Apple is slapped with a patent lawsuit over the iPhone's browser

I know what you mean. I use Ctrl-+ (Control-Plus) and Ctrl-- (Control-Minus) to enlarge and shrink text on the page. Firefox is nice because that also enlarges and shrinks images; Chromium doesn't do that.

I like to use control plus the mouse wheel to zoom in/out in the web browser -- not sure if this is what you mean by zooming.

One feature I like about Ubuntu's 3D-accelerated window manager is that it can zoom windows -- which is different from maximizing them because it makes everything (including menus, etc.) proportionally larger. So the "Windows key plus R" zooms until the focused window fills the screen. Win+1 zooms to standard desktop size, Win+2 zooms to double size, and Win+3 zooms to quadruple size, which are great for watching Flash movies that don't have a fullscreen option.

I wonder if patent trolling could be patented? A time machine would be fantastic.

But you can't. If you are a large corporation, the only thing determining whether an opponent is a patent troll is whether you can dig up a patent of your own that the opponent is violating. If you can, you can use the mutual threat to enter a patent sharing agreement. If you have no way to threaten the opponent, they must be a troll.

To them, there is no effective difference between a company that only files patent lawsuits and a startup that has been forced out of the market by competitors that are violating its patents.
