QR Code Standardisation - - Feb 2017
The QR Code specification is standardised today, and Denso Wave have made every effort to have them standardised from their first inception. This helps ensure that no matter who creates a QR Code or builds a QR Code reader, they are all interoperable.
This in addition helps increase the uptake and the overall user confidence in the technology, as well as ensuring that the original goals of the technology remain (fast and can be scanned from any orientation).
Denso Wave have patents that protect the QR Code technology, but have stated they would never enforce them for any QR Code that is conforming to the standards. What this means is that you can use them as you see fit without needing to seek permission from Denso Wave, but if you take the specification for QR Codes, alter it slightly so that it no longer confirms, and start pumping out your own fork of QR Codes, then they reserve their right to pursue the patent.
Below is a history of the standardisation of QR Codes.
