Extensions

To provide a comprehensive answer, I need to access the official USPTO Patent Center or Public Search tools, which I cannot directly do as an AI. However, I can explain how to find this information using the provided patent text and general knowledge of USPTO procedures.

Based on the information you have provided from Google Patents and general patent law, here's how to address each point:

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) is granted to compensate for delays caused by the USPTO during the prosecution of a patent application. The total PTA is added to the 20-year lifespan of the issued U.S. patent. The USPTO calculates PTA at the time of patent issuance, and the details are typically included in the Issue Notification Letter.

To determine the specific PTA for US9651533, one would need to look up the patent's file history in the USPTO's Patent Center. The patent was filed on October 6, 2015, and issued on May 16, 2017. The USPTO's Patent Center will display any calculated adjustment to the term of the patent.

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is available under the Hatch-Waxman Act for patents claiming products (such as human and veterinary pharmaceuticals, food additives, color additives, and medical devices) that require regulatory approval prior to commercial sale. PTE aims to restore a portion of the patent term lost during the regulatory review period. An application for PTE must be submitted within 60 days of the marketing approval of the product.

Given that US9651533 relates to "Short-wave infrared super-continuum lasers for detecting counterfeit or illicit drugs and pharmaceutical process control," and the description includes applications for "non-invasive glucose monitoring," and "measuring the properties of meats" which might involve food safety or medical devices, it is conceivable that a PTE could have been sought if a product covered by the patent received regulatory approval. However, the provided patent information does not explicitly state whether a PTE was applied for or granted. This information would also be found in the patent's file history on the USPTO Patent Center.

Continuation and Divisional Applications

The provided Google Patents information lists several priority applications, which can indicate continuation, divisional, or continuation-in-part applications. A divisional application is filed when an examiner determines that an initial patent application contains more than one invention. Continuation applications are other versions of the invention and are also called children applications.

The "Priority to" dates listed in the Google Patents information are crucial for identifying related applications. For US9651533 (application number US14/875,709), the following priority applications are listed:

• US14/875,709 (filed 2015-10-06) - This is the application number for US9651533 itself.

These numerous "Priority to" entries indicate a robust patent family with many continuation and/or divisional applications filed after the original filing date of US14/875,709, which matured into US9651533. This strategy is commonly used to broaden patent protection or to pursue claims that were not allowed in earlier applications.

Related Family Members

The related family members are explicitly listed under the "Other versions" and "Priority to" sections of the Google Patents page. "Other versions" shows US20160047787A1, which is the patent application publication for US9651533. The "Priority to" list above details a large number of subsequent applications that claim priority from US14/875,709 or earlier applications in the chain. These subsequent applications are thus direct family members.

Projected Expiration Date

For utility patents filed on or after June 8, 1995, the patent term generally expires 20 years from the earliest filing date of the application, or of an earlier-filed application to which priority is claimed, subject to any patent term adjustments or extensions.

The filing date of US9651533 is October 6, 2015. The earliest priority date listed in the Google Patents summary (under "Priority date") is December 31, 2012. Therefore, the base expiration date would be 20 years from December 31, 2012, which is December 31, 2032.

However, the Google Patents information itself provides an "Anticipated expiration" date of 2033-12-17. This discrepancy suggests that Patent Term Adjustment (PTA) has been applied, adding approximately one year and 17 days to the base patent term. Without access to the official USPTO file wrapper for US9651533, the exact PTA calculation (A, B, or C delays and any applicant delays) cannot be detailed. Therefore, the projected expiration date is December 17, 2033.
