Purpose and Objectives

According to its statutes, the Patent Documentation Group's purpose is "to provide for cooperation in information and documentation from and for patents and to exchange knowledge and experience".

Our guiding principles are that “it is only with accurate and reliable patent information that we can make sensible investment decisions and it is only through access to powerful search systems that the necessary patent information can be obtained efficiently”.

Our objectives are to:  

  • debate and discuss new developments in patent information
  • compile opinions and common interests  
  • formulate proposals and suggestions
  • communicate these to third parties in the field of intellectual property
  • deal with current and emerging problems    

The PDG cooperates worldwide with organisations and companies providing products and services related to patent information, in order to e nsure that the quality of the products and services meet the needs of the users. It particularly focuses on accuracy, completeness, reliability, clarity of content and timeliness of delivery. The organisation stimulates both the improvement of existing and the development of new products and services and strives for a fair partnership between the suppliers and the users of such information products and services. 


Regular high-level meetings take place with the European and other national Patent Offices as well as with major database producers and providers. The PDG also enjoys a permanent observer status at the World Intellectual Property Organization (WIPO).


Major Achievements 

Through their dedicated work over the past fifty years, the efforts of PDG companies has led to major improvements in the field of patent information. PDG Working Groups make proposals and put forward ideas for new products and services to information providers. They cooperate closely with the major patent information providers and vendors and assist them in improving the quality, content and the usability of their databases. Many of the most useful commands, search and display features, post processing and statistical analysis tools offered by various hosts are the results of these initiatives. Many of the databases and search facilities such as those for Markush chemical structures, which are now taken for granted, have been developed with the help and involvement of the PDG companies. The Thomson Patent Citation Index database was built following requests from the PDG companies. The most widely used communication software, STN-Express®, was born from a project of an ad hoc PDG Working Group. The PDG companies were also the driving force behind the creation of the best-known legal status database INPADOC. PDG companies played a major role at the EPO Hearing on “Provision of Patent Information to the Public” in 1997 and its availability to commercial providers at cost prices. Subsequently, the EPO offered the database Esp@cenet ® . The PDG members were instrumental in bringing about the standardisation of correction procedures (ST 50) and the availability and implementation of SPC data. More recently, they were active participants in WIPO discussion on the introduction of IPC 8. PDG members monitor, test and compare information systems and services and strive for fair pricing and information use policies. Thereby, the entire user community benefits from their sustained efforts in search of high quality patent information products
