Innovative Dynamics Inc, a US company, filed for a patent for their electro-magnetic expulsion de-icing system over 25 years ago. The patent, US6102333A, was granted in 2000. The systems are built in the US by Cox and Co for a variety of aircraft, not the least of which being Boeing's P-8 Poseidon anti-submarine aircraft. Apparently US Navy has no aversion to "Russian technology".
Yes aware of the Cox system, was supposed to be included on some business jets. The Russian EMEDs was first implemented back in the 70's on an IL-74 or 76 and was first fitted to a commercial design on the IL-114 in the 90s for full wing, tail and belly deicing. Unfortunately at the time Russian planes were on the nose, even in Russia as this was just after the collapse of the Soviet union. From what I heard the IL-76 system operated without fault for 70,000 cycles, compare that to a pneumatic rubber boot system....

The 'Russian tech' comment is why SAAB aerospace didn't proceed with it.

EMEDS technology has been around in Russia for years, its used to deice structures like pipelines and buildings.

IL-114-300 looks like it may have needed that system on its first flight....
