Sony Blu-ray Under Patent Infringement Probe

Lucas123 writes "The US International Trade Commission said it will launch an investigation into possible patent infringements involving Sony's Blu-ray players and other technologies using laser and light-emitting diodes, such as Motorola's Razr phone and Hitachi camcorders. The investigation was prompted by a complaint filed in February by a Columbia University professor emerita who says she invented a method of using gallium nitride-based semiconductor material for producing wide band-gap semiconductors for LEDs and laser diodes in the blue/ultraviolet end of the light spectrum. Her complaint asks the ITC to block imports of LED and laser diode technology from Asia and Europe. The total market for all types of gallium nitride devices has been forecast at $7.2 billion for 2009 alone."

For everyone yelling 'patent troll,' realize that she has been trying to enforce her rights since at least 1995. She also seems perfectly willing to license the technology http://www.compoundsemi.com/documents/articles/cldoc/7121.html...

I think that is how you're supposed to do things...

"Clearly Sony developed this on their own, so you can't even say they stole it."

Really? Given that her patent claim is 12 YEARS OLD, I don't think the word "clearly" means what you think it means.

"U.S. Patent No. 4,904,618, "Process for Doping Crystals of Wide Band Gap Semiconductors," and U.S. Patent No. 5,252,499, "Wide Band-Gap Semiconductors Having Low Bipolar Resistivity and Method of Formation"

I think she'll go away once infringement has been settled. Having settled with Philips and Toyoda this doesn't look much like a troll to me.

Re:If you patent something

But perhaps there should be a time limit on how long the patent holder has to sue, after a product is openly known to use a patented technology. This does exist. It's called the doctrine of laches and estoppel. If you know someone is infringing your patent and you either refuse to sue or lead them on to believe that you won't sue, you can be barred from suing. You can rebut this though if you show that you had no money and couldn't sue or you were negotiating with them during the entire time.

Re:I'm missing something

[The Empiricist]

Why is she requesting that all imports of the tech in question be stopped? Doesn't this sort of thing usually just end with a licensing agreement? The inventor gets paid, and everybody goes on. The article doesn't mention that she is involved with any sort of competitor, so it just seems sort of malevolent for her to try and put a halt to the entire market.
I certainly hope there is a better explanation, though.

She is requesting blocking of imports because that's the basic remedy an intellectual property right holder gets with the International Trade Commission. I don't think it is even possible to get damages for infringement in the ITC (although a regular lawsuit to go after damages can still be filed). You also can't use ITC proceedings to prevent infringement within the country.

Some advantages of going to the ITC include speedy proceedings (so you're not still engaged in the suit 10 years later) and enforcement of exclusion orders by customs. Because the ability to import a set of goods is often vital, the threat of such exclusion orders can provide a powerful motivation to license if it appears likely that the plaintiff will win.

Another advantage is that the ITC is fairly specialized. It has people who really know the law and can pick up on technical nuances readily. ITC decisions may be higher-quality than the decisions that come from the district courts because either party can demand a jury in patent cases in the district courts and because district courts do not have the specialized legal knowledge and experience with technical cases.
