Millipore, U of Rochester, and Corning Recently Awarded US Patents

Premium
Millipore has been awarded US Patent No. 7,135,148, “Access holes for a multiwell filter plate for multiwell test apparatus.”
 
Inventors listed on the patent are Kenneth DeSilets, Donald Rising, and Jeanne Phillips.
 
According to its abstract, the patent protects a multiwell filter plate of a multiwell test apparatus to effect addition or removal of liquid from a feeding tray positioned below the multiwell filter tray. The patent describes access holes extending through a plate of the multiwell filter plate so that a syringe can be extended through the holes.
 
Millipore has also been awarded US Patent No. 7,135,149, “Positioning pins for multiwell test apparatus.”
 
DeSilets and Rising are also the inventors.
 
According to its abstract, the patent protects a multiwell test apparatus comprising a multiwell filter plate and having wells that fit within the wells of a single or multiwell receiver plate. The multiwell filter plate also is provided with posts which fit into holes of the receiver plate. The posts and holes are shaped to fix the position of the wells of the multiwell filter plate within the wells of the receiver plate and to permit controlled lateral movement of the multiwell filter plate when it is partially removed from the receiver plate, so that excess liquid on the wells of the multiwell filter plate can be directed into the wells of the receiver plate.
 
More specifically, both patents ‘148 and ‘149 relate to a multiwell filter plate and multiwell test apparatus suitable for promoting fluid interactions, such as by growing cells in a nutrient medium within the wells. The multiwell filter plate permits adding or removing liquid from the feeding tray of a multiwell test apparatus without disturbing a material such as cells within the wells.
 

 
The University of Rochester has been awarded US Patent No. 7,135,278, “Method of screening for therapeutics for infectious diseases.”
 
Maurice Zauderer is the sole inventor listed on the patent.
 
According to its abstract, the patent protects a method of screening for host cell gene products that are useful as therapeutics for an infective disease. This method comprises identifying genes that are differentially expressed in infected cells, and screening the differentially expressed gene products for immunogenicity, the abstract states.
 

 
Corning has been awarded US Patent No. 7,136,550, “Single-fiber launch/receive system for biosensing applications.”
 
Eric Mozdy is the sole inventor listed on the patent.
 
According to its abstract, the patent protects an interrogation system and method that use a single-fiber launch/receive system for interrogating a biosensor (optical sensor) to detect the occurrence of a bio-chemical interaction (e.g., biological binding of ligands with analytes). The system can also be used can be used to interrogate a biosensor so that a computer or electrical hardware can also determine whether or not a biological substance such as a cell, molecule, protein, drug, chemical compound, nucleic acid, peptide, or carbohydrate is present on a biosensor. In addition, the system can be used to help perform other label or label-free studies such as photoluminescence assays, fluorescence assays, scattering assays, absorbance assays, cell migration assays, drug permeability assays, drug solubility studies, virus detection studies, and protein secretion studies, the patent states.
