Amusingly, it does not appear that any cloner actually bought the product
and reverse engineered it.

diy ACA is protected by the last active patent of Pass Labs. Go ahead cloners; make my day. Show me and/or the high end audio community your commercial [maybe more powerful, and/or improved] clones of my baby diamond.

Good luck with the patent thing. Especially after figuring in cost of lawyers.

Bigger blanks versus bigger guns.

(shooting with a checkbook does make cleaner holes, much more "civillainised" than the dark alley)

I beleieve that would be the "amp with active current source". That appears to have been filled in 96 and granted in 98. 15 years ago
But I don't see the association? That is the Aleph Patent

Fortunately for Pass Labs, and FirstWatt, commercial cloners do/did not appear to give a damn about cloning their products. Despite the abundant and overwhelming published technology by Mr. Pass. Even the legitimate cloning of products via their expired patents. I agree with you that patents have their limitations. Win or lose or abandon, patent lawyers always get rich.

A kit of diy ACA is sold to audio DIYers, and thus readily accessible to wannabe commercial cloners. On? or after 1995, the lifetime of US patents begins from the date of filing and continues for the next twenty years.

Antoinel - last patented is what you can see on top of enclosed pic ; that's Aleph CCS

ACA is nowhere near that ; ok - just one/two caps & resistors difference , but that's huge difference
