Yeah this is bad, seeing what some people patent, apparently just hoping it will stick and make them some money down the line.
I was going to put some particularly egregious examples here, but there's too much choice - just search "worst dumb us patents" or some such.
OK, this article focuses on dumb and pointless, which is what I was going for:
2. A stick. Seriously, in 1999, someone received a patent for a toy made of “any number of materials including rubber, plastic, or wood including wood composites” for “an animal, for example a dog, to either fetch, carry or chew” and including “at least one protrusion extending therefrom that resembles a branch in appearance.” While the description is bad enough, you have to look at the image submitted to fully appreciate how ridiculous this one is. USPTO actually granted a patent on a fake stick.
1. My all-time favorite dumb patent is Apple’s design patent for… a rectangle with rounded corners. Granted in 2012, Apple received a patent for the shape of its product, which is pretty standard. It’s a rectangle. It has rounded corners. The entirety of the single claim reads, “The ornamental design for a portable display device, as shown and described,” with several pictures of what looks to be the shape of an iPad.
