| The development of the knowledge economy and the rising of the digital network have diversified the knowledge innovation and transmission increasingly. The technical innovation is increasingly taking on heterogeneity in different industries and departments. Furthermore, the creation and transmission of literature, art and science have diversified and the trademark shows a binary distinction on using on line or not. These have changed the ecological environment of the intellectual property system. The immense change of its ecological environment further exposes the congenital defects of the intellectual property system and makes it confront with unprecedented crises. The balances between copyright protection and copyright limitation and between promoting creation and promoting dissemination in traditional copyright system have been broken. The patent system has nearly been broken because of poor quality or questionable patent, patent thicket, difficulties in the commercialization of the patented products and public health crisis caused by patenting of increasingly intensive and heterogeneous technology. And there are some negative effects brought about by the trademark expansion. Therefore, people not only reform the current intellectual property system through improving patent system, perfecting copyright system and limiting the expansion of trademark, but also begin to practice and probe the alternative or supplementary mode for the intellectual property system, such as innovation award fund system, patent purchase system, none-exclusive patent system, public conservancy, open access, etc.Because of the diversity, substitutability and environmental adaptability of innovation incentive system, only a diverse system can realize an optimal incentive on knowledge innovation and dissemination in the heterogeneous intellectual domains and realize the balance between knowledge innovation and dissemination. The diverse mode is the evitable choice of the intellectual property system in the future. |
