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.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.
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Wouldn't that have counted as prior art?

Too bad they had no concept of (intellectual) property

Re: Native Americans
It's a good patent, and in it's day was innovative and unique.

Re: Re: Native Americans
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.

Re: Re: Re: Native Americans
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.

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.

It is still not a good patent.

Re: Native Americans
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.

Somebody in this thread doesn't know what a patent thicket is.

Backwards message?
[ link to this | view in chronology ]
Accidental infringement
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.

Did anyone here tell you that it would be? Did you read the claims of the patents mentioned?
