On January 10, IFI released its annual Top 50 Patent rankings for 2011. This report is a summary of information available through IFI’s Patent Information & Technology Report (PITR) product. PITR provides high level summaries of patent trends for the companies receiving the most US patents over the last 10 years. Over 3,500 companies are covered. You might be surprised at how deep the data in PITR goes. You can drill down to actual patent numbers by US or IPC patent class. But what if you want to drill down further than that? IFI’s KMX patent analytics solution can expose the subject matter of the patents, and allow you to apply your own classification scheme to them.
