[22] = 12/12/2001, thus use Rule 2. Earliest related application + 20 years = 07/07/2020. Note the asterisk (*) near the grant issue date [45] and the corresponding information on the front page published below the ‘Assignee’ information (INID code 73) indicating a terminal disclaimer has been filed as well as 0 days PTA. Upon inspection of disclaimer information for this record in PAIR, it reveals the patent would not extend beyond the expiration date of <strong>US</strong>6960613 (see Appendix 2). It also confirmed in PAIR that the PTA is 0 days (see Appendix 1). The full term expiry of <strong>US</strong>6960613 is calculated below: [22] = 20/08/2003, thus use Rule 2. Earliest related application + 20 years = 07/07/2020. Thus full-term expiry is 07/07/2020 plus 0 days PTA, with expiry not exceeding 07/07/2020 = 07/07/2020.
Example 7. [22] = 10/01/2002, thus use Rule 2. Earliest related application + 20 years = 18/03/2011. Note: ‘Related U.S. Application Data’ is listed at INID code 60. Note there is no asterisk (*) near the grant issue date [45], however there is an asterisk on the front page published below the ‘Assignee’ information (INID code 73) indicating PTA of 334 days is applicable. Upon inspection of the PTA for this record in PAIR, it is confirmed that the PTA is 334 days (see Appendix 1). Thus full-term expiry is 18/03/2011 plus 334 days PTA = 15/02/2012.
