⚖️ Genericide – is a process whereby a trademark or brand name loses its distinctive identity and thus, loses its trademark status which is usually against their owner’s intention. This usually happens when the trademark becomes too successful and had become synonymous with a certain product or service.

📑 General thumb of rule is that a very general word or term cannot and should not be trademarked. Or what we commonly known as a generic trademark.
Seems like turning a product or service into a household name is not necessarily a good thing at all.
