Drawing Apparatus
US 8,175,402
The most cited patent in this portfolio, cited by 29 later US patents, top 25% of utility patents granted in 2012 in our data. Protection runs to 2031.
Laser Direct Imaging Apparatus
US 7,969,636
Cited by 25 later US patents, top 25% of utility patents granted in 2011 in our data, and renewed at 3 of 3 maintenance windows. Protection runs to 2030.
Method and Apparatus for Driving Semiconductor Lasers, and Method and Apparatus for Deriving Drive Current Patterns for Semiconductor Lasers
US 7,970,029
Renewed at every maintenance window since the 2011 grant; no more fees are due before its term ends in 2026. A terminal disclaimer caps this term to an earlier patent's.
Fee deadlines

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.
