Checking out US Patent Search System ArchPatent (Pro)

[tweetmeme source=”Intellogist” only_single=false]

ArchPatent is a US patent search system that features a post-search filtering (“drill down”) interface and has several additional features requiring a user registration. Several aspects of ArchPatent can be unlocked simply by registering for a free account, but further added-value tools can be unlocked by signing up for a paid “ArchPatent Pro” account.

Today we’ll check out some of the features unlocked by signing up for ArchPatent Pro, so read on for more information!

According to the ArchPatent website, the following features unlock by purchasing a Pro account (or signing up for a free trial):

  • Patent reassignment information integrated into search results
  • Weekly patent reassignment database updates
  • Ad-free searching
  • ArchMonitor, a customizable alert service that delivers event updates to your workspace or email

Patent reassignment data is taken from the USPTO reassignment feed and incorporated into the search results data within ArchPatent Pro. In the below screenshot, I took a search for “medical clamp,” sorted by assignee, chose “Baxter Incorporated,” narrowed the search results to only that subset, and examined the Reassignment statistics.

The reassignee data filter is shown to the left of the query results list.

From this list we can see that we may want to do further research on Fenwal, which turns out to be a former subdivision of Baxter.

For more information on searching for assignment (and reassignment) data, see our Intellogist Best Practices article on Assignment Searching. Several other patent search systems have reassignment data, including subscription search systems such as PatBase, Thomson Innovation, and CobaltIP to name only a few. US patent assignment information can be researched directly at the USPTO Patent Assignment Query.

Creating an alert is another feature available for Pro users. Alerts can be created with the click of a button from any previously executed search string, and serve to deliver notice of new records as they appear in the the weekly update to the US grants and applications database.

Alerts can be created from saved searches or directly from the search history interface.

Considering that there are many options available for free users (the aforementioned handy filtering as well as PDF downloads), and the Pro options are available for trial, you may be interested in heading to check out ArchPatent. For more information, I recommend you check out their fairly new (but helpful!) blog.
