Are you familiar with that kind of stuff? So maybe you could help me out?
I assume this is what you've found?
Just because it's a US patent, doesn't mean it's not applicable elsewhere. There's no such thing as an international patent. You register your patent in one country (or sometimes, a cooperation block of countries such as the EU), then you are free to register that patent in other territories, usually according to your most important sales markets. Of course, that all costs money, so most manufacturers (especially small ones) will balance potential sales loss against cost. You can check if a product is registered in Europe by using a local German patent office search facility.
Having read the Kelly Shu patent claims, I'd say your product absolutely crosses most of their key features, so establishing what free market areas exist is paramount. Although your feature of being able to mount two mic's is unique to your design, it borrows the fundamentals of the Kelly Shu patent.
