Satellite Abandoned Due To Orbital Patent

EreIamJH brings news about a commercial geostationary satellite that was launched last month. Due to a launch failure, the satellite did not reach the orbit required to perform its function. The satellite's owner, SES Americom, looked for a way to salvage the satellite, but ran into an unexpected hurdle; a Boeing patent on the lunar flyby process that would be used to correct the satellite's orbit. If another company doesn't purchase the satellite, it is likely to become another piece of space junk. The European Space Agency has posted a gallery of the maps they have put together for man-made debris in orbit around the earth.

    They are suing Boeing in another matter, Boeing told them they could use the patent if they drop the suit (50 million according to the article). Unlikely Boeing will license them the patent.

    RTFA. There is an unrelated legal dispute between the two companies and Boeing wanted to tie the licensing of the patent to a settlement of that dispute.

    It's worth pointing out that Boeing only denied the request to license the patent because SES Americom is suing them over something else. So really this isn't a case of "patents are evil" it is a case of "you reap what you sow".


    Also, SES Americom has the option of selling the satellite to someone who might be able to get the license from Boeing. However, they have chosen to "splash" the satellite and collect their insurance money.

    Dirty tricks all around by SES Americom, but less so by Boeing.

    Likely jurisdiction would fall under wherever the owner of the satellite is.

    It's basically the same as international waters, it depends on what flag you're flying. The owner is american, and that means the satellite is a tiny part of america. Thus, american patents apply to it.

    Time to again draw attention to us patent 6368227: "A method of swing on a swing is disclosed, in which a user positioned on a standard swing suspended by two chains from a substantially horizontal tree branch induces side to side motion by pulling alternately on one chain and then the other."

  8. here's the lunar flyby trajectory by ChrisCampbell47 · · Score: 5, Informative
    I remember when they pulled off that lunar flyby method to save the satellite. It was May 1998 and the AsiaSat 3 launch had been presumed a complete failure, just like AMC-14 this time. The lunar flyby option uses the satellite's own fuel (instead of a booster) to slowly, over weeks, nudge the satellite's apogee further out until it reached the moon's orbit. It flew by the moon as the moon itself was flying around the earth, and the result was that the moon's gravity pulled the satellite in the right direction to get it going towards a useful GEO orbit.

    I had that trajectory plot (done with AGI's STK, I think) as the desktop image on my computer for 3 years.

    Here is what the trajectory looked like. The big tradeoff of this method is that you burn most of the satellite's fuel, fuel that was intended to be used over the 15-year life of the sat for stationkeeping. So you end up with a sat in GEO orbit but with much less lifetime. Better than nothing! Well, except for an insurance payout, I guess.

    It isn't. Here's the USPTO page. OMG...

    Patent Granted: Tarzan Swinging

    Lastly, it should be noted that because pulling alternately on one chain and then the other resembles in some measure the movements one would use to swing from vines in a dense jungle forest, the swinging method of the present invention may be referred to by the present inventor and his sister as "Tarzan" swinging. The user may even choose to produce a Tarzan-type yell while swinging in the manner described, which more accurately replicates swinging on vines in a dense jungle forest. Actual jungle forestry is not required.

    Licenses are available from the inventor upon request.

    Mod parent down. I just looked at the links provided by another poster in this thread, and realized I misread the description of this "lunar flyby" maneuver. It isn't just a resonance, it's an orbital transfer that literally involves a close pass by the moon. The maneuver is useful (I think) to regularize orbits that are both very eccentric and have high inclinations. A high eccentricity orbit can have its apogee (farthest point on the orbit) shifted with little delta-V required if the rocket burn is applied at perigee (closest point to earth along orbit). By doing this, the apogee can be shifted close to the moon, and lunar gravity can very efficiently (compared to a brute force burn) shift the inclination of the orbit.

    New ideas get shared because they are very hard to keep secret.


    And that, my liege, is why patents were not meant to apply to ideas but to actual inventions.
    Having the idea that some elastic stuff would come really handy, but that's just an idea that anyone can come up with. But, on the other hand, the process of vulcanization is an entirely different beast: it can be kept a secret rather effectively and it really takes some hard work (or huge luck) to come up with that.
