The Japanese government has posted a list of "Suspended Provisions" in the TPP. As I understand it, this means the provisions will be suspended if the TPP-11 go forward with the agreement, but could be restored if the U.S. decides to join later. Some of the most important suspended provisions relate to intellectual property:
9. Patentable Subject Matter - Article 18.37.2 and 18.37.4 (Second Sentence)
10. Patent Term Adjustment for Unreasonable Granting Authority Delays - Article 18.46
11. Patent Term Adjustment for Unreasonable Curtailment – Article 18.48
12. Protection of Undisclosed Test or Other Data- Article 18.50
13. Biologics - Article 18.51
14. Term of Protection for Copyright and Related Rights - Article 18.63
15. Technological Protection Measures (TPMs) - Article 18.68
16. Rights Management Information (RMI) - Article 18.69
These are a big deal, and should make some TPP critics happy (although I'm not sure if it will make them happy enough to support the TPP).
There are also a number of investment provisions that were suspended, but as far as I could tell, none of those relate to systemic issues about ISDS/investment protection.
