PSA Peugeot Citroën is France’s Leading Patent Filer for the Fifth Straight Year, with 1,237 Patent Applications Published in 2011

The ranking issued today by France’s National Intellectual Property Institute (INPI) has confirmed that once again PSA Peugeot Citroën is the country’s leading patent filer, with 1,237 patent applications published in France in 2011.

These patents, which were filed between July 2009 and June 2010, reflect a dynamic innovation strategy that continues to be assertively deployed across the Group and R&D capabilities that are still deeply rooted in France, to support the move upmarket in the Peugeot and Citroën model ranges.

The new patents are part of a continuous innovation process to develop vehicles that are increasingly environmentally gentle thanks to clean technologies and are safer thanks to onboard electronics and connectivity.

One particular focus was emissions control, ahead of the introduction of Euro 6 standards, and all of the technologies that help to limit carbon emissions. For example, the three-cylinder petrol EB engine launched on the Peugeot 208 is covered by 52 patents pending, of which 17 filed during the development of the cylinder head. This was especially engineered to significantly reduce engine bulk, thereby helping to reduce the Peugeot 208’s weight and to hold carbon emissions to just 99g/km for the 1.0-litre version.

HYbrid4 technology, which made its world debut on the Peugeot 3008, Peugeot 508 RXH and Citroën DS5, is covered by 300 patents pending to guarantee protection of this full-hybrid powertrain, which combines the performance of an HDi diesel engine and the efficiency of electric propulsion.

In the area of safety, the patents filed reflected major strategic innovation programmes to offer increasingly safe vehicles :

  • One example is the AFIL lane departure warning system, which alerts drivers who inadvertently drift across a lane. The system’s latest generation reads the road with a digital camera embedded in the upper windscreen.
  • An innovation offered on the Citroën DS5 automatically switches between high and low beams depending on the surrounding traffic.
  • In the same way, intelligent traction control offers powerful driver support when the weather turns bad.

“Maintaining this level of patent activity in the midst of a recession attests to our commitment to preserving a dynamic industrial property policy. We are particularly committed to strengthening our patent policy on a highly selective basis, in order to enhance the impact of the Group intellectual property title portfolio and consolidate the protection of its strategic technologies. This sustained performance over the past five years also demonstrates the commitment of our 17,000 technicians and engineers to delivering innovative responses to the aspirations of our customers,” said Marc Duval-Destin, Vice President, Research and Advanced Engineering.
