The argument for patents is simple and clear: the alternative is broader use of trade secrets. In a patent regime, a company can (indeed must) publish their process, in exchange for a temporary monopoly on exploiting it commercially. In return, everyone else can learn it, implement it for research, and improve it, at which point the patent no longer applies. Copyright was also compelling in the technological milieu i…
I used to find this compelling, then I found out that standard practice is to avoid reading patents, because 1) they're not written to instruct, but drafted to claim broad implications and exclude prior art, and 2) exposure to patented material increases liability if you are found to be infringing.
Are there any examples of any inventor using published patents to learn from, rather than just patent searches to help drafting their own patents?

This is generally wrong - the original patent still applies. You can get a separate patent on your improvements, but until the original patent expires, you can't use the foundational invention without licensing the original patent.
