A principle rule in copyright law (this applies globally) is that ideas cannot be protected by copyright but the expression of an idea can, because it can be original. Multiple people can come up with the same idea but embodying the same expression of an idea is very rare.
In my industry (and IP is my area of legal expertise), we are well-aware brands like Aldi and Revolution are notorious copycats. Their business models basically entail copying just enough or mimicing the get-up of other brands’ products to get away with selling similar-looking products at a cheaper price in order to target consumers who are looking for cheap dupes. But remember this, the only thing they can get away with copying is the get-up of the brand, not the formulations. I think most of you who have ever purchased Lacura by Aldi, for example, will know exactly what I mean. Even calling it a pale imitation is generous.
