<p>Indeed, from my perspective, having a clear patent policy is the primary (sole?) virtue of the ISO standardisation of OFF.

<p>The MS math layout patents are yet another case of lack of explicit statement creating potential uncertainty. We can accept the likelihood that the patents were registered for defensive purposes, and that Microsoft would not seek licensing fees or restrict
use based on those or other patents related to fonts, but likelihood and goodwill are not certainty.<u></u><u></u></p>
<p>Dave is right that inclusion in OFF should be a good case study of patents in the format.<u></u><u></u></p>
