Patent Term Adjustments (PTA) and Patent Term Extensions (PTE):
The Google Patents entry for US8104492B2 does not explicitly list any Patent Term Adjustments (PTA) or Patent Term Extensions (PTE) in a dedicated section. However, the legal events section mentions a "Patent reinstated due to the acceptance of a late maintenance fee" on February 24, 2020, with an effective date of March 1, 2020. This indicates the patent's term was at risk of lapsing and was subsequently reinstated. Patent Term Adjustment (PTA) is granted to compensate for administrative delays incurred during prosecution before the USPTO, while Patent Term Extension (PTE) is awarded for delays in obtaining regulatory approval. The provided data does not specify if any PTA or PTE was applied, but the reinstatement suggests that timely maintenance fees are crucial for the patent's full term.
