II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,527,241 - "Apparatus for Cooling a Laptop Computer"
- Patent Identification: U.S. Patent No. 6,527,241, "Apparatus for Cooling a Laptop Computer," issued March 4, 2003.
The Invention Explained
- Problem Addressed: The patent identifies two problems with contemporary laptops: 1) new designs using heat-retentive materials like metal alloys cause the devices to become uncomfortably hot, and 2) the gradual elimination of built-in adjustable legs, done to save space, prevents users from positioning the keyboard at a comfortable, ergonomic angle ('241 Patent, col. 1:20-45).
- The Patented Solution: The invention is a stand for a laptop computer that elevates and angles the device. It consists of a single "concave member" with a rear portion that is higher than its front portion ('241 Patent, Abstract). This structure simultaneously cantilevers the laptop off a surface to create an air channel for improved cooling and tilts the keyboard forward to reduce physical strain for the user ('241 Patent, col. 1:58-68). Figure 3 illustrates how the concave shape of the stand (40) creates an air channel (34) beneath the laptop (32) ('241 Patent, Fig. 3).
- Technical Importance: The invention provides a single, simple apparatus to solve the dual problems of laptop overheating and poor ergonomics, which the patent asserts improves both the usable life of the computer and the comfort of the user ('241 Patent, col. 1:60-68).
Key Claims at a Glance
- The complaint asserts independent claim 1 and dependent claim 6 ('241 Patent, Compl. ¶¶10-11).
- Independent Claim 1 requires:
- A member having a first portion and a second portion, said first portion having a first height, said second portion having a second height which is substantially higher than said first height
- The member is adapted to receive a laptop computer to both angle and space the laptop above a surface to facilitate cooling
- The member is concave and opens upward to create space below the supported laptop computer
- The complaint does not explicitly reserve the right to assert other claims.
III. The Accused Instrumentality
Product Identification
The "Comforter (C-HS02-KA)" is identified as the Accused Product (Compl. ¶9).
Functionality and Market Context
- The complaint describes the Accused Product as a "laptop stand" that incorporates "cooling features" (Compl. ¶9).
- A visual provided in the complaint depicts the Accused Product as a cushioned lap desk designed to hold a laptop computer (Compl. p. 5). This image shows the product has a non-uniform thickness, creating an angled surface for the laptop placed upon it, and is used to support the computer on a user's lap or other surface (Compl. p. 5). The complaint does not provide further detail on the product's specific materials or market position.
IV. Analysis of Infringement Allegations
’241 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a member having a first portion and a second portion, said first portion having a first height, said second portion having a second height which is substantially higher than said first height | The accused lap desk is a "member" with a "First Portion" and a "Second Portion," where the second portion is visually depicted as being thicker and thus higher than the first. | ¶10; p. 5 | col. 2:53-58 |
| wherein said member is adapted to receive a laptop computer so as to both angle and space said laptop above a surface to facilitate the cooling thereof | The accused lap desk is shown holding a laptop at an angle, which spaces the laptop from the underlying surface (e.g., a user's lap) to permit cooling. | ¶10; p. 5 | col. 1:46-50 |
| wherein said member is concave and opening upward to create space below the supported laptop computer | The accused lap desk is described as "concave and opening upward," and a provided visual shows that its shape creates space between the bottom of the laptop and the main body of the stand. | ¶10; p. 5 | col. 3:35-39 |
Identified Points of Contention
- Scope Questions: The patent specification repeatedly describes the invention as an "integral member made of molded plastic" ('241 Patent, col. 2:53-54) and having a specific "X-shaped" geometry in its preferred embodiment ('241 Patent, col. 3:12-14). The accused "Comforter" product appears to be a cushioned, soft-surfaced lap desk (Compl. p. 5). A central dispute may be whether the term "member" as used in the claims can be construed to read on a soft, cushioned article, or if its meaning is limited by the specification to the rigid, molded structures disclosed.
- Technical Questions: Claim 1 requires the member to be "concave." The complaint's visual of the accused product shows an angled, cushioned surface (Compl. p. 5). The infringement analysis may turn on whether this cushioned shape meets the claimed "concave" limitation, which the patent links to the function of forming an "air channel 34" ('241 Patent, col. 3:35-39). The evidentiary question will be whether the accused product's structure is technically equivalent to the claimed "concave" structure for the purpose of creating this cooling space.
V. Key Claim Terms for Construction
The Term: "concave"
- Context and Importance: This term is critical because it defines the shape of the member responsible for creating the cooling space. The dispute will likely focus on whether "concave" requires a specific, rigid, geometric curve as shown in the patent's figures, or if it can broadly describe any shape that results in a hollow space beneath the laptop, such as the cushioned surface of the accused product. Practitioners may focus on this term because the visual evidence for the accused product suggests a soft, pliable form rather than a fixed geometric one (Compl. p. 5).
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim language itself does not specify a material or degree of curvature, simply requiring a member that is "concave and opening upward to create space" ('241 Patent, col. 4:17-19). The summary of the invention states the goal is to "space a laptop computer above a surface to facilitate the cooling thereof" ('241 Patent, col. 1:58-60), a function that a cushioned, angled shape could perform.
- Evidence for a Narrower Interpretation: The detailed description links the term directly to a specific structure: "air channel 34 is formed between a concave surface 40 of member 12 and laptop 32" ('241 Patent, col. 3:35-37). The figures depict a distinct, smooth, and rigid-looking curve (e.g., '241 Patent, Fig. 1, Fig. 3), which could support an argument that "concave" implies more than just creating space, but creating it in a specific, structurally-defined way.
The Term: "member"
- Context and Importance: The definition of "member" will determine if the claim is limited to a single, unitary object or can cover composite or soft-goods articles. The infringement read depends on the accused cushioned lap desk qualifying as a "member."
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: Independent claim 1 broadly recites "a member" without further limitation as to its material or construction ('241 Patent, col. 4:9).
- Evidence for a Narrower Interpretation: The preferred embodiment is consistently described as an "integral member 12 made of molded plastic" ('241 Patent, col. 2:53-54). Dependent claim 6, which is also asserted, explicitly adds the limitation "wherein said member is an integral member made of molded plastic" ('241 Patent, col. 4:28-29). A defendant may argue this suggests the patentee viewed "member" in the context of a single, molded piece of plastic.
VI. Other Allegations
- Indirect Infringement: The complaint does not allege facts sufficient to support a claim for indirect infringement.
- Willful Infringement: The complaint does not allege facts sufficient to support a claim for willful infringement.
VII. Analyst’s Conclusion: Key Questions for the Case
This case appears to center on fundamental questions of claim scope and construction. The key issues for the court will likely be:
A core issue will be one of definitional scope: can the term "member", as used in the claims and described in a preferred embodiment as a "molded plastic" structure, be construed to cover the soft-surfaced, cushioned lap desk that constitutes the accused product?
A related evidentiary question will be one of technical interpretation: does the accused product’s angled, cushioned surface meet the claim limitation of being "concave" in the manner taught by the patent, which links the shape to the formation of a specific "air channel" for cooling?
