New air con invention, but how does it work?

[Tim+]

Actual patent viewable here but as John says, little of substance.

I suspect it’s main function is to separate investors from their money.

Yep and I do not see any way for that to happen.

FWIW That is my impression too.

I will enquire as to how such a vacuous patent has actually got as far as being registered at WIPO with so little content or claims.

Most of the abstract is PR fluff about how it doesn't use an active phase change medium but does not describe the invention at all!

There is no description even in the most basic terms of what the invention "air disc" compressor (the actual invention if it is one) consists of. I fail to see how patent examiners would let that go.

OTOH I have always had the impression particularly with USPTO that if your dollars were green and supplied in sufficient quantity you could patent any damn thing you like. It is only quite recently that they stopped accepting patents for perpetual motion machines!

TBH I'd be surprised if it did enough useful cooling work to shift the waste heat generated by the motor powering it! There is no indication of any heat sink so either something is missing or it is not viable.

[Martin Brown]

It would also need a very chunky heat sink to lose the heat quickly enough to be useful. IOW I think it is probably marketing BS.

I have seven granted patents. The first was a joint affair with my manager and project leader, just after the company I worked for had been bought by a large US multinational to which I shall refer only by its initials, GE.

Basically, they had a web-based patent mill. After the first one, I saw that it was easy so I did six more in the time it took to get out of what was a small innovative company which had become an exercise in wading through treacle. The incentive was a cash reward for each one granted, and the odd trip out to have lunch with a patent agent in the west end.

One was, I think, innovative, and another pretty good too, but some of the others were simply taking the piss (and the cash), there was no way they'd stand up to any sort of scrutiny. These were all US patents save one which was Chinese. Good on the CV though.

I believe they do it so they can bully smaller companies.

In a subsequent job I had a few signal-processing algorithms which may well have been novel, but the risk in applying for a UK patent was too great - all it takes is someone to show prior art and you've given your 'secret' away for nothing. And realistically, in that field it's quite likely that someone else has already 'invented' the same algorithms and not applied for a patent for exactly the same reason.
