Patents can be found invalid for many reasons.
I remember a case where a guy had patented swiveling handgrips for a
wheelbarrow. Somehow the patent ended up inadvertantly giving him a
patent on the whole wheelbarrow. It was struck down in a court case,
and he lost his patent. I'm not sure if he was ever able to resubmit
for a new patent for just the handgrips. It's not a quick or cheap
His patent may not be quite as "Locked up" as you think.
Besides, a patent merely gives you standing to sue. It's still up to
you to defend your own patent at your own expense. You can't just call
the cops and make a complaint. If you lack the financial means to
initiate and fight lawsuits, your patent won't do you ANY good.
I'll bet Ryobi or Dewalt have a lot more resources than this guy. One
of them might decide to produce a saw with the same feature done
differently, and go in understanding he might sue them. The little guy
occasionally wins those sorts of battles, but it's rare.
Well that makes me feel better. I had come up with The World's Best
Idea one night in a bar and wanted to patent it, and the next morning
I couldn't remember The Idea. Glad to know I didn't really lose
I worked for a large multinational for *many* years on a very active
patent review board (we reviewed around 200 patents a year). How many
patents do you hold?
Absolutely false. The has the patent on a sensor connected to a saw
blade detecting a human limb activating a blade brake. *ANY* sensor
that detects human contact with the blade and activates *ANY* sort of
blade brake falls under this patent. That's a pretty damned broad
concept. Have you even read the subject patent?
I understand enough to know that patents can be gotten around. I know that
patents don't stop others from doing as they please. I know a company that
filed suit against about a dozen companies for infringing on his patent.
After 6 years, all he has to show so far is a big stack of lawyer bills.
Just because you are not clever enough to get around it does not mean that
some smart guy working in his basement will not. Sorry, but that's the way
it is. As I said, we'll talk again in a few years to see the status.
Of course they will defend it, just as the example I gave. Years later, the
"infringers" are doing business as usual, the patent holder is paying lawyer
fees and has recovered nothing, stopped nothing. Only winner so far is the
Your small minded opinion. The future is not over yet. Lets talk later.
Some patents are rock solid. Bonney tools invented the flank drive
box wrench and had a lock on it for the patent's entirety. The patent
has since expired and now everybody and their dog makes some version
of it. When the patent was valid, Bonney had such a lock on it, most
ppl didn't even know flank drive existed.
OK one out of how many? Sure some survive, as they should, but others often
are out foxed at some point. Do you have statistics on how many are never
challenged. I know a guy that have five rock solid patents too. He's never
made a single item, neither has anyone else. But he has the patent.
I've seen those. Had an acquaintance who patented the dumbest travel
grill ever conceived, a collapsable 5 sided "portable" grill made with
1/4" steel plate!! We tried to warn him off, to no avail. I think
the patent cost him close to $5K and never a one was made. It was
hilarious cuz the damn thing was too stupid for anyone to even use,
let alone copy.
On the other hand, some good ideas DON'T get patented.
On the other hand, I once took a program I'd written to the VP of
Development (a program for resolving miss-ties in gravity surveys). He said
"This is too good to patent. We'll have to treat it as a trade secret."
I'm sure the sensing mechanism is pretty basic. Instant touch sensing
switches have been around for years. I think the real patent is on
the complex electro-mechanical circuit and mechanism that jams that
alum block into the blade before it can do any real damage. The
design of a mechanism that reacts so quickly is surely innovative and
worthy of a patent.
re: "The price premium is high - now. It'll come down."
When? Here's a thread from 2003 in which lot's of people are
complaining about the price.
I believe the device hit the market right around then. Since that
time, to my knowledge not one manuafacturer has adopted (and paid for)
As long as only one company controls the patent, then I don't see why
the price would come down.
Because the inventor is either a smart businessman, or he has good
people running it. He's been trying to squeeze the market into buying
them at his price by trying to get legislation passed. With most
inventions there's essentially zero chance that that will happen, but
with something that has such great whiz bang demonstrations, and with
something that is obviously so much safer, it's probably just a
question of time. It's a game of chicken.
I didn't say the price would come down overnight, but it will, and I
don't think it will be all that much longer. More money is made
selling lots of units at a lower price than a few at an exorbitant
price. The margin won't be as great, but the total income will be far
more. The most likely scenario is he'll sell the company to a big
manufacturer that is willing to take the risk and pay up front to get
a jump on the competition.
