Extensions

US patent 9843786, titled "Transport of stereoscopic image data over a display interface," was granted on December 12, 2017, from an application filed on September 6, 2016. The patent claims priority to an earlier application filed on December 18, 2007.

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

Specific Patent Term Adjustment (PTA) or Patent Term Extension (PTE) amounts for US patent 9843786 were not directly retrievable from the conducted searches of the USPTO database. The USPTO does not calculate expiration dates for patents but provides resources like a downloadable patent term calculator to assist in estimation, which requires specific patent information.

Generally, PTA is granted to utility or plant patents to compensate for certain administrative delays by the USPTO during prosecution, such as failing to issue a first Office Action within 14 months of filing, failing to respond to an applicant's reply within four months, or failing to issue the patent within four months of the issue fee payment. PTA can be reduced by periods of applicant-caused delays.

PTE, under 35 U.S.C. § 156, is available for patents on certain human drugs, food or color additives, medical devices, animal drugs, and veterinary biological products to restore patent term lost during premarket government approval processes. Given the technical nature of US9843786 (stereoscopic image data transport), it is unlikely to be eligible for PTE, as these are typically related to regulatory approval for products like pharmaceuticals.

Continuation and Divisional Applications

The patent text indicates that US9843786 is part of a larger patent family, showing a clear continuity chain:

• Parent Application: US15/256,839 (the direct application for US9843786).
• Earlier Applications/Family Members: US9843786 claims priority to US15/256,839, which itself claims priority to US14/629,642 (now U.S. Pat. No. 9,462,258), and US12/808,685 (now U.S. Pat. No. 9,036,010). These demonstrate a lineage through continuation applications. The earliest priority date for this family is December 18, 2007.

Related Family Members

The patent explicitly lists the following related applications and patents in its priority and related applications sections:

• US15/256,839 (application leading to US9843786)
• US14/629,642 (resulted in US Pat. No. 9,462,258)
• US12/808,685 (resulted in US Pat. No. 9,036,010)
• PCT/IB2008/055305 (international application)
• EP07123461.1 (foreign priority application)

Projected Expiration Date

The standard term for a U.S. utility patent (other than a design patent) issued from an application filed on or after June 8, 1995, is 20 years from the date on which the earliest application for which a benefit is claimed was filed. In the case of US9843786, the earliest priority date is December 18, 2007.

Therefore, without any PTA, the patent term would extend 20 years from December 18, 2007. This would result in an unadjusted expiration date of December 18, 2027.

However, the Google Patents page for US9843786 lists an "Anticipated expiration" date of December 15, 2028. This anticipated expiration date, being later than the unadjusted 20-year term from the earliest priority date, suggests that the patent likely received approximately one year of Patent Term Adjustment (PTA). This difference typically accounts for delays in prosecution by the USPTO. While the exact PTA calculation is not available, the Google Patents information serves as an indicator of the adjusted term.
