Abstract
To make a standard, the protection of the patent rights and the convenience of the standard users must be balanced. In order to solve the problem of the standardization and the intellectual property, a patent policy is established in most International Standardization Organization. ISO IEC and ITU just began to harmonize of this patent policy. The member countries want to prevent the holdup problems so they demanded strongly for them to start this activity. However, is the patent policy effective in the prevention of the holdup problems? Is it possible to find all patents and prevent holdup problems when operating the patent policy strictly? In this paper, I reviewed about the effectiveness of the patent policy from such a viewpoint. As a result, I pointed out that the substantial value of the patent policy is a deterrent effect to someone who has possibility to occur the holdup.
