Why we recommend using patent classifications in comprehensive searches

Patent classifications are primarily used to classify and search for patent documents according to the technical fields that they are related to. Patent classifications are very useful when it comes to investigating the state of the art in given fields of technology. They are applied to patent documents worldwide and are available to search for in most databases, including PatBase.

Using patent classifications when performing searches provides more complete results than text searching alone. It is also worth noting that classifications are independent of the language of the text and any changes in terminology allowing you to perform a much more complete search than using only keyword searching.

You can easily search for relevant patent classifications to your search query within PatBase by using the Classification Finder and Classification Explorer tools. Alternatively, you can use the Optimise tool to refine your search results generated by your search query by patent classification codes and view more relevant patent families and documents.
