A federal court in Houston has entered an order finding that a product line sold by Canadian-based Liveline Solutions, Inc., infringes on United States Patent No. 5,538,207, which belongs to Quanta Services and is known commercially as the patent for the company's LineMaster robotic arm. Liveline Solutions previously marketed and sold the infringing products — branded as PowerArms — to customers in the United States and internationally.

The Quanta Services LineMaster robotic arm enables the company to service virtually any voltage line or facility in an energized state and thus not interrupting the flow of electricity to consumers. Through the use of the LineMaster robotic arm, Quanta's team safely, efficiently and effectively isolates energized lines from structures to perform energized reconductoring services. Quanta is the exclusive operator of the LineMaster robotic arm.
