Patent attorney

A patent attorney is an attorney who has the specialized qualifications necessary for representing clients in obtaining patents and acting in all matters and procedures relating to patent law and practice, such as filing patent applications and oppositions to granted patents. The term is used differently in different countries, and thus may or may not require the same legal qualifications as a general legal practitioner.
The titles patent agent and patent lawyer are also used in some jurisdictions. In some jurisdictions the terms are interchangeable, while in others the latter is used only if the person qualified as a lawyer.
