EMC said a permanent injunction has been against Triangle Technology Services.
In February, EMC sued Triangle, an authorised EMC support vendor, alleging that Triangle was using some of EMC's copyrighted maintenance software, training materials, engineering documents and other intellectual property without authorisation. EMC charged that Triangle was using the information to build up its own services business.
Under the terms of the injunction, Triangle will be prohibited from using EMC's copyrighted software and trade secrets.
"This case should send a clear message to those in the storage industry hoping to illegally prosper from our investment in intellectual property," Paul Dacier, EMC's general counsel said. "We will do what it takes to protect EMC's intellectual property investment for the benefit of our customers and shareholders."
Triangle president Mindy Barbee said that her company has entered into a settlement agreement with EMC to exit its EMC support and services business. Triangle had established its maintenance support programme in 1996 to work with third-party maintenance companies that serviced EMC equipment.
