I hate china and their junk assed products as well. They care little about their people and less about ours. Ethics are nonexistent in China and patents mean little unless you are talking internally I would suppose. But ultimately the Government there will win any contests over patents without a doubt.
This could likely hurt them in other venues as their systems are totally corrupt and they do not really need good litigation skills because the fix is in.
Mounting effective cases elsewhere is going to be hard for them because of this and harder still because they are chronic thieves of just about everything ever produced on some level.
They produce sub standard products routinely. Sheet rock that molds, Light bulbs that cause fires, chemically laden products targeting children to name only a very few of thousands and thousands of products. More care needs to be placed into screening these things at their point of entry. They should just be sent directly back to their place of origin if they are found to be dangerous or sub standard.
