Sitting on the fancy press machine and noticed for the umpteenth time that the weights had a patent number. Not only that, but a pretty recent patent, way up in the 5 million range. And it was finally enough for me to ask myself, what is there that's patentable about a weight? Here's a pic of the culprit:
So what did I do? Found the patent, of course! And here's the first page:
1992 so not super new. And look what it was that got the patent for them. A couple of holes in the plate. Anything else? Nope, not really. Just two holes to make holding it easier.
There used to be metal in those places but now, due to this patent, there's nothing. So there you go, a patent for nothing!
