Its purpose is to collect and document patent families ➢ A new family member must share at least one priority document with at least one other patent in the family. Therefore, a document’s INPADOC patent family means that it is an extended patent family ➢ To reduce the re-classifying of older records, EPO worked on older documents without proper priority data, associating them using inventor and subject matter information to create artificial patent families ➢ Due to their extensive family building rules INPADOC families can become quite large, chemical and biological subject fields tend to generate largest INPADOC families 3 | © Ingenious e-Brain Solution 2019.
