If I want to send a fax to a patent examiner, what number do I use?

Question

If I want to send a fax to a patent examiner, what number do I use?

Answer

The fax number at the USPTO is usually the Examiner’s number but with the digits “273” instead of “272”.  However, not all Examiner’s fax numbers follow that pattern – some change the first digit in the last 4 numbers.  So you should double-check with the Examiner first.
