Software Patent Infringement

A patent is one form of legal protection for a software invention. The patented software could be, for example, a whole computer program, a user interface, a library or other component, or an algorithm.

Patent infringement occurs when another company or person copies the invention--without the permission of the patent holder--in a country where the patent is in force. Permission to use the patented software is normally granted in the form of a license.  In the United States, infringement may include the use, sale, or even import of an unlicensed product.  

In the event of patent infringement litigation, both plaintiffs and defendants require expert witnesses.  A software expert witness helps a lawyer by reviewing source code and related documents to provide expert reports and testimony.  In the process, a software expert provides the legal team a deeper understanding of how the infraction is committed and how to properly present this to the court in simple and easy to understand terms.
