• In 2020, Represented a director whose company's business license was revoked but not liquadated in a retrial case between him and the company's creditors in a liquidation liability dispute at the Hainan High People's Court and Haikou Intermediate Court. Despite facing an adverse situation where the director was already found jointly liable for over 100 million yuan of the company's debts, the re-trial process successfully overturned the original verdict, leading to the dismissal of the company creditors' lawsuit against our client and exempting our client from any liability.
• In 2021, Represented a multinational electrical group in a second-instance case at the Supreme People’s Court, claiming that the actual controller and affiliated companies of its debtor should bear joint and several liability for the transfer of the debtor’s assets and infringement of the creditor’s rights. The client’s claims amounted to more than US$360 million. We successfully overturned the first-instance verdict and achieved a major breakthrough in piercing the corporate veil in various dimensions. This case won the China Business Law Journal Deal of the Year of 2022.
• In 2021, Represented a private equity fund management company in an arbitration, addressing whether the private equity fund manager acted diligently and fulfilled his obligations, which involved claims against our client for compensation exceeding 15 million yuan. Ultimately, we achieved a satisfactory result in which the client, as the manager, was exempted from liability for compensation.
• In 2022, Represented a financial institution in an arbitration accepted by the Shenzhen International Arbitration Commission, where we sought liability from the private equity fund manager for investment losses. The ruling confirmed the manager's breach of fiduciary duties, ordering compensation of 93 million yuan, with actual recovery exceeding 100 million yuan, marking a groundbreaking precedent for protecting private equity investors’ rights.
• In 2023, Represented a leading Danish biotech company in a patent infringement lawsuit against an enzyme preparation company at Beijing Intellectual Property Court and the Supreme People's Court. Both first and second instances confirmed the infringement and awarded 22.05 million yuan for economic losses and 1 million yuan for reasonable expenses, one of the highest compensation amounts in domestic patent disputes.
• In 2023, Represented a renowned scientist who developed the first CAR-T drug approved for marketing in the United States in a lawsuit against a Hong Kong-listed biotech company regarding trade secret infringement at Nanjing Intermediate Court and the Supreme People's Court. We successfully thwarted the biotech company's attempt to use this case to prevent the Cayman Court from ordering its affiliates to return more than 3 billion yuan worth of Nasdaq-listed company shares to our client.
• In 2023, Represented a controlling shareholder of a listed company in an arbitration regarding a special relief investment and voting rights delegation agreement at the Shanghai International Arbitration Center. Despite our client's breach of contract, we creatively argued a contractual deadlock defense, leading to a settlement that fully realized our client's demands to terminate the agreement and recover actual control of the listed company.
• In 2024, Represented a coal company in an arbitration at the Beijing Arbitration Commission concerning a share repurchase agreement. Despite our client failing to pay the full repurchase amount on time and the counterparty attempting to terminate the contract, we secured a complete victory ruling for the transfer of disputed shares worth approximately 2 billion yuan to our client and the return of 230 million yuan in dividends.
• In 2024, Represented a golf club in a series of lawsuits against its partner arising from the golf course concession agreement. Secured a complete victory for the client despite the unfavorable circumstances where the contractual cooperation term had not yet expired and the opposing party had prematurely alleged breach of contract. The court ruled that the client had not breached the contract, that the opposing party had committed fundamental breach, upheld the client's termination of the contract, and ordered the opposing party to return the golf course and compensate for losses.
• In 2025, Represented a financial institution in a dispute against a fund management company over losses incurred from investing in a private equity fund. The client demanded the fund manager fulfill repurchase obligations under a forward repurchase commitment letter. Despite legal challenges—including the invalidity of the manager's repurchase commitment due to its constituting a rigid redemption obligation and the manager's liability capped at 50% compensation— and the client sought compensation exceeding 50%. Pioneering a novel approach, we formulated a dual-claim litigation strategy: asserting the manager's liability for management negligence as the primary claim, supplemented by the manager's repurchase obligation as an additional claim. Through meticulous factual analysis and legal argumentation, ultimately achieving a decisive victory far exceeding the client's expectations. Both trial courts ruled that the fund management company should bear 100% liability for compensation, ordering it to reimburse the client for the full principal investment loss of 100 million Chinese yuan plus interest.
