A tight CPC tells you to read the claim narrowly, and HL Klemove's grant US11679745B2, "Rear-end collision avoidance apparatus and method" (issued June 20, 2023), is about as tight as ADAS claims get: B60T 7/12 (brake-system control responsive to external conditions) and B60T 2210/32. Two braking classes, no perception classes in the headline set — which signals that the claimed novelty is in the braking response, not the sensing that triggers it.
That is a deliberate and defensible scope. Most ADAS attention goes to forward collision warning and automatic emergency braking facing ahead; a claim aimed specifically at the rear-end scenario — the host vehicle being approached from behind, or managing its own following distance to avoid rear-ending — carves out a less-crowded corner. The B60T placement means enforcement reads on braking-actuation behavior, which is testable, rather than on an abstract perception method.
On scope, the independent claim establishes the rear-end avoidance braking; the dependents that specify the triggering conditions and the braking modulation are the moat. Because the claim is anchored in actuation, it sidesteps some of the prior-art density that plagues perception claims, but it must still distinguish over general automatic-braking art. The dependents that tie the braking profile to a specific rear-end geometry are what give it durable teeth.
HL Klemove, a Korean ADAS supplier formed from Mando's autonomy unit, files steadily in driver-assistance braking, and this grant fits that portfolio. Dated June 2023, it reflects the maturation of ADAS beyond the forward-facing basics into more specific collision scenarios. The teardown verdict: a narrow, actuation-anchored grant whose value is precisely its specificity — read the braking-condition dependents, and do not mistake the tight CPC for a weak claim. Narrow and issued often beats broad and pending.
