In April of 2009, a federal jury in the District of Rhode Island determined that Microsoft Corp. had infringed U.S. Patent Number 5,490,216 (the ‘216 patent). Accordingly, the jury found that Microsoft owed $388 Million in damages to Uniloc USA, Inc. and Uniloc Singapore Private Limited, who held rights in the ‘216 patent.  For a general article on this case, click here.

Given that an asserted patent such as the‘216 patent can be subject to a wide variety of attacks during litigation, when such patents survive litigation and are found to be infringed, they may point to good examples of claim drafting -- especially when enormously large amounts of damages were at stake. 

The ‘216 patent is entitled “SYSTEM FOR SOFTWARE REGISTRATION” and, as the name suggests, involves a software registration system which prevents use of unauthorized copies of software.  More specifically, the system only allows the software to run if a proper licensing procedure has been followed.

In this regard, the ‘216 patent, which includes both system and method claims, may be instructive, particularly with regard to claiming computer-related types of inventions which often involve system aspects as well as the related methods for using such systems.  U.S. Patent Number 5,490,216 can be found here.
