Analyze US case law as well as its legislation related to trade mark parody works, then talk about how it should be improved and also redefine what kinds of parody works should be protected.

The general idea about this topic would be:

1.Hong Kong has very few case law about trade mark parody.

2. The current legislation(Hong Kong Trade Marks Ordinance) do not provide enough protection to certain parody works. So we could take the US law for reference.
3. Analyze US case law as well as its legislation related to trade mark parody works, then talk about how it should be improved and also redefine what kinds of parody works should be protected. (Is it already enough to protect parody work?)
4. Suggest how the Hong Kong legislation can learn from the US(In full or in part?) how it should expand to protect certain parody work?
