The International Patent Classification (IPC) is a system used to categorize patents and utility models according to the different areas of technology they pertain to. Established by the World Intellectual Property Organization (WIPO), the IPC helps patent offices and researchers organize and search for patents more efficiently. It divides technology into sections, classes, subclasses, and groups, making it easier to identify similar inventions. The IPC is updated regularly to reflect advancements in technology and changes in industry practices. By providing a standardized classification, the IPC facilitates international cooperation in patent examination and helps ensure that inventors can protect their innovations globally.
