Extensions

To determine the full legal life and related applications for US Patent 7812505, we need to consult official USPTO records.

A patent's term is generally 20 years from its earliest effective filing date, with potential adjustments or extensions.

Here's a breakdown for US Patent 7812505:

Patent Term Adjustments (PTA)

Patent Term Adjustment (PTA) adds days to the term of a patent to compensate for certain delays by the USPTO during prosecution. The USPTO calculates PTA at the time of patent issuance and it is typically included in the Issue Notification Letter. Applicant delays can reduce any awarded PTA.

Based on the Google Patents record for US7812505, the patent does not explicitly state any awarded Patent Term Adjustments on its front page. To get the precise PTA, one would need to access the official patent file wrapper via USPTO's Patent Center.

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 a portion of the patent term lost while awaiting premarket government approval from a regulatory agency, such as the FDA. A PTE cannot exceed five years and the total patent term, including the restoration period, cannot exceed 14 years following agency approval.

US Patent 7812505 is titled "Piezoelectric microspeaker using microelectromechanical systems and method of manufacturing the same." This subject matter (microspeakers) does not fall into the categories of products eligible for PTE under 35 U.S.C. § 156. Therefore, it is highly unlikely that this patent has received any Patent Term Extension.

Continuation Applications

A continuation application is an application for the invention(s) disclosed in a prior-filed copending nonprovisional application. The disclosure must not include any new matter that would constitute new matter if submitted as an amendment to the parent application. It must be filed while the parent application is still pending.

The Google Patents page for US7812505 indicates that it is the direct grant from application number US12/240,138. There are no listed continuation applications for US7812505 within the provided "Other versions" or "Applications Claiming Priority" sections that would suggest subsequent continuation filings from US7812505 itself.

Divisional Applications

A divisional application is a type of continuing application that claims subject matter only disclosed in an earlier, parent application, but with distinct claims. It is typically filed when an examiner requires restriction between two or more independent and distinct inventions claimed in a single application. Like continuation applications, divisional applications must be filed while the parent application is still pending.

Based on the provided information, there are no listed divisional applications for US7812505.

Related Family Members

The "Family has litigation" section on Google Patents lists related applications. In this context, "family" refers to a collection of patent documents that cover the same invention and have at least one common inventor, showing a patent lineage back to a priority date.

For US7812505, the following related family members are identified:

• Application Number: US12/240,138 (the application that led to US7812505B2).
• Publication Number: US20090146527A1 (the pre-grant publication of US12/240,138).
• Korean Priority Application: KR1020070126788A, filed December 7, 2007, which is the priority document for US7812505. This Korean application led to KR100931575B1, also listed in the "Also Published As" section.

Projected Expiration Date

The basic patent term for a U.S. utility patent filed on or after June 8, 1995, is 20 years from the earliest effective filing date. US Patent 7812505 was filed on September 29, 2008, and claims priority to Korean Patent Application No. 2007-126788, filed December 7, 2007. The 20-year term is calculated from the earliest priority date, which is December 7, 2007.

Therefore, the base expiration date would be December 7, 2027.

However, Google Patents itself provides an "Adjusted expiration" date. This date incorporates any Patent Term Adjustment (PTA). For US7812505, Google Patents lists the "Adjusted expiration" date as January 23, 2029. This indicates that there was a Patent Term Adjustment granted to the patent, extending its term beyond the initial 20 years from its priority date.

Therefore, the projected expiration date for US Patent 7812505 is January 23, 2029.
