I would argue that most of those are bad patents, which should not have been issued. One of the criteria for being awarded a patent is that your invention be non-obvious to an expert in the relevant field. If just looking at the product is sufficient to disclose everything you need to reproduce it, that doesn&#x27;t <i>necessarily</i> mean that the idea is &quot;obvious&quot;, but it should give one pause, and warrant further investigation into whether or not this particular invention is really worth patenting.
