This is just for my curiosity and education. I see that there is a trademark filed with USPTO for the name Cassandra. There is also a very popular database by the same name. Then is using this name for the latter not a violation?

The trademark registration you linked to is for use in "women's intimate apparel, namely bras, panties, garters and chemises."

To name a database product "Cassandra" is not likely to cause any confusion with use in the context of women's intimate apparel.

See Trademark Basics: Scope of Protection.

There are even other "Cassandra" marks registered:

    That's why Disney trademarked "Mickey Mouse" in over 70 fields. Even though it's not copyrighted anymore, you're still going to get C&D letters from them. Jan 4 at 12:44

    Note: the Apache one in your last example is almost certainly the "very popular database" the OP is inquiring about. Jan 4 at 13:22

    @MindwinRememberMonica Most Mickey Mouse cartoons are still copyrighted. The only thing that entered the public domain was the very first cartoon, Steamboat Willie.

  • The character did, too. And that's the most important thing. @Barmar . That the other cartoons are still copyrighted is only ancillary to the main issue. Unless you are using some feature or OTHER characters that appeared in the most recent cartoons, your statement is a red herring. Jan 5 at 13:22
  • @MindwinRememberMonica But MM's design has changed over time. So versions that are portrayed differently are not PD yet. See this question

Trademark is limited to a particular class of goods and services, and does not grant complete business ownership of a word. The item of which you speak is for "women's intimate apparel, namely bras, panties, garters and chemises", therefore a software usage does not conflict with that trademark.
