There was no break in, no hold up. No glass was smashed. But the factory on the outskirts of Shanghai was the scene of a very modern crime. Someone stole a hoard of intellectual property.

"A couple of years ago one of my IT managers copied ten thousand pages of my entire company's profile," Frank Liu told me. His company Intco has been around for 25 years.

He told me the stolen download included "our technology information, our customer list, our purchasing and supply information. Everything."

Intco is a business that makes medical devices, skirting boards and photo frames. I visited its offices at a business park in Shanghai, and a factory that sits either side of a tree-lined road south of the city.

The company recycles polystyrene waste sent to China from all over the world. Then, using heat moulding and imprinting techniques, it turns it into an array of products which end up on the floors of houses in Brazil or Russia, or hanging on walls displaying photos in the US and Britain.

"We actually have the record of how he stole it," Mr Liu told me. "He just sold it to establish another company, as his investment."

Mr Liu feels he has no recourse. He told me he went to the police but nothing happened. He said he still intends to pursue it.

His story is increasingly common here, for both local businesses and foreign firms.

Top officials from the US and China will hold their next round of trade talks this week and protecting intellectual property (IP) is a key demand for Washington. They argue American and other foreign companies in China have endured decades of theft and infringement.

Reacting to pressure

China has taken some steps to address the problem. The country only established copyright laws in the 1980s, but things have progressed relatively quickly since then.

China now has specialist IP courts, albeit - like every aspect of the judicial system - subservient to the ruling Communist Party. They are supposed to settle cases within 12 to 18 months.

Their creation was not due solely to outside pressure from foreign firms.

Chinese business figures like Mr Liu have also called for the country's legal system to better protect the innovators and entrepreneurs who have turned China into much more than the "copycat" economy it was once labelled.

Benjamin Qiu, an IP lawyer with US law firm Loeb & Loeb, told me that the Chinese are now just as litigious as foreign firms.

Foreign firms are just as likely to win a case - a good case, Mr Qiu added - as domestic plaintiffs. In the past few years Lego and New Balance have both won high-profile cases against copycat manufacturers.

There is no doubt that the trade war with the US has sped up the pace of reform in China.

President Xi Jinping recently led lawmakers, at their annual gathering in Beijing, in approving new rules for foreign investors.

The Foreign Investment Law states that the transfer of technology from foreign investors to any domestic partner must be voluntary. China has always defended this highly contentious practice by insisting it's part of an agreed commercial arrangement.

The new law also bars government officials from passing on details of foreign investors IP.

A new era?

Now though comes the hard part - enforcement.

Mr Qiu told me the next step is "detailed regulation coming out after this law, and we want to see actual cases in local courts and also from enforcement agencies."

If that follows, then he thinks "potentially the foreign IP owners will have more to protect [them] in China."

Both the EU and American Chambers of Commerce welcomed the new law, but both also criticised what they said was ambiguity in the legislation. The Americans also had concerns that it was rushed through without proper consultation.

Many foreign companies have been stung over the years in China. Most have found the lure of the massive market, or what was once rock bottom labour costs, irresistible.

Some though feel the risk is too high.

A fruit industry executive recently told me his firm wanted to buy new conveyor belts for their farms in China, but the European manufacturers said no. They feared their systems would be copied here, and they'd be wiped out.

Mr Liu can't do that. He is Chinese and wants to stay in China. But he has taken steps to try to prevent another IP theft.

He is chief executive of the company he founded, but this year he told me he's changing his title to include head of research and development. Because he can't trust anyone else with the firms' commercial secrets.

Protecting original ideas, techniques and information in China - "it's a human right" he told me.
