For reference, here are the seven patents in question.

7,634,504 - Natural Language Installer Set Up for Controller (http://www.google.com/patents/US7634504) - The claims really are as broad as the title implies, claiming to cover any system that presents the user questions in natural language, allows the user to select among multiple choices, and then modifies the HVAC settings based on their response.

7,142,948 - Controller Interface with Dynamic Schedule Display (http://www.google.com/patents/US7142948) - Claims to cover any controller that can change temperature from one temperature to a second temperature, while displaying an ETA for reaching the second temperature.

7,584,899 - HVAC Controller (http://www.google.com/patents/US7584899) - Claims the idea of having a movable housing over a display that, when rotated, changes an HVAC-system parameter that is reflected on that display.

7,159,789 - Thermostat with Mechanical User Interface (http://www.google.com/patents/US7159789) - A rotatable selector with several selectable positions, and a potentiometer. For an HVAC system.

7,159,790 - Thermostat with Offset Drive (http://www.google.com/patents/US7159790) - Some more rotatable-selector inventions, involving linking mechanical position and electrical signals.

7,476,988 - Power Stealing Control Devices (http://www.google.com/patents/US7476988) - Something to do with switching between primary and secondary power sources. My EE is too rusty to figure out exactly what this one is claiming without spending more time than I'd like on it.

6,975,958 - Profile Based Method for Deriving a Temperature Setpoint Using a 'Delta' Based On Cross-Indexing a Received Price-Point Level Signal (http://www.google.com/patents/US6975958) - Claim 1 is even broader than the title, claiming to have invented and patented the idea of adjusting an HVAC system's setpoints based on communicating with a remote host.

They strongly have the flavor of taking some standard control method (rotating knobs attached to potentiometers, 1950s-style feedback control & rate prediction), tacking on "for an HVAC system", and deeming the result, which applies standard control techniques in the obvious way to the domain, an "invention".




Goes to show that it's not just software patents that can be utterly ridiculous in their breadth... Here we seem to have half a dozen examples of the one-click patent applied to thermostats.

The sheer amount of obvious non-innovations that the patent office accepts is staggering.

Anecdotal personal experience being part of patent applications has showed me that almost any idea, as long as there are no mainstream examples of prior art, can be patented given time (will take 4-5 years these days) and money. Most decently smart people will come up with patentable ideas all the time, just doing their job, but won't file because they don't have the desire or resources (and don't understand why their only somewhat-novel obvious-to-them idea is patentable).

"The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying." - John Carmack

It's as if patents serve to stop innovation from happening rather than help make it happen, more often than not.

Not sure if you are being sarcastic, but there is some research to back that claim (http://www.readwriteweb.com/archives/study_says_patents_hind...)

Will the America Invents Act change anything to this problem? Or should it require another reform?

"The sheer amount of obvious non-innovations that the patent office accepts is staggering."

You'd almost think that they were getting money for accepting patent applications...

<Edit>This is a perfect example of mismatched incentives. The patent office has a lot of incentive (in the form of attracting user fees) for issuing dubious patents, and no real disincentive for doing the same.

Well, an incentives discussion which leaves out the other party is not quite valid.

Although, if I were to take your implication correctly - there should be no incentive to take a patent or reject a patent other than its merit.

Which would in turn imply no cost on applying for a patent, except its applicability after review.

But that would also create a perverse incentive for firms to submit patents all the time - there is no cost involved, no barrier of entry and hence no loss in making the effort.

Alternatively, we could have a very quick review system, which would mean that soon after patent submission you get rejection or acceptance. Which would mean that the patent office would need significantly more funding - considering the number of patents it receives vs people who have to review.

If there was a solution which could automate the search for prior art, that would be cool, and a way to reduce the size of the work load.

I wonder though if perhaps fixing the patent office is a dead end, and that instead the patent office should be treated merely as a record holder, were you pay a fee for a shallow review and a time stamped filing, and then you need to use the court system to uphold them. Upholding patents should be much costlier than it is today. That is to say, it should be costlier if you file a claim that has no merit. That way it would be up to these assholes to determine wether or not they have patented something that is of actual value.

Thing is with all such suggestions, they inevitability are of the type: Fix complex system X by removing system X.

Its do-able, but I am certain that the law of unintended consequences was written to describe situations like these.

For example, in your suggestion, the part where we move the onus onto the courts, will gum up the courts. I live in India, where courts are constantly arbiting cases, and people know that if your case gets into court, it could be there for ever. Thats not a side effect we want to induce.

Now you could build in redundancy for that eventuality by expanding the number of people in court, justices and areas, but then in essence, you are moving the burden from department X to department N, with the added problem that those new people will be from law, and not a technical background.

I really do think that this is a case where people should just get someone whos a technocrat in charge, give him authority and funds, and then forget about it while the patent office is built back up into an institution that people respect.

Replying to myself for posterity: an EE friend assures me that the "Power Stealing Control Devices" patent is also completely standard practice, a technique of powering a device by siphoning off some current from a control circuit, which is a completely normal and not-at-all new tool in the circuit-design toolbox.
