These searches collect material (evidence) for the invalidation of patents which may bar the marketing of your product. When necessary, patent documents and technical journals can be tracked down not only in Japan, but in many other countries as well. Fees start at 200,000 yen (about US$2,350), and search periods are generally from 10-30 days.
