Clive Sinclair
Uncle Clive used "innovative"¹ technology to run his cheap, shitty pocket calculators back in the mid-70s. Maybe Qualcomm can claim prior art.
¹Innovative as in running chips way outside their specs.² Pre-test the chips to see if they performed outside of spec, throw away (or sell on) those that fail. Throw away (or rework) assembled devices that fail production testing. Accept a large number of returns because even those that passed both sets of tests were likely to be marginal and fail as they age.
² He took desktop calculator chips and reduced their average current consumption by pulsing the power rail. It gambled on the capacitance of CMOS gates retaining enough voltage while the power was off that it would not lose state when the power returned. Most of his products relied on using components outside their spec.³
³Including his very first product, the MAT101 transistor. This was at a time when transistors were new and very expensive. His were merely expensive. They were also Plessey transistors that had failed testing and were outside spec, but still retained some marginal transistor action. So that was all he claimed: that they exhibited transistor action and could be used for experimenting, not that they could be used in any practical way.
Almost, but not quite, as deceptive as the Japanese company that bought defective Ferranti transistors. They used them in their radios. The standard superhet design of the time used 6 transistors, and radios from all manufacturers used to boast in the advertising and on the case of the radio itself that they were 6-transistor designs. This company released a 7-transistor radio. The seventh transistor was a dud and not connected to the rest of the circuitry, but the radio had 7 transistors, so was obviously better.
