Though not the earliest French fountain pen technology, in 1827, French inventor Edme-Nicolas Favreau filed what is likely the second fountain pen patent application in France. The application was filed with the Institut National de la Propriété Industrielle (INPI) on March 23, 1827, and Mr. Favreau’s 5-year patent number 3177 was issued on May 4, 1827.
The patent was for a pen holder that serves as an inkwell and that is placed in a wallet like a pencil. The novel fountain pen design is clearly identified as a piston operated refill mechanism functioning as a fountain pen.
Favreau described his invention as a porte plume et encrier a pompe aspirante / a “pen holder and inkwell with suction pump”. Mr. Favreau further elaborated “to ink the pencil holder using a suction and crushing pump, which he declares to have invented …”
