Jackson Walker partners Sara Hollan Chelette and Amanda Zimmerman also represented Summit Energy Services. The case involved a contested patent for technology used in casing oil and gas wells.
U.S. District Judge Alfred Bennett ruled the design patent was invalid due to a lack of ornamental design of the centralizer; its design was primarily functional.
Chris Rourk spoke to Texas Lawyer about the ruling.
“The decision was that the asserted patent is invalid, and we believe that the judge ruled correctly based on the facts and the law,” Rourk said.
