Lipperhey failed to receive a patent since the same claim for invention had also been made by other spectacle-makers[6][4] but he was handsomely rewarded by the Dutch government for copies of his design.

Lipperhey's application for a patent was mentioned at the end of a diplomatic report on an embassy to Holland from the Kingdom of Siam sent by the Siamese king Ekathotsarot: Ambassades du Roy de Siam envoyé à l'Excellence du Prince Maurice, arrivé à La Haye le 10 Septemb.

1608 (Embassy of the King of Siam sent to his Excellency Prince Maurice, arrived at The Hague on 10 September 1608).

This report was issued in October 1608 and distributed across Europe, leading to experiments by other scientists, such as the Italian Paolo Sarpi, who received the report in November, the Englishman Thomas Harriot, who was using a six-powered telescope by the summer of 1609, and Galileo Galilei, who improved the device.

[8] This "Dutch perspective glass" (the name "telescope" would not be coined until three years later by Giovanni Demisiani) had a three-times (or 3X) magnification.
