2. Submit a complaint: If the occupier cannot be contacted or negotiation fails, you can consider submitting a complaint to the relevant department and ask the platform management to handle it. For example, you can submit a complaint to Alibaba's intellectual property protection platform, explain your occupation and provide relevant evidence. The platform management will review and handle complaints to protect your intellectual property rights.
3. Seek legal aid: If the occupier infringes on your intellectual property rights, you can consider seeking legal aid to solve the dispute through legal means. You can consult a lawyer to understand the relevant laws and regulations and ways to safeguard your rights and interests.
