I received a note from a patent examiner regarding my estimate that there are now around 400 pre-URAA applications still pending at the USPTO. According to the examiner, the actual number of still-pending applications is 216 (excluding applications being held under a secrecy order). All of these applications have been pending since 1995 and, upon issue, will still have 17–years of patent term remaining.
This is now a miniscule number compared with the 1.2 million applications pending at the USPTO. On the other hand, all of these applications are likely quite valuable.
