1.4 Important Patent Offices

1.1.1         IP5

The so-called IP5 refers to the five largest patent offices in the world, including United States Patent and Trademark Office(USPTO), European Patent Office (EPO), State Intellectual Property Office (SIPO) from China, Japan Patent Office (JPO), and Korean Intellectual Property Office (KIPO).

 

USPTO, SIPO, JPO, and KIPO issues patents on behalf of governments from USA, China, Japan, and Korea, respectively. These patents are automatically enforced in these countries once granted for the terms of the patents. However, EPO issues a special kind of EP patents that are not automatically enforced by its member states. EP patents are enforced by the member nations individually. This creates numerous problems since lawsuits regarding validity or infringement often have to be conducted in all member states to be effective.
