The company uses Segoe in its online and printed marketing materials, including recent logos for a number of products.

[2] The Segoe name is a registered trademark of Microsoft Corporation, although the typeface was originally developed by Monotype.

The German font foundry Linotype protested, citing Segoe UI's similarity to its licensed Frutiger family of typefaces.

It was an existing Monotype design which we licensed and extensively extended and customized to meet the requirements of different processes, apps and devices.

Additionally, unlike clone typefaces, the Segoe family of fonts are not metrically compatible with Frutiger so cannot be used as replacements.

It is distinguishable from its predecessor Tahoma and the OS X user interface font Lucida Grande by its rounder letters.

A Semilight version of Segoe UI was introduced with Windows 8 in order to make a perfect lightweight down to 11 pixels.

Black and Emoji versions of Segoe UI were introduced with Windows 8.1, but only for Latin, Greek and Cyrillic scripts.

[12]I remember the team creating a special ligature in the Segoe UI font (used in Windows) to make "S" and "t" align beautifully for the word "Start".

Version 5.00 of Segoe UI contains complete Unicode 4.1 coverage for Latin, Greek, Cyrillic and Arabic (Romans only), totaling 2843 glyphs in the regular weight.

The package included TrueType and PostScript Type 1 beta versions of the Segoe branding fonts along with PowerPoint templates and marketing material.

[30] Windows Phones also include a more customized version called Segoe WP N which is designed with more clarity and narrow to enhance their take on ClearType.
