Legal Definitions - related good

A related good is a product that infringes on a trademark because it appears to come from the same source as the marked good, even if it doesn't compete with it. For example, a product called "McKnife" might infringe on the "McDonald's" trademark as a related good.

Another example of a related good could be a clothing line called "Adidas Sportswear" that uses a similar logo and design as the well-known "Adidas" brand, even though they don't sell the same type of products.

These examples illustrate how a related good can cause confusion for consumers who may think they are purchasing a product from a well-known brand, when in reality it is a different company using a similar name or design. This can harm the reputation and sales of the original brand, which is why trademark infringement laws protect against related goods.
