Differences in the scope of rights required by patent families in different countries

Theoretically, a narrow patent family should claim the same scope of rights in different countries, but in practice, the scope of patent application is the product of a series of bargaining between the country (Patent examiners) and the patentee, so the scope of patent application approved by different countries may be different. In addition, because patent applications involve the use of different languages, such as Chinese in China and English in the United States, there are often many mistakes in language conversion (translation). The determination of patent family is only the first step. Due to the differences in language translation and examination results in different countries, the protection scope of different patents of the same patent family is basically different in different countries. Therefore, it is necessary to further distinguish between detailed patent layout judgment or legal status inspection.
