Core Viewpoint - Unauthorized sales on Pinduoduo lead to brand price system chaos and decreased trust in genuine products, necessitating a comprehensive rights protection strategy that includes platform compliance reporting, administrative intervention, and professional assistance to safeguard brand interests and market order [1]. Group 1: Pinduoduo Intellectual Property Platform - Complaining through Pinduoduo's official intellectual property protection platform is a direct method to combat unauthorized sales, which can result in penalties such as link deletion and product removal [3]. - The complaint process involves three steps: account registration, qualification submission, and evidence-based complaint [3]. - Registration requires uploading valid proof of the complainant's identity, such as ID for individuals or business licenses for companies, ensuring the authenticity of the complaint [4]. Group 2: Administrative Intervention - Brands can enhance their rights protection by leveraging administrative power through three main methods: 1. Submitting reports to the industrial and commercial department, detailing the unauthorized seller's violations and requesting investigations or penalties [7]. 2. Seeking mediation support from consumer associations to facilitate communication and resolution between brands and unauthorized sellers [8]. 3. Applying for arbitration if there was a prior partnership with the unauthorized seller and an arbitration agreement exists, requiring clear requests and supporting evidence [9]. Group 3: Third-Party Assistance - Small and medium-sized enterprises lacking professional rights protection teams can engage third-party organizations to address unauthorized sales issues, which typically have established pricing control teams and service systems [10]. - These organizations can conduct brand diagnostics and data analysis to identify sellers needing control, creating black and white lists, and developing targeted solutions to efficiently manage unauthorized activities [10]. - Utilizing third-party resources allows brands to save on manpower and time, focusing on product development and market operations while ensuring the selected institution aligns with their needs [10].
