INPI started work in the area of patent rankings in 2002 with the creation of its observatory the observatory of intellectual property which resulted in the production of a series of main patent applicants’ ranking report each year.
These main patent applicants’ ranking reports issue the limits of interpretations of such rankings.
The beginning of the year is a time when different patent offices or organizations publish their rank of patent applicants. This study outlines and comments recent rankings of main patent offices’ patent rankings (French, American, European, PCT). This study also highlights methodologies used in these rankings which drive the results; and focus on the French case to stress the trend over time of French patent applicants’ ranking and limits of their interpretations.
