a quick release feature for socket wrenches. The feature allowed a person using such a ratchet to remove the socket from the wrench with one hand, freeing the second hand from grabbing the socket while the other hand held the ratchet. Roberts developed a prototype and applied for a patent in 1964. While the patent was pending he approached Sears and introduced the idea to them. Sears, which sold millions of sockets every year, saw the potential in the invention and asked for the prototype so it could be tested. After testing revealed the quick release would not weaken the ratchet, Sears began market testing the new ratchet and received favorable feedback. Sears then incorporated the quick release into a new line of ratchets, projecting sales of up to 750,000 units in the first year alone. In January 1965, Roberts received a phone call from a Sears attorney asking for the name of Roberts' patent lawyer. Without Roberts's knowledge, Sears hired the patent lawyer, Charles Fay, and Fay ended up representing both Roberts and Sears regarding the patent. Around this time, Roberts's patent was approved, but Fay did not reveal this to Roberts. Negotiations for use of the quick release commenced, with Roberts being told that the quick release wasn't new and that any patent issued would be limited. Sears's lawyers also said that because of the cost (44 cents per wrench) of adding the quick release to the wrenches, a license was worth only $10,000. What Sears didn't tell Roberts was that it planned to make 50,000 of the new wrenches per week. Roberts sued Sears in 1969 after seeing his quick release on a wrench prominently displayed in a Sears catalog, but it wasn't until 1989 that the case was finally settled. Neither side revealed the amount of the settlement. In August 2002, Sears sued Emerson for using Sears-owned manufacturing equipment to create power tools for Home Depot. Upon the expiration of Emerson's 30-year contract to make Craftsman tools, Emerson was required to return the Sears-owned equipment. Instead, Emerson kept the equipment, claiming it to be obsolete and of little value. Emerson denied the allegations when the suit was filed, but paid Sears $10.8 million and returned all the equipment, while admitting no wrongdoing. In 2004 a class action by customers accused Sears of false advertising and consumer fraud for questionable use of the slogan "Made in the
