Lego discovered that Page hadn't patented his bricks in Denmark, copied them more or less exactly (though they'd improve the design later), and the rest is history. Page killed himself in 1957, apparently without ever hearing of Lego's success. Lego bought Kiddicraft in 1981 to solidify their legal claim before suing Tyco for copying their bricks.

They say the plastic blocks WERE patented, but Lego (allegedly) didn't care or perhaps as you mentioned the patent didn't apply in Denmark according to some commenters as well.
As the article notes, Lego has been very aggressive pursuing perceived design violations.
Edit: Nevermind, just had to search Tyco Toys
That said, I have the feeling that when I was a kid there was a bigger variety of "joinable" toy systems. Lego has gotten so big that all of them vanished by now. However, that's just ust based on my gut feeling, I don't have real data for that
Our oldest got a couple of the small proper-Lego Easy-To-Build sets when she was 2 1/2. That worked out very well.
Obviously we had to play together with her the entire time, and assist with the smallest pieces, but we quickly developed our own vocabulary for orienting parts along the different axes ("rotate" is around global z-axis, while "turn" is around global x- or y-axis, etc.) I'm positive it did wonders for her spatial cognitive abilities.
Especially the digger was a big hit, we must've built and rebuilt it dozens of times. Unfortunately it's no longer for sale:

Nowadays she's does a lot of freeplay with the bunnies and Elsa and stuff, but we still regularly do the teardown and rebuild of e.g. her Arctic Helicopter set:

FWIW, most of the Lego City series has that "join all the sets together" vibe going.
Lego. They are Lego bricks not Legos.
> A subtle refinement (a “graphic tightening” in LEGO’s words) of the 1973 logo for better digital (i.e. internet) reproduction.
Digital/internet reproduction in 1973? The web wasn't invented until 1990 and didn't really catch on until around 1997. In fact computers didn't exist in the home and the computers that did exist were text based. The personal computer revolution really happened after the IBM PC was released in 1981.
> Given the 1973 logo ( http://www.logodesignlove.com/images/evolution/lego-logo-12.... ), in 1998 the image was tightened to make it easier to print digitally ( http://www.logodesignlove.com/images/evolution/lego-logo-13.... )
As far as the changes go... look at the removal of white space in the area between the 'L' and 'E' and within the 'O'. Furthermore, the middle bar of the E was made more pronounced, and the upper terminal of the 'G' was made more regular.
Anything I missed.
I can see what would reduce file size, remove some jaggies on colour boundaries of highly compressed images but it seems more likely to be effective with logoed merchandise (like dye-sub t-shirts, etc.). Is there any good analysis somewhere of what the redesign achieved digitally?
I think in the print world you can assume decent quality like 300 DPI. Whereas the new logo, with its thickening or removal of fine details, is more friendly toward low-resolution computer displays. Look at what happens when those two logos are resized to 60×60 pixels, for example.
