In any brand-driven transaction, trademark due diligence is critical to identify issues or risks that may materially affect the value of the trademark assets. Issues identified by due diligence sometimes can be resolved quickly before finalizing the transaction, for example, filing releases of outstanding security interests to correct the chain-of-title records in the USPTO. However, a serious issue can result in a prospective buyer deciding to reduce the purchase price or abandon the transaction altogether. Although the scope of trademark due diligence varies depending on the particular transaction, key considerations include evaluating: (1) The ownership, scope, validity and enforceability of the trademarks; (2) The risk of infringement or other legal challenge posed by use or registration of the trademarks; and (3) The ability to expand use and registration of the trademarks.
