II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,756,955 - "Inflatable Pad and Methods for Using Same"
Issued September 12, 2017
The Invention Explained
- Problem Addressed: The patent describes conventional camping pads as having disadvantages, including being difficult to inflate, heavy, and providing uniform cushioning that does not account for the body's specific support needs. Additionally, contact with the ground can lead to heat loss. (’955 Patent, col. 1:21-55).
- The Patented Solution: The invention is an inflatable pad designed to reduce weight and the volume of air needed for inflation ("fill volume") by incorporating "non-supporting regions." These regions, which can be cutouts or simply areas with less vertical thickness, are strategically placed where a user’s body requires less support, such as the legs or mid-back. This contrasts with "primary support regions," such as those for the hips and shoulders, which are more robustly supported. This design aims to provide targeted comfort and better insulation with less material and effort. (’955 Patent, col. 2:1-14, 5:5-13).
- Technical Importance: This approach seeks to optimize the trade-off between comfort, weight, and packability, a central engineering challenge in the market for high-performance outdoor gear. (’955 Patent, col. 2:1-14).
Key Claims at a Glance
- The complaint asserts independent claims 1, 12, and 16, along with multiple dependent claims. (Compl. ¶23).
- Independent Claim 1 includes these essential elements:
- A frame of two material sheets joined by bond lines to form fluidly connected air inflatable support members.
- A valve for inflation.
- A pattern of "non-supporting regions" defined by non-inflating regions, bond lines, and/or cutouts.
- At least some bond lines comprising a "rounded first end," a "flared second end," and a "transitioning portion," with the flared end being wider than the rounded end.
- A specific ratio of "fill volume/pad area" in the range of 0.4-4.0 ml/cm².
- The complaint reserves the right to assert claims 2-7, 9, 10, 13, and 15-19. (Compl. ¶23).
U.S. Patent No. 9,936,814 - "Inflatable Pad and Methods for Using Same"
Issued April 10, 2018
The Invention Explained
- Problem Addressed: As with its parent patent, the ’814 Patent addresses the need for lightweight, comfortable, and easily inflatable camping pads. (’814 Patent, col. 1:24-58).
- The Patented Solution: The solution again involves an inflatable pad constructed from two sheets of material. This patent focuses more on the geometric properties of the "bond lines" (welds) and the resulting "fluidly coupled cells." The invention describes how elongating the bond lines and having at least one end increase in width can create a desired support structure. The specification also notes that specific bond line configurations can be used to reduce torsion in the pad when it is inflated. (’814 Patent, col. 2:1-25, 2:45-50).
- Technical Importance: The invention refines the design of lightweight inflatable pads by focusing on the specific geometry of the welds to control structural properties like torsional stability and user support. (’814 Patent, col. 2:45-50).
Key Claims at a Glance
- The complaint asserts independent claims 1, 8, and 15, along with multiple dependent claims. (Compl. ¶34).
- Independent Claim 1 includes these essential elements:
- A frame of two material sheets joined by a plurality of "elongated" bond lines.
- At least one end of each bond line "increases in width."
- A plurality of "fluidly coupled cells" defined between the bond lines, with the cells having a first and second width.
- A valve in fluid communication with the cells.
- The complaint reserves the right to assert claims 2, 7, 9, 11, 14, and 17-19. (Compl. ¶34).

IV. Analysis of Infringement Allegations
’955 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a frame comprising a first sheet of material joined to a second sheet of material at a plurality of bond lines to form a plurality of fluidly connected air inflatable support members... | The accused pad is made of two sheets joined at bond lines, forming inflatable support members in between. | ¶23 | col. 4:6-14 |
| a first valve coupled to the frame and in fluid communication with the air inflatable support members for inflation thereof; | The accused pad includes a valve that allows the pad to be inflated. A photograph shows the valve on the accused product. (Compl. ¶23). | ¶23 | col. 4:1-4 |
| wherein the frame includes a pattern of non-supporting regions defined by noninflating regions, the plurality of bond lines, and/or cutouts of the first and second sheets; | The accused pad's frame includes non-supporting bond lines that connect the two sheets, arranged in a geometric pattern. | ¶23 | col. 4:15-22 |
| wherein at least some of the bond lines comprise a rounded first end having a diameter, a flared second end having a width, and a transitioning portion therebetween, | The bond lines are alleged to be "generally x-shaped with flared ends," and that each of these has four ends that are "rounded and flared." A photograph purports to show these features on an uninflated portion of the accused pad. (Compl. ¶23). | ¶23 | col. 8:41-54 |
| wherein the frame has a ratio of a fill volume/pad area in a range from about 0.4-4.0 ml/cm² where the fill volume consists of the volume of air contained within the air inflatable support members at a pressure of 2 psi. | Based on an estimated fill volume and pad area calculations derived from the Amazon product listing, the complaint alleges the ratio falls within the claimed range (between 0.80 and 1.1 ml/cm²). | ¶23 | col. 8:51-54 |
’814 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a frame comprising: a first sheet of material and a second sheet of material joined at a plurality of bond lines... | The accused pad is made of two sheets joined at bond lines. | ¶34 | col. 4:6-14 |
| wherein the bond lines are elongated, wherein at least one end of each of the bond lines increases in width; | The complaint alleges the bond lines are "generally x-shaped and elongated," and that the ends increase in width to make a "flared, rounded end." This is supported by a photograph of an uninflated section of the pad. (Compl. ¶34). | ¶34 | col. 8:41-46 |
| a plurality of fluidly coupled cells defined between at least two bond lines of the plurality of bond lines... | The accused pad is alleged to include "many cells that are fluidly connected." This is supported by an image from the product's marketing materials showing the individual inflated cells. (Compl. ¶34). | ¶34 | col. 4:9-14 |
| and a first valve coupled to the frame and in fluid communication with the plurality of fluidly coupled cells. | The accused pad includes a valve that allows air into the fluidly coupled cells. The complaint provides a close-up photograph of the valve. (Compl. ¶34). | ¶34 | col. 4:1-4 |
- Identified Points of Contention:
- Scope Questions: The infringement allegation for both patents hinges on construing the accused product's "generally x-shaped" welds as meeting the claims' geometric limitations, such as a "rounded first end" and a "flared second end" (’955 Patent) or an "elongated" bond line where "at least one end... increases in width" (’814 Patent). A central dispute may be whether the "x-shape" is a single structure different from the claimed features.
- Technical Questions: The complaint's calculation of the "fill volume/pad area" ratio for the ’955 Patent is based on data from an Amazon listing and its own methodology for determining "pad area." (’955 Patent, col. 10:34-39; Compl. ¶23). The patent defines "pad area" as "the footprint of the pad when inflated," which may not be equivalent to the complaint's calculation using the surface area of the component material sheets. The accuracy of the underlying data and the validity of the calculation method present a potential factual dispute.
V. Key Claim Terms for Construction
The Term: "non-supporting regions" (from ’955 Patent, Claim 1)
Context and Importance: This term is fundamental to the patent's core concept of saving weight and volume. The definition will determine what portions of the accused pad must be assessed for this feature. Practitioners may focus on this term because a defendant could argue its entire pad is designed to be "supporting," thereby attempting to design around the claim.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim itself defines the term broadly as "non-inflating regions, the plurality of bond lines, and/or cutouts of the first and second sheets." (’955 Patent, col. 10:23-26). This language suggests the term can encompass a variety of structural features, not just areas with no inflation.
- Evidence for a Narrower Interpretation: The specification describes these regions functionally, stating they "typically have a vertical thickness less than half that of the supporting members" and are located in areas like the "middle back" or "upper leg region." (’955 Patent, col. 4:26-32, 5:35-41). This could support an argument that the term requires a specific structural and functional relationship to adjacent "supporting" regions.
The Term: "a rounded first end" and "a flared second end" (from ’955 Patent, Claim 1)
Context and Importance: The infringement reading depends on mapping these terms onto the "x-shaped" welds of the accused product. The construction of these geometric terms is therefore critical.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification explains the function of these shapes is to "distribute pull forces in a radial manner, which tends to minimize the chances of the first and second sheets pulling apart." (’955 Patent, col. 8:56-60). A party could argue that any weld termination shape that performs this function meets the claim's requirements.
- Evidence for a Narrower Interpretation: Figure 7 explicitly illustrates distinct "flares" (144a, 144b) and "rounded end[s]" (145), providing a specific embodiment. (’955 Patent, Fig. 7). A party could argue these figures limit the terms to the particular shapes depicted, which may differ from the defendant's "x-shaped" weld.
VI. Other Allegations
- Indirect Infringement: The complaint alleges that Defendants induce infringement of both patents by "knowingly encouraging or aiding others," including customers and partners, to use the accused sleeping pad in the United States. (Compl. ¶¶24, 35).
- Willful Infringement: For both patents, the complaint alleges deliberate and willful infringement. This allegation is supported by specific claims of pre-suit knowledge, citing dates of "no later than November 28, 2018" and "no later than December 11, 2018" on which Defendants and/or their attorney allegedly had actual knowledge of the infringement. (Compl. ¶¶27, 38).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the geometric terms "rounded first end" and "flared second end," as defined and described in the patents, be construed to read on the "generally x-shaped" welds of the accused product? The outcome of this claim construction battle will be pivotal for the infringement analysis of both patents.
- A key evidentiary question will be one of factual proof: will the plaintiff’s infringement theory for the "fill volume/pad area" ratio in the '955 Patent, which relies on calculations from marketing materials, withstand scrutiny? This will likely require expert testimony and a detailed factual analysis of the term "pad area" as defined in the patent versus the methodology used in the complaint.
