Microsoft looses Patent Fight to Toronto-based Firm

 

According to Bloomberg Business Week, Microsoft Corp. has lost a challenge to a patent which led the software giant to make changes to its popular Word program. Microsoft had requested a review of Toronto‘s i4i patent by the U.S. Patent and Trademark Office. 

“Even though Microsoft attacked i4i’s patent claims with its full arsenal, the Patent Office agreed with i4i and confirmed the validity” of the patent.

The Toronto firm’s invention relates to customizing extensible markup language, otherwise known as XML. It is a format encoding data to exchange information among programs.

It appears that Microsoft will be considering appealing this decision to the Supreme Court, according to a Microsoft spokeman in Redmond, WA.  The disputed feature of the XML encoding is one used bymany large companies to add special data to Word files. 

“We are disappointed, but there still remain important matters of patent law at stake, and we are considering our options to get them addressed, including a petition to the Supreme Court” 

Last year, Microsoft lost a lowe court trial over the patent. The court issued an injunction to Microsoft to alter its Word program or cease sales. A U.S. appeals court upheld both the verdict and the injunction. 

Here are the case names: 

  • Appeals Court Decision: i4i LP v. Microsoft Corp., 2009-1504, U.S. Court of Appeals for the Federal Circuit (Washington).
  • Lower Court Decision: i4i LP v. Microsoft Corp., 07-cv-113, U.S. District Court, Eastern District of Texas (Tyler).
