FENDERS FOR PIER PROTECTION AGAINST VESSEL COLLISION

US 8484787  | Issue Date: July 16, 2013

US 8739343  | Issue Date: June 3, 2014

 George Z. Voyiadjis & Sherif El-Tawil

This set of patents protects pier fenders that provide superior protection to pier structures and barges on waterways. Using a system of modular components, the fender collapses as an impact occurs, minimizing damage to the pier, the bridge that it supports and the barge.

ENRICHMENT OF STEM CELLS FROM ADULT TISSUES

US 8501397  | Issue Date: August 6, 2013

Gary E. Wise & Shaomian Yao

This patent protects a method to isolate adult stem cells from adult tissues. Using this method, adult stem cells can be purified on a large scale without expensive equipment and without the presence of cell surface markers. By using adult stem cells, a transplant patient’s own cells may be used in tissue engineering, lessening the chances of tissue rejection.

TETRAAZAPORPHYRIN-BASED COMPOUNDS AND THEIR USES

US 8524891  | Issue Date: September 3, 2013

Robert P. Hammer, Steven A. Soper, Serhii Pakhomov, Timothy J. Jensen, Michael W. Allen, Irina V. Nesterova & Maria da Graca Henriques Vicente

This patent protects a highly customizable labeling dye that absorbs and emits radiation in nearinfrared wavelengths. This narrow absorption and emission spectrum can create a signal through biological tissue which is useful for bioanalytical and bio-imaging applications. The dye can easily be attached to other molecules and has low toxicity when not exposed to light, making it ideal for photodynamic cancer therapies that treat tumors.

SYSTEM AND ARCHITECTURE FOR ROBUST MANAGEMENT OF RESOURCES IN A WIDE-AREA NETWORK

US 8572290  | Issue Date: October 29, 2013

Supratik Mukhopadhyay & S. Sitharama Iyengar

This patent protects computer architecture that enhances the coordination of data being transmitted between computers on a network. Using this technology computers can reliably access, process and evaluate information acquired from other computers on the same network and adaptively take action based on that information.

SYNTHETIC HERPES SIMPLEX VIRUSES TYPE-1 FOR TREATMENT OF CANCERS

US 8586028  | Issue Date: November 19, 2013

Konstantin G. Kousoulas

This patent protects an engineered herpes simplex virus type-1 that could be used to treat various cancers by directly injecting the altered virus into the tumors. This virus has been shown to replicate and spread in cancer cells without spreading to normal cells.

METHOD FOR DNA DOUBLE-STRAND BREAK REPAIR IN VITRO AND APPLICATIONS THEREOF

US 8586362  | Issue Date: November 19, 2013

Michael M. Cox, John R. Battista, Audrey J. Klingele & Joseph R. Piechura

This patent protects a system to repair DNA double-strand breaks efficiently and in vitro. This technology permits damaged or poor quality DNA samples to be used in forensic testing, DNA extraction from ancient sources, genome sequencing and metagenomics.

ELECTRICAL RESONANCE DETECTION OF PARTICLES AND ANALYTES IN MICROFLUIDIC CHANNELS

US 8587330  | Issue Date: November 19, 2013

Donald A. Patterson

This patent protects a method to quickly and accurately count cells in biological fluid samples by eliminating electrical interference that can make detection difficult. This is critical in tests where complete blood counts are needed to diagnose certain cancers based on the number of healthy and abnormal cells present in a blood sample.

DETECTION OF NUCLEIC ACID SEQUENCE DIFFERENCES USING COUPLED LIGASE DETECTION AND POLYMERASE CHAIN REACTIONS

US 8597890  | Issue Date: December 3, 2013

Francis Barany, Matthew Lubin, George Barany & Robert P. Hammer

US 8597891  | Issue Date: December 3, 2013

Francis Barany, Matthew Lubin, George Barany & Robert P. Hammer

US 8642269 | Issue Date: February 4, 2014

Francis Barany, Matthew Lubin, George Barany, Robert P. Hammer & Phillip Belgrader

This set of patents protects methods for combining two common DNA analysis techniques to detect differences in a DNA sequence. These technologies enable large scale, reliable, cost-effective DNA analysis for forensic testing, diagnosis of genetic diseases and other genetic testing.

SOFT TISSUE FIXATION DEVICE

US 8603115  | Issue Date: December 10, 2013

Mandi J. Lopez & W. Todd Monroe

This patent protects a surgical device that provides superior graft tensioning control during ligament reconstruction. This device, known as the GraftGrab, allows surgeons to customize the ligament tension based on the quality of the graft and then affix it with a single-handed fluid motion. The device has a low profile so it is unnoticeable under the skin and it can be made of bioabsorbable material.

DETECTION OF NUCLEIC ACID SEQUENCE DIFFERENCES USING THE LIGASE DETECTION REACTION WITH ADDRESSABLE ARRAYS

US 8624016  | Issue Date: January 7, 2014

US 8703928  | Issue Date: April 22, 2014

Francis Barany, George Barany, Robert P. Hammer, Maria Kempe, Herman Blok & Monib Zirvi

This set of patents protects an apparatus that combines two common DNA analysis techniques. These technologies enable large scale, reliable, cost-effective DNA analysis for forensic testing, diagnosis of genetic diseases and other genetic testing.

SYSTEM, METHOD, AND COMPUTER PROGRAM PRODUCT FOR DATA MINING APPLICATIONS

US 8725663  | Issue Date: May 13, 2014

Evangelos Triantaphyllou & David Sathiaraj

This patent protects a system that detects, creates and refines groups of related data points to form more accurate and specific data classification and improve data mining. The system examines and identifies data points near a boundary region thereby reducing computation time.

PHOTORESIST-FREE MICROPATTERNING ON POLYMER SURFACES

US 8758974  | Issue Date: June 24, 2014

Steven A. Soper, Robin L. McCarley & Bikas Vaidya

This patent protects a method of creating precise and functional miniaturized patterns on polymer surfaces. These patterns lead to smaller channels in microarrays that can hold a higher number of DNA probes necessary for gene expression profiling.
