On June 8, 2004 IBM was awarded a patent for:
"A Caps Lock notification method, system, mechanism, algorithm, and computer program product. A determination is made as to whether a Caps Lock key of a computer keyboard is in an error state, based on ascertaining whether a first condition has been satisfied. If it is so determined that the Caps Lock key is in an error state, then a signal is generated to communicate to a user at the computer keyboard that the Caps Lock key is in the error state. The signal may be a visual signal, an audible signal, a tactile signal, an auditory signal, or a combination thereof. Satisfaction of a second condition may be used to disable the signal."
