1, International Patent Classification (IPC) is an effective classification method, which classifies patents according to certain standards, making patent retrieval easier and more effective.
2. The hierarchical structure of international patent classification includes five levels: department, major category, minor category, major group and small group.
3.IPC symbols use letters to represent large categories and numbers to represent small categories.
4.IPC symbols also include capital letters, which are used to represent large groups and small groups.
5.IPC symbols can also contain special characters, such as-and/,to further describe the categories and characteristics of patents.
6. In IPC, departments are the highest classification, and * * * is divided into 8 departments, namely A, B, C, D, E, F, G and H.
7. Each department is divided into several categories, and each category is subdivided into several subcategories.
8. Under small categories, it can be further divided into large groups and small groups.
Application fields of international patent classification;
1, patent retrieval: IPC provides a unified classification system, which makes patent retrieval more convenient and faster. By using IPC symbols, patent searchers can quickly locate the topics and categories of related patents, which improves the retrieval efficiency and accuracy.
2. Patent classification: IPC is an important basis for patent classification. By classifying patents, we can better organize and sort out patent information in related technical fields, and provide a basis for further technology research and development and market analysis.
3. Management and protection of patent rights: IPC provides an important reference for the management and protection of patent rights. By using IPC symbol, the scope and boundary of patent protection can be accurately determined, which is helpful for the smooth application, examination and rights protection of patent rights.
4. Technology research and development: IPC provides important guidance for technology research and development. By using IPC symbols, we can quickly understand the development status and trends of related technical fields, and provide directions and ideas for further technical research and development.
5. Intellectual property trade and cooperation: IPC is an important reference for international intellectual property trade and cooperation. By using IPC symbols, we can quickly understand the distribution and layout of patents in related technical fields, and provide basis and support for intellectual property transactions and cooperation.
