I don't like the idea of trademarks that are so well-known that they apply in all fields. That doesn't serve the public. Companies that well-known can easily apply for a trademark across multiple fields. The trademark owners that would really need that kind of help are the smaller ones that aren't eligible for that, and must specifically register in various fields of industry.

IP law needs severe reform no matter which jurisdiction you're in (since the majority of the world signed the Berne Convention, the same reforms are needed everywhere)
