We investigate how a deferred patent examination system promotes ex-ante screening of patent applications, which reduces both the number of granted patents and the use of economic resources for examinations, without reducing the return from R&D. Based on a real option theory, we develop a model...

Under the Japanese patent system, an applicant has to request examination within a given period of time after application. This paper studies the timing of a request for examination when return on patent is uncertain. When a firm files a patent application, it acquires a timing option limited...
