Back In The Days When Skywriting Was Patented

from the glad-those-days-are-gone dept

Eric Goldman alerts us to the news that, back in the day, skywriting was patented (see patent below) and that there were advertisements warning people not to infringe. This particular ad was published in 1924 in Aviation Magazine.
If you can't read the warning, it states:
Warning: The process of forming Morse or written signals in the air by means of smoke or other visible trails emitted from an aircraft and the apparatus used in connection therewith are covered by Patents issued and pending in America and abroad. Vigorous action will be taken against infringers.
It seems some things just never change.

    They used smoke signals didn't they?

    Wouldn't that have counted as prior art?

    Nope Smoke Signals don't count as prior art, they were not emitted from an Aircraft.

    Today's jets emit a trail caused by the cooling. They would be infringing by spelling a long i. Or a double lowercase l

    Exactly. All this post proves is that what is obvious today wasn't obvious at some point in the past.

    It's a good patent, and in it's day was innovative and unique.

    Re: Native Americans

    But if a group of Native Americans had patented smoke signals in (say) 1921 they could have used it to block the Skywriting Corporation - creating a patent thicket.

    Also I think that the amoke signal prior art would still have invalidated the rider about morse code etc - since that doesn't require the aircraft to manouevre in order to create the message - the aircraft is therefore irrelevant in that case.

    It said that "written signals in the air by means of smoke or other visible trails emitted from an aircraft" then just do not have it come from the aircraft but a tow behind smoke machine. :)

    Re: Re: Native Americans

    No - it was an obvious patent even then.

    I think the idea that "it was not obvious then - even if it is obvious now" is incorrect. The point is that these things are obvious to anyone who has the right background knowledge (and remember the patent test requires the idea to be non-obvious even to someone "skilled in the art" - not just to Joe public).

    This patent is far too broad. A sensible application of the patent process would be to some of the details (eg the method of finding the correct height to do the skywriting - which must have required some thought and effort at the time.

    No - I'm saying that if they could have encapsulated their method for finding the right altitude into a device - then they could have patented the device - it would have been easy to work around - so no thicket.

    It was obvious to Joe public even then. It's only non-obvious before the technology that makes it possible existed. Once airplanes with smoke trails exist, it's obvious. No R&D costs required to think up the idea.

    Aren't patents supposed to be on specific designs, not general ideas? I can sit around and come up with ideas all day long, why should someone a patent on every idea that anyone can possibly come up with? Ridiculous.

    Re: Re: Re: Re: Native Americans

    Here is a website that explains it a little better

    http://ideas.4brad.com/archives/000061.html

    The problem is that the ability to create smoke trails was a new problem that arises with the advent of Airplanes. New solutions to new problems make for bad patents. A better patent would be if someone found a new solution to an old problem after many years were given to solve that problem. The question that should be asked is, how long has something been a problem and how long have people been looking for a solution. Smoke trails is a relatively new problem because the technology that enables them is new. Now, having a patent on an airplane maybe a different issue, but the airplane example itself is another example of how patents are harmful to innovation (ie: the wright brothers delaying advancement resulting in other countries advancing before us until the government decided to step in and prevent patents from delaying advancement).

    Overall, though, I tend to be mostly against patents, I think they're just another abuse that only hinder innovation and invention and serve to create more income inequality and lost jobs.

    Re: Re: Re: Re: Re: Native Americans

    I think the question that should be asked here is, would contrail signals likely have been invented if it weren't for patents? I think the answer is yes, so a patent shouldn't have been granted on it. If patents are to exist they should only be on things that wouldn't otherwise exist.

    Accidental infringement

    So you the engine of the airplane billowing out smoke as it fails constitute a patent violation?

    I mean, smoke pouring from your airplane engine is clearly saying "Help", "I'm crashing", or "Oops! Forgot the oil again.", so it is sending a message via smoke from an aircraft.

    Innovative in the sense of "hey look at that isn't that neat" (unpatentable) not in the sense of "solves a legitimate technical problem that would have been unlikely to get a solution if we didn't have a system that grants temporary monopolies on such solutions"

    It's a good thing that The Skywriting Corporation of America was issued that patent because it initiated an avalanche of innovation in the field of skywriting from which we have all benefited immensely. I don't know where we would be today if it weren't for this patent.

    It puts infringers on notice which is required. Please leave these matters to those who understand it.
