Mexico extradited drug kingpins Osiel Cardenas and Hector "El Guero" Palma and thirteen other major traffickers to the United States Friday as part of an effort by new Mexican president Felipe Calderon to follow through on a promise made by former President Vincente Fox to make increased extraditions to the US. Since taking office, Calderon has mobilized elite police and military forces against the rival Sinaloa and Gulf Cartels. Although the widely popular initiative is showing initial success, experts warn that Calderon must address the political and judicial corruption that allows cartels to run rampant in Mexico.

Kingpins are often able to continue running their organizations from within corrupt Mexican prisons, making the extradition of leaders a key tool for scaling back cartel activity. In November 2005, the Supreme Court of Mexico ruled that prisoners serving life sentences can be extradited abroad, overturning a 2001 decision that prevented such prisoners from answering to charges in the US insofar as punishment there might be cruel and unusual and not directed at rehabilitation of the prisoner. A 1978 treaty between the US and Mexico still prevents the extradition of prisoners who face the death penalty.

Vioxx manufacturer Merck Pharmaceuticals, which withdrew the drug from the market in 2004 after research showed it doubled the risk of heart attacks and strokes, claimed that the men's heart problems were caused by pre-existing coronary heart disease, and not the drug. After the mistrial was declared, Merck announced that the plaintiffs did not prove their cases, and that they were ready to defend against the allegations if they were brought fourth again. As of the end of last November, Merck faced 27,200 lawsuits over Vioxx and another 265 potential state-based class-action lawsuits. A federal judge rejected national class-action lawsuits in federal court early in November.

Issue ads are those that do not purport to influence an election, but rather focus attention on an issue their sponsors find important. A provision of the McCain-Feingold law prohibits mentioning a candidate in issue ads in the 60 days before a general election and 30 days before a primary.

Its purpose was to end the common practice of circumventing limits on contributions in federal elections by airing ads that avoided expressly advocating a vote for or against someone while making clear a preference for, or more often, disapproval of one candidate.

A lawsuit in which record companies allege XM Satellite Radio Holdings Inc. is cheating them by letting consumers store songs can proceed toward trial, a judge ruled Friday after finding merit to the companies' claims.

U.S. District Judge Deborah A. Batts made the finding in a case brought by Atlantic Recording Corp., BMG Music, Capitol Records Inc. and other music distribution companies against the licensed satellite radio broadcaster.

In a lawsuit last year, the companies said XM directly infringes on their exclusive distribution rights by letting consumers record songs onto special receivers marketed as "XM + MP3" players.

XM has argued it is protected from infringement lawsuits by the Audio Home Recording Act of 1992, which permits individuals to record music off the radio for private use. The judge said she did not believe the company was protected in this instance by the act.

In a statement, XM said it remains confident that the lawsuit is without merit and it will prevail.

"At this stage of the proceeding, the court's ruling is required to be based on the false characterizations set forth in the plaintiffs' complaint. The real facts strongly support our view that the lawsuit is barred by the Audio Home Recording Act. We look forward to making our case in court," the company said.

Messages for comment left with lawyers on both sides were not immediately returned.

In refusing to toss out the lawsuit, the judge noted that the record companies consent to XM's use of their copyrighted material solely for the purposes of providing a digital satellite broadcasting service.

She said XM operates like traditional radio broadcast providers who cannot offer an interactive service, publish programming schedules prior to broadcast and play songs from an artist more often than specified within a three-hour period. But by broadcasting and storing copyrighted music for later recording by the consumer, the judge said XM is both a broadcaster and a distributor, but only paying to be a broadcaster.

"The record companies sufficiently allege that serving as a music distributor to XM + MP3 users gives XM added commercial benefit as a satellite radio broadcaster," Batts said.

Although XM argued in court papers that an XM + MP3 player is much like a traditional radio-cassette player, the judge said "it is not."

"It is manifestly apparent that the use of a radio-cassette player to record songs played over free radio does not threaten the market for copyrighted works as does the use of a recorder which stores songs from private radio broadcasts on a subscription fee basis," she said.

XM shares fell 70 cents, or 4.3 percent, to $15.75 in midday trading on the Nasdaq Stock Market.

The Mountain View, Calif., maker of controller chips for PCs and LCD monitors has filed a patent infringement lawsuit against Apple (AAPL), claiming the IT giant has been unfairly using Opti technology in its Macintosh line and its Xserve servers.

Specifically, the lawsuit claims that Apple used Opti-patented "predictive snooping" technology, which involves the transfer of data from a PCI bus controller to a PCI master bus. This piece of technology helps shorten the delay in data transfer within a microprocessor.

"The complaint alleges that Apple has infringed the patents by making, selling and offering for sale desktop and portable computers and servers incorporating Predictive Snooping," Opti said in a statement.

The lawsuit was nearly identical to one Opti filed against Advanced Micro Devices (AMD) in November. The three U.S. Patent numbers referenced in the two lawsuits were also the same: 5,710,906; 5,813,036; and 6,405,291.

All three patents refer to "Predictive Snooping of Cache Memory for Master-Initiated Accesses."

The lawsuit was filed in U.S. District Court for the Eastern District of Texas on Jan. 18. The lawsuit seeks a jury trial and unspecified damages, according to the Opti statement.

Ney's prison sentence will include two years of probation and a $6,000 fine. If he completes a prison alcohol rehabilitation program to address his recently-acknowledged alcohol abuse problem, his sentence could be reduced by up to a year. During sentencing proceedings, Ney's defense team provided evidence that he was a "functioning alcoholic" whose decision-making ability was clouded by his dependency on alcohol. US District Judge Ellen Segal Huvelle rejected the claim, asserting that it didn't fully explain his corrupt behavior or excuse violating laws he was "sworn to enforce and uphold."
