Can Several Years of Patent Annuities Be Paid in Advance?

Answer:

Under SIPO’s payment rules described in the article, at most two years of annuities can be remitted on one day. Payment for more than two years must therefore be split.

For example, four years may be paid by remitting two years’ annuities on one day and the other two years’ annuities the next day. This permits payment for several years within a short period.
