Conditions for use, Tet-On system
 
Back in '97, a student in our lab bought the Tet-On system from
Clontech for use in his thesis work. I work in a small biotech company
with many research-based activities and with many academic
collaborations, including this thesis work. No commercial work was
done with the Tet-On system, and the final results were published in
2001.

In 2004, the company TET Systems was formed, apparently to profit from
the Tet-patents filed by Gossen and Bujard (first patent filed
November 1995). Later, TET have contacted us and asked us to enter a
license on the system, not only for present and future use, but also
past use. As we recall it, there were no licensing conditions attached
to our purchase in 1997, but it is difficult for us to dig up that
information after 12 years. Does anybody know where I can find a copy
of the conditions of use for the Tet-On system dated around spring
1997?

Best regards,

/JT

No commercial work may have been performed, but was the Tet-On system
purchased from Clontech by a commercial entity, i.e. the small biotech
company and not the academic entity the student was affiliated with?

If it was the former then TET Systems has obtained that information
from Clontech and contacted you on that basis.

As far as I remember (from 1999), there were restrictions on
commercial use of the Tet-On system.

However, last year, I was contacted by TET Systems to complete a
new "Notice & Acknowledgement" agreement for non-profit users. It was
a little sticky for us, because we have modified the Tet-On system and
published manuscripts with the modified system.

Thanks AC.

The situation is a little sticky for us as well, since we also have
modified and published with the system. As we recall it, however,
there were no licensing conditions present when we purchased the
vectors in Spring 1997 (which was a little more than one year after
the first Tet-On patent), that appears to have come later. So, that is
why I am very interested in hearing from anybody that would have a
copy of the 1997 licensing information / conditions somewhere in their
archives.

Thanks,

/JT
