Thin and light laptop computers framed the .ultrabook application in ICANN's 2012 New gTLD Program. The string names a product category specification rather than a company or model — an unusual position, since the term was promoted as an industry standard that multiple manufacturers could qualify for while remaining a trademark of the component supplier that defined it.

Category-specification strings raise the closed-generic question in an acute form: the word is meant to be used by an industry, yet owned by one participant in it. The extension is not currently active in the DNS root zone and is not available for registration by any party.
