No, 2/3rds of Cyclone's US patents are expired.

20090223479 is not a patent, just an application. Its Status in the USPTO Public PAIR database is "Abandoned -- Failure to Respond to an Office Action" as of 05-09-2011.

"Clearance volume valves in a heat regenerative engine", application 20070256415, was also abandoned by Cyclone.

The assignment of Cyclone patents to TCA Global Capital was because TCA loaned money to Cyclone and siezed ownership of the patents as collateral.

Here are the U.S. patents taken out by Cyclone.

7,992,386 Waste heat engine Sep 29, 2015 Expired due to failure to pay maintenance fee
7,900,454 Connecting rod journals and crankshaft spider bearing in an engine Apr 28, 2015 Expired due to failure to pay maintenance fee
7,856,823 Pre-heater coil in a heat regenerative engine
7,856,822 Heat regenerative engine
7,798,204 Centrifugal condenser Nov 11, 2014 Expired due to failure to pay maintenance fee
7,784,280 Engine reversing and timing control mechanism in a heat regenerative engine Oct 21, 2014 Expired due to failure to pay maintenance fee
7,730,873 Valve controlled throttle mechanism in a heat regenerative engine Jul 29, 2014 Expired due to failure to pay maintenance fee
7,407,382 Steam generator in a heat regenerative engine Sep 5, 2016 Expired due to failure to pay maintenance fee
7,080,512 Heat regenerative engine

The lapse of the steam generator patent isn't in Google yet. It is listed in the USPTO Public PAIR database, but that doesn't seem to allow direct links.

6 of 9 of Cyclone's U.S. patents have been allowed to lapse for non-payment of fees. Of course, after all these years Cyclone has never been able to demonstrate any of those inventions worked well enough to justify keeping the patents, either.

As for other patents citing Cyclone patents as prior art, that only means some aspect of their patents is similar to some aspect of Cyclone patents. Usually it means they improved on some weakness of the Cyclone patent.
