Extensions

To provide a comprehensive analysis of US patent 10057322, I will use the information available from the patent document itself and the provided search results.

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) extends the term of a U.S. patent to compensate for delays caused by the United States Patent and Trademark Office (USPTO) during the prosecution of a utility or plant patent application. These delays can include failure to issue a first office action within 14 months of filing, failure to respond to an applicant's reply within four months, or failure to issue the patent within four months of paying the issue fee. Applicant delays can reduce any accrued PTA.

To determine the specific PTA for US patent 10057322, one would typically look at the front page of the issued patent or access the Patent Term Adjustment data through USPTO's Patent Center or Open Data Portal, using the application number US14/985,968. Without direct access to the full official patent document or the USPTO's Patent Center for this specific patent's PTA details, the exact number of days of PTA cannot be stated at this time.

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is available for patents claiming products that require regulatory approval, such as certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products. PTE aims to restore a portion of the patent term lost during the premarket government approval process from regulatory agencies like the FDA. The patent must not have expired, its term must not have been previously extended, and the application must be submitted within 60 days of marketing approval. PTE cannot exceed five years or extend the patent term beyond 14 years from the date of marketing approval.

Based on the title "Network address resolution" and the technical description of US patent 10057322, it does not appear to cover a product subject to regulatory review by agencies such as the FDA. Therefore, it is highly unlikely that this patent would be eligible for a Patent Term Extension (PTE).

Continuation and Divisional Applications

A U.S. utility patent's term is generally 20 years from the earliest filing date of the patent application. For continuation or divisional applications, the 20-year term is counted from the filing date of the earliest non-provisional application in the chain of parentage.

US patent 10057322 (application number US14/985,968) has several continuation applications claiming priority to it. These include:

• US16/105,877 (US10348801B2)

• US18/750,873 (US12568134B2)

The provided information does not explicitly list any divisional applications for US10057322, but the continuation applications listed are part of the same patent family, meaning they share common subject matter and priority dates.

Projected Expiration Date

A U.S. utility patent filed on or after June 8, 1995, generally expires 20 years from the earliest filing date of the patent application. US patent 10057322 claims priority to a provisional application filed on December 31, 2014, and the non-provisional application (US14/985,968) was filed on December 31, 2015. For a patent claiming priority to an earlier application, the 20-year term starts from the filing date of the earlier application. In this case, the earliest priority date is December 31, 2014.

Therefore, the nominal expiration date for US patent 10057322 is December 31, 2034.

However, the Google Patents entry states that the "Adjusted expiration" date for US10057322B2 is October 16, 2036. This adjusted expiration date already accounts for any Patent Term Adjustment (PTA) awarded due to USPTO delays during prosecution. This means that the patent received approximately 1 year, 9 months, and 16 days of PTA (from December 31, 2034, to October 16, 2036).

Therefore, the projected expiration date for US patent 10057322 is October 16, 2036.
