Patent Classification Systems

Patent classification systems are structured frameworks used to categorize inventions based on their technical features and functions. These systems help organize patents in databases, making it easier for inventors, researchers, and businesses to find relevant information. The two most common systems are the International Patent Classification (IPC), used globally, and the United States Patent Classification (USPC). By grouping similar inventions together, these systems enhance the efficiency of patent searches, ensuring that new inventions don’t accidentally infringe on existing patents while also fostering innovation by providing clear access to existing knowledge.
