62 years ago, today – on January 28, 1958 – LEGO® owner Godtfred Kirk Christiansen applies for a patent regarding an invention which is without a doubt one the biggest milestones in LEGO Group history.
But – contrary to what many might think, the patent application is not about to the invention of just one specific type of brick.
Rather, the patent covers a building system or a building method in which two or several interlocking plastic building elements “...could be put together in a great number of mutually different positions...” (Quote from the original Danish Patent application).
For that reason, the patent also covers several different brick designs, some of which can be seen in these photos. The common denominator for these different brick designs is that each and every single one of the designs ensure that the brick has just the right clutch power, and thus the bricks have the ability to stick together – as if they were glued.
So: Happy Patent Day – to the LEGO brick – but especially to the awesome interlocking principle that combined with the LEGO System in Play provides us with endless building possibilities 😉
