If an inventor wants to protect his invention in a particular foreign country, he must apply for and be granted a patent by that country’s patent office because a patent issued by one country is not enforceable in another country. For example, a US patent is only enforceable in the United States. If the applicant also wishes to obtain patent protection for that invention in Japan, he will have to file for and be granted a patent by the Japanese Patent Office.
Most patent applications filed in US and international countries under the Patent Cooperation Treaty (PCT) are published 18 months after filing, and therefore very often represent the first published information available.

PCT (WIPO): International Patent Application G-Pat: global patent – DE (Germany), GB (Great Britain), FR (France), CH (Switzerland) INPADOC: International Patent Document Center is an international patent collection. The database is produced and maintained by the European Patent Office (EPO). It contains patent families and legal status information, and is updated weekly. INPADOC was founded by the World Intellectual Property Organization (WIPO) and the government of Austria under an agreement on May 2 , 1972 . A little less than twenty years later, on January 1 , 1990 , it was integrated into the European Patent Office. An EPO sub-office was then created in Vienna , Austria. The INPADOC database, which is publicly accessible, provides information about patent families, i.e. corresponding patent applications, i.e., patent applications in different countries which claim the same priority and which normally disclose the same invention. It also provides information concerning the legal status of patent applications and patents in those countries which report status changes.

Let's assume that: You have invented a new tool and want to sell your idea. There are already patent applications for an identical tool. You are therefore not allowed to sell it in countries in which a protection right already exists. You can't apply for a patent either because the invention is no longer new. But you are allowed to put it on the market in other countries where patent rights are not granted. Hence, knowledge about the patent family will be useful - find out if further applications have been made in other countries.
