Luca, OpenDDR are claiming that they are using WURFL data under the terms of the license applied to the version of the data they are are using. You are claiming that they are violating your copyright. 1. Are you asserting that they are misrepresenting which version of the data they used and are therefore violating the new licensing terms? 2. Are you asserting that they are using the version they claim, but that they are violating the terms of the license applied to that version of the data? 3. Are you asserting that the terms of the new WURFL license somehow apply retroactively to versions of the data that predate the license change?
