In July 2012 the European court of Justice ruled that the trading of “used” software licences is legal and that the author of such software cannot oppose any resale. Since then, many organisations have followed the path of buying and selling licenses to stay compliant. This sounds easy, and definitely could be.
But to make this happen, organisations first need to have a clear overview over their software assets. Implementing a Software Asset Management tool will help you to get this overview. What licenses are you actually using? Which software is installed and to what extent is reassigning licenses between for example subsidiaries an option? A compliance report will give you transparency into which licenses you are missing or which are surplus.
And then what? You can easily buy new licenses from your software license reseller or the software publisher in question when your organisation is incompliant. In case of overcompliance, you can of course always put them in stock and stop paying for maintenance and support.
