minifigblue Google Patent Search has several of the LEGO Company’s U.S. patent applications available online, and they make some interesting browsing.

Among the earliest patents is Patent No. 3005282 assigned in 1961 to G.K. Christiansen for a “Toy building brick … adapted to be connected together by means of projections extending from the faces of the elements and arranged so as to engage protruding portions of an adjacent element when two such elements are assembled.” Or, as H-Bare puts it “They stick together.” (an illustration from the patent appears above)

Some of the more intriguing patents in the database are for elements that never seemed to have been used in production. The interesting piece below is described in Patent 4992069
