First, the judgment banned the sale of it. It said nothing about existing copies in use, so you should be fine no matter what .
Second, I cannot see that decision standing. It was made by a district court somewhere in Texas. The plaintiff is a small patent holding company nobody has heard of. They decision will be appealed, and Microsoft will not be on the losing end when all is said and done.

I always hated Word. Whenever I was asked to do a project I always tried to look for some other publisher to use. I will be glad if they get rid of it, Open Office is way better plus its free!
