Thank you for this very interesting study. The recent USPTO/FDA listening session featured a number of speakers complaining about the ease with which companies allegedly obtain excessive patent protection. Many of the statistics and examples cited seemed completely at odds with my own experiences with TC 1600, so it's good to see more objective data and analysis of what is happening in the USPTO.

Useful data and analysis, many thanks for putting in the time and effort to assemble this.
