I just designed some logos for my own company. I'm wondering if I can apply a patent for those logos, and put copyrights on them?
Design patents and copyrights are two different methods of protecting intellectual property. My guess is that for company logos copyright is more appropriate.
If its your own logo design, there is no doubt that you want someone else to plagiarise it.
either you go for patent or trademark, I suggest you get it done at your earliest.
