Canon has received US Patent No. 7,731,905, "Process for producing probe carrier and apparatus thereof." The patent describes an apparatus that produces a probe carrier by discharging liquids containing probes capable of specifically bonding to a target substance on a carrier. The apparatus includes a liquid discharge device, a positioning device for determining a position between the liquid discharge device and the carrier, an application information detector to detect application information of discharged liquids, and a defective spot detector to detect spots where the liquids are not applied. The apparatus also includes a discharge data-forming device for forming data on the defective spots, a processor for counting a number of redrawings, and a secondary scanning direction driver. Redrawing is performed according to discharge data, and when the number of redrawings exceeds a prescribed number, the system alerts the user, according to the patent.
Grace Bio-Labs of Bend, Ore., has received US Patent No. 7,731,909, "Reaction surface array diagnostic apparatus." The patent claims a reaction surface array that includes a substrate of reaction surfaces, and a plate and a gasket, each with a number of through bores that can be aligned with one of the reaction surfaces to form a fluid-tight well around each reaction surface when the gasket and the plate are affixed to the substrate to form a stack. Clamp members are then used to engage the opposite side edges of the stack to compress the gaskets, and side-by-side disposed clamped stacks of plates, gaskets, and substrates are subsequently mounted in a tray in the standard footprint of a microtiter plate.
Samsung Electronics of Seoul, Korea, has received US Patent No. 7,732,139, "Multiple SNP for diagnosing cardiovascular disease, microarray and kit comprising the same, and method of diagnosing cardiovascular disease using the same." The patent claims a biomarker panel composed of multiple, individual SNPs for the prediction of incidence and susceptibility to cardiovascular disease, as well as sets of polynucleotides, a microarray, and a kit.
Samsung has also received US Patent No. 7,732,191, "Hybridization system using the control of pump and valves in closed system." The patent describes a system for hybridizing a biochip. It includes: a chamber device with a support for a biochip and a cover with a sample inlet; an agitation device that contains two air channels connected to ends of the hybridization chamber; two valves disposed in the air channels; an integrated air channel to which the two air channels are connected; an air pump disposed in the integrated air channel; and a washing and drying device.
Hitachi of Tokyo has received US Patent No. 7,734,422, "Method for evaluating DNA probes position on substrate." The patent describes an oligonucleotide array composed of an array of multiple oligonucleotides with different base sequences fixed onto known and separate positions on a support substrate. According to the patent, the oligos are biological stress-related genes or complementary sequence chains to these genes; and the oligos are classified according to their gene functions, where the fixation region on the support substrate is divided into the classification.
