Object Technology Licensing actually isn't NeXT (NeXT is apparently still maintained as a wholly owned subsidiary of Apple, and owns its own patents).
Object Technology Licensing is the IP holding company that came out of Taligent (a Apple/IBM joint venture in the early '90s to build a new OS). When Taligent folded, IBM got the rights to the code, and Apple got the rights to the patents, now held by OTL Corp.
