Hey look - these clowns at Visto who are suing Microsoft think they invented TCP/IP and various mail protocols:

Visto has been at the forefront of developing mobile communications solutions for nearly ten years. Company co-founder Daniel Méndez and others developed the system to allow consumers to securely receive their email and other sensitive data via mobile phones or other mobile devices while traveling. Méndez and Visto went on to patent the system that drives email from personal or business servers to mobile devices like cell phones and allows users to access sensitive data and email stored behind highly secure corporate firewalls.

So if I have Cincom Smalltalk installed on a "Smart Phone", and I use IMAP to access a mail server, am I infringing their patents? Their CEO, Brian Bogosian apparently thinks so. I guess I'll have to watch which devices I use to collect email with in the future. Sheesh, what a maroon.
