Nanopore Biosensors for Detection of Proteins and Nucleic Acids
US 11,761,956
Cited by 26 later US patents, top 5% of utility patents granted in 2023 in our data. Protection runs to 2034. 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.
Mono- or Di-Substituted Indole Derivatives As Dengue Viral Replication Inhibitors
US 10,696,632
Cited by 22 later US patents, top 10% of utility patents granted in 2020 in our data. Protection runs to 2036.
Via First Plus via Last Technique for Ic Interconnects
US 7,939,926
Cited by 92 later US patents, top 10% of utility patents granted in 2011 in our data, and renewed at 3 of 3 maintenance windows. Protection runs to 2028.
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.
