20 years from the first filing, so perhaps as early as 2024?? But I think itāll play out more like the tracksaw market; established manufacturers first, coming in at the same - or slightly lower - price point that Festool have established. Then, years after, we get OK quality copies, before finally after a decade or so we get genuinely useful budget options.
Except of course, saws - even plunge saws - are relatively simple compared with something like a domino.
As
@JobandKnock says above, look at the attempts to copy the duo-doweller - literally two drill bits, all you have to do is make sure that point in the same direction and engineer a halfway-decent fence - but the likes of Triton canāt even manage that after how many years of trying? So, given the relative complexity, engineering-wise, of the Domino I donāt see it working out for the budget makers, certainly not for a while.
