It can be said that this number has nothing to do with you, at least the patent office can't find any information related to you. Even if you call the patent office and find the name of the applicant, you are not sure who the name refers to. In short, there is little effective information.
Then why did the patent office do this?
The answer is: patent authorization is not 100%. Detailed application information, including the applicant's information, will only be made public after patent authorization, but it is confidential before authorization, that is, from acceptance to authorization. The purpose of doing so is actually to consider the interests of the applicant. If the patent is not authorized and then made public, then the technology will be known to too many people, thus losing the market opportunities of some enterprises, which could have continued to protect the patent in the form of trade secrets. Therefore, for these purposes, it is generally impossible to find effective information when the patent receives the notification of acceptance. [Advanced Intellectual Property]
