Maintenance fees fall due 3.5, 7.5 and 11.5 years after grant. A missed fee ends a patent at the end of the six month grace period that follows, not on the due date.
- 1 fee due Mar 5, 2027The maintenance fee for Method for reducing the diameter of a x-ray tube through recessing of the vacuum port (US 11,749,490) comes due Mar 5, 2027. Unpaid by Sep 7, 2027, it lapses early.
- 1 fee due Apr 3, 2027The maintenance fee for Methods and means for measurement of the water-oil interface within a reservoir using an x-ray source (US 11,774,632) comes due Apr 3, 2027. Unpaid by Oct 4, 2027, it lapses early.
- 2 fees due Aug 6 to 25, 2027 · next Aug 6
