What does ipc on the nameplate mean?

What does IPC on the nameplate mean? IPC is the abbreviation of "international patent classification" in English, which means international patent classification. It is a unified classification system for sorting out patent application information, facilitating patent inquiry and research, and promoting international technical exchanges. IPC is managed by the World Intellectual Property Organization and adopted by most countries in the world. It is considered to be the most widely used patent classification system in the world.

IPC systematically classifies patented technologies in different ways, including mechanical engineering, electric power and chemistry. When applying for a patent, it is necessary to declare relevant technologies according to IPC classification, so that the examination department can quickly find relevant technical documents, thus saving examination time. In patent query, we can also search according to IPC classification, so as to quickly find relevant patent technical documents.

IPC plays an important role as a bridge in international technical exchange. Different countries or regions may have different technical practices, but IPC classification can unify technical languages and promote technical exchanges and cooperation. At the same time, the application of IPC also provides an important support for the world intellectual property protection mechanism and plays an important role in protecting patent rights and interests.
