09.30 : Hearing C-321/03 Dyson
Approximation of laws
Interpretation of Article 3(3) of Directive 89/104/EEC: First Council Directive of 21 December 1988 to approximate the laws of the Member States relating to trade marks – Mark comprising a functional feature (transparent plastic cylinder) forming part of a hoover [sic]

(Pointed out by IPKat)

At least they didn’t call it a dyson.
I remember a student in a dictation referring to small birds hoovering over the meadows, but further curious usage is touched on in Wiktionary. I don’t think the noun is generic, is it, even if the verb may be?
