I'm not claiming any of those apply here. <br>
<br>
The main patentable concepts that Moog seems to be claiming are the use of preloaded control voltages and the sequencing of them to generate a waveform. While this seems somewhat novel to have within a VCO, I'd note that the same concepts are used in multistage looping envelope generators (AR, ADSR, AHDSR, etc). <br>

<pre class="k9mail">It seems you can patent more or less anything in the USA. The test comes not when the patent office grant you the patent, but when you try and defend it in court.

As Dan said, PWM and MCU control and so on are already existing elements, so if someone can show some “prior art”, then Moog can’t claim that was their idea.
