CSR Vows to Defend Bluetooth Technology Amidst Patent Infringement Claims

Strategic Insights

— 1 min read

A Washington Research Foundation lawsuit claims that CSR's bluetooth chips have infringed US patents held by the University of Washington. The lawsuit targets top mobile phone manufacturers, including Nokia, Samsung, and Panasonic, for using CSR's technology without a licence. CSR has rejected the claims, stating that the suit is "without merit" and will "defend its products vigorously." The case has significant implications for the mobile phone industry, as it could lead to increased costs for devices that use bluetooth technology.

Key Takeaways:

  • CSR's Bluetooth technology is at the heart of the complaint, with the University of Washington claiming that CSR's chips have infringed its radio frequency receiver patents.
  • The lawsuit targets Nokia, Samsung, and Panasonic, with the Washington Research Foundation seeking a settlement it has been pursuing for three years.
  • CSR has a market share in excess of 50% in the bluetooth sector, but the company has not disclosed what proportion of its sales are derived from North America.
  • Patent disputes have become commonplace in the mobile phone sector, with Research In Motion paying $612.5m to NTP last year and Nokia still embroiled in a patent dispute with Qualcomm.
  • The case could potentially drive up the cost of devices that use bluetooth technology, as CSR's customers may need to pay royalties to the University of Washington.
  • CSR has vowed to defend its products vigorously, but the impact of the suit on the company's sales is unclear.
  • Broadcom, a competitor to CSR, is paying a licence fee to the University of Washington, showing that other companies are willing to pay to use the technology.

Statistics:

  • CSR's market share in the bluetooth sector exceeds 50%.
  • The region of North America accounts for less than 20% of the global bluetooth market.
  • The company's shares fell nearly 3% to 640p on the back of the action.
  • Research In Motion paid $612.5m (PS314m) to NTP last year as part of a patent dispute.
