II. Technology and Patent(s)-in-Suit Analysis
U.S. Design Patent No. D705,339, "Eyeglass," Issued May 20, 2014
The Invention Explained
- Problem Addressed: The patent addresses the need for a new, original, and ornamental design for an eyeglass frame, distinct from prior art designs in a competitive market (D’339 Patent, Claim, Figs. 1-6).
- The Patented Solution: The patent discloses a specific ornamental design for an eyeglass frame characterized by a semi-rimless construction with a distinct upper frame profile and uniquely shaped earstems (D’339 Patent, Figs. 1-6). The drawings show the lenses in broken lines, indicating that the claimed design applies to the frame only, and not the shape of the lenses themselves (D’339 Patent, Description, col. 2:13-15).
- Technical Importance: In the eyewear industry, novel frame aesthetics serve to create distinct product identities and brand recognition (Compl. ¶7).
Key Claims at a Glance
- The single asserted claim is for "The ornamental design for an eyeglass, as shown and described" (D’339 Patent, Claim).
- The scope of this claim is defined by the solid lines in the patent figures, which depict the following key ornamental features:
- A continuous upper frame member extending into integrated earstems.
- A semi-rimless design where the bottom of the lenses are exposed.
- A specific contoured shape for the earstems.
U.S. Design Patent No. D652,442, "Eyeglass," Issued January 17, 2012
The Invention Explained
- Problem Addressed: This patent addresses the need for a new, original, and ornamental design for a full-frame eyeglass (D’442 Patent, Claim, Figs. 1-6).
- The Patented Solution: The patent protects the specific visual appearance of a full-frame eyeglass, where both the frame and the lenses are shown in solid lines, making them part of the claimed design (D’442 Patent, Figs. 1-6). Key features include the specific rectangular lens shape, the contours of the full frame surrounding the lenses, and the shape of the associated earstems (D’442 Patent, Figs. 1, 2, 4).
- Technical Importance: The creation of a holistic design encompassing both frame and lens shape provides a distinct and recognizable product appearance in the market (Compl. ¶7).
Key Claims at a Glance
- The single asserted claim is for "The ornamental design for an eyeglass, as shown and described" (D’442 Patent, Claim).
- The scope of this claim is defined by the solid lines in the patent figures, encompassing the combination of:
- A full-frame structure.
- A specific, generally rectangular lens shape.
- The particular contour and thickness of the frame members and earstems.
III. The Accused Instrumentality
Product Identification
- The complaint identifies two accused products: the "Polarized Sport Rim Sunglasses" and the "Short Stop Sunglasses" (Compl. ¶¶ 25, 27).
Functionality and Market Context
- The "Polarized Sport Rim Sunglasses" are alleged to be a "nearly identical copy" of the design claimed in the ’339 Patent (Compl. ¶26). A visual provided in the complaint shows a side-by-side comparison of the accused product and a figure from the ’339 Patent (Compl. p. 7).
- The "Short Stop Sunglasses" are alleged to be a "nearly identical copy" of the design claimed in the ’442 Patent (Compl. ¶28). The complaint provides a comparative image showing the accused "Short Stop" product next to a drawing from the ’442 Patent (Compl. p. 8).
- The complaint alleges that Defendant’s actions are inconsistent with the standards of commerce for the eyewear industry (Compl. ¶¶ 26, 28).
IV. Analysis of Infringement Allegations
The standard for design patent infringement is whether an "ordinary observer," familiar with the prior art, would be deceived into purchasing the accused product believing it to be the patented design.
D705,339 Infringement Allegations
| Ornamental Feature (from the claim as depicted in the figures) | Alleged Infringing Functionality (of the "Polarized Sport Rim Sunglasses") | Complaint Citation | Patent Citation |
|---|---|---|---|
| The overall ornamental appearance of the eyeglass frame, including its semi-rimless configuration and earstem shape. | Defendant's "Polarized Sport Rim Sunglasses" model is alleged to have a design that would appear to an ordinary observer to be substantially similar to the claim of the D339 Patent. | ¶25 | Figs. 1-6 |
| A continuous upper frame member that flows into the earstems. | The accused product features a continuous upper frame member. | p. 7 | Fig. 1 |
| A semi-rimless design where the lower portion of the lens is not enclosed by a frame. | The accused product is a semi-rimless design. | p. 7 | Fig. 1 |
| The specific contour and curvature of the earstems. | The earstems of the accused product are alleged to have a substantially similar shape and contour. | p. 7 | Fig. 4 |
D652,442 Infringement Allegations
| Ornamental Feature (from the claim as depicted in the figures) | Alleged Infringing Functionality (of the "Short Stop Sunglasses") | Complaint Citation | Patent Citation |
|---|---|---|---|

| The shape and profile of the frame and earstems. | The frame and earstems of the accused product are alleged to have a substantially similar profile and contours. | p. 8 | Fig. 4 |
Identified Points of Contention
- Scope Questions: A central question for the ’339 Patent will be the impact of the broken lines used for the lenses. The claim is to the frame design only. The analysis may focus on whether an ordinary observer's comparison properly isolates the claimed frame from the unclaimed lenses, or if the overall impression is what matters. For the ’442 Patent, since the lenses are claimed, the analysis will be on the overall combined appearance.
- Technical Questions: The infringement analysis will turn on a visual comparison. The court will need to assess whether the specific differences in curvature, proportion, and surface detailing between the patented designs and the accused products are significant enough to be noticed by an ordinary observer, or if they are minor differences that do not prevent the overall appearances from being substantially similar. The complaint's visual evidence, which shows the accused product next to a patent line drawing, will be a focal point of this analysis (Compl. p. 7-8).
V. Key Claim Terms for Construction
In design patent cases, "claim construction" involves determining the scope and meaning of the design as depicted in the patent's figures. The primary issue is defining the overall ornamental appearance protected by the patent.
- The Term: "ornamental design for an eyeglass, as shown" (D’339 Patent, Claim; D’442 Patent, Claim).
- Context and Importance: The construction of this phrase defines the entire scope of protection. Practitioners may focus on which specific visual elements are part of the "as shown" design and the level of detail required for a finding of substantial similarity.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A party seeking a broader scope might argue that the claim covers the overall visual impression and general configuration of the design, and that minor differences in proportion or surface detail do not escape infringement (D’339 Patent, Fig. 1; D’442 Patent, Fig. 1).
- Evidence for a Narrower Interpretation: A party seeking a narrower scope would argue that the claim is limited to the precise shapes and contours shown in the figures (D’339 Patent, Figs. 2, 4, 5; D’442 Patent, Figs. 2, 4, 5). For the ’339 Patent specifically, a narrower interpretation would emphasize that the lenses are shown in broken lines, explicitly disclaiming their shape from the scope of the patent's claim and limiting the comparison to the frame alone (D’339 Patent, Description, col. 2:13-15).
VI. Other Allegations
- Indirect Infringement: The complaint does not contain specific allegations of induced or contributory infringement.
- Willful Infringement: The complaint alleges willful infringement based on Defendant's alleged actual knowledge of the asserted patents since at least January 22, 2016 (Compl. ¶¶ 13, 26, 28). It further alleges that Defendant's actions were undertaken with "reckless disregard" of Oakley's patent rights and were not consistent with industry standards (Compl. ¶¶ 26, 28).
VII. Analyst’s Conclusion: Key Questions for the Case
- A central issue will be the application of the "ordinary observer" test: Will the finder of fact, when comparing the accused products to the patented designs, conclude that the designs are substantially the same such that an ordinary observer would be deceived? This will involve a detailed visual comparison of the products' overall configurations and specific ornamental features.
- A key question of claim scope will arise for the ’339 Patent: How will the court treat the unclaimed lens portions (shown in broken lines) during the infringement analysis? The case may turn on whether the comparison is properly limited to the claimed frame elements or if the overall product gestalt, including the lenses, influences the ordinary observer's perception.
- An important evidentiary question will be the impact of the alleged pre-suit notice: If infringement is found, the allegation that Defendant had knowledge of the patents for nearly two years before the suit was filed will be central to Plaintiff's claim for enhanced damages due to willful infringement.
