Subject: [CHMINF-L] US Pre-Grant Applications have Significant Impact on Citations Associated with Granted Equivalents – Issues with Counting Citations Part 2

Hello Everyone,

Here is a follow-up on the post from last week where I take a closer look at how prevalent the issue of patent equivalents and forward citations in the United States really is. The impact is a major one and looks to be extremely significant.

In a study of nearly 52,000 US patent documents (both granted and pre-grant applications) it was found that over 75% of the documents had forward citations associated with them. It was also discovered that even granted patent documents which didn't have any forward citations associated with them still had forward citations associated with the corresponding pre-grant application in 60% of the cases studied. This examination demonstrate a compelling need to reconcile pre-grant applications with their corresponding granted patents in the United States when looking at citations associated with the application number.
