I want to copy the exterior look of an electronic device designed and marketed in the 1950
I would have thought it unlikely they would continue to renew or be allowed to renew any patents/copyrights.
Does anyone have any advice on how to find out whether they would have a claim against me if I wholesale copied the look of this old product?
How long do trademarks last...
...for on the look of a product?
It makes sense, manners cost nothing.
The look of a product is not subject to copyright.
