Patents do work, but only if they are enforced now good luck having that happen in China however enforcing them in the US/EU will be the best place to for Maxspect to draw their line in the sand, assuming there actually are patent violations. Although with the way of the internet you can just as easily buy them online from overseas without having to deal with a US supplier (who would be liable for selling anything that infringes on a patent).
Its hard to feel sorry for companies though, it's no secret in many cases they simply use the same suppliers/machinery to make the copies as they do they real thing, such is the problem with outsourcing your manufacturing to a country which is well known for counterfeit goods. You want the cheapest manufacturing price you can get? Or do you want to not have your product copied (as easily).
And FYI, you do need to file patents in every country you want to have any sort of enforcement.
