I think there's mismatch here between you and the parent in that, yes the "VELCRO" trademark is genericised in public use but _officially_ the trademarks are still registered and valid so in law they are not [yet] genericised.

In the UK I can go in to shops the length of the country and ask for velcro and get "hook and eye" or "fabric fastener", is a completely generic term now, just no one wants to fight it in court.
