Extensions

To gather the requested information about US patent 9734825, I will use the USPTO's Patent Public Search tool.

Patent Term Adjustment (PTA)

Patent Term Adjustment (PTA) is granted to compensate patent applicants for certain delays incurred by the USPTO during the prosecution of a utility or plant patent application. The PTA is an addition to the standard 20-year lifespan of a US patent. The USPTO calculates the PTA at the time of patent issuance, and this calculation is typically included in the Issue Notification Letter.

To determine the exact PTA for US9734825, the official patent document or the Patent Center details would need to be consulted directly on the USPTO website. Without direct access to the official Issue Notification or Patent Center data for US9734825, I cannot provide the specific number of PTA days.

Patent Term Extension (PTE)

Patent Term Extension (PTE) is available under the Hatch-Waxman Act (35 U.S.C. § 156) for patents covering products that require regulatory approval (such as human and veterinary pharmaceuticals, food/color additives, and medical devices) before commercial marketing. This aims to restore patent term lost during the regulatory review period. PTE cannot exceed five years and cannot extend the patent term over 14 years from the date of marketing approval.

Given that US9734825 relates to "Methods and apparatus for determining a domain based on the content and context of a natural language utterance," it is highly unlikely to be eligible for Patent Term Extension under 35 U.S.C. § 156, as its subject matter does not fall within the categories of products requiring premarket regulatory approval by agencies like the FDA. No information in the provided patent text or search results indicates that US9734825 has been granted a PTE.
