Intellectual property rights (IPR) are a perennial headache for foreign companies operating in China and critics argue that poor enforcement scares off firms from transferring technology or applying for patents.
The United States has lamented that lax controls have made possible the systematic stealing of American innovations.
Ambassador Gary Locke said a long road lay ahead before rights holders in China could feel confident that their IPR would be protected under the law. Rights holders, including many Chinese, have told us ... that courts lack consistency in the application of procedural remedies and that damages awarded do not fully compensate for losses or fail to deter future infringers, he told a forum. So long as such entrepreneurs efforts go unrewarded, Chinas efforts to develop an innovative, 21st Century economy will remain stunted.
China, he said, was clearly moving in the right direction, but the most pressing issue was reform of trade secrets law.
The United States has called Chinas theft of trade secrets a grave problem as a target company can see market position and competitive advantages from research investment evaporate as a result of corporate espionage.
Foreign ministry spokesman Qin Gang disputed the comments, saying China had made obvious achievements on IPR enforcement. On the issue of protecting IPR, we hope that the country in question can increase dialogue and cooperation and mutual understanding and not blindly exert pressure and criticise, Qin told a news briefing.
