Lucent Technologies Inc. v. Gateway Inc. 470 F.Supp.2d 1180 (S.D.Cal.,2007) is a patent case between Alcatel-Lucent and Microsoft litigated in the United States District Court for the Southern District of California and appealed to the United States Court of Appeals for the Federal Circuit. The litigation money involved was $1.53 billion for the first patent infringement case. Its final verdict was given in August 2007 at the Federal District Court of the United States in San Diego. The damage award finding was reversed on appeal in September, 2009 and returned for a separate trial on the amount of damages.[1]


The dispute between Microsoft and Lucent (and later Alcatel-Lucent) began in 2003 when Lucent Technologies (acquired by Alcatel in 2006) filed suit against Gateway and Dell in U.S. District Court, San Diego, California. Lucent claimed in this first San Diego case that Dell and Gateway had violated patents on MP3-related technologies developed by Bell Labs, a division of predecessor company American Telephone & Telegraph. Other patents said to be infringed relate to MPEG video technology, speech technology, internet technology, and other technologies. Microsoft voluntarily joined the lawsuit in April 2003 and Alcatel was added after it acquired Lucent.[2]

After the first San Diego lawsuit was filed, Microsoft and Lucent have filed additional patent lawsuits against each other.

In February 2007, Microsoft filed a lawsuit at the International Trade Commission claiming that Alcatel-Lucent infringed its patents.[3]

There is a second case in San Diego where Microsoft is asserting that Alcatel-Lucent infringes 10 of its patents, and yet another case in Texas where each alleges that the other is infringing its patents.[4]


In the first San Diego case, Alcatel-Lucent claims ownership of several patents relating to MP3 and MPEG encoding and compression technologies, as well as other technologies. The patents were obtained as the result of work done at Bell Labs before the break up of American Telephone & Telegraph. Certain patents at issue are:

U.S. Patent No. 5,341,457, Perceptual Coding of Audio Signals, to Joseph L. Hall and James D. Johnston. Filed: August 20, 1993 Granted: August 23, 1994[5]

U.S. Reissue Patent No. RE39,080, Rate loop processor for perceptual encoder/decoder, to James D. Johnston. Filed: August 13, 2002. Reissue of 05627938 Filed: Sep., 1994 Granted: May., 1997[6]


The first part of the San Diego case involved the '457 and '080 audio coding patents. Alcatel-Lucent claimed that Microsoft's Windows Media Player infringed these patents by virtue of its MP3 capabilities. Testimony was given by inventors James Johnston and Joseph Hall. Coincidently, AT&T inventor James Johnston was employed by Microsoft post-AT&T breakup and during the trial.[7] Additional testimony was taken from Dr. Karlheinz Brandenburg, who worked with Johnston at Bell Labs.

On February 22, 2007, a San Diego jury found for Alcatel-Lucent and against Microsoft. Alcatel-Lucent was awarded a record-breaking $1.52 billion in damages. The damages could have been $4.5 billion but the jury was unable to decide if the infringement was "willful." Microsoft disputed the verdict, maintaining that the federal jury's decision was "unsupported by the law or facts",[8] since Microsoft had already paid $16 million to license the technology from Fraunhofer IIS which, it claims, is "the industry-recognized rightful licensor".[9]

Subsequently, on August 6, 2007 the federal judge in San Diego, U.S. District Judge Rudi Brewster, granted Microsoft's motions for Judgment and for new trial, saying that the jury's decision was not supported by the evidence. The Judge's Order [10] found that there was insufficient evidence both for Microsoft's liability and for the damages model used by Alcatel-Lucent. Alcatel-Lucent appealed the judge's decision,[11] and the Court of Appeals for the Federal Circuit heard oral arguments in July 2007. The Court of Appeals published its decision [12] on September 25, 2008, upholding the dismissal of the case by Judge Brewster on two grounds. The court held that Fraunhofer was a joint developer and thus co-owner of one patent, which made Lucent lack standing to sue. The other patent was not infringed because Lucent failed to show that the accused algorithm was ever used.

A week after the first jury verdict, on March 2, Judge Brewster ruled in the second part of the case that Microsoft had not violated Alcatel-Lucent's patents relating to speech recognition and the case was therefore dismissed before going to trial. Alcatel-Lucent stated that it intends to appeal.[13][14]

The trial in the third part of the San Diego case involved four patents. In April 2008, US jury awarded Alcatel-Lucent $367.4 million in damages after finding that Microsoft had violated two patents related to the user interface in its software.[15] One of the patents infringed by Microsoft involved technology originally developed by GO Corp. concerning fundamental technology used in Microsoft's Tablet PC products.[16] (Microsoft's acquisition of the technology is the subject of a separate antitrust lawsuit against Microsoft.[17][18]) In June 2008, the trial judge upheld the jury's verdict and increased the damage award against Microsoft to $512 million to account for interest.[19]

In the fourth San Diego case, the jury issued its verdict on June 2, 2008. This time both Microsoft and Lucent were asserting that the other side was infringing its patents. The jury found that Lucent did not infringe Microsoft's patents (and one patent was invalid) and that Microsoft's Xbox did not infringe Lucent's patent. [20]
