Extensions

Based on the provided patent text and current USPTO search capabilities, here's an analysis of US Patent 10750310:

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) can add days, months, or even years to a patent's term to compensate for certain delays caused by the USPTO during prosecution. The calculation involves considering USPTO delays (categorized as A, B, and C delays) and subtracting any applicant-caused delays or overlaps.

The Google Patents information for US10750310B2 states the patent has an "Anticipated expiration" of 2025-04-04. However, it also lists the "Legal status" as "Expired - Lifetime". This immediately suggests that the "Anticipated expiration" date listed on Google Patents may represent the original 20-year term from the earliest priority date, before any PTA or other adjustments. The patent's status as "Expired - Lifetime" appears to contradict the notion of it only recently expiring or having an anticipated future expiration.

To definitively determine any PTA, one would typically need to examine the Issue Notification Letter for the patent, which includes the PTA calculation. Without access to the official USPTO patent prosecution history (which would be available through Patent Center or Patent Public Search), it is not possible to confirm the exact PTA days awarded to US Patent 10750310.

Patent Term Extensions (PTE)

Patent Term Extensions (PTE) are available under the Hatch-Waxman Act for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products. This extension aims to restore a portion of the patent term lost due to time spent awaiting premarket government approval from regulatory agencies like the FDA. A PTE cannot exceed five years and cannot extend the patent term beyond 14 years from the date of marketing approval.

US Patent 10750310 describes a system for temporary location sharing. There is no indication within the patent text that it claims a product subject to regulatory review by agencies such as the FDA. Therefore, it is highly unlikely that US Patent 10750310 would be eligible for a Patent Term Extension under 35 U.S.C. § 156.

Continuation and Divisional Applications

• Continuation Applications: A continuation application allows an applicant to pursue new claims based on the same specification and drawings as a pending "parent" application, sharing the same priority date. It must be filed while the parent application is still pending.
• Divisional Applications: A divisional application is filed when a patent examiner determines that an original application claims more than one invention. The applicant can elect one invention to prosecute in the parent application and file divisional applications for the other, unelected inventions, using the same specification and drawings.

According to Google Patents, US Patent 10750310B2 has the application number US16/698,837 and a filing date of 2019-11-27. It also lists a "Priority date" of 2005-04-04. This significant gap between the priority date and the filing date of the application leading to US10750310B2 strongly suggests that it is a continuation or divisional application of an earlier parent application, or claims priority to a chain of earlier applications.

The patent itself lists "Prior art keywords" and references earlier patents by the same inventor, Richard D. Haney, such as US6856810B1, US20030171887A1, US7062291B2, and US6975877B2, which are related to systems for exchanging GPS position data. These are likely part of the same patent family and could be parent or grandparent applications to which US10750310 claims priority.

Specifically, the Google Patents page lists "US20200100050A1" as another version. This is likely the publication of the application that matured into US10750310B2.

Related Family Members

The "Family has litigation" section on Google Patents for US10750310B2, which links to Darts-ip and Unified Patents, indicates the existence of a patent family. A patent family is a collection of patent documents that cover the same invention and share at least one common inventor. As noted in the prior art section, several earlier patents by the same inventor, Richard D. Haney, are cited and share similar subject matter, including:

• US6856810B1
• US20030171887A1
• US6847820B1
• US7062291B2
• US20020082030A1
• US6542750B1
• US6975877B2

These documents, particularly those by Haney, are highly likely to be related family members, forming a lineage of applications that claim priority back to the earliest filing date.

Projected Expiration Date

For utility patents filed on or after June 8, 1995, the basic patent term is 20 years from the earliest filing date of the application in the patent's priority chain.

US Patent 10750310B2 has a priority date of 2005-04-04. Assuming this is the earliest non-provisional filing date from which the patent claims priority, the nominal 20-year term would typically expire on April 4, 2025.

Google Patents lists the "Anticipated expiration" as 2025-04-04. However, it also states the "Legal status" as "Expired - Lifetime". Given the current date of June 14, 2026, the nominal expiration date of April 4, 2025, has passed. This aligns with the "Expired - Lifetime" status, meaning the patent has indeed expired.

Without access to the official USPTO file wrapper or a confirmed PTA calculation, it's not possible to determine if any PTA was awarded that would have extended the patent beyond April 4, 2025. However, the "Expired - Lifetime" status suggests that any such adjustment was either not significant enough to extend it beyond the current date, or the patent has expired for other reasons (e.g., failure to pay maintenance fees). The earliest priority date of April 4, 2005, dictates a 20-year term from that date, which would lead to an expiration on April 4, 2025. Therefore, based on the information available, the patent US10750310B2 is currently expired.
