When it comes to fighting fakes, Alibaba’s head of internet security says cooperation beats the courtroom any day.

Ni Liang, who runs the Hangzhou, China-based company's anti-counterfeiting operations, was speaking to Reuters days after Gucci, Yves Saint Laurent and other luxury brands owned by Paris-based Kering SA sued Alibaba in New York, alleging the e-commerce giant had knowingly made it possible for counterfeiters to sell fakes.

Ni said brands had a better chance of succeeding in clamping down on the pervasive counterfeit trade if they talked to Alibaba, instead of suing it.

The company has been dogged for years by accusations that it doesn't do enough to fight intellectual property rights violations and also listed counterfeits as a risk before its record-breaking $25 billion IPO in September. “I strongly believe that spending money on lawsuits could result in a completely different outcome than cooperating with us,” Ni said in an interview.

“If a brand doesn't cooperate with us, we'll still fight fakes for them... But when we cooperate we can fight better.”

Alibaba employs some 2,000 employees to battle counterfeits. At its internet security command centre, a computer screen covering an entire wall tallies in real-time attempts by vendors to list suspected counterfeits and shows which brands they were trying to sell.

Another 5,000 “volunteers” around the country, including sellers and buyers, help identify vendors of phony goods, Ni said, adding that Alibaba spent about 100 million yuan ($16 million) last year to covertly buy products and check their authenticity. Alibaba’s two popular platforms are Taobao, on which consumers buy and sell goods to each other much like they do on the marketplace run by US-based eBay Inc, and Tmall, an online shopping mall that vendors use to sell their products, similar to Amazon.

Overall, Alibaba's platforms have seen a drop in the number of counterfeits as a percentage of goods traded, Ni said, but added the number of fake products discovered by the company rose two-thirds to 130 million last year from 80 million in the year 2012.
