Wrong and misleading figures
Some persons state that independent inventors
count very little today in the inventive activity of
their countries. They say that corporations file
90 to 95 per cent of local patents.
IFIA contests these figures.

IFIA wrote to several government Patent Offices
and requested the following statistics: What was the number of patents filed by independent inventors
who are
Residents, compared to the total number
of patents filed by
Residents.  These official
statistics speak for themselves.


Western European Countries

Following an inquiry sent to several Patent Offices in 2005, IFIA received statistics
revealing a relatively high percentage of patents filed by independent inventors:

A recent inquiry conducted by the Brazilian patent office (INPI) on the basis of
statistics for the past 10 years, concerning patents, utility models and industrial designs,
reveals that 66 % of applications by Residents come from independent inventors.
