TET Systems offers licensing models tailored to your needs

The Tet Technology is accessible to everyone, but depending on the type of organization and use, different licensing models apply to non-profit and for-profit entities.

It was always the inventors’ philosophy to make the Tet Technology accessible to non-profit organizations free of charge for their own, internal research projects.

For other applications (e.g. sponsored research) or for use in for-profit organizations, specific licensing models are available. TET Systems will offer the best fitted license model for your specific needs.

Due to the unique properties of the Tet Technology, TET Systems has built long standing relationships with its customers and partners with 90% of the world's Top 20 pharma companies being licensees.



Non-profit entities are allowed to use the Tet Technology for their internal R&D free of charge under a cost free limited use license. Under this limited use license the following uses are excluded and require a commercial license:

  • Sale or otherwise transfer the Tet Technology or its component parts to third parties.
  • Research using the Tet Technology being sponsored by for-profit organizations which shall receive ownership to any data and results stemming from the sponsored research.
