Sony Blu-ray Under Patent Infringement Probe 160
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 [compoundsemi.com]...
I think that is how you're supposed to do things...

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"

(According to the patent it was issued in 1993, If I remember reading it right..) Since the patent protection starts (and lasts 14 years from) the day you are issued the patent.
Of course after Jun 1995, they're 20 years? If I'm readnig the USPTO stuff right.

"In 1991, I made n-type gallium nitride. The following year I succeeded making p-type using a thermal annealing technique. Now all gallium nitride researchers use my technique for p-type gallium nitride. Another big breakthrough was making the first single crystal of indium gallium nitride, which we needed for an emitting layer. Finally at the end of 1993, I succeeded in making the first commercial-based blue LEDs."

The invention this woman claims to have done was already done years previous by the true inventor of the blue LED and laser diode, Shuji Nakamura. She is a patent troll, and the fact the FTC is wasting taxpayer money with an investigation into something that could've been resolved by 5 minutes of looking at dates on Wikipedia is sad.

She is requesting blocking of imports because that's the basic remedy an intellectual property right holder gets with the International Trade Commission [usitc.gov]. 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.

I call bullshit. Patents only cover the application of an idea, not the idea itself, and in the only in the country the patent was granted for a limited period of time. In fact, there is also a research exemption which allows people to use a patented technology in research activities. For example this is why generic drug manufacturers can develop manufacturing processes for on-patent drugs and get regulatory approval for the manufacturing process so that they can begin manufacturing in quantity the day the patent on a drug expires. An offshore manufacturer can have a boatload of the drug ready to land in port the day the patent exprires.
So:
1. Absolute dominion and authority - not absolute - there are exceptions.
2. Entire human race - nope, only applicable to a given country.
3. Ever - Nope. 20 years.
4. Approbation of thought - not even close. Only some active uses.
