Siemens Healthcare Diagnostics Assigned Patent

ALEXANDRIA, Va., Sept. 1 -- Siemens Healthcare Diagnostics, Tarrytown, N.Y., has been assigned a patent (8,252,605) developed by Roland Janzen, Landenberg, Pa., and Carsten Ulrich Schelp, Hockessin, Del., for a "method and composition for stabilizing liquid reagents."The abstract of the patent published by the U.S. Patent and Trademark Office states: "The invention relates to methods and compositions for removing a dissociated species from a fluid medium solution during and after it has detached from a solid-phase immersed in said medium, thereby allowing the concentration of free species to remain close to zero, and for improving the signal to noise ratio in assays. This is achieved by employing a substrate, such as a scavenging solid-phase, having an attached binding partner or partners ("scavenger") for the specifically binding species and which is present during storage. This substrate may also contain regions for binding signal generating components attached to the solid-phase. This substrate binds any free species bleeding off the solid phase, increasing the reliability and sensitivity of assays. A subset of the substrates in the invention additionally forms cross-linked networks of solid-phase particles that further increase the sensitivity of assays."

The patent application was filed on April 28, 2009 (12/431,575). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8,252,605.PN.&OS=PN/8,252,605&RS=PN/8,252,605

Ford legal representative, Wilmington, Del.The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method for preparing stretchable bonded nonwoven fabrics which involves forming a substantially nonbonded nonwoven web of multiple-component continuous filaments or staple fibers which are capable of developing three-dimensional spiral crimp, activating the spiral crimp by heating substantially nonbonded web under free shrinkage conditions during which the nonwoven remains substantially nonbonded, followed by bonding the crimped nonwoven web using an array of discrete mechanical, chemical, or thermal bonds. Nonwoven fabrics prepared according to the method of the current invention have an improved combination of stretch-recovery properties, textile hand and drape compared to multiple-component nonwoven fabrics known in the art."

The patent application was filed on March 1, 2006 (11/364,912). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8,252,706.PN.&OS=PN/8,252,706&RS=PN/8,252,706
