Polymeric Coating for the Protection of Objects
US 8,309,627
Cited by 84 later US patents, top 10% of utility patents granted in 2012 in our data, and renewed at 3 of 3 maintenance windows. Protection runs to 2028. 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.
Method of Aerogel Synthesis
US 9,206,298
Cited by 42 later US patents, top 25% of utility patents granted in 2015 in our data, and renewed at every maintenance window due so far. Protection runs to 2034.
Methods for Reducing or Eliminating Defects in Polymer Workpieces
US 7,785,517
Renewed at every maintenance window since the 2010 grant; no more fees are due before its term ends in 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.
- 1 fee due Jun 8, 2027The maintenance fee for Method of Aerogel Synthesis (US 9,206,298) comes due Jun 8, 2027. Unpaid by Dec 8, 2027, 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.
Computed patent terms end on the dates shown. Related patents and pending applications may cover overlapping subject matter.
