A more thorough explanation:

Definition: An imitation is an item that closely resembles a trademarked item, to the point where it may deceive people into thinking it is the genuine product.

Example: Let's say a popular brand of sneakers has a unique logo on the side. Another company creates a similar logo and puts it on their own sneakers, which look almost identical to the original brand. This is an example of an imitation.

This is a problem because the original brand has worked hard to build a reputation for their product, and the imitation may trick people into buying a lower quality product. Even if the wholesale buyer can tell the difference, the small retailer or consumer may not be able to, causing harm to the original brand's reputation.
