Minimally Color Changing N-Type Ion Storage Layers, Electrochromic Devices Made Therewith, and Related Methods
US 10,962,856
The earliest of the three still in force, granted 2021 and renewed since. Its term ends first, in 2039.
Method for Fabricating Solid State Electrochromic Device, Solid State Electrochromic Device and Its Applications
US 10,921,673
A family of 22 related applications built on the 2021 grant. Protection runs to 2039.
Thermally Stable and Solvent-Resistant Conductive Polymer Composites
US 11,773,213
The newest of the three, granted 2023. It anchors the portfolio to 2040, later than anything else here. A terminal disclaimer caps this term to an earlier patent's.
Fee deadlines
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 Feb 28, 2027The maintenance fee for Disulfide-Containing Monomer, Its Reduced Form, and Its Derivate, Method to Synthesize the Same, and Polymer Containing the Same (US 11,739,179) comes due Feb 28, 2027. Unpaid by Aug 30, 2027, it lapses early.
- 1 fee due Apr 3, 2027The maintenance fee for Thermally Stable and Solvent-Resistant Conductive Polymer Composites (US 11,773,213) comes due Apr 3, 2027. Unpaid by Oct 4, 2027, it lapses early.
- 3 fees due Jul 9 to 23, 2027 · next Jul 9
- 1 fee due Aug 27, 2027The maintenance fee for VANADIUM OXIDE WITH A FORMULA OF VOx AS CHARGE BALANCING MATERIAL FOR ELECTROCHROMIC DEVICES (US 11,914,260) comes due Aug 27, 2027. Unpaid by Feb 28, 2028, it lapses early.

Sources and methods
Compiled from USPTO application file histories, grants and recorded assignments, with the company's own names reviewed by hand. How this record was built
Portfolio grouped automatically from ownership conveyances to the names matched to this company, usually every name that begins with its own, so it counts patents an affiliate holds; each list row names the holder of record. Security interests are excluded and ambiguous records are not reviewed by hand.
Fee due within 90 days marks a patent with a maintenance fee due within 90 days of the date this page was computed and not yet recorded paid, so it can end earlier than the bar shows. A fee left unpaid ends the patent at the close of the six month grace period that follows its due date, not on the due date itself. It is not a prediction that the fee will be missed.
Computed patent terms end on the dates shown. Related patents and pending applications may cover overlapping subject matter.
