Personally, I am tired of trying to remember the location of subfolder or email contains a reference I want to share with a colleague or patent attorney. I have given up the old way and embrace the new and started using Connotea, a free (of course) social networking service that now manages my references, important web postings and media reports with the touch of a toolbar button.
Connotea is a online reference management service for scientists, researchers, and clinicians, created in December 2004 by the Nature Publishing Group. It is an easy to use social bookmarking tool that allows you to track any published reference to your company, product or anything else of interest to you. Although Connotea is originally aimed at scientists, it is useful for any group tracking the public disclosures such as media stories or competitor positioning. Users may bookmark any webpage they choose and assign keywords (or 'tags') to your references which can be used later to search for related publications.
Because your library is online, Connotea easily allows you to share a part or your entire library at any time. Simply provide your colleagues a link to the list of references you want your colleagues to see. This tool save time (and money?) when working with your patent attorney. You can provide your patent counsel with links to relevant publications when drafting a patent application or filing an IDS (information disclosure statement). I also use it to track competitive IP and news stories for my clients. It is great!
