All about this site and our patent search engine

PatentsOnline provides free access to all US patents, patent applications, and partial European data, free PDF downloading, and more. A patent search engine on the web, and an ever-expanding data collection, we are rapidly becoming the premiere way to search patents -- free!

Our free accounts allow you to save searches, create portfolios of documents, get notified when new patents of interest are published, and more?

Other Services: We can provide patent analytics, patent portfolio analysis and valuation, and advanced search abilities based on Latent Semantic Indexing (LSI). Let us know how we can help.


What data does this site have? We have hundreds of gigabytes of data which includes the full text of US patents. As more patents are published, we add them.
