Why a patent agent instead of a patent attorney?

An attorney is able to represent you in court proceedings in case your patent is infringed, but their fees are significantly higher. In terms of prosecuting patent applications, both patent agents and attorneys are equally qualified in the eyes of the Patent Office. Many people seeking a patent don't need an attorney.
