Scope of business
According to the purpose of retrieval, it is usually divided into novelty search, project search, case filing search and legal status retrieval. Because of the different purposes, the retrieval methods and database focus are also different.
Patent retrieval is also one of the main means of patent early warning. However, the retrieval is only a means. The core meaning of patent retrieval is "comparative analysis" based on the retrieved data. Only comparative analysis can achieve the purpose of patent retrieval. The purpose of searching the independent patent right is to evaluate the stability of the independent patent right, so as to avoid being passive in the litigation process. Generally, it is a search conducted before applying for a patent in order to evaluate the prospect of authorization. At the same time, it can also help patentees draft patent documents, make trade-offs between claims, and improve the application scheme. Another important significance of novelty retrieval is to save time and economic cost for applicants.
It is a patent search to determine the authenticity and legal status of a patent, so as to evaluate the next step.
