What is the difference between core patent family and extended patent family?
Core Patent Family consists of related patents published in those countries/territories that we have searched independently and monitor for changes. These include United States, Canadian, British, French, German, Spanish, Australian, European and World (PCT) publications. Extended Patent Family consists of related patents published in those countries/territories that have not been searched independently and are not monitored for changes. They are identified by finding equivalents to the ‘core’ patent family members in INPADOC based on priority data and have not been verified for accuracy.
