From the free "Seek IP Smart Watch Service" website:
Want to be informed every time a particular company issues a new patent? Want to know every time other patents refer to your patents? Want complete and easy access to all of your own patents and trademarks? Seek IP gives you this kind of control, and much more.
Seek IP's Smart Vault lets you collect and store patents and trademarks, giving you access to a vast array of information regarding your own intellectual property assets, and those of your competitors. The competitive intelligence edge this gives you provides unique opportunities for you to leverage your intellectual property.
Use Seek IP's IP Watch Setup screens to identify the information you want. Seek IP gathers the patents and trademarks that meet your criteria, and, at your request, stores them for you in your own personalized Smart Vault.
