Ali and other e-commerce need to follow the local (destination country) rules in patents and copyrights. Some big companies (for example, one that is selling child toys from peppa pig cartoon) have only dealer in one country or region. Any other sellers (resellers) of same (or counterfeit) goods recieve court invitation soon after they were caught. They have different ways to clean market from copies - special employees who walk through local shop and making photos, special documents for customs (import customs for EU and export customs for China, BTW export permission for few countries which do not worry about copyrights is very common for China), sometimes they even ready to buy a pilot batch to find out and judge manufacture.
But as far as chinese sellers (ali) have their own problems (shipping), the most easy and effective way is communication with platform itself. Ali should hide all brand items and easy recognizable clones from the search, or next barge with goods will pass through all inspections that you can imagine and it will take 60-90 extra days.

P.S. Once I found a video with some unique machinary techinics. Machined part had a little relation with weapons, and youtube hide it in search for all countries because of one of the US laws. So you can carry a weapon, but not allowed to see some technics about its accessories made. Whats next? You can eat food, but not allowed to see how it is made if you dont have a cooking PhD?
