I came across a website that uses the laser warning sign:

Is it even allowed to use such signs as a logo, or are these copyrighted somewhere?

    Any issues would be regulatory, nothing to do with intellectual property.

    You can ask ISO by sending an email to the address found at this url: iso.org/complaints.html

  • nerdist.com uses an eight-point, all-red version in their logo, so a modified version is probably going to be fine. Jan 26, 2018 at 18:29

    @JoeMcMahon: And similarly the laser warning in red on white has been the logo of the Laser sailboat for many many decades now. eg: laserperformanceunited.com Jan 26, 2018 at 21:20

The warning symbol is part of the ISO 7010 standard as such its normative in many countries. This standard relies on ISO 3864-1, and ISO 3864-3 for further information about colors and sizes of borders etc.

This probably means at minimum that you lose the unique ability to trademark that symbol. Also while you may in some locales have a copyright on the electronic document you created you will not be able to get others to stop from drawing the same thing again. But most likely you have no copyright.

In this specific case the symbol is ISO 7010-W004. And described as:

Circle with 24 regular equally spaced radiating lines, 12 shorter of equal length, 11 longer of equal length and one longer reaching horizontally the right-hand side of the triangle

Note the standard does have images for illustrative purposes and many signs use the exact images*. However please be aware that, to my knowledge, the warning signs do not require you to have the exact same design to qualify just fulfill the text in the description field. To this end iso says:

However some degree of graphical modification is permitted when cultural differences or special application formats need to be considered, provided the original meaning is retained and comprehension of the safety sign is maintained.

THis in turn means its extremely unlikely to win any plagiarisation claim in court. More likely your plagiaraising ISO. Because people can just claim to have followed the description in the standard, which is what its intended for.

* ISO claims copyright on them but gives permission to copy them as is (page 1 of ISO 7010:2011).

    The normative part may be very relevant. There was some discussion here recently when a political party used street signage on their posters. While using a laser warning sign on an arbitrary poster would probably not be an issue, I imagine a logo with the EX warning sign could be an issue when used on devices … Jan 26, 2018 at 12:24

    Funny that the example image doesn't match the symbol description. The example image has 16 lines, where the description mentions it should be 24.

    @Ideogram Step 1) Find a device with this logo, step 2) Make eye contact with the laser, step 3) sue manufacturer. Pure profit.

    Do not sue manufacturer with remaining eye... Jan 27, 2018 at 2:34

    @JohnDvorak ref here google.com/…: Jan 27, 2018 at 8:30

I would say you might be able to hold it as a trademark in your niche (you better not make lasers or laser accessories, because you could never hold the trademark there).

So for instance if you formed Remaining Eye Records which mostly focuses on EDM... and all your LP centers had a stylized version of that logo... And you got established and known in the industry... And Straight Records tries to use the same logo, no problem getting a "knock it off" order even if Straight Records is a classical label.

But if Ruby Red Jewelry used the same logo, you'd have to strongly show that customer confusion is likely owing to targeting the same demographic, sold in the same shops, etc.

Couldn't touch the Laser sailboat or Ford Lightwave.

Nonetheless, this is a bad idea precisely because it's so un-unique qnd obvious: you are going to have collisions like this. How do you know you aren't Straight Records, arriving second to the party? How do you head off Ruby Red Jewelry's before they happen?

And ISO might have some concern with you "diluting their mark" - like happened with the skull and crossbones poison-warning label. So when they copyrighted Mr. Yuk, they decided to defend it strongly so a soft-drink maker doesn't use it.

But the laser mark is to protect people working with lasers, which isn't everyone. Similarly you see a lot of the nuclear mark used ironically. So a judge may not agree with their concerns of mark dilution.
