Indeed, trying to pull an "Apple" by stealing others' concepts and seducing
gullible investors is a great idea.
As for the product itself, it's existed for at least the past decade in
various guises - I'm pretty sure Jaycar sold such a pen at one stage, though
I can't seem to find it on their web site now.
Here's an example of one which has been around for a while;

Chinese wholesale web sites have a veritable cornucopia of related products.

Nothing new.
I bought one of those to repair a corroded section of a flex controller
PCB about 5 years ago and it worked just fine (and still does).
Too expensive to draw complete circuits with at that price though.

Perhaps the DIY approach would be cheaper:

Though getting the chemicals would cost a lot initially.
Using the ink in an InkJet printer as in the research paper that article
is based on would be best. Still an expensive experiment though,
especially if you have to buy the printer as well.

I'm not sure it's all that reliable either so point to point soldering

try though, making your own conductive ink.
I wonder if the print heads would last beyond a single session.

Bah, bugger this new-fangled stuff.
Blank PCB + (thin!) permanent marker + HCl + H2O2 = rapid-enough
prototyping.
Worked great for me back in my student days, no reason why it wouldn't work
great now. Easy enough to tidy up blunders too - just keep some alcohol
swabs handy.
Of course, you could go the easier route of using FeCl instead of the
haphazard HCl+H2O2 mix, but back in my day (in my location), we didn't have
the luxury of FeCl.

The earliest overclocking I did would have been on 286's desoldering the
crystal, fitting a socket and then seeing how far you could push it or
on the Amiga via a clock doubler circuit to a 10Mhz 68000 (or 68010 if
you had one) with a latch to bring thew clock back to the stock 7Mhz
when the floppy drive was being accessed.
