| Base term, 20 years from filing | Clock starts May 21, 2004, when the earliest non-provisional application in its chain was filed (this one was filed Jan 31, 2007) | May 21, 2024 | High confidence |
| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +55 days, USPTO patent term adjustment record | Jul 15, 2024 | 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 RE43,503 and US RE46,221 issued Jul 10, 2012, and this patent's term continues in it (35 U.S.C. 251, 252) | surrendered Jul 10, 2012 | High confidence |
