Phalanx Biotech, Wisconsin Alumni Research Foundation

Phalanx Biotech of Taipei, Taiwan, and the Industrial Technology Research Institute of Hsinchu, Taiwan, have received US Patent No. 7,182,423, “Leakage detection apparatus and method for multi-channel inkjet cartridge.” The patent claims a leakage detection apparatus and method for a multi-channel inkjet cartridge where the leakage detection apparatus includes a plurality of electrodes and a controller. Each of the electrodes is disposed in one of channels of the inkjet cartridge, respectively, and contacts a reagent in the corresponding channel. The controller is coupled to the electrodes, and then can detect leakage between channels if present.

Wisconsin Alumni Research Foundation of Madison has received US Patent No. 7,183,406, “Method for the synthesis of DNA sequences.” The patent claims a method for the direct synthesis of double-stranded DNA molecules of a variety of sizes and with any desired sequence. The DNA molecule to be synthesized is first broken up into smaller overlapping DNA segments. A maskless microarray synthesizer is then used to make a DNA microarray on a substrate in which each element or feature of the array is populated by DNA of a one of the overlapping DNA segments. Next, the DNA segments are released from the substrate and held under conditions favoring DNA hybridization, under which conditions the segments will spontaneously hybridize together to form the desired DNA construct. The patent’s abstract states that the method makes possible the remote assembly of DNA sequence, through a process analogous to facsimile transmission of documents, since the information on DNA to be made can be transmitted remotely to an instrument which can then synthesize any needed DNA sequence from the information.
