Re: trademark infringement FreeFOAM

I have to correct  something: Holger Marschall, the author of the
"OpenFOAM Documentation Project", explained me he only received some
emails where OpenCFD threatened him to write a letter of legally valid
cease and desist letter. He actually did not receive it as he put down
the website. Also, after he named it to "FOAM Documentation Project",
which was put down after OpenCFD complained.

As stated in the OpnCFD trademark policies, the naming OpenFOAM and
abbreviations are explicitly forbidden.

That said I wonder if FreeFOAM is considered as trademark infringement,
even by OpenCFD, as a derived naming is not explicitly mentioned to be

Therefore, I still have my doubts if even renaming of the FreeFOAM
project is required. I will ask an attorney at our university for this.
In addition, the trademark 'Freefoam' has already been used by a
construction company and I found two registered US trademarks
(extrusion / machinery and a travel luggage and bags company). Whether
these companies will be annoyed by our software project remains to be
seen. At least, this might obstruct OpnCFD to go after FreeFOAM.

Thanks a lot for your contributions in searching a new name for the
FreeFOAM project. We will definitely take them into account.

I didn't know that and that's quite strong. Do they also erase the names
of contributing authors, as OpenCFD is requiring?
