Corman Common Lisp is commercial software. In 2013 Roger Corman, the author, indicated he was considering converting it to open source and in January 2015 he published the source code to the Corman Lisp GitHub repository under the MIT license.
Corman Common Lisp was designed and implemented by Corman Technologies in 1995. Previously they had developed PowerLisp for the Mac, but Corman CL was a complete rewrite for Windows. (PowerLisp is no longer developed or supported). They developed and maintained Corman CL, with new major releases about every 18 months (and minor updates more often) until 2006. The CLOS implementation was originally from Art of the Metaobject Protocol Closette, and then extensively rewritten to add missing Common Lisp features and to improve performance.
In January 2015, with Roger Corman's permission, Corman Common Lisp was copied to GitHub and made open source under the MIT license. All future development of Corman Common Lisp is being done from that location.
