Solid Oak Software Inc. is accusing the Chinese company Jinhui Computer System Engineering Co. of stealing some if not all of the code for CyberSitter for use in the new filter. The Chinese government will begin requiring all PC manufacturers to install this filter on computers sold in China starting in July. Solid Oak received an anonymous tip that the software had been stolen and compared the code from the two programs and found many similarities. These include a list of CyberSitter serial numbers and an update to an older version of CyberSitter. The major problem they face here is that it isn't a violation of US copyright law, and they would need to fight this under Chinese law in a Chinese court. Something tells me the Chinese government wouldn't be too inclined to fight this.
