A more thorough explanation:

Abandonment of a trademark occurs when the owner of the trademark deliberately stops using the trademark for three or more years, with no intention of using it again in the future. This means that the trademark owner can no longer claim rights to the trademark. As a result, anyone else can use it without any legal consequences from the original trademark owner.

Example 1: A company that used to sell a particular product under a specific brand name decides to stop selling that product and does not use the brand name for three or more years. This is considered abandonment of the trademark.

Example 2: A musician who used to perform under a certain stage name decides to retire and does not use that name for three or more years. This is also considered abandonment of the trademark.

These examples illustrate how abandonment of a trademark can occur in different contexts. In both cases, the trademark owner deliberately stops using the trademark for an extended period, indicating that they have no intention of using it again in the future. As a result, the trademark becomes available for others to use without any legal consequences.
