How we calculated this date
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Feb 13, 2007, when the earliest non-provisional application in its chain was filed (this one was filed Aug 12, 2008) | Feb 13, 2027 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | None on file | no change | High confidence |
| Terminal disclaimer cap | None on record | no cap applied | High confidence |
| Patent term extension | None on file | no change | High confidence |
| Fee events | No fee event states this; the fee state is read from the payments the fee record holds; the fee record shows no payment for this window, and USPTO's status still reads "Patented Case" | no change | Low confidence |
| Reissue | US RE44,604 and US RE45,452 issued Nov 19, 2013, and this patent's term continues in it (35 U.S.C. 251, 252) | surrendered Nov 19, 2013 | High confidence |
