Common questions

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

How many USPTO practitioners list a Irvine office?

598 USPTO-registered patent practitioners list a Irvine 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 Irvine practitioner remotely?

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