Synthetic DNA Vectors and Methods of Use
US 11,324,839
Cited by 9 later US patents, top 25% of utility patents granted in 2022 in our data. Protection runs to 2040.
Replicative Minicircle Vectors with Improved Expression
US 10,047,365
The largest patent family in this portfolio, 5 related applications, renewed at every maintenance window due so far. Protection runs to 2033.
E. Coli Plasmid DNA Production
US 9,017,966
Renewed at every maintenance window since the 2015 grant; no more fees are due before its term ends in 2030.
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.
