This depends on the situation:
1. You can determine without any doubt how to modify it, for example, "image encoding" is mistakenly typed as "image encoding"
In this case, it doesn’t matter whether you make corrections or not, because the examiner may send you a notice asking you to modify it, or the examiner may directly modify it on your behalf;
2. You cannot determine how to modify it meaninglessly, for example, the unit "nm" "Mistakenly typed as "mm"
In this case, correction can easily lead to over-range. If the correction is made, it must be meaninglessly determined from other parts of the application document that it is nm and not mm. If it can be proved You can make corrections or make modifications when replying to the notice; however, if it cannot be proven that the modifications do not exceed the scope, the corrections will cause the modifications to exceed the scope. In this case, the suggestions are as follows:
2.1 If the application is still If it has not been published, it is recommended to re-apply for a new patent and immediately revoke the current patent application
2.2 If the application has been published, there is no better way to deal with it. At this time, try to find some documents that have proven that it is true. It is to mistype "nm" as "mm" (it is better to have the same wording as the current patent application) to convince the examiner that the amendment does not exceed the scope.
To summarize: if it does not exceed the scope, it does not matter whether it is corrected or not; if it exceeds the scope, it does not matter whether it is corrected or not
If it has not been made public:
1.1 Typos cause the claim to be unclear or the scope of protection to be incorrect (i.e. there are substantive issues), and corrections may be made
