Nanoco Group plc (LSE:NANO) has lodged an answer and counterclaims in the US District Court for the Eastern District of Virginia against Shoei Chemical Inc. and Shoei Electronic Materials, Inc., alleging infringement of multiple US patents related to its quantum dot technology. The filing responds to an earlier declaratory judgment action by Shoei, which sought confirmation of non-infringement following its 2023 acquisition of the majority of assets from rival quantum dot producer Nanosys.
Nanoco’s action targets a supplier that is integrated into the global technology supply chain and forms part of the group’s broader strategy to protect and monetise its intellectual property portfolio. The company is being represented by Dallas-based intellectual property law firm Caldwell, Cassady and Curry and has confirmed that the litigation will be funded from existing cash resources. The case is expected to proceed to trial in 2026. Management has highlighted the action as a continuation of its IP enforcement approach following previous successful outcomes against Samsung and LG, while also cautioning investors that litigation carries inherent risks and uncertain financial outcomes.
From a market perspective, Nanoco’s outlook remains weighed down by weak financial fundamentals, including ongoing losses, negative cash flow metrics and balance sheet pressure. Although recent earnings commentary provided some constructive strategic updates, technical indicators and valuation measures continue to reflect bearish sentiment. Progress in areas such as the image sensor market and efforts to reduce cash burn are viewed positively, but these factors are currently overshadowed by broader financial and market challenges.
