Abstract
The patents were searched to investigate the trend and the direction of technologies about the recycling of WEEE (waste electric and electronic equipment). Database was collected from WIPS site, and then 223 patents were selected by investigating abstracts. The patents from 1986 to 2007 were analyzed according to countries, international patent classification (IPC), companies, technologies, and recycling-target materials. The most patents were applied in Japan and by Japan companies. Patents about physical pretreatment technology are the most among the patents of the WEEE recycling technologies. Patents about printed circuit boards among target materials are the most because of its high value-added.
