Patents have restrictions on regions. A patent is valid only
within a specific geographic region, and if a specific patent is
desired to be valid in another region or country, it should be
filed in that region or country using the local official language.
For example, if an American applicant for a patent wants to have
the right of this patent in China, the American applicant needs to
file this patent in Chinese before the China National Intellectual
Property Administration. Similarly, if a Chinese applicant applies
for a patent right in America, the applicant needs to submit an
English text to the USPTO. All these procedures involve
interlingual translation.
Interlingual translation seems easier to Chinese applicants as
their school education covers English language learning and they
are able to understand English patents or English notifications
more or less, and thereby most Chinese applicants can easily find
some obvious technical errors, if any.
