Patent prosecution is distinct from patent litigation which relates to legal proceedings for infringement of a patent after it is granted.
The main advantage of proceeding via the PCT route is that the option of obtaining patents in a wide range of countries is retained, while the cost of a large number of applications is deferred.The Patent Cooperation Treaty (PCT) is operated by World Intellectual Property Organization (WIPO) and provides a centralised application process, but patents are not granted under the treaty.The application, called an international application, can, at a later date, lead to the grant of a patent in any of the states contracting to the PCT.A standard patent application is a patent application containing all of the necessary parts (e.g.a written description of the invention and claims) that are required for the grant of a patent.Once the patent specification complies with the laws of the office concerned, a patent may be granted for the invention described and claimed by the specification.
The process of "negotiating" or "arguing" with a patent office for the grant of a patent, and interaction with a patent office with regard to a patent after its grant, is known as patent prosecution.
Filing and prosecuting an application at a regional granting office is advantageous as it allows patents in a number of countries to be obtained without having to prosecute applications in all of those countries.
The cost and complexity of obtaining protection is therefore reduced.
The application may either be filed directly at that office, or may result from a regional application or from an international application under the Patent Cooperation Treaty (PCT), once it enters the national phase.
A regional patent application is one which may have effect in a range of countries.
The European Patent Office (EPO) is an example of a Regional patent office.
