How we calculated this date
One row per rule, each showing its own input and what it did to the date. A step we could not verify says so instead of resolving itself.
| Step | Input | Date after this step | Confidence |
|---|---|---|---|
| Base term, 20 years from filing | Clock starts Dec 24, 2007, when application PCT/IB2007/004090, the earliest non-provisional in its chain, was filed (this one was filed Mar 6, 2009) | Dec 24, 2027 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +102 days, USPTO patent term adjustment record | Apr 4, 2028 | 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 RE45,029 issued Jul 22, 2014, and this patent's term continues in it (35 U.S.C. 251, 252) | surrendered Jul 22, 2014 | High confidence |
