For Spring 2025, Professor Rosenberg recommends the following blogs:
Technology and Marketing blog (https://blog.ericgoldman.org/) - maintained by the author of the primary textbook
Patently - O (https://patentlyo.com/) - reputable patent (and overall IP) blog
The TTABlog (https://thettablog.blogspot.com/) - best trademark law blog out there
Professor Rosenberg also encourages consultation with articles and web content published by reputable law firms, but with a "trust but verify" approach (which is good advice for any resource evaluation!). Check with her about a particular firm/attorney's article.
