About Sergey Aleynikov
Born 1970. Sergey Aleynikov is an engineer.
Career Around 1990, Sergey Aleynikov emigrated from the Soviet Union to the United States.
He authored a telecommunications patent and contributed to a number of open-source Erlang and C++ projects. He also published several Perl modules on CPAN.
Aleynikov was employed for two years, from May 2007 to June 2009, at Goldman at an ultimate salary of $400,000. He left to join Misha Malyshev's Teza Technologies, a competing high-frequency trading firm which offered to triple his pay. According to Assistant United States Attorney Joseph Facciponti, "the bank has raised the possibility that there is a danger that somebody who knew how to use this program could use it to manipulate markets in unfair ways.". Facciponti's words in the courtroom contradicted to what David Viniar, Goldman's CFO, said a few days later on the earnings call that the sustained losses would be "very, very immaterial". Aleynikov acknowledged downloading some source code, but maintained that his intent was to collect exclusively open-source software that is not proprietary to his then-employer. The counts included theft of trade secrets (count 1), transportation of stolen goods (count 2), and illicit obtainment of data from a protected computer (count 3).
On July 16, 2010, Aleynikov moved to dismiss the indictment for failure to state an offense under any of the three statutes invoked: the Economic Espionage Act of 1996, the National Stolen Property Act, and the Computer Fraud and Abuse Act. He argued that the acts he was accused of did not constitute a crime. On September 3, 2010, the federal judge, Denise Cote, dismissed the count 3 but denied the rest of the motion.
In December 2010, Aleynikov had a jury trial in the United States District Court for the Southern District of New York. Certain trial proceedings were not public. On December 10, he was convicted of the remaining two counts, including theft of trade secrets and transportation of stolen property. Later, he was sentenced to 97 months (8 years) in prison, three years of supervised release following his prison sentence, and a $12,500 fine, despite the recommendation of the Federal Probation Service of suggesting a 24 month (2 years) sentence.
Three weeks before sentencing, Aleynikov was incarcerated on request of the government, as he was judged to be more of a after separating from his wife.
In March 2011, Aleynikov appealed the conviction, asking the Second Circuit to review the District Court's decision denying his original motion to dismiss the indictment for failure to state a claim. Aleynikov was released from custody the next morning.
On April 11, 2012, Dennis Jacobs, Chief Judge of the United States Court of Appeals, published a unanimous decision in a written opinion
By this time, Aleynikov had divorced and lost his savings. According to his lawyer, his life had been "all but ruined" as a result of his incarceration.
The government did not seek reconsideration of the Second Circuit's ruling, thus ending federal action against Aleynikov.
Later, on December 18, 2012, the Congress enhanced the 1996 Economic Espionage Act, in order to cover similar acts in future rulings, in a law referred to as the "Theft of trade secrets clarification act of 2012".
NY State prosecution Arrest, trial, and acquittal On August 9, 2012, Aleynikov was re-arrested and charged by Manhattan District Attorney Cyrus Vance, Jr., on behalf of New York State, with "unlawful use of secret scientific material" and rejected the prosecutors' plea offer of accepting a single count offense and serving no jail time. On April 5, 2013, Aleynikov lost his motion to dismiss based on double jeopardy. In rendering the decision, New York State Supreme Court Justice Ronald Zweibel stated that Aleynikov's acquittal in federal court only precluded the federal government from retrying Aleynikov. The state of New York, as a separate sovereign, could continue pursuing charges against him.
On June 20, 2014, upon reviewing the evidence, Justice Ronald Zweibel published a 71-page opinion in which the court ruled that the FBI "did not have probable cause to arrest defendant, let alone search him or his home." The arrest was "illegal", and Aleynikov's "Fourth Amendment rights were violated as a result of a mistake of law." Besides finding that he was arrested illegally without probable cause, the court excluded the majority of evidence passed by the FBI to state prosecutors, as that property was supposed to be returned to Mr. Aleynikov upon acquittal.
On May 1, 2015, following a trial before a New York state jury, he was cleared of the unlawful computer-related material duplication charge but found guilty of one count of unlawfully using secret scientific material. The jury deadlocked on the third count. On July 6, 2015, Justice Daniel P. Conviser dismissed the two remaining charges finding that, as a matter of law, Aleynikov did not violate the statute, and no rational jury could convict him of those charges. In his opinion, he wrote:
The statute criminalizing unlawful use of secret scientific material was enacted in 1967 but rarely utilized. The word "tangible" had never been defined by the New York Penal Law or in any reported court decision involving that statute. The one reported decision in which the statute did receive legal scrutiny — People v Russo (131 Misc 2d 677 [Suffolk County Ct 1986, Copertino, J.]) — was not informative with respect to the issues here.
On January 24, 2017, Aleynikov's conviction was reinstated by the First Department of the Appellate Division of the New York Supreme Court. The appellate court found the trial court's reasoning—that an electronic copy of the code was not a "tangible" reproduction—made "little sense," as a compact disc and a thumb drive are both "unquestionably tangible." The appellate court also found that the trial court erred in concluding that Aleynikov lacked "intent to appropriate," holding that the evidence "permits a rational inference that defendant intended to exercise permanent control over the use of Goldman's source code, as opposed to a short-term borrowing."
In the opinion on the 330.30 motion, the trial court's judge criticized decision of the appellate court:
On April 20, 2017 New York Court of Appeals granted Aleynikov's motion to appeal the reversal decision of the intermediate New York's appellate court. The New York Court of Appeals affirmed the decision of the Appellate Division on May 3, 2018, and he was sentenced to time served. Aleynikov's lawyer, Kevin Marino, criticized the conviction, and indicated that he will appeal the outcome:
Mr. Aleynikov was twice placed in jeopardy for the same offense. He was acquitted in federal court because the source code copy he made was not tangible and convicted in state court because it was tangible. That’s double jeopardy. And if they were going to ask for time served, why did they waste six years and millions of taxpayer dollars pursuing this case? It is an appalling abuse of power by an office becoming well-known for it. The judge dismissed the case with respect to Aleynikov's federal prosecution, finding that the agents were warranted in believing that Aleynikov had violated the National Stolen Property Act and the Economic Espionage Act. Aleynikov's malicious prosecution claims in connection with his prosecution in New York state court were stayed pending the District Attorney's appeal of the New York trial court's decision to set aside his conviction.
