[LUNI] Sudoko publisher follows open source model to develop games

Quote from the article below:

"Sudoku’s popularity in the United States caught Mr. Kaji by such
surprise that he did not try to get the trademark there until it was too
late. As a result, Nikoli receives no royalties from sudoku-related
sales overseas by other publishers. 

In hindsight, though, he now thinks that oversight was a brilliant
mistake. The fact that no one controlled sudoku’s intellectual property
rights let the game’s popularity grow unfettered, Mr. Kaji says. Nikoli
does not plan to trademark other new games, either, in hopes this will
also help them take off.
