June 19, 2006 – FormFactor Inc., Livermore, CA, says the South Korean Patent Court has upheld the validity of its patent relating to MEMS-based wafer probe cards. The patent has been disputed by domestic firm Phicom Corp. Following normal practice, the bases for the ruling were not given in detail, and a written opinion will be expected in a few weeks.
Igor Khandros, FormFactor CEO, acknowledged that the ruling likely would not have any immediate business impact, but it does show the strength of the company’s wafer-test patent portfolio.
Earlier this year the Korean Patent Court reopened the case regarding the single patent, but invalidated 10 claims of the patent. The two firms have been in litigation since early 2004, when Phicom’s challenges to three disputed patents were dismissed.
