LS Cable & Systems Ltd. appears in patent litigation as a defendant in one tracked case. This indicates a posture of an operating company defending against patent assertions, rather than an entity actively asserting a patent portfolio. The single case, Unified Patents v. LS Cable & Systems Ltd., is before the Patent Trial and Appeal Board (PTAB).

In the Unified Patents v. LS Cable & Systems Ltd. case, LS Cable & Systems Ltd. is the defendant in a PTAB proceeding. Unified Patents is an organization that challenges patents it believes are invalid, often acting on behalf of its members who are operating companies seeking to deter abusive non-practicing entities (NPEs). The PTAB proceeding suggests a challenge to the validity of one of LS Cable & Systems Ltd.'s patents. LS C&S holds numerous patents related to high-voltage power cables, optical cables, and bus duct systems.
