[Fwd: AW: More UB-Tree patent information]

Hi everyone,

This is Prof. Bayer's response to the question "is it alright to use
UB-Tree's in Open Source projects?".

It's a "No, but we can discuss a licensing model" type answer.

Regards and best wishes,

Justin Clift

Dear Justin,
I am personally holder of the patents.
concerning your question:
> Specifically wondering if it's alright to use UB-Tree's in
> Open Source projects.
the answer is NO, unless there is a patent agreement with me.
Please let me know, what specifically the interests and business models
are,
then we could discuss a licensing model in line with the already
existing
license agreements,
best regards,
R. Bayer
