…And the patent jokes never end.

BlueJ, a free educational Java IDE primarily aimed at students, has contained some innovative debugging features for many years. Features that the largest software developer in the world, Microsoft, blatantly copied (without any attribution) a few years ago in its expensive commercial Visual Studio IDE. But copying was not enough for Microsoft; it would really like to patent them as its own, despite the fact that BlueJ has had them for about 10 years. Ah, let’s all cry in unison: ‘prior art’. Some of the comments on the linked page are very interesting.

[Update: The Reg reports that the patent application has been withdrawn.]
