Patents The Courts Technology

SpaceX's Challenge Against Blue Origins' Patent Fails To Take Off 61

speedplane writes As was previously discussed on Slashdot, back in September SpaceX challenged a patent owned by Blue Origin. The technology concerned landing rockets at sea. Yesterday, the judges in the case issued their opinion stating that they are unable to initiate review of the patent on the grounds brought by SpaceX. Although at first glance this would appear to be a Blue Origin win, looking closer, the judges explained that Blue Origin's patent lacks sufficient disclosure, effectively stating that the patent is invalid, but not on the specific grounds brought by SpaceX: "Because claim 14 lacks adequate structural support for some of the means-plus-function limitations, it is not amenable to construction. And without ascertaining the breadth of claim 14, we cannot undertake the necessary factual inquiry for evaluating obviousness with respect to differences between the claimed subject matter and the prior art." If SpaceX wants to move forward against Blue Origin, this opinion bodes well for them, but they will need to take their case in front of a different court.

  • How is the patent enforceable in international waters? Federal courts have ruled they aren't in other lawsuits.

    I'm genuinely curious.

      Presumably to do the method described in the patent, it would need to be implemented in the technology. This technology needs to be created and built somewhere. So although I'm guessing they couldn't enforce it during the landing, they could try and enforce it during development, construction, etc
      But I'm not a lawyer.

      Why is it again they want to land on a platform at sea instead of back on the ground?

      Plenty of open space in South Texas.

        Space launches tend to go east in order to pick up the Earth's spin to reduce the speed needed by that amount. Therefore, when launching from Canaveral (or that newfangled launch pad in Virginia Beach), a sea landing is the only logical choice.

          Furthermore, that is why rockets launch from the east coast in the first place: if something goes wrong, the flaming debris comes down over the sea.

          However, SpaceX are aiming to do a return to launch site for recovering their stage I boosters. (This surprised me - this must use more fuel than land-at-sea, and the mass of that fuel is directly subtracted from your available stage II payload.) The landing at sea is an interim measure while they prove the technology (because of the afore mentioned potential for flaming debris.)

          • I've heard that, long term, there are two alternate plans, depending on the percentage of payload/delta-V being used: if the target orbit requires enough of the total capacity to make returning to the launch site infeasible, it will instead land on the floating barge to refuel, and *then* fly back to the launch site.

            I suspect that landing at sea, while less energy intensive, is considerably more difficult - especially considering that you now need favorable weather at both the launch and landing sites to ha

            • gosh, it'd be rather un-aerodynamic without the nose-cone. I rather suspect they'll wait to deorbit until the timing is right for the desired landing zone.

              Unless there's a crazy-orbit launch with no good rendezvous, in which case landing on a barge is still going to be much cheaper than building a new rocket by an order of magnitude. This is good enough reason to proceed with clearing the patent. That and spanking BO's deserving ass.

                The first stage is suborbital, so that's not really an option. And when it comes to aerodynamics, on the way up it's pushing hypersonic speeds with a not-even-supersonic-friendly profile, not even the usual "nose-needle" to break the shockwave, presumably because it's having to fight gravity the whole way without lift surfaces, so can't face directly into the line of motion. Plus with the fact that it doesn't start really pouring on the speed until it's mostly clear of the atmosphere anyway.

                Bottom line - it's a rocket: with minimal lift surfaces efficiency isn't really high on it's feature list to begin with. On the return trip it's free to travel at much lower speeds though - it's basically a tradeoff between air resistance and the fuel consumed to hold it in the air instead of falling like a rock. Still, fuel is currently only a couple percent of the total cost of a launch, so even if you had to double the amount used you'd still see negligible effect on the total launch cost. First they have to get rocket reuse working - once you can get a half-doze uses out of a rocket, then maybe it makes sense to start worrying about efficiency on the return trip.

                • The first stage is suborbital, so that's not really an option.

                  Yes, you're right of course. I must've been thinking Dragon v2 rather than the first stage burnback. durr.

                  Interesting - kerosene may well be cheaper than shipping a rocket across an ocean.

                  • I suspect a bigger issue is protection from sea spray and the lateral stresses of crossing hundreds of miles of open ocean, neither of which can be healthy for a rocket. Either they have to secure the 13-storey rocket on the landing barge (or a cargo vessel) to get to land, then transfer it to a vehicle capable of carrying it overland to the refurbishing site (the largest military cargo helicopters could *just* carry it, but only have a range of a few hundred miles), or they fly it home under it's own powe

          The ultimate goal is for the rockets to get back to landing pads near their launch pad, including their launches from Florida. They're only landing at sea right now because they need to demonstrate a consistent track record before the interested parties will let them attempt a return-to-launch-site landing. They've got various approval processes going on to build landing sites at Kennedy Space Centre. Based on where the Falcon 9 staging happens, it doesn't take that much more fuel to return to the original launch site versus an offshore ship.

          That's not to say that all their effort into the drone ships is wasted. Apart from the obvious need to demonstrate safe landings on hard surfaces before doing it on actual land, there are some circumstances in which they'll not be able to return to the launch site. Very heavy payloads that eat into their reusability fuel budget, for example. Another is the center core of the Falcon Heavy: it separates much later than the two side cores of the rocket, which means that by the time it separates it's going much faster and is much farther away. Those will always have to land at sea. There are rumours, however, that SpaceX has plans to refuel the rockets on the drone ship after they've landed and then fly them back to the launch site propulsively.

        Not nearly as much open space as there is in the pacific ocean. I imagine a rocket crashing in San Antonio would cause some concerns.

      • SpaceX is not allowed by the FAA (and I assume NASA/USAF have something to say as well) to to perform landings on land until they can prove that the system works reliably, so the way around that is use the barge. I believe they are already prepping a landing pad in Cape Canaveral and eventually they will likely land back to their launch site in Texas once completed. I would say 2016 is an optimistic date to see a land-landing if they get a few landed on the barge this year.
        • by Teancum ( 67324 )

          SpaceX keep changing their mind, it seems, as to if they will continue to use the barge after they get FAA-AST clearance to land on the landing pad at KSC. It appears as though they want to keep the option available for either super heavy launches that push the fuel envelope, like what can happen with the GEO launch that just happened, or for trying to recover the Falcon Heavy central core (which will be quite far down range when it finally does stage separation).

          For many launches though, they do plan on e

      • Too bad if you happen to lane in North Mexico.
    • Because the companies involved are not in international waters...?

    • Simple, America owns the world. Sure there have been rejections in the past. But how many were from first class citiz^h^h^h^horporations? Likely those are just second class idiots with no real rights. Or they plan on landing inside Territory belonging to a country with valid patent laws and existing IP. I'm not sure which is more reasonable to be honest.

  • How can a dodgy subordinate claim invalidate the rest of the patent? If it was that easy there'd be a ton of software patents that could be tossed out en masse.

  • I knew the patent system was horribly broken but this is obscene. Perhaps I'll patent "Utilizing a multi-wheeled conveyance to traverse a network of engineered level surfaces to traverse from an origination point to a destination point". This patent doesn't seem to cover any real technology but the general idea of "launching from a land site and landing on an ocean platform".

      • by Teancum ( 67324 )

        In fairness to Blue Origin, the "Do X" happens to be "Make a rocket launch, rise up to a substantial height, and bring the rocket safely back to the Earth in one piece".

        Blue Origin has done that, although the "great height" is debatable. Their New Shepherd test flight is impressive engineering, although watching the Falcon 9 test article fly in Texas is IMHO far more impressive.

  • So, Blue Origin just decided one day; "Hey wouldn't it be cool if we could land space ships at sea?" and went ahead and patented the idea without the foggiest notion of how this might realistically be accomplished?

    And now there's a patent that provides the "what" but absolutely no detail about the "how" one might go about doing this?

    I think we need to take a lesson from the past: bring back the law where before a patent may be filed it must first be backed by a valid working prototype. That should fix all

      Nah, they most likely just read about how to do it. [aiaa.org]
