IPC is a system of sorting inventions and their documents into technical fields covering all areas of technology and it is an effective search tool to determine the novelty and innovation of a technical solution. Currently, most countries in the world used IPC system for patent registrations and documents published in their countries. As a result, the search for patent documents of each country becomes much easier and convenient than ever before when each country adopted their own national patent classification.
