Toyota Prius Under Fire For Patent Infringement

tekiegreg writes "According to Auto Service World, Toyota (and possibly other hybrid companies) are guilty of violating a patent with their Prius hybrid Systems. The patent in particular looks like it covers most of how the drive-train and even the braking system of a Toyota Prius functions. The implications of which are big if there is no deal or settlement made (such as ceasing of hybrid vehicles in the United States)."

    Man, people who deliberately use "submarine patents" to try and make money off a popular technology really bug me. As do "technology companies" whose sole business model is to own patents. They wait and see, and if the tech becomes successful, they pounce. If it flops they stay away and let the infringer take the loss.

    I respect the rights of patent owners, and I'm not sure how you could legally sanction this berhaviour without harming patent holders' legitimate rights, but the practice is just plain sleazy.

    Now it may be that they have had suit against Toyota ever since the hybrid came on the market, and this is just a recent expansion of that suit, in which case they are not being weasels...

    It also expires in three years.

    This actually looks like a reasonable patent -- the inventor did come up with a reasonably novel approach to getting decent efficiency out of electric motors under varying load conditions, and published it via the patent system long ago.

    The auto companies pay plenty in patent royalties every year, and if they'd negotiated terms before using this (which may well be tracable to their designs) then I doubt they'd have had to pay much. They may not have to pay all that much now, hard to say.

    I don't know why you got modded funny. It should be a well know fact (especially to /.ers) that OPEC buys up every alternative energy/locomotion patent it can get its hands on, and then calls it "Research".

    Thank heavens we have those patents to encourage innovation. The invention would never have happened otherwise.

  5. Hybrids aren't that big a deal. by MaWeiTao · · Score: 4, Insightful

    I'm all for innovation, enhanced fuel efficiency, alternative fuels and all that. However, I have a fundamental problem with hybrids. Hybrids are an overly complex method for squeezing out a little extra mileage.

    There are two reasons why they've been attractive. The first is that they're fashionable, especially with the celebrities driving around in them. But even then, the Prius has been more successful than any other hybrid not because it's superior, but simply because the styling is different from most cars. It looks futuristic, it looks like a hybrid. the car is essentially a fashion statement.

    The second, less perceptable reason for your average consumer, is that hybrids don't feel like they're equipped with a small gasoline engine. The fuel efficiency all comes from the fact that the engine is small, not that there's some great leap in technology in the car. The distinction is that the electric motor provides additional power preventing the car from feeling too sluggish. In some cases the electric motor can motivate the car on it's own, but that only applies to the Prius and Ford hybrids, the Civic still needs the engine to get it going. It's only under a limited set of circumstances that the engine can fully take over anyway.

    Then there's the premium a hybrid commands over a normal car, and the fact that the batteries themselves are extremely expensive, and are rated for, at most, 100,000 miles only under ideal circumstances. Then there's the fact that batteries can be highly polluting, both during manufacturing and disposal.

    If you wan't real fuel efficiency buy a car with a 1 liter engine like are available in Europe. The car is going to be extremely sluggish, but it will get you from point A to point B. You can drive it like a normal car and still expect the kind of mileage hybrids struggle to match. If you want to go one up on that, get a small-displacement diesel which get even better mileage. Although, those cars tend to pollute considerably.

    As an interim step I think hybrids are perfectly fine. My concern is that hybrids are going to turn into cash cows for automakers and they're going to get fixated on them neglecting development of far superior technologies.

    What I predict is that the American automakers will go nuts over hybrids like they did over SUVs. By the time they've saturated the market with them and have to offer massive discounts to get them off their lots the foreign automakers will already be introducing new technologies. Man, I'd like to know what kind of idiots are running those companies.
