Upon his death, his professional colleague the Hungarian-born Ferdinand Piatnik (1819–1885) took over in 1843, marrying Moser's widow a few years later.
Piatnik continued to expand and in 1899 bought the playing card manufacturer, Ritter & Cie in Prague.
As early as 1923 Piatnik received an 'irrevocable' national award and thus the right to use the Austrian coat of arms in its business in perpetuity.
In 1939, the Viennese parent company was incorporated into the family limited partnership Wiener Spielkartenfabrik Ferd.
In 1956, the playing card factory expanded its range to include board games, and puzzles have also been produced since 1966.
According to the company, around 10,000 board games, 100,000 playing card packs and 4,000 puzzles are sold in over 60 countries around the world every day.
