H.C. Starck, one of the leading manufacturers of technology metals and advanced ceramics, has filed a patent infringement lawsuit against Ningxia Nonferrous Metals Import and Export Corporation in the United States. The suit is based on the infringement of a patent held by H.C. Starck for highly capacitive tantalum powders and sintered anodes that are manufactured from these powders. These materials are used in the electronic industry to make capacitors for state-of-the-art, high-performance electronic devices like smartphones and tablet PCs.

H.C. Starck filed its first patents for technology metals over 60 years ago. Today the company holds around 900 issued patents worldwide as well as an equal number of pending patent applications, and invests 2.5 percent of its annual revenue in research and development.
H.C. Starck pursues a consistent strategy of protecting its intellectual property and will continue to enforce its claims to also guard the interests of its customers.
