Frequent readers of IPWatchdog know that we look for any excuse to talk about patents and holidays provide an opportunity to discus thematically relevant patents for interesting innovations. This year we are focusing on Christmas lights. Some of these patents are for Christmas tree lighting, some are for outdoor decorative lighting and we have one from the era that just caught our eye as we were researching. So sit back and enjoy the wonderful world of patents, Christmas style. And be sure and check out our other Christmas patent articles.
