No. But I am capable of reading

A patent shall be presumed valid. Each claim of a patent (whether in independent, dependent, or multiple dependent form) shall be presumed valid independently of the validity of other claims; dependent or multiple dependent claims shall be presumed valid even though dependent upon an invalid claim.

The claims narrow the scope. Claim 1 is "A retail paper bag, comprising: a bag container formed of white paper with at least 60% post-consumer content".

Claim 4 is the narrower claim of "A retail paper bag, comprising: a bag container formed of white paper with at least 60% post-consumer content comprising a reinforcement insert adhered to an interior of the bag container"

Claim 5 is the even narrower claim of "A retail paper bag, comprising: a bag container formed of white paper with at least 60% post-consumer content comprising a reinforcement insert adhered to an interior of the bag container, wherein the reinforcement insert is adhered across a fold of the bag container"

So while the broad claim may not be valid, a dependant claim of narrower scope may well be. This is not about whether a product infringes. In this case, a product can't infringe claim 5 without also infringing claims 4 and 1. But if claims 1 and 4 are shown to be invalid due to obviousness, 5 is not.

Why would they add an oxygen tank? There's oxygen in the air!

A hydrogen fuel tank exploding will be quite a fireball, for sure, but hydrogen tanks are pretty tough. And even if they do explode, there's only so much energy stored. Not enough to affect anything that hasn't already been affected by a train barelling into it.

It does strike me as inconvenient. Per MJ, methane at 250 bar takes up as much space as hydrogen at 700 bar, and many other hydrocarbons are liquid at room temperature. Plus natural gas already has a distribution network installed. Plus it already exists as a chemical in nature; so that's zero reactions.

I guess the inherent efficiency of hydrogen fuel cells makes up for all the other costs. Fuel cells do have excellent efficiency.

Very little commercial hydrogen comes from water. It's cheaper to get it from natural gas. Problem remains (You'll be better off using the methane to power a power station), but I think it's important to be aware of this if we're discussing the relative benefits. .

These trains are designed for low volume routes where catenary would be expensive. Still, I'd have thought there are more convenient fuel sources. Hydrogen has excellent energy density by mass, but it's terrible by volume. Presumably hydrogen is just best for fuel cells.

Doubt that will have much of an effect.

I think only the hardcore gamers will be upgrading from their existing PS4/XBOnes. Others may see this as a justification to own both systems. PS3 and XB360 owners don't have a huge justification for sticking to the same brand, except brand loyalty, since the new systems aren't compatible.

That's not how it works at all.

Claim 5 is "A retail paper bag, comprising: a bag container formed of white paper with at least 60% post-consumer content comprising a reinforcement insert adhered to an interior of the bag container, wherein the reinforcement insert is adhered across a fold of the bag container"

If claims 1 to 4 are invalid, but you also have a reinforcement insert adhered across a fold of the bag container, then you are infringing claim 5. The only time claim 1 will come in here is if your product is not a bag formed of at least 60% post-consumer content.

For a patent to be valid, each and every independent claim must stand on its own, with no support.

Nope. Completely wrong. For a patent to be invalid, all of those claims must by invalid. Claim 2 is a completely different invention from claim 1. If an invention violated claim 17 and no other it infringes the patent

The paper bag in claim 1 is the paper bag as described in the description. The claim doesn't go into description because it is just explaining what the patent claims. That is; it claims the white paper bag described in the description.

Comment Re:What the actual fuck (Score 1) 201

They didn't patent a paper bag. They did patent a specific design to make a paper bag with increased strength. The patent is not on using paper to make a bag. This is not how patents work. Patents protect specific techniques. This is what the patent is protecting.

Comment Re:3COM robots are 3-laws safe! (Score 1) 68

Those laws are a nice idea for fiction, but for reality they're wrong.

The first law has the "or through inaction" rule which means that the robot would rarely do what you want it to do because it would be constantly rushing around saving lives.

The second and third law are the wrong way round. If I instruct my expensive robot car to jump off a cliff, I prefer it to get to the edge of the cliff and stop. Most hardware has built in limitations of this type. For example, my car has a rev limiter which allows it to ignore my instruction to the engine to potentially damage itself.

It should only obey orders given to it by a specific subset of humans. If I send my robot out to the shops, I don't want everyone else borrowing it to do their odd jobs.
