Just a nit: IIRC their patent didn't cover the idea of "interactivity", but something more along the line of "plugins", which is what the "external programs" refer to. Active-X is why they targeted Microsoft.

Thank you, you are correct--I should have been more careful.

Just claiming the idea of plugins (and not interactive browsing in general) is less ridiculous, but still dangerous.
