IMAT Patent Trends


A list of 413 IMAT awards was compiled from multiple sources: a list developed by Macros, the Cancer Research Portfolio database, the IMAT Web site, and the Division of Cancer Diagnosis Program Web site. These awards were used to identify publications using PubMed. Queries were performed for each calendar year from 1999 to 2006 using the general format of the publication year and the actual grant numbers, for example “1999[dp] AND (CA089512[gr] OR R43CA089512[gr]…).” For the identification of patent applications, the same awards were used to query the U.S. Patent and Trademark Office (USPTO) Patent Full-Text and Full-Page Image Databases. Queries were performed using the actual grant numbers, for example, “govt/CA089512 OR govt/R43CA089512 OR govt/CA89512 OR govt/R43CA089512).”

Significant Results

  1. In the first 7 months of 2008, 11 patent applications have been published by the USPTO and 3 patents have been approved.
  2. For the remainder of calendar year 2007, 9 patent applications were published by the USPTO and 4 patents were approved.
  3. The number of patents published that cite IMAT awards have been relatively consistent, as evidenced by both the number of patent applications submitted and patents awarded/approved over time.


  1. The data collection method is able to identify only those patent applications and patents in the USPTO databases that cite an IMAT grant number, which assumes that all inventors acknowledged this information and that they entered the grant number using 1 of 4 iterations in the Government Interest field.
  2. The patent application office maintains records only from March 2001 to the present; therefore, patent applications published prior to 2001 will not be included in this analysis.
  3. The 2008 data represent the published results through the first 7 months of 2008 only.
