Microsoft isn't yet finished fighting what it considers the good fight and has filed a second appeal in its patent case against i4i. According to Microsoft, the original judgment could set a dangerous precedent for future patent cases, TGDaily reports.
The dispute stems from August of last year, in which Microsoft was found guilty of violating an XML patent held by Toronto-based i4i. Microsoft was then banned from selling or importing into the U.S. any Word products capable of opening .xml, .docx, or .docm files containing custom XML. Microsoft would appeal, but lost its case in December.
In this second appeal, Microsoft contends that "the December 22 decision creates [significant conflicts] with established precedents governing trial procedure and the determination of damages, and we are concerned that the decision weakens judges' authority to apply appropriate safeguards in future patent trials."
i4i wasn't caught off guard by the latest appeal, saying "this next step of seeking a rehearing was anticipated."
