Telerik’s standard notice requirement is for the following language to be included in the About Box:
[Certain Portions*] Copyright © [2011 – 2015**] Telerik AD, All rights reserved.
(* you can use the term “Certain Portions” or identify the actual portions of the software that embody Telerik’s copyright(s)).
(** please refer to the copyright notice provided with each Telerik product for the applicable date range).
Hope this helps.
