FOCUST is a subscription-based patent search and analysis system created by Wisdomain, and the system includes patent search, analysis, report generation, and patent management functions.[1] FOCUST offers full-text search for US, EP, JP, and CN patent documents, and other available information includes patent legal status, patent ownership status, and citation information.[2]

The Wisdomain website seems to identify three different versions of FOCUST data coverage: the basic FOCUST, FOCUST (US) for US patent data coverage, and FOCUST-J for Japanese patent data coverage.[1] It is unclear whether all of these versions of FOCUST are included in one subscription package, or if the user needs to subscribe to each version separately.

The tables below from the Wisdomain website illustrate the data coverage for independent processed data, patents in English, patents in Korean, and patents in Japanese:[2]
