Betty Boop in copyright and trademark
"What I take from the judge’s ruling is that the trademark only applies to new, modern uses of the character. It can’t be used to stop people from redistributing old PD Betty images/items. Fleischer tried to say trademark trumped copyright; the judge is saying that it doesn’t."
"This is actually pretty major. In recent years, Warner has used the active trademarks on Looney Tunes characters to quash third parties’ reissues of PD 1930s/40s Looney Tunes content (of which there is a lot). If the Betty decision is not reversed on appeal, then Warner is stripped of its strongest weapon against the public domain."
"It can use the trademark against those who would create new Bugs Bunny items, but not against those who would exploit old PD material that Warner failed to protect."
