ISO 14443 B Patents


Since 1992, a major program of Research & Development has resulted in Innovatron extending the application of the smartcard technology, enabling its use through a contactless communication interface.

During this program, Innovatron developed a technology, the subject of many patent applications protecting the investments made. A number of these patents relate to the communication interface which is the subject of the standard ISO 14443.

Innovatron favors a wide deployment of this technology and offers licenses under the relevant patents and patent applications to manufacturers of components, portable objects and terminals, on a non-discriminatory basis.

Note that a license is not necessary when using licensed chips or readers.

The patents and patents applications accessible under license are the following:

Project Patent Summary App. Number App. Date Priority
Remote Powering-Modulation Remote powering with transmission of data by modulation of the energy transmitted from the terminal to the portable object, the modulation depth being < 50% PCT/FR97/02229 8/12/1997 FR 96.15163
Anti-Collision
Random reply from the portable objects, at least in the event of collision, with a probability which is a function of a parameter transmitted from the terminal
PCT/FR98/00132 26/1/1998 FR 97.02501
Anti-Collision Hybride-Historique Random reply from the portable objects, at least in the event of collision, with a probability which varies as a function of the history of replies from the portable object PCT/FR99/00079 15/1/1999 FR 98 00383
