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."

    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.

    Interesting that a company located in Florida would choose to sue a Japanese company in the seemingly random location of Marshall, Texas.

    What makes you assume that it will get fixed?

          Because I'm a fully qualified, board certified specialist who COULD practice medicine in the US, but refuses to because it's too much hassle. And what's worse is, I'm not the only one. There are many, many physicians who have opted out of medicine and into something less stressful (and potentially disastrous in financial terms). A country that encourages trained specialists to actually work in something less risky because of litigation or even worse, having insurance companies practice medicine by telling doctors what to do and what not to do, is a bit screwed up.

          But then again I forget, this is the US we are talking about. A country that owes the world close to 12 trillion dollars (not counting social security and health care), is printing money like mad, has double digit unemployment (17% if you look at U-6), whose own government admits unavoidable financial armaggeddon, and yet has a stock market that rallies 40% with apparently no end in sight... Yeah, I guess anything could happen.

    I can sympathize with that, about 5 years ago my wife was diagnosed with an incurable but non-debilitating illness, it can and is treated medicinally. I happened to be unemployed at the time after being laid off and cobra had run out...I had been actively looking for work but had to take medicare to get by until I found a job. After I found one, I tried to go from medicare to the same companies paid healthcare and was told my wifes illness was a pre-existing condition (even though it was discovered while covered by the medicare side of the same company) and I havent been able to get her coverage since. In the meantime my bills keep outpacing my ability to pay them and keep a roof over my familes head. IMHO thats broken.
