List of national legal systems
Common law is currently in practice in Ireland, most of the United Kingdom (England and Wales and Northern Ireland), Australia, New Zealand, Bangladesh, India (excluding Goa), Pakistan, South Africa, Canada (excluding Quebec), Hong Kong, the United States (on a state level excluding Louisiana), and many other places. In addition to these countries, several others have adapted the common law system into a mixed system. For example, Nigeria operates largely on a common law system, but incorporates religious law.
Unified Patent Court
Discussions on a "Protocol to the Agreement on a Unified Patent Court on Provisional Application" were closed in September 2015. The protocol was signed by eight states on 7 October 2015: Denmark, Germany (subject to ratification), Hungary, France, Luxembourg, Slovenia, Sweden and the United Kingdom. Provisional application allows the hiring of judges and moving to the court premises. Provisional application starts when 13 states (including Germany, France and the United Kingdom) have ratified the Unified Patent Court Agreement or when they have indicated to have finished their parliamentary process.
