Systems and Methods for Igniting Explosives
US 7,987,760
The most cited patent in this portfolio, cited by 26 later US patents, top 25% of utility patents granted in 2011 in our data. Protection runs to 2029.
Multi-Pass Optical System for a Pump Laser
US 8,665,516
Renewed at every maintenance window since the 2014 grant; no more fees are due before its term ends in 2031.
Regenerative Laser Amplifier
US 7,982,947
Renewed at every maintenance window since the 2011 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.
Computed patent terms end on the dates shown. Related patents and pending applications may cover overlapping subject matter.
