In 2015, Delaware North sued the NPS in the United States Court of Claims for breach of contract, claiming that the contract with Yosemite Hospitality excluded intellectual property from the asset purchasing clause, and demanded a payment for the property to be determined in court. Delaware North initially asserted the fair market value of its properties to be $51 million, but the National Park Service estimated the value of the intangible assets at $3.5 million. Delaware North claimed to have offered to temporarily license the trademarks while the dispute was unresolved and further claimed that the government did not respond to its offer. The dispute gained national attention after it was publicized in an issue of "Outside" magazine, which led to the Sierra Club issuing a petition requesting that Delaware North drop the lawsuit.
