Appraisal Economics has valued a portfolio of patents and patent applications used to manufacture photovoltaic cells in the solar power industry. The portfolio was transferred as part of a legal settlement between two U.S.-based chemical companies that operate in China. One of the companies had developed a patented process for printing hot melt ink onto the substrate of a silicon wafer to manufacture solar cells. The other company developed similar procedures for manufacturing solar cells. Upon being made aware of the existence of the patented procedure, the second party filed a motion with the Chinese Patent Re-examination Board (CPRB) to invalidate the pre-existing patent. The CPRB rejected the request, upon which an agreement was reached to compensate the first party for patent infringement. The settlement called for valuing the patent portfolio, which was performed by Appraisal Economics.
