Need info about Patran Neutral file

[kinma]

Could you please help me to get any info about Patran Neutral file.
Unfortunately, I could not find this information on the developer website

http://www.mscsoftware.com/.

I need to know whether we (as a software company) can use Patran Neutral file format in our software packages and if yes, on which terms we will be able to do it.

Thanks in advance.
