I don't see how the patent could not have expired by now. These speakers were made in the early 80's, and US patents only have a 20 year life maximum lifespan from time of application filing.
Infinity Owners: New EMIM Diaphragms Available
I have a set of these in my RSIIb speakers, and they are a huge improvement over the stock diaphragms in terms of clarity, detail and dynamic range; these are a complete upgrade to every aspect of the EMIM sound. Just released!
Note: I have no association to the seller of these units - I'm just a very happy customer!
