Contributor Agreement

The projects developed by the Open Source Research Group at the University of Erlangen-Nürnberg are intended to be

Open Source and Sustainable.

However, there are threats to these goals:

  • A contributor withdraws permission post­ facto.
  • The project needs to change license at a later point.
  • A patent infringement lawsuit is filed against project users.

Our answer to these threats is the use of a Contributor License Agreement which

  • ensures the use of an Open Source License,
  • allows for Later License Change and
  • provides a Full Patent Grant.

If you want to make a contribution please download the Contributor Agreement used by the OSR Group, complete and sign the form, then scan and email a pdf file to You may also send the signed form by facsimile to the OSR Group at +49 9131 85 20321.

    A: No, you’re granting us some of your rights, but that doesn’t take away these rights from you.

    A: Yes, practically all foundations (Apache, Eclipse, FSF, …) but also companies involved with Open Source (IBM, Red Hat, MySQL, …) require Contributor Agreements.
