A Review of 2015 Green Patent Suits Filed
A summary review of green patent complaints filed in 2015 reveals that LED and Smart Grid technologies were the primary areas of dispute. Complaints filed in 2015 in areas such as biofuels, hybrid vehicles, and solar reflect the growth in clean energy patents issued in these technology sectors. LED Technology – The Federal Energy Star website says that LED lighting, when designed well, is different from incandescent and compact fluorescent lighting in that LED lighting is more efficient, durable, versatile, and longer lasting. In line with the growth of LED technology, this LED technology led with the number of patent complaints filed in 2015. At the end of 2015, Bluestone Innovations LLC filed 13 complaints against not only other LED manufacturers, but also retailers asserting infringement of Bluestone’s U.S. Patent No. 6,163,557, which directs to group III-V nitride films. The accused products in Bluestone’s suits are LED lightbulbs with group III-V nitride epitaxial films.
