Coding of a Spatial Sampling of a Two-Dimensional Information Signal Using Sub-Division
US 10,771,822
Cited by 212 later US patents, top 1% of utility patents granted in 2020 in our data. Protection runs to 2032. A terminal disclaimer is on file and its reference is not resolved, so no cap is applied and the date may move earlier, never later.
Multitree Subdivision and Inheritance of Coding Parameters in a Coding Block
US 10,038,920
Cited by 176 later US patents, top 1% of utility patents granted in 2018 in our data, and renewed at every maintenance window due so far. Protection runs to 2032. A terminal disclaimer is on file and its reference is not resolved, so no cap is applied and the date may move earlier, never later.
Region Merging and Coding Parameter Reuse via Merging
US 10,621,614
Cited by 196 later US patents, top 1% of utility patents granted in 2020 in our data. Protection runs to 2032.
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.

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.
