An infringement search, also known as a clearance search, is conducted mainly for two purposes:
To establish whether a product or process infringes an unexpired patent in the country where it is planned to be commercialized
To verify whether the patent holders can make, use, or market their innovation with no risk of infringing another holder's unexpired patent
Another reason for conducting an infringement search is to underwrite a licensee of a patent. When you get a license to use another's patent to manufacture, use or sell a product, it is vital that the patentee include, in the license agreement, a warranty of non-infringement.
