Extensions

A direct search for US patent RE47642 on the USPTO website reveals that the patent is titled "Signal processing apparatus and methods" and is assigned to Personalized Media Communications LLC. This contradicts the previous understanding that RE47642 was a John Deere "Transmission Oil Line" part number and also the earlier summary about inventors from Mosaid Technologies Inc. The information from the current search for RE47642 will supersede previous erroneous findings.

Here's the detailed information for US Patent RE47642:

US Patent RE47642: Signal processing apparatus and methods

• Assignee: Personalized Media Communications LLC
• Inventors: John Christopher Harvey, James William Cuddihy
• Filed: May 14, 2018 (for the reissued patent). The abstract also mentions an earlier filing date of June 7, 1995.
• Date of Patent: October 8, 2019

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) extends the term of a U.S. patent to compensate for certain delays caused by the USPTO during the patent prosecution process. PTA applies to utility or plant applications, but not reissue or design applications. Since RE47642 is a reissue patent, it is generally not eligible for Patent Term Adjustment.

Patent Term Extensions (PTE)

Patent Term Extension (PTE) is available for patents claiming products that require regulatory approval, such as human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products. The purpose of PTE is to restore patent term lost while awaiting premarket government approval from a regulatory agency.

Given that US Patent RE47642 is titled "Signal processing apparatus and methods" and relates to a "unified system of programming communication," it does not appear to fall within the categories of products eligible for Patent Term Extension under 35 U.S.C. § 156.

Continuation Applications

A continuation application allows an applicant to pursue new or revised claims based on the same specification and drawings as a parent application, without adding new subject matter, and retains the priority date of the parent.

The search results for RE47642 mention its filing date as May 14, 2018, and also indicate that the abstract describes a "unified system of programming communication" with an earlier filing date of June 7, 1995. This suggests that RE47642 is a reissue of an earlier patent, which itself might have been part of a family of applications. The presence of a reissue patent indicates a history of prosecution and potentially related continuing applications (e.g., continuations or divisionals) from the original patent that was reissued. However, without direct access to the patent's full file history or the "Related U.S. Application Data" section typically found on the patent face, specific continuation applications cannot be identified at this time.

Divisional Applications

A divisional application is filed in response to a USPTO restriction requirement, claiming a distinct invention disclosed but not claimed in a parent application, and is entitled to the parent's filing date as its priority date. Similar to continuation applications, the existence of a reissue patent (RE47642) suggests that there might have been previous applications, including potential divisional applications, that stemmed from the original application. However, specific divisional applications cannot be identified without the patent's full file wrapper.

Related Family Members

The search results indicate that RE47642 is associated with John Christopher Harvey and James William Cuddihy as inventors, and Personalized Media Communications LLC as the assignee. The same inventors and assignee are also associated with other patents such as US Patent 10616638 and 10523350, both titled "Signal processing apparatus and methods," and RE48633, titled "Reprogramming of a programmable device of a specific version." These patents, sharing common inventors and assignee and related subject matter (signal processing and programming communication), are highly likely to be family members of RE47642. A full patent family search would typically involve examining the "Related U.S. Application Data" section of RE47642 (if available) and cross-referencing priority claims.

Projected Expiration Date

The term of a U.S. utility patent (filed on or after June 8, 1995) generally expires 20 years from the earliest filing date of the patent or its earliest priority application, with any Patent Term Adjustments added. Since RE47642 is a reissue patent, its term is tied to the original patent's term.

The search result shows that US Patent RE47642 was filed on May 14, 2018, but the abstract also refers to an earlier filing date of June 7, 1995. For a patent filed after June 8, 1995, the term is 20 years from the earliest filing date. Therefore, the patent term for RE47642 would generally be calculated from the June 7, 1995 filing date.

Calculating 20 years from June 7, 1995:
June 7, 1995 + 20 years = June 7, 2015.

However, RE47642 is a reissue patent issued on October 8, 2019, from an application filed on May 14, 2018. Reissue patents do not extend the term beyond that of the original patent. Therefore, the projected expiration date for US Patent RE47642 would be June 7, 2015.

It is important to note that this calculation does not include any potential Patent Term Adjustments (PTA) or Patent Term Extensions (PTE). As established earlier, PTA is generally not available for reissue patents, and PTE is unlikely for this type of invention. Also, maintenance fees must be paid to keep a patent in force. If maintenance fees were not paid, the patent could expire earlier.
