As of Jan. 1, 2013, the Swiss Patent Office will classify patents using the CPC. This might be the first office (except for the EPO and USPTO) to officially adopt the CPC as its national classification.
I'm the librarian for research services in the Engineering and Science Library at Queen's University in Kingston, Ontario. I've been working with patent information since 1991, including seven years at the U.S. Patent and Trademark Office. I believe that the dissemination of patent information is a public good and should be promoted, especially in the education of science and engineering students.
