New Patent Suit Threatens Bluetooth Standard
Aditi.Tuteja writes "A U.S. research institute has sued Nokia, Samsung Electronics and Matsushita-owned Panasonic for violating a patent on Bluetooth technology, potentially putting the free wireless standard at risk. The Washington Research Foundation, which markets technology from the University of Washington, is seeking damages from the three mobile-phone makers for using a radio frequency receiver technology without paying royalties. From the article: 'According to the lawsuit, Bluetooth-based computers, cell phones and headsets made by the companies have violated four patents for research done in the mid-1990s by Edwin Suominen when he was a student at the University of Washington. All four patents are now licensed by the Washington Research Foundation. The foundation's lead counsel on the case, Steven Lisa, said the court filing followed two years of informal attempts to resolve the issue with the major players in the industry.'"
I was under the impression that Bluetooth was an open standard, and it looks like the suits involve specific chipsets used by the companies in question, not the standard as a whole.
If you google him, you will find that Edwin Suominen is a patent agent who studied RF at university and assigned some patents there. Despite his name (Suominen), he doesn't seem to have any Finnish connection (Suomi, is the Finnish name for themselves). I had wondered at first whether he had any connection to another well known Finnish company which was heavily involved in the original research. What is unusual is that he seems to have acquired a number of patents (about 4) whilst studying as an undergraduate at University.
The thing is that the original BT work done in Finland/Sweden (mostly the latter) was done some time ago. It has taken a very long time to catch on in the US but started appearing in the mid nineties. Simple implementations appeared a little later and it may be interesting to look at the history of this patent against when the first single chip implmentation appeared (about 98). It could well be that some existing technology leaked.
See my journal, I write things there
