Having already lost a patent ruling relating to the use of custom XML in Microsoft Word Microsoft has petitioned the U.S. Supreme Court to overturn a $290 million payment demand in a long running fight with Canadian Company i4i Inc.
Late last year a US federal jury ordered Microsoft to pay $290 million to the Canadian software firm who had originally sued Microsoft in 2007 for infringing upon one of its patents related to the manipulation of documents, landing the world’s largest software maker in trouble for its Word 2003 and Word 2007 products.
At the time Microsoft claimed that that patent was invalid.
Kevin Kutz, Microsoft director of public affairs, said in a statement, “Our petition to the Supreme Court focuses on proper standards of proof to determine the validity of a patent, which is a crucial issue for the proper functioning of the patent system. The Federal Circuit Court of Appeals’ ruling in our case departs not only from Supreme Court precedent, but from the rulings of all the other appellate courts, and we are asking the Supreme Court to resolve this conflict.”
Tech Flash said It’s tempting to call the timing ironic, coming on the same day that a company controlled by Microsoft co-founder Paul Allen filed a high-profile patent infringement lawsuit against Google, Facebook, Apple, eBay and several other tech companies and retailers. The situation underscores how prevalent patent litigation has become in the tech industry.
In a news release, i4i Chairman Loudon Owen said the petition was expected. “We continue to be confident that i4i will prevail,” he said.
