As the global need for patent information increasingly transcends the language and cultural barriers, the complexity of the tools that facilitate the data retrieval and analysis expands beyond the traditional confines of their initial purpose.

This presentation outlines some of the well known, as well as less obvious, uses of the classification in the environment of commercial databases. It also presents some of the challenges the commercial data providers face when dealing with globally sourced classification data and the implementation of major projects like IPC8 and CPC.
