Question:
Are the 'anonymous' translators the copyright owners or is the WTBTS the copyright owner? And if the WTBTS, then, does the lifetime extension mentioned above apply to a corporation, just as for a real human?
(I think I remember somewhere that the translators presented the copyright to the WTBTS as a gift (of sorts).
(A quick search found this reference (Reasoning Book):
*** rs p. 277 par. 1 New World Translation ***
When presenting as a gift the publishing rights to their translation, the New World Bible Translation Committee requested that its members remain anonymous. The Watch Tower Bible and Tract Society of Pennsylvania has honored their request. The translators were not seeking prominence for themselves but only to honor the Divine Author of the Holy Scriptures.
