Notre Dame Patents

Collection Details Full Record

Description

This collection brings together all of the patents assigned to the University of Notre Dame from 1952 to the present, plus other selected patents prior to 1952. Each record includes a full-text searchable and accessible PDF document for the corresponding invention. The record also includes the present-day academic department with which the inventor was or would have been associated.

Why patents? According to the University’s IDEA Center, “Part of the University’s public service mission is to ensure that the results of its research are made available for public use and benefit. This is accomplished in many ways: through educating students, publishing results of research, and ensuring that inventions are developed into useful products and services for the benefit of the public.”

“Today, our research universities play an even more vital role in creating a better future—not only by educating close to 600,000 graduate students in science and engineering every year, but also, and critically, by performing more than 15% of U.S. R&D in 2011—and according to 2012 NSF data, accounted for the majority (53%) of national basic research. This research, some basic, some applied or ‘translational’ creates new technologies, new products and services, medicines, diagnostics — the list is long and impressive — but also, this research gives rise to entire new industries.” (David Winwood, “The Importance of Patents and Academic Technology Transfer,” March 26, 2015)

The collection also includes the most famous patent associated with Notre Dame, U.S. patent 1,811,959 from 1931, “Vinyl derivatives of acetylene and method of preparing the same” — in other words, synthetic rubber. Invented by Rev. Fr. Julius Nieuwland, CSC, and assigned to DuPont, this patent did, in fact, give rise to entire new industries. More about this invention may be found at the National Inventors Hall of Fame.

These patents are one more example of the University fulfilling Rev. Fr. Sorin’s vision of becoming a “powerful force for good.”

  • Inventor(s):
    Hsueh-Chia Chang, David T. Leighton
    Patent Number:
    US 6428754 B2
    Description:

    An exhaust gas treatment system and method for treating the exhaust gas of an internal combustion engine includes a catalytic converter and a catalytic preheater or igniter upstream of the catalytic converter. A bypass passage extends around the igniter such that during the ignition period about two-thirds of the exhaust gas is bypassed around the igniter and one-third passes through the igniter. The igniter raises the temperature of the exhaust gases passing therethrough to an adiabatic temp…

  • Inventor(s):
    Hsueh-Chia Chang, Shau-Chun Paul Wang, Dmitri Lastochkin, Leslie Yeo, Zachary Gagnon
    Patent Number:
    US 8267914 B1
    Description:

    The present invention provides an electrospray device using a high frequency alternating current (AC) above 10 kHz to generate fine micron sized drops. The apparatus generally functions by applying a high frequency alternating current electric field across one or more micro-needles and one or more conducting elements. The present invention may be used to generate aerosol drops for respiratory drug delivery or as a microencapsulation technique for the encapsulation of drugs, DNA, protein, oste…

    Patent Number:
    US 7960180 B2
    Description:

    Methods and apparatus to capture and release microbe particles using amino-functionalized silica substrates are described. An example apparatus adapted to capture a microbe particle includes a silica substrate and a positively charged material to at least partially coat the silica substrate. The positive charged material includes an aminopropyl functional group.

  • Inventor(s):
    Zachary Gagnon, Hsueh-Chia Chang
    Patent Number:
    US 7744738 B2
    Description:

    The present invention provides a method and apparatus for use in rapid particle transportation, separation, focusing, characterization, and release. Dielectrophoresis and electro-osmotic driven fluid convection are used independently or in tandem as the driving forces for particle manipulation and on occasion characterization. Although dielectrophoresis has been acknowledged for decades as a powerful technique for particle manipulation and characterization, long processing times and measureme…
