CAS STNext® Coffee Lecture Monitoring IPC/CPC classifications in CAS STNext

Date & Time

The International Patent Classification (IPC) and Cooperative Patent Classification (CPC) systems are powerful hierarchies that categorize patents into specific technological domains. As new areas of innovation emerge and technologies evolve, these systems are periodically revised to reflect these developments. Therefore, it is critical to keep your search strategies and alerts updated as new classification symbols are introduced or changes are made.

CAS STNext offers powerful features to leverage these classification systems and incorporate them into your search strategies. In this session, we will share best practices on searching the hierarchy of these classification systems, when to use truncation, and more.

What you will learn

  • Best practices for staying up-to-date with changes in IPC/CPC systems. 
  • How to combine IPC/CPC classification with other keywords or claims text search terms.
