Yes, it certainly does. Conducting a Full Clearance Search before a Trade Mark Application is filed increases the value of your brand significantly because you can provide assurances to prospective purchasers and investors that you have secured exclusive legal rights in the name by undertaking a comprehensive and thorough due diligence exercise.
You can also provide assurances that no third parties can challenge your registration on the basis of earlier registered rights, which makes the brand more attractive to licensees, distributors and franchisees and they can be certain that selling goods or providing services under your Trade Mark will not any create exposure to a potential Trade Mark infringement claim against them. The additional confidence you create in your brand increases its value.
