Intellectual property rights (IPRs) have been acknowledged and protected in China since the 1980s. China has acceded to the major international conventions on protection of rights to intellectual property. Domestically, protection of intellectual property law has also been established by government legislation, administrative regulations, and decrees in the areas of trademark, copyright, and patent. This has led to the creation of a comprehensive legal framework to protect both local and foreign intellectual property. Despite this, copyright violations are extremely common in the PRC. The American Chamber of Commerce in China surveyed over 500 of its members doing business in China regarding IPR for its 2016 China Business Climate Survey Report, and found that IPR enforcement is improving, but significant challenges still remain. The results show that the laws in place exceed their actual enforcement, with patent protection receiving the highest approval rate, while protection of trade secrets lags far behind. Many US companies have claimed that the Chinese government has stolen their intellectual property sometime in 2009–2019.
