Patents, software, and skills

École Polytechnique manages and develops its intellectual property portfolio. The role of the research partnerships and intellectual property department (Service Recherche Partenariale et Propriété Intellectuelle - SR2PI) is to develop the portfolio of patents, software and know-how of the École Polytechnique's laboratories.

Each year, once the SR2PI has reviewed the opportunities, École Polytechnique applies for an average of twenty priority patents. Currently, École Polytechnique holds over 140 patent families, either solely or jointly with academic institutions or businesses. Some of these families extend to Europe, the United States, Japan, Korea and China. École Polytechnique has over 400 titles that it maintains throughout the world.


Examples of software registered by École Polytechnique

École Polytechnique makes its patents, software and know-how available to businesses. These technologies, developed at the X's research center, can be used by manufacturers and accessed subject to license terms and conditions.

> XFTA
Industries that develop systems constituting a risk for users and/or the environment are required to carry out risk analyses. Such analyses rely on probabilistic models. Commercial software makes it possible to perform the calculations for this type of model, and in particular which calculate the fault trees.
XFTA software was developed by the researcher Antoine Rauzy in the École Polytechnique's Computer Science laboratory (LIX). The software offers calculation engines for fault trees that use the most powerful algorithms currently available. XFTA can thus quantify relevant trees quickly, and much faster than the commercial tools on the market.
XFTA is also developed as open-source software, enabling it to be widely distributed in the academic world and in major groups.

> OPTOPO
OPTOPO is a software module for shape-optimization, used to change the shape of parts so they are lighter but do not lose solidity. It uses topological and geometric optimization, and has multiple applications in the aeronautical and automobile industries where light parts are a guarantee of savings in consumption.


The last three published patents held by the École Polytechnique

> International application : MICROFLUIDIC PROCESS FOR TREATING AND ANALYSING A SOLUTION CONTAINING A BIOLOGICAL MATERIAL, AND CORRESPONDING MICROFLUIDIC CIRCUIT, published 17 April 2014, Number WO 2014/056930 A1
Abstract : This invention relates to a microfluidic process that processes and analyzes a solution containing a biological material. It includes a stage where the solution is introduced into the microchannels of a microfluidic circuit; a stage where drops of this solution form under the effect of changes to the surface tension of the solution; a stage where the drops are displaced to one or more storage areas under the effect of changes to the surface tension of the drops; a stage where the drops are processed; and a stage where the drops are analyzed.

> International application : MICROFLUIDIC CIRCUIT ALLOWING DROPS OF SEVERAL FLUIDS TO BE BROUGHT INTO CONTACT, AND CORRESPONDING MICROFLUIDIC METHOD, published 17 April 2014, Number WO 2014/056931 A1
Abstract : This invention relates to a microfluidic circuit with defined microchannels capable of containing fluids. It includes at least one device to form drops of a solution and a means of guiding the drops to a storage area in which one of the drops may be brought into contact with a drop of another solution. The walls of the section of the microchannel forming the first drop‑formation device move apart so that drops detach from the first solution under the first solution’s surface-tension forces. The means of guiding these first-solution drops are sections of the wall of the microchannels, which move apart so that the drops move under the first solution’s surface-tension forces.

> International application : METHOD AND DEVICE FOR GENERATING A FOCUSED STRONG-CURRENT CHARGED-PARTICLE BEAM, published 1 May 2014, Number WO 2014/064380 A1
Abstract : Process for generating a focused beam of charged particles. It includes at least the stages of a ) generating a beam of charged particles, b) emitting a laser pulse, c) generating a focusing magnetic field structure in a target, by means of the interaction of the laser pulse with the target, and d) making the beam of charged particles penetrate the focusing magnetic field at least partially.
