Group 1 - Beijing Yuanli Technology Co., Ltd. has filed a lawsuit against Zhejiang Alibaba Xianyu Network Technology Co., Ltd. and individual seller Jiang for copyright ownership and infringement disputes [1][2] - The court hearing is scheduled for November 12, 2025, at 9:00 AM at the Xihongqiao First Court in Shanghai [1][2] - The case number is (2025) Hu 0118 Min Chu 21317 [2] Group 2 - Beijing Yuanli Technology Co., Ltd. is an affiliate of the online education company Yuanfudao, operating in the fields of online education and digital content [2] - Xianyu is a second-hand trading platform under Alibaba Group, which has been involved in multiple intellectual property protection cases in recent years [2]

Core Viewpoint - MicroAlgo Inc. has developed a blockchain-based traceable IP rights protection algorithm to address the limitations of existing copyright protection technologies and enhance the safeguarding of intellectual property rights [1]. Group 1: Algorithm Features - The algorithm utilizes blockchain's distributed ledger and immutability to ensure precise traceability and secure protection of IP copyrights throughout their lifecycle, from creation to transaction [2]. - It incorporates a quadratic matrix transformation model that quantifies and encodes critical parameters of IP rights transactions into a structured multidimensional data system, generating a unique and verifiable transaction identifier [3]. - The quadratic transformation creates a bidirectional, verifiable mathematical correlation, allowing for the original transaction data to be reversed for verification while forming a "digital fingerprint" for IP rights tracking [4]. Group 2: Security Mechanisms - A distributed random embedding mechanism embeds key IP identifiers across various blockchain nodes in a concealed and randomized manner, making it difficult to tamper with copyright information [5]. - The positional mapping function design generates mapping factors using parameters like time and transaction hash values, enabling rapid location and end-to-end tracking of copyright data [6]. - The algorithm can swiftly retrieve copyright information during anomalies, ensuring effective protection of intellectual property rights [7]. Group 3: Stability and Traceability - The algorithm maintains stable operation in complex network environments, ensuring accurate tracking and management of copyright information without errors [8]. - It records and presents the complete transaction chain of copyright information, allowing rights holders to monitor activities in real time and providing robust evidence in disputes [8]. Group 4: Future Potential - As blockchain technology evolves, MicroAlgo's algorithm is expected to undergo further refinement and may integrate advanced encryption technologies to enhance copyright protection [9]. - The algorithm has the potential to expand into specialized areas of intellectual property, such as design patents and trademarks, contributing to a more robust IP protection ecosystem [9].
