Don’t know why you were downvoted. Xerox parc did in fact release nothing to the general public iirc. But they got great tech which got ripped off, unlike magic leap maybe ?
Right, just because you haven't bothered to look it up, it doesn't exist. Here are just the Xerox PARC work that was commercialized by Xerox I can think of off the top of my head: Ethernet, XNS, Interpress, the Star and D-series workstations, Mesa, Smalltalk, Cedar.
I was under the idea they never really wanted to release a product for mass consumption.
