The Patent Classification System can be a confusing and inaccessible in verbose language. However, the Lens has now enabled exploration based on various patent classification systems; CPC, IPC, and USPC. You can search within the full text of classification definitions and notes to find the appropriate classification code that encompass your query terms. When you are viewing the summary patent document, click on the classification code to lookup the context and full hierarchical description for the code. The quick and easy text search integrates seamlessly with our existing Patent Search and we hope it will make your searches easier.
