How to inquire about the same patent in American patents

1. Judging from the number of patent citations. Patent citation refers to other patent documents related to the technical content of this patent document stated by the applicant in the specification or confirmed by the examiner during the examination. Innovation contains patent citation information of 17 countries. Generally speaking, the more important a patent is, the more times it is cited. The most cited patent documents in a certain field are probably related to the core technology in this field. On the other hand, if a patent cites fewer other patents, it means that the patented technology is more basic; If a patent cites more other patents, it shows that the patented technology is relatively mature, mainly an improvement on the previous technology.

2. Judging by the number of patent members in the same family. The number of patents in the same subject is an important index to measure the economic value of patents, which can reflect the potential technical market and economic influence scope of an invention. Moreover, patent applicants will only submit patent applications to a country if they have expectations about its market. Therefore, it is helpful to understand the applicant's business strategy and market development direction to analyze which countries the applicant has applied for a patent for invention. By the same token, if a company applies for a large number of patents of the same family for a technology, it can also reflect the importance of this technology from one side.

3. Use patent litigation information to make judgments. Patent litigation in the United States usually costs a lot of money and time. If there is no huge conflict of interest behind a patent, enterprises will not rashly carry out patent litigation.
