A more thorough explanation:

Definition: A clear-to-use search, also known as an infringement search, is a type of patent search that aims to determine whether a product or method infringes on any existing patents. This search is typically limited to the geographic region where the patent is in force.

Examples: If a company wants to introduce a new product into the market, they may conduct a clear-to-use search to ensure that their product does not infringe on any existing patents. For example, if a company wants to create a new type of smartphone, they would conduct a clear-to-use search to ensure that their design does not infringe on any existing smartphone patents.

Explanation: The examples illustrate how a clear-to-use search can be used to avoid patent infringement. By conducting this type of search, companies can ensure that their products or methods do not infringe on any existing patents, which can help them avoid costly legal battles and potential damages.
