Patent attorneys in San Francisco

San Francisco, California is home to 854 USPTO-registered patent practitioners.

Common questions

Do patent attorneys in San Francisco 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 San Francisco tend to track the broader California legal market.

How many USPTO practitioners list a San Francisco office?

854 USPTO-registered patent practitioners list a San Francisco 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 San Francisco practitioner remotely?

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