US Patent 7398209, titled "Systems and methods for responding to natural language speech utterance," has an adjusted expiration date of November 9, 2025. It is currently listed with a legal status of "Expired - Lifetime" on Google Patents.

Here's a breakdown of the requested details:

Patent Term Adjustments (PTA)

While the exact number of days of Patent Term Adjustment (PTA) for US7398209 is not explicitly stated, the Google Patents entry indicates an "Adjusted expiration" date of November 9, 2025. This adjustment suggests that PTA was applied to compensate for delays caused by the USPTO during prosecution, as patents typically have a term of 20 years from their earliest nonprovisional filing date, plus any PTA. The filing date for the application (US10/452,147) that led to US7398209 was June 3, 2003. A standard 20-year term from the filing date would result in an expiration in June 2023, so the November 2025 date indicates an adjustment.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) are typically granted for patents on certain products (e.g., pharmaceuticals, medical devices) to compensate for time lost during regulatory approval processes, such as with the FDA. There is no information in the provided patent text or Google Patents entry to indicate that US7398209, which relates to natural language speech systems, received any Patent Term Extension under 35 U.S.C. § 156. Such extensions are generally specific to patents covering products requiring pre-marketing regulatory approval.
