Open Invention Network Announces Purchase of Fundamental Patent Portfolio and Recognizes Fred DuFresne as a Key Distinguished Inventor

Durham, NC (June 7, 2011) - Open Invention Network (OIN), a collaborative enterprise that enables innovation in open source and an increasingly vibrant ecosystem around Linux, today recognized Fred DuFresne as a Distinguished Inventor for his invention of WebMate Foundation, a server-side scripting software that predates ASP from Microsoft, JSP from Sun/Oracle, and PHP from the open source community. OIN simultaneously announced that it has acquired the underlying intellectual property, which includes nine patents and patent applications. The Distinguished Inventor Program is focused on entrepreneurial inventors, typically unaffiliated with large corporate entities, who have authored key technology patents.

Mr. DuFresne's technology was first used in the early 1990s by incorporation of server-side scripting into the website for ABC affiliate WCVB-TV in Boston, Massachusetts. His innovation would later be released as WebMate Foundation. It received significant industry accolades at the time, including an "Editors Choice" award from Network Computing. In December 1996, Mr. DuFresne was recognized as one of the 40 most influential people on the Internet by Interactive Week for the creation of WebMate.

After the invention of server-side scripting by Mr. DuFresne, PHP was advanced by Rasmus Lerdorf, and is now supported by thousands of open source developers.  As the leading server-side language, PHP is an important part of many Linux modules and applications.  Mr. DuFresne’s patents cover PHP and other server-side scripting platforms. 

"We are delighted to have acquired this fundamental intellectual property," stated Keith Bergelt, CEO of OIN. "By making these software patents available to OIN, Mr. DuFresne has demonstrated his commitment to the fundamentals of open source software."

In commenting on the award, Mr. DuFresne said, "Open source projects are frequently a combination of innovative developments and existing infrastructure, modules, and code segments.  The OIN model provides an effective IP background for these efforts and ensures that the community will continue to operate freely."
