Mirror, mirror, on the wall, who sues most of all? These 10 companies based on trademark lawsuits from 2001-2006 taken from the sidebar of this article:

1. Microsoft
2. Cendent
3. Altria/Philip Morris
4. Best Western
5. Dunkin’ Donuts
6. Lorillard Tobacco
7. Levi Strauss
8. Baskin-Robbins
9. Chanel
10. Nike

So what can be gleamed from this info? Either these companies are overprotective or have several others infringing on their IP.
