Patent attorneys in Philadelphia

Philadelphia, Pennsylvania is home to 505 USPTO-registered patent practitioners.

Common questions

Do patent attorneys in Philadelphia 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 Philadelphia tend to track the broader Pennsylvania legal market.

How many USPTO practitioners list a Philadelphia office?

505 USPTO-registered patent practitioners list a Philadelphia 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 Philadelphia practitioner remotely?

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