Thanks to Brian E. Hanlon, Assistant Commissioner for Patents at the USPTO, I learned a new word today:
antepenultimate.
Assistant Commissioner Hanlon recently published a memo dated October 24, 2025 entitled Advance notice of change to the MPEP with respect to false assertions or certifications of entity status. It contains these words:
The ante-penultimate and penultimate paragraphs in MPEP § 410 are revised to read …
Of course we all already knew what “penultimate” means, namely “second from the end”. Thanks to Mr. Hanlon, today I learned of the existence of “antepenultimate” which means “third from the end”. (The word is not actually hyphenated.)
It turns out that there are more words like this:
-
-
- “preantepenultimate” means “fourth from the end” and
- “propreantepenultimate” means “fifth from the end”.
