Extensions

To provide the most accurate details regarding patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and the projected expiration date for US patent 8803836, I need to access the official USPTO patent database directly. While Google Patents provides some of this information, for definitive legal and patent term data, the USPTO's own systems (such as Patent Center or Patent Public Search) are the authoritative sources.

However, based on the provided Google Patents data and general knowledge of patent term calculations:

Patent Term Adjustments (PTA) and Patent Term Extensions (PTE)

The Google Patents record for US8803836 states "Anticipated expiration 2029-12-30." It also shows a filing date of "2013-08-14" and a priority date of "2009-01-13."

Generally, the term of a U.S. utility patent is 20 years from its earliest effective filing date. This "earliest effective filing date" can be influenced by priority claims to earlier-filed applications. Patent Term Adjustment (PTA) compensates for certain delays incurred by the USPTO during prosecution, extending the patent's term beyond the 20-year mark. Patent Term Extension (PTE) is separate and is typically granted for delays in regulatory review for certain products (e.g., pharmaceuticals).

The Google Patents page for US8803836 does not explicitly detail the PTA applied, but the projected expiration date of "2029-12-30" suggests that some PTA has likely been granted, as 20 years from the filing date of August 14, 2013, would be August 14, 2033, while 20 years from the priority date of January 13, 2009, would be January 13, 2029. The listed expiration date falls after the 20-year term from the priority date, indicating a potential adjustment. For an exact PTA calculation, accessing the Patent Center or Public PAIR system would be necessary. The Google Patents platform itself notes that its "Legal status (The legal status is an assumption and is not a legal conclusion. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.)".

There is no indication of Patent Term Extension (PTE) for US8803836, which is usually applicable to drug, biologic, animal drug, and medical device patents.

Projected Expiration Date

The Google Patents record explicitly states the "Anticipated expiration" date as 2029-12-30.

This date is calculated based on the earliest effective filing date (which, for a continuation, divisional, or continuation-in-part application, is generally 20 years from the filing date of the earliest application to which a benefit is claimed under 35 U.S.C. 120, 121, or 365(c)) plus any applicable Patent Term Adjustment (PTA). In this case, the earliest priority date is January 13, 2009, from the Japanese application. Twenty years from this date would be January 13, 2029. The projected expiration date of December 30, 2029, implies a PTA of approximately 11 months and 17 days.
