Hi,

I was sorting some old bricks and plates and was amazed to find so much Pat Pend
Parts (3P).

I've found mainly 2x4 and 2x3 bricks because they are easy to distinguish (they
don't have ribs). I've found also some 2x2 and 2x8 bricks and surprisingly
plates.

So I've searched for some information on the web about 3P....and found not that
much. I have so many questions :


USA           Pat. No. 3,005,282  3,034,254
VENEZUELA     Pat. No. 11,734
WEST GERMANY  DBP No. 1,076,007  1,120,335
Other Countries  Pat. Pend.

Hope that takes some of the mystery out of PAT PEND.

Some additional patent information - sorry it is USA-centric.

The first USA sets in 1962 did not list any patents on the boxes.  Around
1963-64 Samsonite started printing the two USA patents Gary referenced above on
many USA Samsonite boxes.  At a later date (probably 1966-67) Samsonite started
listing six additional patents on boxes for a total of eight.  For many of the
early sets the box can be dated this way.

The following USA patent information was found in earlier lugnet posts and I've
added a little detail.

Here are some of the earlier patents (first 8 are the ones printed on boxes):

The files can be saved to your computer and/or printed.

Have fun,

(...) PAT PEND was found on Lego bricks and parts from 1958 until the mid-to-late 1960's. 1958 was the year that TLG introduced the "binding brick" with tubes underneath. There were other patents issued for such things as sloped bricks and Lego (...) (20 years ago, 16-Mar-05, to lugnet.parts)
