Patent Claim Could Block Import of Toyota's Hybrid Cars
JynxMe writes "Paice is a tiny Florida company that has patented a way to apply force to a car's wheels from an electric motor or internal combustion engine. Paice thinks that Toyota is infringing on its technology, and is going after the automaker in court. The legal spat became much more serious for Toyota this week, when the US International Trade Commission decided to investigate the matter. In the worst-case scenario for Toyota, the commission could ban the hybrid Camry, third-generation Prius, Lexus HS250h sedan and Lexus RX450h SUV."
Now that's a productive way to encourage Electric hybrids! WTF is wrong with these morons.
The filing date is May 8, 2006. Really? This technology wasn't around before then?
Typically Toyota uses the US market to drive design improvements that they want to make and can't pay for at home via high profit margin specialty items. This is why they created the EV RAV4 way back in 1994 and the first round of PRIUS sedans when California backed off the polution requirements. Those early models were a way to pay the designers and engineers to improve the technology and get smarter without loosing buckets of money. Currently they are packing high demand US cars with extras like navigation (and solar panels starting next year) to increase the volume of the technology they want to use elsewhere on other things to drive down costs. Great smart marketing and management by them when they sucker us into paying high prices for these extras but we want the cars so we pay up and they make a lot of extra profit.......
Honda has been doing the same thing with engine technology in other products like race cars, snow blowers, ATVs and motor cycles for years. The technology and design features discovered and the factories built for one product pays for the design improvements in other places like great small cars......
C'est la vie.....
*giggle* Couldn't they argue the patent validity based on PRIUS use?

They patented the transmission, exactly. The use of a planetary gearbox to sum the output of the gasoline and electric motors, or to have the gasoline motor drive the generator. I share the antipathy for software patents with most of the Slashdot crowd, but this is a classic hardware patent. Hardware patents have a long and important history, and are almost certainly a good thing.
Curiously, GM's Volt doesn't violate this patent, as it is a so-called "series hybrid", in that the gas motor only drives the generator, and the wheels are only driven by the electric motor. The Ford Fusion and Escape hybrids, and the Nissan Altima hybrid use exactly the same system that Toyota does, licensed from Toyota.
Toyota has made the system useful (in a way that the original patent isn't) by adding a second electric motor which assists in driving the wheels directly. This enables a "low gear", by having the gas motor run fast, driving the first motor/generator backwards to generate power, which drives the second electric motor. That is the decisive conceptual leap in the Synergy drive, and Toyota has of course patented that.

I love Mondays. On a Monday, anything is possible.
Contrary to oft-repeated headlines, a patent-holder never wants to block a patent-using technology from the market. They just want to get paid for it. If, indeed, the patent is valid — and the size of the patent-holder is no indication either way — Toyota simply needs to pay for the technology...
The article write-up seems like it is written by a Toyota-shill. If a Paice-shill were to write it, it could've been rephrased along the following lines:
In Soviet Washington the swamp drains you.
"The US is not the market for Toyota it once was. The reasons for selling into the US are declining with each passing year and Prius are showing up on used lots in increasing numbers"

I fail to understand this as Toyota outsells GM worldwide, and is within a few points in the US. Perhaps you're just seeing more Priuses (Priusi?) on used car lots because dealers are stocking what people want, and cash for clunkers took a lot of US cars out of the used car market?
The KBB of an 8 year old Prius is still around $10k. So, um... dunno what you're saying.
Interesting that a company located in Florida would choose to sue a Japanese company in the seemingly random location of Marshall, Texas.

Yes and the Toyota Prius has been around since err
1997.
(http://en.wikipedia.org/wiki/Prius)
and it was sold worldwide since 2001 (I'm assuming that includes the US).
If the US had technology companies run by engineers and technical people rather than lawyers and accountants perhaps they would chose
"innovation" over "litigation" as a business strategy.
The sad truth is that even if someone at GM or Ford had the same idea in 1997 or earlier the bean counters and lawyers would have axed a hybrid in favour of more profitable SUVs..
If you don't believe me look at who's on the board at GM, do a search for engineer in this article: (http://www.finchannel.com/news_flash/Oil_&_Auto/43476_New_Slate_of_GM_Board_of_Directors_Members_Selected_/)
funny... almost no engineers...

4 out of 5 on the management board have engineering backgrounds..
Hmmm.
Stealing US ideas... what ideas? The idea to sue everybody... maybe I should patent "patent troll law suits" and sue all the patent lawyers (after all it is a "business process" and a "unique" invention)...
----- "Profanity is the one language that all programmers understand."
Given that the patent application was filed May 8, 2006 is seems that Toyota's hybrid easily predates (circa 1997) the patent.
The patent claims start, "1. A hybrid vehicle, comprising: at least two pairs of wheels, each pair of wheels operable to receive power to propel said hybrid vehicle;..." No later claim seems to remove the requirement that power is deliverable to all pair of wheels. Does a Prius drive all four wheels?
Patent litigation: A doctrine of Mutually Assured Destruction... in which everyone seems willing to push the button
Thank Vulcan for Paice, without whose invention we would never have hybrid or electric cars. Without the Patent Office creating their monopoly, which has never produced a car, people freely speaking about how to make electric and hybrid cars would be getting us off internal combustion. And that's bad for America.

The first generation Prius was sold only in Japan, but it went on sale in December 1997.
Do what thou wilt shall be the whole of the Law
But the question remains why the case was awarded against them - as post #29686903 points out, the patent the Prius supposedly infringes against is based on a patent that has recognized the Prius. Plus, the first patent was filed after the Prius entered mass production. That doesn't quite support the idea of Toyota stealing the tech unless Paice took extremely long to get that patent filed after disclosing its contents to Toyota.
