[MPEG-OTSPEC] MATH Encumbrance

[Peter Constable]

It’s best not to bring up specific patents in cross-company discussions since some companies have policies requiring employees to exit discussions if other parties mention any specifics regarding patents. (Triple indemnity being a bit scary and all.)

I will say that I was a party in some patents in my time at MS that were filed solely for defensive purposes, never with any intent to charge licensing fees.

In the font space, I’d suggest that licensing fees could result in diverging formats and renewed font wars, which nobody wants. It’s not like video formats or something that takes rocket science to eke out the next leap in performance. Nobody significantly benefits if fonts don’t just work everywhere.

Is that because of a MPEG OFF patent policy applying to https://patents.google.com/patent/US7492366<https://eur04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpatents.google.com%2Fpatent%2FUS7492366&data=02%7C01%7C%7C53c05d63fab6437ad0f208d84648bf3b%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637336625538947643&sdata=wk5EfhxAX6gD%2B3hDij9qdiT2Utl%2F%2BzcYDqqwvgScpzU%3D&reserved=0> that means a license isn't required?

Hi

Does MATH table implementation require a license?

Cheers
