There are many ways for a licensing agreement to significantly boost your business, including: a company may choose to license its trademark(s) if it believes there is a strong acceptance of brand extensions or products. For example, when Apple launched the iPod, there was an immediate need for accessories such as headphones, charging and syncing stations, and carrying bags. Apple has decided not to manufacture these products and to have the products manufactured by a licensee. Apple could thus offer “Earbud Headphones” related to the brand, “iPod Docking Stations” and “iPod Socks”. Each is manufactured by a separate company, but offers the consumer an elegant solution. All these accessories are sold by licensees. Licensors who have neither the desire nor the ability to identify, request and negotiate with potential licensees (let alone manage a program) may wish to enter into a contract with a single licensing agent or licensing agency for multiple people. For example, film companies sell licenses to manufacturers, namely licensees, who make clothes, accessories, toys and electronics on them with the effigy of the characters in their film. Sports teams also sell licenses to companies that manufacture different types of products containing their team logos.
It depends on the type of product category and the brand that is licensed.  You can also use the services of IP lawyers who are experts in the specificity of IP law. . . .
