Yeah, and too many too trivial things can get patented. For example, Canon sued 3rd party ink cartridge manufacturers because they had patented a "T-shaped division" inside their cartridges to separate the three colours.
If
this can be patented (and I bet it only can be patented if you are a company with big $$$), when will another company come and sue all manufacturers of longdrink glasses because the company has patented "a hollow, upright cylinder with a bottom"...
Jeez.
