But you all do realize that when you buy the cheap stuff you are rewarding copy cats for stealing the great engineering work of a company right? I don't support price gouging, but a reasonable price to sustain the company for a cutting edge design and quality products is a good thing.
Broad brushstrokes there.
How do you know the Chinese knockoff has infringed on any of Thermoworks' patents? The scope of Thermoworks' claimed invention (i.e., the claims) may have nothing to do with appearance or overall functionality. Quite often, the point of novelty of a product lies in a component, modification or subsystem. It's not terribly hard for someone to design around that patented technology and still end up with a product that is very similar in form and function.
Also, how do you know the relevant patent(s) haven't expired? Thermopens have been around a long time. It's quite likely much of the patented technology has moved into the public domain.
And if there is an infringement, I will guarantee that Thermoworks will act on it. It's not difficult to get an order seizing a shipment once it hits US Customs.
I'm not necessarily defending the knockoffs. And I'm not saying true infringement doesn't happen--it does. But if you are outraged by this, you are in for a frustrated buying experience whenever you want to buy a lot of things in the marketplace. The Chinese are skilled imitators, but the ones who want to stay in business know better than to violate US or international IP laws.
