Microsoft finds itself embroiled in yet another round of the patent-infringement case leveled against it by Canadian company i4i, which submitted a responding brief on Sept. 8 rebutting Microsoft’s recent appeal.
In a statement following filing of the responding brief in the U.S. Court of Appeals for the Federal Circuit, i4i chairman Loudon Owen said his company “refutes each and every one of the same weak defenses Microsoft repackaged from the trial and raised on appeal.”
The original verdict, which ruled that Microsoft had violated an XML-related patent held by i4i, would have yanked copies of Microsoft Word, which allegedly incorporates the offending code, from store shelves by mid-October.
However, on Sept. 3, the U.S. Court of Appeals for the Federal Circuit granted Microsoft’s request to keep selling Word during the case. In addition to requiring that copies of Word be pulled from store shelves, the verdict also ordered Microsoft to pay nearly $300 million in accumulated fines.
Microsoft’s claim is that i4i failed to corroborate its creation date for the technology behind the patent. However, “Unlike in priority disputes, where requiring corroboration of an inventor’s testimony makes sense, there is no reason to require corroboration in all instances, and this court never required it,” i4i said in the Sept. 8 brief.
Damages are another issue tackled in the brief, with i4i arguing that the survey that formed the basis of its damages claims was “designed, conducted and analyzed using accepted methodology, and its admissibility was beyond legitimate question.” The damages were enhanced, i4i argued further, because of Microsoft’s “litigation misconduct.”
As the weeks have gone by, the case has attracted a good deal more attention than most patent-infringement suits submitted in East Texas, a district known for such legal actions. Small companies have a history of winning patent-infringement suits against larger companies there, although many such cases are also settled out of court.
Two major companies in Microsoft’s ecosystem, Dell and Hewlett-Packard, both signaled their intention to file friend-of-the-court briefs in the case. Both risk widespread fiscal damage were Word sales to halt, an idea expounded by Microsoft’s legal counsel in an Aug. 18 emergency motion: “Even if Microsoft ultimately succeeds on appeal, it will never be able to recoup the funds expended in redesigning and redistributing Word, the sales lost during the period when Word and Office are barred from the market, and the diminished goodwill from Microsoft’s many retail and industrial customers.”
However, i4i has previously indicated a public willingness to see the case to its courtroom conclusion: “Where we come from, if someone tries to take something that belongs to you, you stand up to them; you don’t just reach for the calculator,” Loudon Owen, chairman of i4i, said in an Aug. 17 interview with eWEEK. “We’re not in a position to guess or second-guess or speculate as to what the court is going to do.”
