United States Patent 7,776,007: Scope, Claim-by-Claim Analysis, and Landscape Implications
What does US 7,776,007 actually claim?
US Drug Patent 7,776,007 claims a needle-free injector device with a multi-stage safety and readiness sequence. The core claim language ties together (i) a cap that must be removed, (ii) a latch that blocks movement until a user action, and (iii) a lever-and-collar mechanism that converts user input into latch movement from a latch safe state to a latch ready state. Dependent claims then add layers: an additional safety that blocks trigger, a blocked geometry, and a user-facing button delivery function, plus lever actuation constraints tied to cap removal.
From the claim set provided, the invention’s scope is centered on interlocks that ensure the injector cannot enter a ready or triggering mode unless multiple mechanical conditions are satisfied.
Claim 1: What is the independent “device” core?
Claim 1 defines the baseline device architecture and establishes the main claim boundaries.
Required elements (must all be present)
- Needle-free injector with an injection orifice.
- Cap covering the injection orifice, with a placement condition that:
- the cap must be removed before the injector can be placed in ready position.
- Mechanism for changing injector states:
- from safe position to ready position to triggering position.
- Latch-based safety transfer:
- “the mechanism for changing the injector from the safe position to the ready position comprises a latch.”
- Latch positioning transfer:
- a mechanism moves the latch from a latch safe position to a latch ready position.
- Pin-driven latch actuation:
- the latch-moving mechanism includes:
- a pin (called “a in” in the claim text received, treated as a pin/guided element),
- and a means for actuating the pin.
- upon actuating the pin, the pin pushes the latch from latch safe to latch ready.
- Lever and collar translation:
- the means for actuating the pin includes:
- a lever movable from lever safe to lever ready position,
- and a collar at least partially encircling the injector.
- actuating the lever moves the collar.
- the collar moves the pin against the latch.
- Coupled state gating:
- the cap removal condition ties into when the lever can be moved (explicit in dependent claims; implied by claim 1’s “cap must be removed before … ready position”).
Scope interpretation
Claim 1 is broad on the functional relationship between parts:
- It does not limit the latch to a specific geometry.
- It does not limit the pin type beyond being actuated to push the latch.
- It does not restrict the collar to a specific coupling method beyond “at least partially encircling the injector” and translating the pin via lever action.
Hard boundary: the safety-to-ready transition must be achieved using a lever-driven collar that actuates a pin to push a latch from safe to ready, in a device that also includes a cap required for ready-state entry.
Claim 2: What additional constraint is added to prevent triggering?
Claim 2 adds an additional safety mechanism that prevents triggering, plus a coupling rule to the lever action.
Additional required elements
- A further safety mechanism “to prevent triggering of the injector.”
- The claim specifies that:
- moving the lever from lever safe to lever ready moves the collar, and
- the additional safety mechanism is disengaged when the collar moves under the action of lever movement.
Scope impact
Claim 2 tightens the “ready-to-trigger” transition:
- It requires an extra blocking safety between ready and triggering.
- It requires disengagement of that safety based on the lever-driven collar motion.
An accused device must therefore show:
- lever movement changes collar position,
- collar movement disengages an additional trigger-blocking safety.
Claim 3: How does the claim constrain the additional safety mechanism?
Claim 3 specifies a configuration for the additional safety mechanism:
- the additional safety mechanism is “configured in a block shape”
- to prevent triggering by blocking relative movement of components that cause the device to go from ready to triggering.
Scope impact
This is a shape-limited dependent claim.
- If an accused device uses an additional trigger-blocking mechanism not resembling a “block shape,” it may avoid Claim 3 even if it meets Claim 2’s general disengagement requirement.
Claim 4: What user interface feature is claimed?
Claim 4 adds a delivery actuation interface:
- moving of the lever exposes a button
- pressing the button causes delivery.
Scope impact
This creates a second explicit functional pathway:
- lever motion must both (i) manage safety interlocks through the collar/pin/latch system and (ii) enable a user-facing button that triggers delivery.
If the device uses a different actuation UI (for example, a slide or direct firing mechanism) without exposing a button, it may avoid Claim 4 while still potentially falling within Claim 1-3.
Claim 5: Lever actuation is conditional on cap removal; rotation places ready
Claim 5 adds two strong constraints:
- “the lever is movable only after the cap is removed”
- “rotating the lever places the injector in the ready position.”
Scope impact
This claim ties lever movement to the cap state explicitly:
- It does not merely say cap must be removed before ready (Claim 1), it states lever movement is physically prevented until cap removal.
It also adds an actuation mode limitation:
- lever action is by rotation (not linear sliding, squeezing, etc.).
Devices using a lever that pivots only, or that rotates without being constrained by cap removal, may be outside Claim 5.
Claim 6: Lever end attached to cap; lever base actuates safety mechanism
Claim 6 is a structural attachment claim:
- “an end of the lever is attached to the cap”
- “a base of the lever actuates a safety mechanism.”
Scope impact
This ties lever and cap mechanically:
- The cap removal is not just an environmental condition; it participates in the lever structure.
If a device requires cap removal but does not mechanically attach the lever end to the cap, Claim 6 is harder to meet.
Claim 7: Cap removal exposes lever end; lever pivots to ready/deliver
Claim 7 (as received) contains internal phrasing inconsistencies (“pivoted” repeated, “ready position to deliver state”), but the substantive constraints are clear:
- when cap is removed, an end of the lever is exposed
- allowing the lever to pivot into placement for ready-to-deliver state
Scope impact
Claim 7 limits lever movement mode to pivoting in response to cap removal.
- This differs from Claim 5’s “rotating the lever.”
- A device could satisfy one dependent claim and not the other depending on actual motion type and claim construction.
Claim 8: Additional safety mechanism disengaged when lever is actuated
Claim 8 is another dependent claim parallel to Claim 2:
- it includes “an additional safety mechanism to prevent triggering”
- and requires that the additional safety mechanism is disengaged when the lever is actuated.
Scope impact
Claim 8 is an alternative dependency strategy:
- Claim 2 ties disengagement to collar movement specifically.
- Claim 8 ties disengagement to lever actuation generally (still consistent with collar movement, but not as explicitly constrained as Claim 2).
Where does the scope sit relative to the needle-free injector market?
Based on the claim set, US 7,776,007 aligns to a segment of needle-free delivery devices characterized by:
- stateful mechanical interlocks (safe vs ready vs triggering),
- cap-based exclusion preventing unintended activation,
- user action via lever driving internal interlock motion (collar/pin/latch),
- and trigger-blocking safety that must be disengaged before delivery.
This claim structure is typical of devices that prioritize:
- shipping/handling safety (cap present),
- user readiness preparation (lever-to-ready transfer),
- and firing only after additional interlocks are cleared (additional safety mechanism disengaged).

Patent landscape analysis (competitive positioning by claim theme)
No competitor or citation dataset is provided in the prompt, and the request does not include bibliographic metadata for US 7,776,007 (assignee, filing date, inventors, CPC classifications, or cited references). Under the constraints, the landscape can only be constructed from the claim themes in your text.
Still, the claim themes yield actionable landscape partitions for clearance and design-around planning:
Landscape partition A: Cap-gated readiness
Claim anchor: cap must be removed before ready (Claim 1) and lever movement may be constrained until cap removal (Claim 5-7).
Competitive risk zone: devices with:
- a cap that blocks firing and
- an internal lever mechanism that cannot be actuated until cap removal.
Landscape partition B: Lever-collar-pin-latch chain
Claim anchor: lever moves collar around injector; collar actuates pin that pushes latch safe to ready (Claim 1).
Competitive risk zone: internal mechanism using:
- a circumferential collar translating a pin,
- to move a latch between safe and ready states.
Landscape partition C: Additional trigger-block safety
Claim anchor: separate safety mechanism prevents triggering and is disengaged by collar or lever action (Claim 2, Claim 8), with a block-shaped variant (Claim 3).
Competitive risk zone: devices that:
- include an additional trigger-block element beyond latch safe-to-ready.
Landscape partition D: UI and motion mode (button exposure; rotate vs pivot)
Claim anchor: lever exposes a button (Claim 4); lever motion is rotation (Claim 5) or pivoting (Claim 7).
Competitive risk zone: design matches user interaction and lever motion constraints.
Practical implications: how claims shape design-around options
This patent’s scope is mechanism-specific, so design-arounds tend to focus on breaking at least one required element in the Claim 1 chain or severing claim dependencies.
Design-around levers aligned to Claim 1
- Replace lever-collar-pin-latch transfer chain
- If readiness does not use a collar encircling the injector to drive a pin pushing a latch, the Claim 1 core may be avoided.
- Eliminate cap-as-necessary condition for ready entry
- If the device allows ready-state placement without cap removal (or uses a different gating element), the Claim 1 cap removal condition may not be met.
- Change the actuation pathway to latch
- If latch safe-to-ready occurs through a different actuation mechanism not involving pin pushing, Claim 1 may not be satisfied.
Design-around levers aligned to dependent claims
- To avoid Claim 2/8: keep additional trigger-preventing safety engaged through lever actuation, or disengage it through a mechanism not tied to collar movement/lever actuation.
- To avoid Claim 3: use a non-block-shaped additional safety preventing relative movement (e.g., a detent, spring-biased pawl, or latch geometry not describable as a block).
- To avoid Claim 4: use a different firing interface than a button exposed by lever motion.
- To avoid Claim 5: allow lever movement before cap removal, or use a non-rotational lever actuation.
- To avoid Claim 6: avoid mechanical attachment of lever to cap.
- To avoid Claim 7: use a motion mode inconsistent with pivot-only placement tied to cap removal.
Key Takeaways
- US 7,776,007 is scoped around a cap-gated, stateful needle-free injector using a lever-to-collar-to-pin-to-latch mechanism for safe-to-ready transfer.
- Dependent claims add a separate trigger-preventing safety disengaged by lever/collar motion, plus a block-shaped safety variant.
- Further tightening appears through button exposure (Claim 4) and lever motion/cap linkage constraints: rotation (Claim 5), cap-attached lever end (Claim 6), and pivoting after cap removal (Claim 7).
- Clearance/design-around effort should prioritize breaking the Claim 1 mechanical chain (or cap gating), then selectively addressing dependent claim triggers (additional safety disengagement, UI exposure, and motion mode).
FAQs
1) Does Claim 1 require the device to have all three positions: safe, ready, and triggering?
Yes. Claim 1 states a mechanism changes the injector from safe to ready to triggering positions, with latch control specifically covering safe-to-ready.
2) Is the “additional safety mechanism” required only in dependent claims?
Yes. Claim 1 does not require the additional trigger-preventing safety. Claims 2, 3, and 8 add it.
3) What single feature most directly drives Claim 1 infringement risk?
The coupled mechanism where the lever moves a collar that actuates a pin to push a latch from latch safe to latch ready.
4) Can a device avoid Claim 5 while still meeting Claim 4?
Yes. Claim 5 specifically adds constraints on lever movement timing (only after cap removal) and rotation to reach ready. Claim 4 only requires lever motion that exposes a button to cause delivery.
5) Is “block shape” mandatory for the trigger-blocking safety?
Only for Claim 3. Claim 2 and 8 require an additional safety preventing triggering but do not require the block-shape configuration.
