Not that this would be an efficient use of anyone's time but... Assuming the purpose of patents is 1) to eliminate trade secrets, 2) that patents must be novel, and 3) that patents must be non-obvious to someone skilled in the art, then perhaps a solution would be: take a handful of people skilled in the art, tell half of them to implement the patent and tell the other half only the end goal and see if any of them co…
the costs of your system are probably way more than the value created for society via patents.
1) Patents enable "benevolent monopolies." Companies that can afford to splurge on fundamental research because they have a revenue source protected by some sort of barrier to entry or network effect. Xerox PARC, for example, created many of the technologies fundamental to modern computing. PARC was bankrolled by Xerox's near-monopoly on copiers, which was enabled by Xerox's patents. PARC's decline closely tracks what happened after the 1975 consent decree in which Xerox was forced to license its patents to Japanese competitors.
2) Patents enable business models that separate design from production. ARM and MIPS, for example, design chips incorporated into designs from myriad manufacturers. How much value has been enabled by proliferation of these IP cores? You may point to things like RISC V, but that only proves the point. RISC V followed 15 years after the first ARM licenses, and has a fraction of the capital backing it. It's a lot harder to raise capital to build designs with the idea that you're going to give away the work product for free.
3) Patents enable technology sharing. Dozens of different companies have technology that is included in DVD, Blu-Ray, 2G/3G/4G, Wi-Fi, etc. Companies contribute the results of very expensive R&D efforts to these openly-published standards because they can ensure they get a cut of the value created by that technology. If they could not, there would be strong incentives to keep that technology secret instead. You might point to the success of web standards in the absence of patent protections. I'd posit that the web is the exception not the rule, and it's an exception that exists because of how easily the web can be monetized with advertising. That monetization strategy is not widely applicable.
