An INPADOC patent family is defined as comprising all the documents sharing directly or indirectly (e.g. via a third document) at least one priority. This includes all the patent documents resulting from a patent application submitted as a first filing with a patent office and from the same patent application filed within the priority year with a patent office in any other country. In Espacenet these can be found by selecting INPADOC patent family from the left-hand sidebar in the bibliographic data view.
