A U.S. District Court in North Carolina granted EMC the injunction against Triangle Technology Services, which provides EMC-related support services and is a seller of used EMC equipment.
Under the permanent injunction, Triangle Technology is prohibited from using certain EMC copyrighted software and trade secrets relating to EMC's service business. The storage maker alleged Triangle had been using its maintenance software, training materials, engineering documents and other parts of its intellectual property without authorization.
"The violations that occurred represent only a small portion of our business, but the court's decision sends a clear message to others that the $3 billion we spent on research and development is protected," EMC spokesman Greg Eden said.
EMC became aware of the alleged violations upon talking with EMC customers who had begun to use Triangle's service as they came off their service agreements with EMC, he said.
Triangle Technology declined to immediately comment.
The court ruling offers some good news for EMC, which has seen its finances battered by slow sales in a weak IT spending environment. Earlier this month, EMC a 9 percent sequential drop in third-quarter revenue to $1.26 billion.
