When using logos or elements that are similar to those of well-known brands in advertising campaigns, you need to be extra careful to avoid trademark infringement and legal disputes. Here are some tips to help you avoid direct trademark infringement charges: 1. **Original Design**: Make sure your logo or visual elements are completely original. This means that the design should be significantly original and visually different from the logo of the well-known brand. 2. **Avoid Confusion**: Make sure consumers will not confuse your logo with the well-known brand. The design should be different in color, graphics and text. 3. **Additional Disclaimer**: When using similar elements, you can ensure that consumers can clearly identify the difference between the advertising subject and the well-known brand by clearly stating your brand identity in the advertisement. 4. **Functional Use**: In some cases, if the use of other people's elements is for the purpose of functional description or comparison of products or services and does not cause confusion, it can be fair use to a certain extent, but this requires legal professional opinion to support it. 5. **Consult Legal Counsel**: Before implementing the advertising plan, consult a trademark attorney or intellectual property expert to ensure there is no potential infringement risk. 6. **Research and Analysis**: Understand how other companies handle similar situations in competition and review relevant legal cases to help you better understand the legal boundaries. Ultimately, when creating designs, you should respect the intellectual property rights of others and establish a unique and strong brand image when promoting them in the market to enhance consumers' awareness and recognition of the brand.
