Explain what a generic name is with reference to trademarks

What will be an ideal response?

Once a company has been granted a trademark or service mark, the company usually uses the mark as a brand name to promote its goods or services. The owner of the mark wants to promote its brand so that consumers and users will easily recognize the brand name. However, sometimes a company may be too successful in promoting a mark, and at some point in time, the public begins to use the brand name as a common name to denote the type of product or service being sold rather than as the trademark or service mark of the individual seller. A trademark that becomes a common term for a product line or type of service is called a generic name. Once a trademark becomes a generic name, the term loses its protection under federal trademark law.
