It seems that “elisp” is not a good name for Emacs Lisp. When asked, RMS said:
From: RichardStallman Subject: Re: elisp test case question To: guile-devel and other people Date: Sat, 9 Mar 2002 03:48:14 -0700 (MST) "Elisp" was a trademark in the 80s, for CCA Emacs. I am pretty sure it is long dead. But we can ask a lawyer to check. Eben, can you please check?
I looked in the official online database of the US trademarks office ( http://www.uspto.gov/ ) and received no results for “elisp”, I personally think it requires less energy than emacslisp. Writing it e-lisp or e.lisp or e/lisp would emphasise that it is an abbreviation. Zeth

"Elisp" is not presently a registered trademark in the US for any software-related line of commerce. A company called Elispot had marks for laboratory sensing and measurement equipment consisting of the word "Elisp" without graphic, but those marks appear to have been abandoned at the end of 2000. There is no current record of an "Elisp" mark related to any version of Emacs.
Elisp seems fine. You aren’t trying to sell a product and, as mentioned above by Zeth and Eben’s post, there is no trademark registered in the USA for elisp. Even if there were, I highly doubt that informal conversation and notes on a web site (this one) would be enough to be considered infringing use. Then again, IANAL but Eben is. – MattPerry
