Rockin’ Patent – Georges Jenny’s “Cathodic Coupling Oscillator For Electronic Music Instruments”

US Patent No. 2,562,429 – Georges Jenny – Cathodic Coupling Oscillator For Electronic Music Instruments - Patents Rock - Russell IP
  • Rockin’ Patent®: US Patent No. 2,562,429
  • Filed: 23 May 1947
  • In the name of: Georges Jenny (inventor)
  • Title: Cathodic Coupling Oscillator For Electronic Music Instruments
  • What’s claimed: “In an electronic music instrument in combination, an oscillatory vacuum tube system tuned to audio frequency; said system including a first and a second triode element each including a cathode, a grid, and an anode; an electrical connection between said cathodes; an electrical connection between the grid of said first element and ground; a variable resistance connected between the grid of said second element and ground; and a condenser connecting the grid of said second element to the anode of said first element.” 
  • Why this patent rocks: This patent appears to relate to the ‘Ondioline’, built and patented by French poet and musician Georges Jenny. The Ondioline was a monophonic vacuum-tube instrument using a single multi-vibrator oscillator. An article by National Sawdust claims that by design, the Ondioline ‘can mimic most symphonic instruments: everything from a trombone to a violin.’ For a detailed take on the Ondioline, see here. See here for an article about Australian musician Goyte resurrecting the sounds of the Ondioline.

In other situations, there’s a need for the UK Intellectual Property Office (UK IPO) to move faster. Perhaps a competitor is gearing up to launch a similar product, an investor is asking to see patent grants
