You can patent an improvement or tweak to a previous product. E.g., someone could patent a pencil, then someone could patent a pencil with an eraser, then someone could patent a pencil with a pyramid-shaped eraser. So they possibly are trying to patent some small inprovement to the older product.

But having a patent lets you sue your competitors in a very expensive way for them, even if they win by invalidating your patent as straightforwardly as the legal system allows. Funny how that works. I guess when the OP said you need a lawyer, it was more of a threat than friendly advice.
