Common questions

Do patent attorneys in Gaithersburg 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 Gaithersburg tend to track the broader Maryland legal market.
How many USPTO practitioners list a Gaithersburg office?
108 USPTO-registered patent practitioners list a Gaithersburg 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 Gaithersburg practitioner remotely?
Yes. All filings happen through USPTO's electronic Patent Center — no in-person presence is required. A Gaithersburg-based practitioner is convenient for local inventor signings and in-person meetings but not a requirement for representation.
