UK-based BTG has sued Microsoft and Apple for allegedly infringing a patent which covers web-enabled software update technologies.
BTG has filed the lawsuit with New York-based Teleshuttle and Teleshuttle Technologies, the holders of the patent which BTG said is being infringed. BTG holds the worldwide licensing rights to the patent.

The lawsuit charges Microsoft and Apple with infringement of the patent alleging that Microsoft's and Apple's operating systems, as well as Microsoft Office products, incorporate the patented technologies.
The lawsuit asks for unspecified damages for past infringing activity and an injunction against future use of the technology.
BTG said it filed the lawsuit because Microsoft and Apple were causing "delay in entering into licensing agreements with BTG on commercially reasonable terms".
In June, BTG said it was actively negotiating with a number of unnamed software suppliers about licensing programs to remedy what BTG saw as an infringement of its patents.
