This is oft repeated but it’s not true. Copyrights do not get revoked if you don’t enforce your exclusivity. Trademarks can be genericised but only in extreme cases (band-aid is NOT genericised for example).
Nintendo is hyper litigious but not for any legal requirement to defend their copyrights.

You can lose trademarks, but this is a copyright issue. You don’t have to defend copyright to keep it.
