We organized tasks on patent information retrieval during the decade from NTCIR-3 to NTCIR-8. All of the tasks were ones that reflected real needs of professional patent searchers and used large numbers of patent documents. This chapter describes the designs of the tasks, the details of the test collections, and the challenges addressed in the research field of patent information retrieval.
