I want to copy the exterior look of an electronic device designed and marketed in the 1950s for a commercial project.
Given that this was 60+ years ago, will there be any legal barriers to this?
I’ve done some research on the company that released the product in question. They have been bought out/merged several times. The subsidiaries involved are mostly long defunct but part of one is still owned by a massive conglomerate.
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? As far as I can tell, it was never remade or re-issued and wasn’t hugely popular in the first place so I would have thought it unlikely they would continue to renew or be allowed to renew any patents/copyrights.
Any help is much appreciated.
