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 Dec 11, 2026The maintenance fee for Laterally Diffused Metal Oxide Semiconductor Transistors for Radio Frequency Power Amplifiers (US 10,319,815) comes due Dec 11, 2026. Unpaid by Jun 11, 2027, it lapses early.
- 1 fee due Oct 28, 2027The maintenance fee for RF Amplifier with Conductor-Less Region Underlying Filter Circuit Inductor, and Methods of Manufacture Thereof (US 10,637,400) comes due Oct 28, 2027. Unpaid by Apr 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.
