A broken ice cream machine is a familiar inconvenience to McDonald's customers.

Franchise owners have complained about difficulties fixing the machines, McDonald's itself has poked fun at how often the machines are seemingly broken, and there is even a dedicated independent site for customers to see when and where they might be denied a McFlurry.

Those worries may soon be a thing of the past, after the U.S. Copyright Office issued a new set of exemptions last week that allows restaurants to repair equipment used in "retail-level commercial food preparation," which includes those soft-serve ice cream machines used to make McFlurrys.

Public Knowledge, a consumer advocacy group, and e-commerce website iFixit petitioned the U.S. Copyright Office for the exemption, which went into effect Monday.

"There’s nothing vanilla about this victory; an exemption for retail-level commercial food preparation equipment will spark a flurry of third-party repair activity and enable businesses to better serve their customers," said Meredith Rose, senior policy counsel at Public Knowledge.
