Sunnyvale, California

Patent attorneys in Sunnyvale

Sunnyvale, California is home to 158 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 Nokia, OneNav, Inc., and Synopsys, Inc..

Common questions

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

How many USPTO practitioners list a Sunnyvale office?

158 USPTO-registered patent practitioners list a Sunnyvale 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 Sunnyvale practitioner remotely?

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