Patent Term and Family Details for U.S. Patent 6,813,742

Projected Expiration:

The patent has expired. U.S. Patent 6,813,742 was filed on January 2, 2001. Under the patent term of 20 years from the earliest filing date, the patent term would have ended on January 2, 2021. Public records indicate the patent's status is "Expired - Lifetime" with an adjusted expiration date of December 15, 2021. No evidence of Patent Term Adjustment (PTA) or Patent Term Extension (PTE) that would extend the date beyond this has been found.

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

• PTA: There is no indication of any Patent Term Adjustment in the available records. PTA is granted to compensate for delays caused by the USPTO during the patent prosecution process.
• PTE: There is no indication of any Patent Term Extension. PTE is typically granted for patents covering products that undergo a lengthy regulatory review process, such as pharmaceuticals, which is not applicable to this patent's technology area.

Continuity and Related Family Members:

The application for the '742 patent (US 09/681,093) is part of a family of applications that claim priority to the same initial filing date.

• Continuation-in-Part Applications:

  • U.S. Patent 6,799,295 (Application No. 10/248,245): Filed on December 30, 2002, this is a continuation-in-part of the application that led to the '742 patent.
  • U.S. Patent Application Publication No. 2003/0097633 A1 (Application No. 10/065,408): Filed on October 15, 2002, this is also a continuation-in-part of the '742 patent's application. This application was later abandoned.

• Provisional Application: The '742 patent references and claims the benefit of U.S. Provisional Application No. 60/131,516, filed on May 26, 1999.

The existence of these related applications demonstrates a strategy to expand and build upon the technology disclosed in the original 2001 filing. However, the expiration date of the '742 patent is tied to its own filing date, and it has now expired.
