Honeywell Vs Nest: When the Establishment Sues Silicon Valley
An anonymous reader writes with this quote from an article at TechCrunch:
"Honeywell filed a multi-patent infringement lawsuit against Nest Labs and Best Buy yesterday. The suit alleges that Nest Labs is infringing on seven Honeywell patents. Honeywell is not seeking licensing fees. The consumer electronic conglomerate wants Nest Labs to cease using the technology and is actually looking to collect damages caused by the infringement. Damages? Bull****. This is about killing the competition."
Patent hold get to license the technology or not, based upon their own preferences. You can't FORCE a company to share it's patents.

They are indeed extremely lame-looking patents, even by the usual standards of patent lameness. Several of them are an attempt to patent early-20th-century button/knob technology, and several others are an attempt to patent standard 1930s-50s control theory. Oh, except with the phrase "used in a thermostat" or "in an HVAC system" added, which makes it totally novel.
One of the patents is for this earthshattering invention: a system that can change from an initial temperature to a second temperature, while indicating on a display an ETA for reaching the target temperature.
Another one is for this: a display with a circular housing over it, where rotating the housing, by means of a potentiometer to which it is attached, changes an HVAC system parameter.
And yet another one is this: a display that asks a user questions in natural language, displays a menu of possible responses (such as "yes" and "no") among which the user may select, and then adjusts an HVAC system's configuration as a result of the user's response.

Nest keeps being referred to as novel and innovative in the article and honeywell as the old giant, yet how can that really be when they clearly infringed on patents that honeywell previously had. Honeywell was clearly more novel and innovative before Nest even existed.

Honeywell's thermostat is parasitically powered, not their sensors. I'm saying the general technique - drawing power from other devices over e.g. data lines - is obvious to anyone skilled in the art of circuitry.
Here's a Maxim DS18S20 1-wire parasite-powered digital thermometer chip. http://www.maxim-ic.com/datasheet/index.mvp/id/2815
Arduino parasitic power. http://www.arduino.cc/playground/Learning/OneWire
Hell. RFID chips derives power parasitically from the transmitter.

You just compared a learning thermostat to a programmable thermostat. That leads me to this question:
Nest $249
Oranges $1.29/pound
So who is more expensive?
You are confusing the "lameness" of the patent with the "lameness" of the feature.
Actually, that one's not quite as ridiculous as it sounds, assuming the technology isn't much different from home thermostats. AFAIK, home thermostats in an old home with only a furnace might have as few as two wires: one that's approximately 24Vac, and one that gets connected to it whenever the furnace should turn on. A newer home with an air conditioner might have two or more additional contacts for the a/c compressor & blower, and possibly 24vac of its own. I believe that most use battery power for the digital logic, but use the 24vac to energize the relay coils. I believe most home digital thermostats were historically battery-powered because the logic doesn't draw much power, and because it prevented the programming from getting lost whenever the power were shut off at the breaker.
Fast forward to 2012. For literally a few cents, you can buy an 8-bit microcontroller with real eeprom and flash, and a linear power supply to convert 24vac into 5vdc is far from being rocket science. Instead of relying upon continuous power to keep the settings alive, you can just write them to flash, and read them back when power gets restored. I believe this is more or less the nature of their patent.
Assuming I'm mostly right, this is a pretty lame patent. Unfortunately, it probably does meet the technical standards for being granted. I can only assume that Honeywell grabbed it because the market for home thermostats has traditionally been so small, few other companies have even bothered with it (I mean, let's be honest... how often do most people REALLY replace their thermostats?), so nobody else even thought about filing a patent for it first.
