Ericsson has countered claims that it has dropped three lawsuits against rival Qualcomm, suggesting it had merely "streamlined the number and scope of patents that will be tried".
The Swedish giant is alleging that Qualcomm is using its intellectual property in its technology for IS-95, the US wireless telecomms standard. It has been in dispute with Ericsson since 1995 (see Newswire 21 October).
On Tuesday, Qualcomm issued a statement claiming Ericsson had dropped three lawsuits but the Swedish company said this was part of the process of exchanging its current patents for reissued, amended and strengthened ones.
Ericsson has also claimed further ownership of technology required by Qualcomm to do business in the US. It suggests the US Patent and Trademark Office has validated 36 new and amended claims in one of Ericsson's key patents.
