What is the value of similar patents?

Through the patent search of the same family, we can know which countries the applicant applied for the patent of the same invention theme. What is the approval and legal status of these patents?

Therefore, enterprises and scientific research institutions engaged in technological innovation should pay special attention to the role of patent family when searching or tracking patent information, whether in the preparation stage of topic selection or in the process of technology research and development. When you stumble across a valuable patent document, you must not neglect the search for its family patent. (2) Patents of the same family can help readers overcome language barriers.
