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):
    Gaetano Francis D'Alelio
    Patent Number:
    US 4026871 B2
    Description:

    Aromatic polyimides with phenolic end groups are chain-extended (molecular weight increased) by reacting them with formaldehyde, compounds capable of generating formaldehyde under the reaction conditions or hexamethylene tetramine in the presence of a catalytic amount of lime. These polyimides can be shaped and formed prior to the chain-extending. The aromatic polyimides appropriate for chain-extending are formed by the reaction of aromatic dianhydrides, aromatic diamines and phenolic compoun…

    Patent Number:
    US 4675399 B2
    Description:

    Process for N-acyloxy or sulfooxy 2-azetidinones comprising O-acylation of a .beta.-hydroxy or .beta.-halo hydroxamic acid, and cyclizing the O-acylhydroxamate with TPP-CCl.sub.4 -TEA or with TPP-dialkylazodicarboxylate to the N-acyloxy-2-azetidinone. Solvolysis of the acyl group provides an N-hydroxy-2-azetidinone. e.g., N-Cbz-L-serine is converted to the O-acetyl hydroxamate, cyclized and solvolyzed to N-hydroxy-3-(Cbz-amino)-2-azetidinone. The N-hydroxy-2-azetidinones are useful intermedia…

    Patent Number:
    US 5266468 B2
    Description:

    .beta.-Hydroxy-.alpha.-amino acids are obtained via serine hydroxymethyltransferase catalyzed condensation of aldehydes with glycine. The predominant product with most aldehydes is the L-erythro diastereomer. For example, succinic semialdehyde methylester is condensed with glycine in the process to provide L-erythro .alpha.-amino hydroxy adipic acid mono methyl ester.

    John G. Duman
    Patent Number:
    US 5627051 B2
    Description:

    The present invention is directed to nucleic acid sequences encoding Dendroides canadensis thermal hysteresis proteins. The THPs of Dendroides have significantly greater thermal hysteresis activity than any other known anti-freeze protein. The thermal hysteresis activity of the purified THPs can be further enhanced by combining the THPs with various “activating” compounds.

    Patent Number:
    US 8356475 B2
    Description:

    Described is a method of slowly releasing a catalyst for, inter alia, the purpose of soot oxidation in a particulate filter. An example method includes incorporating an alkali metal oxide in a glass. Slow leaching of the alkali from the glass provides a means to gradually deliver the catalyst over extended periods. Additionally, the example method includes increasing the amount of alkaline metal ions that may be leached from the glass.

    Patent Number:
    US 3562231 B2
    Description:

    The process disclosed herein is the bromination of polymers of propargyl methacrylate and the brominated products produced thereby. Propargyl methacrylate has a terminal acetylenic group which upon bromination gives anethylenic dibromo derivative which is hydrolytically stable. In comparison the derivative obtained upon dibromination of a polymer of allyl methacrylate gives dibromopropyl methacrylate repeating units whereas the dibromonation of propargyl methacrylate gives dibromoallyl methac…

  • Inventor(s):
    Gaetano Francis D'Alelio
    Patent Number:
    US 3890272 B2
    Description:

    Processes for preparing polyimides from bis-maleimides are provided. In these processes, a bis-maleimide is polymerized in the presence of a catalytic amount (usually about 0.01 to 5% by weight of the bis-maleimide) of an alkali metal salt of a Bronsted acid. Preferably, the polymerization is also conducted in the presence of a small amount (usually 0.01 to 5% by weight of the bis-maleimide) of an activator for the catalyst. The activator is an aprotic organic compound having a dielectric con…
