Difference between Klingon and Tengwar

[Mark E. Shoulson]

So, pursuant to Ken Whistler's advice from back in 
https://unicode.org/mail-arch/unicode-ml/y2016-m11/0091.html, I 
submitted a request 
(https://www.unicode.org/L2/L2021/21155-klingon-req.pdf) to have motion 
87-M3 rescinded, thereby making it permissible at least to discuss 
Klingon on its merits.

Although a formal response is yet to be recorded, I have been informed 
that Unicode is declining to rescind its decision, absent some sort of 
consent from Paramount, etc.  And so I ask again: can someone please 
tell me what the difference is between Klingon and tengwar (or Cirth, 
etc) that one has this extra hoop to jump through (getting the decision 
rescinded) and one doesn't?  As far as I know, tengwar is in the same 
situation as regards intellectual property.  If I know how they're 
different, maybe I can see about getting Klingon into line with it so 
they'll be in the same situation.  Can anyone help me find out what the 
difference is?
