Recent Patents in Bioinformatics, February 2011 — March 2011

US Patent 7,912,650. Information processing system using nucleotide sequence-related information. Inventors: Takamasa Kato, Takeo Morimoto. Assignee: Hitachi.

Describes a system for processing information on nucleotide sequences. Specifically, the patent abstract states that the method will be used to process information for "providing semantic information and/or information associated with the semantic information useful for each individual organism through effective utilization of differences in nucleotide sequence-related information among individual organisms"


US Patent 7,904,250. Computer software to assist in identifying SNPs with microarrays. Inventors: Michael Molla, Todd Richmond, Steven Smith, Thomas Albert. Assignee: Roche Nimblegen.

The patent describes a method to identify SNPs from microarray hybridization data.


US Patent 7,890,445. Model selection for cluster data analysis. Inventors: Asa Ben Hur, Andre Elisseeff, Isabelle Guyon. Assignee: Health Discovery Corporation.

Describes a method for "choosing the number of clusters, or more generally the parameters of a clustering algorithm" that is based on comparing the "similarity between pairs of clustering runs on sub-samples or other perturbations of the data."


US Patent 7,890,313. Method and apparatus for analysis of molecular combination based on computations of shape complementarity using basis expansions. Inventors: David Kita, Somalee Datta, Adityo Prakash, Eniko Fodor. Assignee: Verseon.

The patent abstract describes a method for molecular combinations that feature two or more molecular subsets. According to the investigators, it "computes the shape complementarity of the system utilizing a basis expansion representing molecular shapes of the first and second molecular subsets in a coordinate system."
