US Lawmakers Move to Expand Tech Blacklist as Lenovo Faces Patent Probe

Items on such a list cannot be legally imported, marketed, or sold as new products within the US. Separately, Lenovo Group has become involved in a patent dispute concerning memory devices. The two developments arrive as US lawmakers pursue broader authority to restrict technology products.
