Prudently, Theodor Tobler and his then company, Tobler AG, applied for a patent in 1909 in Bern to cover the manufacture and shape of the bar, and Toblerone thus became the first patented milk chocolate bar. The official who gave the authorising signature was one Albert Einstein who was working in the Swiss Federal Institute of Intellectual Property in Bern at the time.

Dark Toblerone was launched in 1969 with White Toblerone following in 1973.
The product has encountered rivals during its 111 year history, including a similar Kolumbo bar in Croatia, and Swiss company Chocolate Frey's triangular Mahony bars.
