By Christopher P. Singer --
IpAuctions, Inc. recently announced that it will seek to sell U.S. Patent No. 6,645,525, which relates to drug delivery technology. The patent is titled "Ionically Formulated Biomolecule Microcarriers," and is assigned to Sedum Laboratories, Inc. The technology, called "Bi-Acervation" which can encapsulate, stabilize, and provide sustained release of small molecule drugs, biomolecules (e.g., nucleotides and peptides), and vaccines.
The patent contains fifteen total claims, three of which are independent. The independent claims relate to a microparticle composition, a method for producing microparticles, and a method for delivering a biomolecule to a human or animal. Representative claim 1 recites:
1. A microparticle composition for delivery of a biomolecule comprising a biomolecule incorporated in a complex comprising a cationic polymer ionically complexed with an anionic polymer, wherein the cationic polymer is polyethyleneimine and the anionic polymer is dextran sulfate.
According to the description provided by IpAuctions, the technology combines aqueous biodegradable polymers with an active agent to create micro matrix formulations that are less expensive to produce, more bioactive, and better tolerated than pharmaceuticals formulated with other methods. IpAuctions Inc. will hold an online auction March 13, 2008 thru March 20, 2008. More information can be obtained about this and other patent auctions from IpAuctions by phone at 775-826-1300 or by e-mail at [email protected].
