1) The patent barrier formed by "Patent Bush" needs to be eliminated through the patent pool.
The complexity of modern science and technology can't be compared with before. The patents involved in a product are becoming more and more intensive, and the so-called "patent jungle" phenomenon has appeared. The "patent jungle" greatly increases the risk of obstacles among many patents, prompting patentees to form a patent pool to ensure the smooth implementation of patents.
2) The division of labor is fine, and the industrial chain is constantly elongated, creating a patent pool.
With the division of labor becoming finer and finer, the industrial chain continues to extend, and the number of manufacturers gathered in an industry is far more than in the past, and the technical relevance of upstream and downstream enterprises is getting higher and higher. In this case, if there is no patent pool, the transaction cost of many enterprises seeking patent license will be very amazing, and the one-stop packaging license method of patent pool is undoubtedly the most efficient choice.
3) The standardization of industrial technology gave birth to the patent pool.
Under the background of global integration, influenced by the network effect of technical standards, the role and status of industrial technical standards have become increasingly prominent in recent years. The competition of technical standards has become the commanding height of world industrial competition. Modern industrial technical standards are often combined with patents, and the formation process of technical standards is also accompanied by the formation process of patent pool. Once the technical standard is established, the licensing of a large number of patents contained in the standard may become complicated and become a stumbling block to the promotion of the standard. At this point, the best way to solve this problem is to form a patent pool with relevant patentees. Whether it is MPEG-2, DVD or 3G, patent pool has become an indispensable part of standard implementation.
4) The shortening of modern technology cycle has accelerated the formation of patent pool.
The development of modern science and technology has advanced by leaps and bounds, and the upgrading of technology has accelerated. If a technology can't be industrialized quickly, it will soon become a thing of the past, not only unprofitable, but also unable to recover the research and development costs. However, the process of technology industrialization is often tired by the time-consuming and laborious patent authorization process, and people have to use the patent pool to solve this problem quickly. For example, the DVD-3C Alliance was first established because Philips, Sony and Pioneer couldn't wait for the long patent negotiations and were worried about missing the development opportunities of the DVD industry.
