It's possible. They are in interesting company. They have done a lot of research in very interesting subjects.

I dug some with Gemini. Looks like they did. A couple of references I could find:

- IBM Graphic Design Guide: https://designreviewed.com/artefacts/ibm-graphic-design-guid...

- AFP (for printing any typography, I believe): https://www.ibm.com/docs/en/i/7.6.0?topic=concepts-afp-resou...

- Looks like part of their first font specifications still live in OpenType spec: https://learn.microsoft.com/en-us/typography/opentype/spec/i...

Wow.
