> I have serious doubts that more examination time is the solution here - at the end of the day, the only people that have an incentive for completely thorough search are the people filing or defending themselves against the patent. And the people filing obviously make sure their language doesn't easily bring back prior art. Meanwhile you have no skin in the game at all.
While I agree with you that multiple stakeholders are incentivized to do thorough searches, not everyone agrees on that, and those stakeholders rarely ever do thorough searches. People aren't Homo economicus.
Applicants are required by law to provide prior art on an IDS form. Usually that prior art is close but not close enough. And almost no one submits third-party prior art. I've never once received a third-party prior art submission.
And as I said, not everyone agrees that these folks are incentivized to do good searches. For example, many patent attorneys recommend against doing patent searches for various reasons.
> I would posit the better solution is curbing overly broad/abstract patent language that can be used to litigate anything and anywhere
I strongly agree that enablement requirements should be higher. My understanding is that would require a change in the law, which would make this much harder than increasing examination time. And don't think that enablement rejections will take a lot less time than prior art rejections for examiners. Attorneys love to argue that sort of stuff, so rejections which are basically arguments are often time consuming. A prior art rejection can leave a lot less wiggle room for attorneys.
(Again, like my other comments here, this is just my opinion, not that of the USPTO or US government.)
