Hi washout03-

"Acer palmatum seed is notorious for germinating sporadically. Germination of Japanese maple seeds (Acer palmatum) is not difficult, but it can be a bit tricky if your wife or husband doesn't let you take over part of the refrigerator!
First of all we soak the seeds in lukewarm (not hot!) water for 48 hours. This softens the seed coat a little. Next we mix the seed with a little damp (not too wet) sphagnum moss or peat and put it in a plastic zipper bag. Leave the seeds in this humid atmosphere for 4-6 weeks at room temperature.
Now comes the tough part - leave the zipper bag in the refrigerator for 60 to 90 days. This is to mimic the natural action of seeds going through a winter season. Technically it is called 'stratification'.
After the 90 days sow in trays or pots filled with a good seed compost. If you have a seed propagator use it or find a warm place to maintain a steady temperature of 65-70F (18-20C)"
I believe the ones you see germinating are last years drop. Every source I found states closely what I have quoted above, so I doubt the seeds are able to germinate in the same season they drop.
For further on why it is not likely they are this year's, see the following link...

I would be interested to see another source that has found a way around stratification.
