I am planning to write and distribute a pac-man like game. So I would like to know if It is still protected by copyright.
Can I use the word pacman in the title? What are the limits that I will have?
PS. I can conclude from the first answers that I can't use the name and may be a very similar art work. If I keep that in mind, will I have any trouble. And I don't want to do something unethical, is it unethical to write a pac-man like game? I see tons of them on the internet.
It's a matter of trademarks, not copyright. Trademarks don't run out, though they must be continually used. I'm pretty sure Pacman would be considered to be in use, as it's a very well-known brand.
So you'll have to use a different name.
