Why do companies try to take patents out on standard schematics?

It looks like JPL has the most difficult/paranoid tenancies when it comes to information. From what I read enjoying red meat and loud music is a criterion for disqualification. Too many human traits detected.

Also,  a high-ish turnover of electronics engineers is good for a company, because each engineer injects their spectrum of knowledge into the company. So a high turn-over  of electronics engineers in a company helps a company….as such, again, companies who have a high turnover of engineers should be favoured for grant money. This would help the companies, and help the economy.

From my experience, no. High turnover results in the same mistakes being made over and over again.
Other industries might benefit though.

So was it failing or not?
If it wasn't failing why would they care.

There's no evidence that a consensus has formed to that effect. Would you not agree?

I've found no consensus either. Rather the opposite.

Many of the comments (mine among them) drifted a fair bit 'off topic", so may not be valid, but a rough count tends to give it to those who agree with Faringdon's comment :-

"Long and short is, that many electronics companies are overly paranoid about protecting bog-standard electronic schematics", if not the rest of them.

It is, however, close.

Most people actively involved in repair of Electronic equipment can tell the same stories about idiot "IP" restrictions.

Even really basic stuff runs into this.
I have recently been involved repairing my "Dick Smith D3800/Manson EP925" analog power supply.(slowly, because I am both old & lazy)

A guy who has a Youtube video about repairing such devices was asked, in the comments section, if schematics were available.
He answered that he got one from Manson "after signing an NDA!"

This, for a power supply using a LM723 regulator & five 2n3055 pass transistors-------hardly innovative design, to say nothing of the fact that full schematics are all over the Internet!

Back in the 1920s & '30s, big companies tried to rigidly protect their Patents & other stuff against hobbyists etc, but the "Genie was out of the bottle", with enthusiast magazines springing up around the planet, so their cherished "trade secrets' became "Public Domain" by default.

It probably didn't help their argument, when component manufacturers openly published "suggested designs" using their stuff!

In the present day, I have noticed that it is mainly smallish companies trying the "claiming IP for mainstream stuff" trick.
Big ones just don't supply schematics, but don't really try to justify themselves.
