- Plaintiff’s Counsel: Hill, Kertscher & Wharton, LLP
- Case Identification: 1:23-cv-04716, N.D. Ga., 10/16/2023
- Venue Allegations: Plaintiff alleges venue is proper in the Northern District of Georgia because the Defendants' demand letter, which forms the basis of the dispute, was sent by a Georgia-based attorney from a Georgia address, constituting a substantial part of the events giving rise to the claims.
- Core Dispute: Plaintiff seeks a declaratory judgment that its "Presidio2" line of products does not infringe U.S. Patent No. 11,673,516 and that the patent's claims are invalid, in addition to alleging violations of Georgia's fair business practices statute.
- Technical Context: The lawsuit concerns protective cases for electronic devices, such as smartphones, a highly competitive and large-scale consumer products market.
- Key Procedural History: The action was precipitated by a demand letter sent on behalf of the Defendants on September 27, 2023, accusing Speck's products of infringement. The complaint raises a significant issue regarding the patent’s effective priority date, alleging that it is not entitled to the filing date of its parent application due to the addition of new matter, which could impact the validity analysis.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 11,673,516 - "Protective Frame," issued June 13, 2023
The Invention Explained
- Problem Addressed: The patent describes a trade-off in the design of protective cases: soft, flexible cases are easy to install but offer low-grade protection, while hard, rigid cases provide better protection but make it difficult to insert the device without compromising the case's structure ('516 Patent, col. 1:47-56).
- The Patented Solution: The invention is a protective case made from a "rigid" or "non-stretchable" material that incorporates one or more "slits" at or near the corners ('516 Patent, col. 1:25-29). As illustrated in Figure 1, these slits are designed to provide localized flexibility, allowing the rigid frame to flex just enough to enable the insertion of an electronic device, while maintaining overall structural integrity and protective qualities ('516 Patent, col. 3:34-40).
- Technical Importance: The technology aims to provide a protective case that combines the high-grade protection typical of hard-shell cases with the ease of installation characteristic of more flexible designs ('516 Patent, col. 1:56-60).
Key Claims at a Glance
- The complaint identifies independent claims 1 and 9 as being asserted against the Plaintiff (Compl. ¶7).
- Independent Claim 1 requires:
- A protective case with a base surface, at least one edge surface, at least one protruding lip, and at least one slit.
- The base, edge, and lip are made of a "rigid material."
- The slit is located at or near a corner and goes through the protruding lip and at least partially through the edge surface.
- The slit is configured to allow the protruding lip to "flex... enough to enable insertion of the electronic device."
- An edge of the protruding lip "features at least two curvatures," with "at least one of the at least two curvatures" securing "each of at least two opposite corners" of the device.
- The complaint notes that dependent claims 2 and 14 are also asserted (Compl. ¶5).
III. The Accused Instrumentality
Product Identification
- The complaint identifies the accused instrumentalities as Plaintiff's "Presidio2 product" line of protective cases for electronic devices (Compl. ¶5).
Functionality and Market Context
- The complaint describes the Presidio2 line as Plaintiff's "flagship smartphone case product line" (Compl. ¶27). The infringement allegations, as relayed in the complaint, are based on a demand letter that included annotated images of a "Presidio2 Grip Case" (Compl. ¶6; p. 4). One such image, a cross-section of the case, includes annotations from Defendants' counsel pointing to a "protruding lip" and a "softer surface" (Compl. p. 4). A second image shows another view of the cross-section with similar annotations (Compl. p. 4). The complaint argues that the "softer surface" highlighted in the patentee's own evidence is a feature not recited in the asserted claims (Compl. ¶7).
IV. Analysis of Infringement Allegations
The complaint seeks a declaratory judgment of non-infringement. The following table summarizes the key non-infringement argument presented in the complaint. The complaint focuses its argument on a single limitation, contending its failure renders the entire claim not infringed.
’516 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Non-Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a base surface, at least one edge surface, at least one protruding lip and at least one slit; | The complaint does not contest the existence of these general features but focuses its non-infringement argument on a subsequent limitation. | ¶14 | col. 8:22-24 |
| wherein the base surface, the at least one edge surface, and the at least one protruding lip are made of a rigid material; | The complaint notes that the Defendants' own infringement evidence points to a "softer surface," a term that does not appear in the claims, suggesting a potential mismatch with this limitation. | ¶7 | col. 8:36-39 |
| wherein the at least one slit is located at and/or near the respective corner of the protective case; | The complaint does not provide sufficient detail for analysis of this element. | --- | col. 8:40-43 |
| wherein an edge of the at least one protruding lip...features at least two curvatures, wherein at least one of the at least two curvatures secures each of at least two opposite corners of the at least four corners...respectively. | The complaint alleges that the protruding lips on the accused Presidio2 products do not have a single curvature that secures two separate corners, let alone two opposite corners of the case. | ¶14 | col. 8:46-52 |
Identified Points of Contention
- Scope Questions: The complaint's primary non-infringement argument centers on the interpretation of "at least one of the at least two curvatures secures each of at least two opposite corners." The dispute will question whether this language requires a single, continuous curve to physically engage two opposite corners, as the Plaintiff's argument suggests (Compl. ¶14).
- Technical Questions: A key factual question is whether the accused Presidio2 cases, which the Defendants' own evidence annotates as having a "softer surface," can be considered to be made of a "rigid material" as required by the claims (Compl. ¶7; '516 Patent, col. 8:36-39).
V. Key Claim Terms for Construction
- The Term: "secures each of at least two opposite corners"
- Context and Importance: This phrase is the foundation of the Plaintiff's express non-infringement argument (Compl. ¶14). Its construction is critical to determining whether the geometric configuration of the accused products' retaining lip meets the specific requirements of the claim.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A party could argue that the term does not require a single continuous curve to wrap around two corners, but rather that the overall lip structure, which contains curvatures, collectively secures the device at opposite corners.
- Evidence for a Narrower Interpretation: The Plaintiff's argument appears to rely on a plain reading that "at least one... curvature" must itself secure "each of at least two opposite corners" (Compl. ¶14). The absence of a specific embodiment or figure in the patent detailing this precise configuration may support an argument that the language should be interpreted narrowly based on its literal text.
- The Term: "rigid material"
- Context and Importance: Practitioners may focus on this term because the Defendants' demand letter allegedly identified a "softer surface" on the accused product (Compl. ¶7, p. 4), creating a potential mismatch with the claim's "rigid material" requirement.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent specification refers to materials that are "semi-rigid or non-stretchable," which could be argued to encompass a wider range of materials beyond those that are completely inflexible ('516 Patent, col. 3:25-27).
- Evidence for a Narrower Interpretation: The specification explicitly lists "carbon fiber, kelvar, metal, wood" as examples of "non-stretchable material," which could support a narrower construction requiring a high degree of stiffness ('516 Patent, col. 2:40-42).
VI. Other Allegations
- Violation of Georgia Fair Business Practices Act: The complaint includes a count alleging that the Defendants' demand letter constitutes a bad-faith assertion of patent infringement under Georgia law (Compl. ¶¶22-31). The basis for this claim includes allegations that the letter provided only "cursory factual analysis" (Compl. ¶6), asserted infringement against a product that allegedly predates the patent's effective filing date, and asserted claims that are "meritless" based on a plain reading (Compl. ¶25, 29).
VII. Analyst’s Conclusion: Key Questions for the Case
- A central issue for the invalidity claim will be one of effective priority: is the '516 patent entitled to its 2019 parent application's priority date, or did the introduction of new matter, as the complaint alleges, reset its effective filing date to June 2020? The answer will determine whether the accused Presidio2 product, allegedly sold since May 2020, qualifies as invalidating prior art.
- The non-infringement case will likely turn on a question of definitional scope: how will the court construe the phrase "at least one of the at least two curvatures secures each of at least two opposite corners"? The resolution of this ambiguous language will be a critical determinant of infringement.
- A key evidentiary question will be one of factual characterization: do the materials used to construct the accused Presidio2 products meet the "rigid material" limitation as required by the claims, particularly in light of the Defendants' own evidence allegedly pointing to a "softer surface"?
