Extensions

US patent 12290418, titled "Intraoral device," was filed on September 4, 2024, and issued on May 6, 2025.

Here's a breakdown of its characteristics:

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

• Patent Term Adjustment (PTA): PTA compensates patent owners for delays caused by the USPTO during the prosecution of a utility or plant patent application. The total PTA adds to the standard 20-year patent lifespan. It's granted if the USPTO fails to meet certain deadlines, such as issuing a first office action within 14 months of filing, responding to an applicant's reply within four months, or issuing the patent within 36 months of filing. While the patent description mentions the publication date of US12290418B2 as 2025-05-06, it does not explicitly state the amount of PTA granted. To determine the exact PTA, a direct review of the patent's issue certificate or file wrapper on the USPTO Patent Center would be necessary.
• Patent Term Extension (PTE): PTE is available for patents on certain products, like human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products, to restore patent term lost due to the premarket government approval process by a regulatory agency (e.g., FDA). The patent describes an "intraoral device," which could potentially qualify as a medical device for PTE purposes. However, the patent document for US12290418 does not indicate if any PTE has been applied for or granted.

Continuation and Divisional Applications:

• Continuation Applications: A continuation application is a second application for the same invention claimed in a prior non-provisional application and is filed before the original application is patented or abandoned. It allows the applicant to pursue additional claims to the same subject matter.
• Divisional Applications: A divisional application is a later application for a distinct invention carved out of an earlier application, filed when the USPTO determines the original application contains more than one invention.

The patent text for US12290418 explicitly states, "The present application is a continuation and claims the priority benefit of U.S. patent application Ser. No. 18/679,097 filed May 30, 2024, which is a continuation and claims the priority benefit of U.S. patent application Ser. No. 18/217,304 filed Jun. 30, 2023, now U.S. Pat. No. 12,011,329, which is a continuation and claims the priority benefit of U.S. patent application Ser. No. 14/228,057 filed Mar. 27, 2014, now U.S. Pat. No. 11,744,686, which is a continuation and claims the priority benefit of U.S. patent application Ser. No. 14/100,323 filed Dec. 9, 2013, now U.S. Pat. No. 8,911,232, which claims the priority benefit of U.S. provisional patent application No. 61/734,939 filed Dec. 7, 2012, the disclosures of which are incorporated herein by reference." This confirms that US12290418 is a continuation application stemming from a long chain of prior applications, ultimately tracing back to a priority date of December 7, 2012.

Related Family Members:
The patent lists the following related applications from which it claims priority:

Additionally, the Google Patents page lists several other family applications, including design patents and other utility patents, all sharing the priority date of 2012-12-07. These include:

• US29/477,888 (USD809660S1)
• US29/477,887 (USD876627S1)
• US29/491,367 (USD734851S1)
• US29/780,960 (USD1033650S1)
• US29/782,645 (USD962439S1)
• US29/782,638 (USD962438S1)
• US19/199,177 (US20250275841A1)

Projected Expiration Date:
The anticipated expiration date of a U.S. patent is generally 20 years from the earliest effective filing date of the non-provisional application in its family, plus any Patent Term Adjustment (PTA) and excluding any periods of applicant-caused delay or terminal disclaimers. Patent Term Extensions (PTE) can further extend this for certain products requiring regulatory approval.

Given the priority date of December 7, 2012, the base 20-year term would expire on December 7, 2032. The Google Patents entry for US12290418B2 lists an "Anticipated expiration" date of 2033-12-09. This suggests that there has been approximately 1 year and 2 days of Patent Term Adjustment (PTA) applied to the patent term. Without direct access to the USPTO file wrapper for US12290418, the exact calculation of this PTA cannot be confirmed, but the cited "Anticipated expiration" date indicates its inclusion. There is no indication of any Patent Term Extension (PTE) for this patent.
