US Patent 10,179,216: Scope of Claims and US Nasal-Delivery Device Landscape
What does US 10,179,216 claim cover?
US 10,179,216 claims a hand-held nasal delivery device with a specific hand-grip geometry and a delivery workflow driven by manual actuation through an actuation member. The invention is framed around (i) the structural combination of a nasal delivery unit and mouth exhalation, and (ii) the grip section geometry that promotes correct orientation during use.
Claim 1 (core device claim)
Claim 1 requires all of the following elements in one device:
- Nasal delivery device with:
- Housing
- Nosepiece configured to fit to a nasal cavity
- Mouthpiece configured for exhalation through the mouth
- Substance supply unit that includes:
- Actuation member extending from one end of the housing
- Manual actuation to deliver substance to the nasal cavity
- Housing architecture:
- Housing includes main body section and grip section
- Grip section structure (the distinguishing limitation cluster):
- Grip section includes:
- First part with first and second projecting grip elements
- User grips housing to actuate the actuation member
- Second part disposed between main body section and the first part
- Provides a recess formed on an outer surface of the housing
- Recess extends around the periphery of the housing
- The first and second projecting grip elements
- Project to opposite sides of the housing
- Have no intermediate elements between them
- Functional outcome (orientation)
- “Whereby the recess promotes proper orientation of the delivery device in a hand” of the user
Interpretation for scope: Claim 1 is not just a general nasal inhalation device. It is a combination claim that ties together an exhale-driven nasal delivery mechanism (nosepiece + mouthpiece + actuation member) with a specific ergonomic grip geometry (paired projecting grips on opposite sides, no intermediate elements, and a circumferential recess that positions the user’s fingers).
Claim 2 (narrowing limitation)
- Main body section is an elongate section.
Claim 3 (narrowing limitation)
- First and second projecting grip elements are radially aligned with the mouthpiece.
What does Claim 4 cover (method claim scope)?
Claim 4 is a method of delivering substance to a nasal cavity that incorporates the same device structure from Claim 1 and adds a defined user-hand placement step.
Claim 4 (core method claim)
Method steps include:
- Providing a nasal delivery device comprising the Claim 1 structure
- Fitting the nosepiece to the nasal cavity
- Locating the mouthpiece in the mouth
- Gripping the housing such that:
- fingers are located in the recess
- positioned at approximately opposite sides of the housing
- adjacent the first and second projecting grip elements
- thereby promoting proper orientation in the hand to operate the device
Interpretation for scope: Claim 4 explicitly requires the user’s finger placement relative to the recess and grip elements. This is a real-world execution limitation, not just “configuration in the abstract.”
Claim 5 (narrowing)
- Main body section is an elongate section.
Claim 6 (narrowing)
- First and second projecting grip elements are radially aligned with the mouthpiece.
How broad is infringement risk within the claim architecture?
Claim 1 is broad on the delivery concept (nasal delivery with mouth exhalation and manual actuation) but narrow on the grip geometry. In practice, the strongest infringement lever is the grip section, because it includes multiple co-dependent structural constraints:
Grip section constraints in Claim 1
A potential infringer would have to match all of the following, not just one:
- Recess
- formed on an outer surface
- extends around a periphery of the housing
- Two projecting grip elements
- on a first part
- project to opposite sides of the housing
- are paired with no intermediate elements
- Orientation function
- the recess promotes proper orientation (function tied to structure)
Because Claim 1 uses “comprising,” missing elements are allowed only if they do not remove the required elements. The gripping geometry, however, is part of the required combination, so a design that replaces the recess-with-circumferential-periphery orientation with a different finger feature is the most likely to fall outside.
What design-arounds are most likely to avoid Claim 1?
Based strictly on claim language, the most direct non-infringing routes are structural differences that break one of the key required limitations:
- Replace the circumferential periphery recess with a non-circumferential recess (does not extend around the periphery)
- Replace paired opposite-side projections with:
- three or more projections
- or an arrangement with intermediate elements between the “first” and “second” projecting grip elements
- Move away from the “no intermediate elements” constraint by adding intermediate grip features or continuous textured surfaces that constitute “intermediate elements”
- Remove or change the manual actuation member concept (if actuation is not manual from the housing end as claimed)
These are claim-construction levers driven by the explicit structure recited.
How does the method claim broaden or narrow the device claim?
Method Claim 4 tracks the device and then tightens execution via finger placement.
Claim 4 adds an operational limitation
A device that is structurally the same as Claim 1 could still avoid Claim 4 if the method is not performed in the specified way (fingers placed in the recess, approximately opposite sides, adjacent grip elements to promote orientation). That matters in enforcement where the alleged infringer’s marketing or instructions drive (or fail to drive) that specific use.
Practical takeaway
- Device enforcement is typically easier than method enforcement unless usage instructions and user behavior align with the claim’s specific finger placement step.
- Method exposure increases when packaging, IFUs, or training explicitly instruct users to grip in a way that places fingers into the circumferential recess adjacent to the paired grips.
What is the patent landscape around Claim 1’s combination?
Claim 1 combines three functional themes that recur in the nasal delivery art:
- Nasal delivery devices with exhalation through a mouthpiece
- Manual actuation mechanisms that prime or dispense
- Ergonomic hand-grip features that orient the device correctly during use
In the US market, the competitive landscape typically includes:
- drug-device systems where dose delivery depends on user actuation and/or inhalation/exhalation coordination
- competing nasal inhalers that differ in actuation mechanics and interface geometry
- devices with anti-misuse orientation features (often keyed to prevent wrong-hand orientation or misalignment)
Landscape partition keyed to the claim’s “distinguishing” feature
The likely “crowded” area is the first theme (nasal delivery + mouthpiece exhalation + actuation). Many products address misplacement through mechanical stops, shields, or alignment tabs.
Claim 1’s differentiator is the grip section:
- a circumferential recess around the periphery of the housing
- paired opposite-side grip projections with no intermediate elements
- claimed to promote correct device orientation in hand
In enforcement terms, the landscape separates into:
- High overlap on delivery mechanics (nosepiece + mouthpiece + manual actuation)
- Lower overlap on the specific grip geometry (recess around periphery + paired opposite grips with no intermediate elements)
This means the competitive threat depends less on whether the device delivers nasal substance and more on whether it replicates the specific hand interface geometry.
What would be the typical scope of collateral innovation around this patent?
Across nasal device R&D programs, follow-on engineering tends to vary one of the three clusters below:
A. Actuation and flow path changes
- Different actuation members (twist, slide, squeeze, press)
- Different internal reservoirs and metering
- Different exhalation/inhalation fluid dynamics
These may avoid Claim 1 if they break the manual actuation structure as claimed.
B. Nosepiece interface changes
- Different sealing geometries
- Different nozzle shapes
- Different nosepiece insertion depths
These may preserve Claim 1 if the grip geometry remains unchanged.
C. Hand-grip and orientation changes (most relevant)
Companies commonly adjust:
- grip textures
- finger rests
- circumferential or partial recesses
- side ribs or wings to ensure alignment
Claim 1 pushes hard on the circumferential periphery recess and the paired opposite-side projections without intermediate elements, so competitors may redesign finger interfaces to deviate.
Claim-by-claim business implications
If you are a device manufacturer
- Your main exposure to Claim 1 is whether your hand interface matches the recess and paired grip geometry.
- Your main defense is the engineering deviation of:
- circumferential-periphery recess,
- opposite-side paired projections,
- and the “no intermediate elements” constraint.
If you are an IFU-driven brand owner
- Method Claim 4 exposure rises if use instructions and packaging prompt a grip that places fingers in the recess on opposite sides adjacent to the projections.
If you are an investor assessing device defensibility
- Defensibility concentrates in the ergonomic orientation feature rather than in generic nasal delivery concepts, based on the claim language.
Key Takeaways
- US 10,179,216 Claim 1 is a nasal delivery device claim anchored on manual actuation plus exhale through a mouthpiece, but the primary distinguishing scope is the grip section geometry: a recess extending around the periphery and paired opposite-side projecting grip elements with no intermediate elements, positioned to promote proper hand orientation.
- Claim 2 and 3 narrow Claim 1 by requiring an elongate main body and radial alignment of grip elements with the mouthpiece.
- Claim 4 adds a method step requiring users to place fingers in the recess adjacent to the paired grip elements to promote proper orientation.
- The patent landscape risk is highest where competitors replicate the specific finger-interface geometry, not merely where they deliver drugs nasally.
FAQs
1) What is the single most critical limitation in US 10,179,216?
The grip section’s combination of a recess that extends around the periphery plus two projecting grip elements on opposite sides with no intermediate elements, configured to promote correct orientation.
2) Does Claim 1 require a specific drug formulation?
No. The claim is device- and use-structure focused and recites delivering a “substance” without limiting the active ingredient.
3) Can a competitor avoid Claim 4 by changing user instructions?
Potentially. Claim 4 requires a specific finger placement relative to the recess and projecting grips. If use instructions do not drive that placement, method infringement risk can decrease.
4) Is Claim 3 a substantial narrowing of Claim 1?
Yes. It requires the projecting grip elements to be radially aligned with the mouthpiece, tightening allowable geometry.
5) What design changes most directly break claim scope?
Changes that remove or alter the circumferential-periphery recess, introduce intermediate grip elements between the paired projections, or change the manual actuation/member arrangement so it no longer matches the claimed structure.
