PatBase Express users can now easily limit their searches to a specific country. By default, a worldwide search will be performed. However, users now have the option to limit their search results to a specific country or patent issuing authority (e.g. WIPO) by selecting from the country list. If you select United States, for example, this enables you to search only within US patents, and when you display results, you will only see the US members of the family. This new feature makes it much easier to restrict searches to a particular country of interest, and to view only publications from the country of interest – ideal for freedom-to-operate searches.
