I recently viewed a largely excellent online video series covering the fundamentals and history of intellectual property in the United States. Published by the Michelson Institute for Intellectual Property, the 3+ hrs of content covers patents, copyrights, trademarks, and even trade secrets. Design patents are given a relatively small section, understandably, but the history and recent context of patenting software is presented more thoroughly.
The presentation is highly visual and approachable, using dynamic animation and graphics. Aimed at novices, and more specifically, business people who don't necessarily have an IP background, it is still sufficiently broad and detailed enough to serve as refresher for those with some knowledge in the field.
Not to say there isn't room for criticism - there are a remarkable number of glaring spelling errors throughout the videos. At first I noticed one or two, but as I got later into the series they seemed more frequent, as if an editor had grown tired of making corrections. While not catastrophic, the typos leave a mark of unprofessionalism on an otherwise highly refined, and well narrated series.
In addition to the Michelson site, the videos are available through YouTube, and offered as a free course offering by Udemy.
