Hello, all! As some of you may have noticed, our patent search feature has been down for the last few days. We encountered a glitch while moving some of the data from one server to another and, rather than having incomplete data on the site, have decided to disable the feature for the time being. Our crack tech team is working on the problem and it should be back up shortly. When it is, you’ll be able to once again enjoy access to our database of over 4 million US patents (from 1976 to present) and more than 3 million US patent publications (from 2001 to present), as well as our great visualization tools.

Thanks for your patience while we fix the error and I’ll do another post when the full database is back up.
