Patent war over navigation displays
Furuno of Japan and US has filed a complaint in the US requesting an investigation into infringements of its patents.
Last week, the US International Trade Commission (USITC) announced their decision to institute an investigation into 'Certain Navigation Products' - including GPS devices, navigation and display systems, radar systems, navigational aids, mapping systems and related software.
The investigation is based on a complaint filed in September by Furuno Electric Co Ltd of Japan and Furuno USA Inc alleging patent violation in the importation and sale in the US of the products.
The Commission has identified the following as respondents in the investigation:
- Garmin of Switzerland and USA
- Navico of Norway, UK and USA
- Raymarine of UK and USA
The asserted patents generally relate to improving navigation, radar and map displays for vehicle, marine and aviation applications, in particular:
- a display of many windows on a single screen and presenting part of an image shown on one window in another
- a display system for radar that shows current and past video images
- multiple displays for users to select one or more images from different measuring devices on each display
- a radar display that redraws a sensed image when a detection range is changed.
