Quoted from MythMaker:... If it is an exact match, patent licensing would come into play as well.
Doubtful any patent licensing would come into play (and agree with your "exact match").
TL;DR: Someone make this. There is no IP (at least in this patent shared earlier)
I've skimmed over the patent. It's kind of interesting...
Couple of interesting points...
1) George G. isn't an inventor! The inventors are DeMar; Lawrence E. (Winnetka, IL), Koziarz; Louis N. (Buffalo Grove, IL), Piotrowski; Peter J. (Long Grove, IL), Weyna; Mark A. (Des Plaines, IL)
2) The patent describes the reflective glass but it is not included in a claim, so there is no IP
In the description (not the claims!): "Cooperatively, a portion 54 of the transparent panel 40 which is aligned with the image surface or screen 52 of the CRT 50 thereabove is constructed of material that has both transparent and reflective properties".
3) The "partially reflective member" does show up in claims, but only in compound claims. Meaning they are saying they own the IP to a pinball machine that uses X, Y and Z where Z is a "partially reflective member". They are not, however, saying they own the IP to the separate creation or use of a "partially reflective member" [I'm sure someone can nit-pick what I wrote here, but the gist is correct... and I didn't want to write multiple paragraphs]
4) it's interesting that in addition to glass with a reflective element, they have protected the use of a "reflective member based on a retractable shade"
