

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