Where Delaware's patent practitioners work

Employers with the most registered practitioners

Law firms and companies, as written on the USPTO roster. Includes both attorneys and agents.

Patent attorney or patent agent?

Both are registered with the USPTO and can prepare and prosecute patent applications. To register, either must show scientific or technical training and pass the USPTO's registration exam. A patent attorney is also a licensed lawyer, so they can give legal advice beyond the application itself, such as on licensing, infringement claims or lawsuits. A patent agent isn't a lawyer and works only on matters before the USPTO.
