1. Patent quality: Patent quality is an important factor of patent citation rate. Although Huawei is one of the companies with the largest number of patent applications in the world, the patent quality is not necessarily the highest.
2. Industry field: Most patents related to Huawei are concentrated in the field of telecommunications and network communication, but this field is relatively closed and there are few opportunities for patent cross-reference; In contrast, in areas with more open technologies, such as computer technology and artificial intelligence, there are more opportunities for patent cross-reference.
3. Authorization strategy: Huawei's authorization strategy may also have an impact on its patent citation rate. For a long time, Huawei has hardly used its patent application to sue other companies, but prefers to use patents to obtain authorized income; This strategy can help Huawei ensure a good cooperative relationship with other companies, but it may also lead to a low patent citation rate.
