Extensions

To get the most accurate and up-to-date information regarding US Patent 7,702,742 directly from the USPTO, one would typically use the Patent Center or Patent Public Search tools available on the USPTO website. The USPTO does not calculate expiration dates for patents, but provides a downloadable calculator and guides on how to obtain the necessary information to estimate the expiration date.

Based on the provided patent text and general patent law:

• Patent Term Adjustments (PTA): Patent Term Adjustment (PTA) can extend the term of a U.S. patent to compensate for delays by the USPTO during the prosecution of a utility or plant patent application. This applies to applications filed on or after May 29, 2000. Delays can include failure to issue a first office action within 14 months, respond to an applicant's reply within four months, or issue the patent within three years of the actual filing date. The specific amount of PTA for US7702742 would be detailed in the Issue Notification Letter that was mailed approximately three weeks prior to the patent's issuance. This information is not explicitly provided in the patent document itself but would be part of its official prosecution history accessible via USPTO search tools.
• Patent Term Extensions (PTE): Patent Term Extensions (PTE) are available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products to restore time lost during pre-market government regulatory review. Since US Patent 7,702,742 describes a mechanism for memory transactions across a lossy network, it is highly unlikely to be eligible for PTE, as it does not fall into these categories.
• Continuation Applications: A continuation application allows an applicant to pursue additional claims based on the same specification and drawings as a previously filed "parent" application, while retaining the earlier priority date. It is essentially a new application with new claims but the same underlying invention as the parent.
• Divisional Applications: A divisional application is a specific type of continuing application that results when the USPTO determines that a parent application contains more than one invention and issues a restriction requirement. The applicant then files a divisional application to pursue claims directed to the invention(s) not elected in the parent application, also retaining the priority date of the original application.
• Related Family Members: The patent states that it claims the benefit of U.S. Provisional Application Ser. No. 60/645,000, filed on January 18, 2005. This provisional application is a family member. The patent also lists US20090319634A1 as another version and US12/762,407 as a priority to it [cite: The provided patent text]. Patent families link patent iterations back to a priority date and can include international filings. To fully detail all related family members, a comprehensive search using USPTO or international patent search tools would be required.
• Projected Expiration Date: The patent is currently active and has a stated expiration date of October 1, 2028 [cite: The provided patent text]. For utility patents filed on or after June 8, 1995, the term generally expires 20 years from the earliest filing date of the application, subject to any PTA or terminal disclaimers. The filing date for US7702742 is January 17, 2006, and it claims priority to a provisional application filed on January 18, 2005. The expiration date of October 1, 2028, indicates that there has been an adjustment to the standard 20-year term from the earliest priority date (January 18, 2005), which would normally lead to an expiration date around January 18, 2025. This adjustment is likely due to Patent Term Adjustment (PTA) as a result of USPTO delays in prosecution. However, without access to the official USPTO patent prosecution history for US7702742, the exact PTA calculation cannot be determined here.
