I increased the size of each space but the rules are the exact same as in the original problems published by Bongard.
I'm adding a link in case people aren't familiar with this type of riddles Click me!

2$\begingroup$ Indeed. The only two patterns I see are present on both sides. Have an upvote from me :) $\endgroup$– TrojanByAccidentMar 16, 2018 at 16:28

2$\begingroup$ Well obviously, there is a shark in the bottom right corner, of the third block in the second row. The block below that has a TIE-Fighter and a bat. $\endgroup$– PL457Mar 16, 2018 at 16:54

1$\begingroup$ This summarizes me: Quickly sees the way too obvious pattern in the left 6. Turns to right 6. "Oh crap". $\endgroup$– PhylypMar 17, 2018 at 1:46

Just learned what a Bongard problem is (I think), so is it...
The circles defined by the three points in each box are totally inside the boxes (on the left), but intersect with the boxes (on the right).

$\begingroup$ Weirdly enough, I 'saw' it in seconds - took me longer to open up a drawing program to confirm it might be the answer. $\endgroup$– PenguinoMar 19, 2018 at 3:59

$\begingroup$ Well done! If you draw the circles starting on the outmost part of the "dots" it's even more obvious $\endgroup$ Mar 19, 2018 at 8:45

New to the site and I am not sure if an answer like this is welcome as it is incomplete. Maybe it will serve as a hint for someone else to produce a more complete answer. Please excuse lack of correct terminology as well; this is my first experience with Bongard problems along with my first time implementing the below:
If you treat each cell as starting conditions for Conway's game of life, then several familiar patterns form (familiar to me from the few GOL I have seen). The ones on the left all decay down to patterns that do not traverse the screen. Left to right, top to bottom, L1 and L2 decay to 2x2 squares, L3 decays to a 2x2 square and an alternating - and |, L4 decays to a group of 2x2 squares and an alternating - and |, L5 decays to two small ovals, and L6 decays to a single oval.
R1 decays to three ovals, a square, and 6 alternators. R2 decays to a group of squares, ovals, and alternators. R3 decays to a square. R4 decays to a square and 4 alternators. R5 decays to an oval and 4 alternators. R6 forms what I believe is a diagonal spaceship and decays to a square at edge of screen.
Of these, with the exception of L4, the left side decays faster to simpler patterns than most of the ones on the right. The only LR differing pattern I can see is that at least one of the remnants on the left remains over an original position, where as that does not seem to be a requirement for the right. In the end I do not think I know enough about life to identify deeper patterns. I guess my implementation could be incorrect as well. It certainly was not efficient, heh.

1$\begingroup$ Your answer is incorrect, and also pretty awesome, I might steal it for a future puzzle. If any CA pattern is present, I assure you it is absolutely random $\endgroup$ Mar 19, 2018 at 8:54

$\begingroup$ Ah shoot, yeah, problem is all of these can evolve out of random arrangements. This is what I get for zooming in to far and assuming image processing solves everything. $\endgroup$ Mar 19, 2018 at 15:12
