Extensions

US Patent 7651245, titled "LED light fixture with internal power supply," has a projected expiration date of September 22, 2027.

Regarding patent term adjustments (PTA) and patent term extensions (PTE), the patent states that its term is "extended or adjusted under 35 U.S.C. 154(b) by 101 days." PTA can extend the term of a patent to compensate for certain delays caused by the USPTO during prosecution, such as failing to issue an office action within 14 months of filing, or failing to issue a patent within 36 months from the filing date. PTE, on the other hand, can extend the patent term for certain types of patents, like pharmaceuticals, to account for regulatory review periods.
