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.
