Tang and Van Slyke Inducted into National Inventors Hall of Fame for Development of OLED Display Technology

Organic light-emitting diodes (OLEDs) are semiconductor films composed of an organic compound having electroluminescent properties which utilize an electrical current to emit light. The technology has wide applications and has been incorporated into digital displays for mobile phones, automotive dashboards and television screens. OLEDs can be constructed to be thinner and lighter than liquid crystal displays (LCDs) and also provide…

CAFC invalidates Boston University patent claim for lack of enablement

“In sum, Defendants showed that epitaxially growing a monocrystalline layer directly on an amorphous layer would have required undue experimentation—indeed, that it is impossible,” the Federal Circuit found. The appellate court also found that Boston University created its own enablement problem by seeking a construction for “a non-single crystalline buffer layer” which included a purely amorphous layer. Along with reversing the district court’s denial of JMOL, the Federal Circuit dismissed-as-moot Boston University’s cross-appeal of the district court’s denial of attorney’s fees and enhanced damages.

Mark Cuban-backed LuminAID receives first U.S. patent, completes $2 million in sales through 2015

The company has been earning a bit of acclaim from media publications for its technology. Tech news outlet CNET has reported that, when deflated, 50 LuminAID solar-powered lights can ship in the same amount of space as eight flashlights. Popular Science also gave the product a glowing review as a useful accessory for campers or hikers. The product hasn’t just attracted media attention, however. It also has wooed the financial backing of Mark Cuban, one of the regular business investors featured on hit reality TV show Shark Tank. Cuban, a billionaire tech investor and owner of the NBA’s Dallas Mavericks, offered to invest in LuminAID’s business on an episode of Shark Tank airing in February 2015.

Nobel Prize Innovation: Lighting the World with Blue LEDs

With the advent of blue LED lighting, it is now possible to create white light devices by combining blue light with red and green. As the Nobel Foundation points out in their background report on the 2014 physics laureates, “Incandescent light bulbs had lit the 20th century; the 21st century will be lit by LED lamps. The fact that LEDs could supplant all incandescents and fluorescents in lighting applications alone has major implications for energy efficiency in our world. In an LED bulb, about half of the electricity charging the diode is converted into light, whereas incandescent bulbs only convert about four percent of their charge into light.
