Earlier quoted context omitted.
For what it's worth, the initial EJB spec was written by IBM, so I guess the answer to your question could be yes. "The EJB specification was originally developed in 1997 by IBM and later adopted by Sun Microsystems" https://en.wikipedia.org/wiki/Enterprise_JavaBeans
Thank you for the link. I looked up Java EE, which according to wikipedia mostly originated from WebLogic. The founders didn't seem that enterprisey though: http://otechmag.com/magazine/2015/summer/michel-schildmeijer... So IBM does sound likely.
Hints that https://en.wikipedia.org/wiki/CICS was the product inspiring EJB.
