Extensions

US patent 8013568 was filed on May 8, 2006, and issued on September 6, 2011. The statutory patent term for applications filed after June 8, 1995, is 20 years from the earliest effective filing date.

Based on the information available:

• Patent Term Adjustments (PTA): The Google Patents entry for US8013568 indicates an adjusted expiration date of May 27, 2028. This adjustment typically accounts for delays incurred by the USPTO during prosecution. Specific details on the PTA calculation (e.g., A, B, C delays, or applicant delays) are not explicitly provided in the snippets, but the existence of an adjusted expiration date confirms that PTA was applied.

• Patent Term Extensions (PTE): There is no indication in the provided information that US8013568 has received a Patent Term Extension (PTE). PTEs are typically granted for patents covering pharmaceutical products, medical devices, or other products that undergo lengthy regulatory review processes (e.g., FDA approval). The patent's subject matter (contact-less charging for batteries) does not fall under these categories, making a PTE unlikely.

• Continuation Applications: The Google Patents page for US8013568 lists "US11/997,272" as the application number, with "US99727206A" also listed, which could refer to a related application or a different format of the same application. The patent claims priority from PCT/KR2006/001713, filed on May 8, 2006, and from Korean Applications 10-2005-69871 (filed July 29, 2005) and 10-2006-38960 (filed April 28, 2006). These indicate a family of related applications.

• Projected Expiration Date: The Google Patents information for US8013568 explicitly states "Active, expires 2028-05-27" and "Adjusted expiration 2028-05-27". This date reflects the 20-year term from the earliest effective filing date (May 8, 2006, from PCT/KR2006/001713) plus any Patent Term Adjustment (PTA). The ex parte reexamination, which added new claims 25-58 and amended others, does not inherently alter the overall expiration date of the patent.
