What Adobe tools gives the right to use Myriad Pro Font...

Hi Allan,

I apologize for the delay in response. Here are the answers to your questions:-

1) What Adobe tools include a right to use Myriad Pro Font...Illustrator, InDesign, or even Acrobat Pro single app? And what kind of right to use it?
If you are using Creative Cloud, you are licensed to use Myriad Pro in all of your desktop applications (Adobe or non) via Adobe Fonts.
https://helpx.adobe.com/fonts/using/activate-fonts-desktop.html
and the licensing is described in this article:  https://helpx.adobe.com/fonts/using/font-licensing.html

2) What if you do not renew the Adobe license assigned to you (I.E. replace Acrobat with Kofax) – do you lose the right to use the fonts and be incompliant using it in example editing a PDF in Kofax tool?

Please refer to https://helpx.adobe.com/fonts/using/font-licensing.html#act-cancel

3) If you as a company have bought Creative Suite perpetual licenses back in the old days – you also got the Adobe Fonts. Those licenses are ours forever, is that the same with the fonts?

The font licensing for Creative Suite, which included bundled fonts, allows those fonts to be used while the software is installed. If you uninstall the software, you are no longer licensed to use the fonts.
Similarly, if you cancel your Creative Cloud subscription you are no longer licensed to use Adobe Fonts. (again, this is covered in https://helpx.adobe.com/fonts/using/font-licensing.html#act-cancel)

Hope it helps.

Thanks,

Harshika
