The weekly pass
Useful leads, with the record still attached.
A lapse is a signal to investigate. Each opportunity keeps the dates, drawing, and family context close by.
02 / READ
Makeability at a glance
Summaries grounded in the abstract and first claim, primary drawings, key dates, and a 1–10 score weighing materials, assembly, process, electronics, and regulation.
03 / WATCH
Family and status checks
Continuity data can flag related patents still in force, while later fee events are checked for reinstatement.
A deliberate scope
Product classes with a path to the bench.
The first-pass filter favors tangible products a smaller operation could plausibly print, machine, mold, or assemble.
Included areas
Household
Pet
Garden
Carry & organize
Mounts & fasteners
Fitness
Airflow
Outside the first pass
Medical devices, electronics and software, chemistry, and toys are excluded from the initial filter because their regulatory or technical burdens need a different review.

Before you build
Lapsed does not mean cleared.
A patent recorded as expired for nonpayment is not a guarantee that a product is free to make or sell. A family check does not clear design patents or third-party improvements. Verify current rights and get appropriate advice before commercializing an idea.
