i'm in the process of starting my own clothing line and have some ideas for designs.Alot of my desings will have well know qoutes, such as:
Can i still have these designs on my shirts, or would i still have to get approval?
"catch 22" is the one that i really want to have on my shirts, but someone told me its not ok, I though that phrase is a public statement, or old saying?
The term "Catch 22" as you know is the title of a book. The copyright protection for a book is the author's lifetime plus 70 years, I believe. I do not think that time has yet run. There are many things that people say, of course, that do not violate copyright law because they are verbal. Copyright law protects things that are put down in some form, e.g., in writing.
The others you mention appear to be generic enough that they probably are not protected nor are they protectable. Catch 22 though is one you should investigate, and see if you can get permission to use it.
