Luv N' Care Ltd v. Toys R US Inc
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Luv N' Care, Ltd. (Louisiana) and Admar International, Inc. (Delaware)
- Defendant: Toys "R" Us, Inc. (Delaware) and Munchkin, Inc. (California)
- Plaintiff’s Counsel: Goldberg Cohen LLP
- Case Identification: 1:12-cv-00228, S.D.N.Y., 01/11/2012
- Venue Allegations: Venue is alleged based on Defendants directing tortious activities toward New York, delivering infringing products into the state for sale, and Defendant Toys "R" Us operating retail stores within the judicial district.
- Core Dispute: Plaintiffs allege that children's drinking cups sold by Defendants under brands including Tommee Tippee and Munchkin infringe the ornamental designs claimed in two U.S. design patents.
- Technical Context: The dispute is in the highly competitive consumer market for juvenile products, specifically "sippy cups," where distinctive ornamental design can be a significant market differentiator.
- Key Procedural History: The complaint references prior litigation involving Plaintiffs and third parties related to similar product designs, including a settlement agreement with Royal King Infant Product Co., Ltd. Notably, subsequent to the filing of this complaint, both patents-in-suit had their claims cancelled. The claim of the D617,465 patent was cancelled following an Inter Partes Review (IPR) initiated by the Defendants in this case, and the sole claim of the D634,439 patent was cancelled following an Inter Partes Reexamination. These cancellations are dispositive of the patent infringement claims.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Design Patent No. D617,465 - "Drinking Cup," Issued June 8, 2010
The Invention Explained
- Problem Addressed: Design patents protect ornamental appearance, not utility. As such, the patent does not articulate a technical problem but instead presents a novel visual design for a consumer product (D'465 Patent, Description).
- The Patented Solution: The patent claims the ornamental design for a drinking cup as depicted in its figures (D'465 Patent, Claim, Figs. 1-5). The core visual features include an hourglass-like body with a pronounced, inwardly curved grip section separating a larger upper portion from a smaller base. The overall aesthetic is a combination of these contours and proportions.
- Technical Importance: In the market for children's products, unique and aesthetically pleasing designs can serve as a key source identifier and driver of consumer purchasing decisions (Compl. ¶¶ 26, 30).
Key Claims at a Glance
- Design patents contain a single claim, which is directed to the ornamental design as a whole, as shown in the patent's drawings. The asserted claim is:
- The ornamental design for a drinking cup, as shown and described.
U.S. Design Patent No. D634,439 - "Drinking Cup Top," Issued March 15, 2011
The Invention Explained
- Problem Addressed: Similar to the '465 patent, the '439 patent does not describe a technical problem but instead claims rights to a specific ornamental design (D'439 Patent, Description).
- The Patented Solution: The patent claims the ornamental design for a drinking cup top, as illustrated in the figures (D'439 Patent, Claim, Figs. 1-6). The design is characterized by a specific combination of features, including a soft, oval-shaped spout, its placement relative to a smaller circular vent opening on the top surface, and the overall convex and layered profile of the top assembly. The broken lines in the figures indicate that the cup body itself is not part of the claimed design ('439 Patent, Description).
- Technical Importance: The design of a "sippy cup" top, particularly the spout, is a primary point of interaction for the user (a child) and a focal point for the purchaser, making its ornamental design a commercially significant feature (Compl. ¶¶ 14, 32).
Key Claims at a Glance
- The patent asserts a single claim for the ornamental design as illustrated:
- The ornamental design for a drinking cup top, as shown and described.
III. The Accused Instrumentality
Product Identification
- The complaint accuses drinking cups sold by Defendant Toys "R" Us under the TOMMEE TIPPEE, EXPLORA, WAGI, and MUNCHKIN brand names (Compl. ¶19). The products are allegedly manufactured or supplied by Defendant Munchkin, as well as non-parties Mayborn, Jackel, and Royal King (Compl. ¶20).
Functionality and Market Context
- The accused instrumentalities are children's "sippy cups" intended for toddlers. The complaint focuses entirely on their ornamental appearance, alleging they are "deceptive and confusing knock-offs" of Plaintiffs' "Gripper Cup" and "Grip n' sip" products, which allegedly embody the patented designs (Compl. ¶¶ 45-46, 55-56). The complaint provides visual evidence in its exhibits, such as a side-by-side comparison of Plaintiffs' "Gripper Cup" and an accused Munchkin product. (Compl. ¶47; Exhibit 11). Another exhibit presents a three-panel comparison of Plaintiffs' "Grip n' sip" product with accused cups from Mayborn and Munchkin (Compl. ¶¶ 54-58; Exhibit 14). These exhibits are presented to support the allegation that the accused products were designed to resemble Plaintiffs' products (Compl. ¶63).
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. The complaint alleges infringement by presenting side-by-side photographic comparisons.
D'465 Patent Infringement Allegations
| Claim Element (from Claim 1 as shown in figures) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| The overall hourglass-like contoured body shape. | The accused products are alleged to be "copies" featuring a visually similar contoured shape. | ¶¶ 44, 49 | Fig. 1 |
| A distinct, inwardly curved grip section dividing the upper and lower body. | The accused Munchkin cup depicted in Exhibit 11 features a recessed grip section in a similar location to the patented design. | ¶49 | Fig. 2 |
| The specific proportional relationship between the upper body, grip section, and base. | The accused products are alleged to be "knock-offs" that mimic the overall proportions of the patented design, creating a confusingly similar appearance. | ¶¶ 46, 52 | Fig. 1 |
D'439 Patent Infringement Allegations
| Claim Element (from Claim 1 as shown in figures) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| The ornamental design for the drinking cup top as a whole. | The tops of the accused cups sold under the Munchkin and Tommee Tippee brands are alleged to be copies of the patented design. | ¶¶ 19, 20 | Fig. 6 |
| An oval-shaped, soft-style spout. | The complaint alleges infringement by products that include a visually similar spout design, as depicted in the exhibits. | ¶19; Exhibit 14 | Fig. 3 |
| A convex top surface with a specific spatial arrangement of the spout and a smaller circular vent opening. | The exhibits show accused cup tops that feature spouts and vents in an arrangement alleged to be confusingly similar to the patented design. | ¶43; Exhibit 14 | Fig. 3 |
- Identified Points of Contention:
- Scope Questions: The central question in a design patent case is the scope of the claimed design in light of the prior art. The analysis would have centered on whether the similarities between the accused products and the patented designs pertain to novel ornamental features or to features already common in the prior art for sippy cups.
- Technical Questions: The dispute is not technical but aesthetic. The key question for the fact-finder would have been whether the overall visual impression of the accused cups is "substantially the same" as the patented designs, or if the visual differences are significant enough to avoid deceiving an ordinary observer.
V. Key Claim Terms for Construction
In design patent litigation, claim construction focuses on the overall visual impression of the design as shown in the drawings, rather than the construction of specific text. The "claim" is understood to be the design itself.
- The Term: "Drinking Cup" ('465 Patent) and "Drinking Cup Top" ('439 Patent).
- Context and Importance: The title of a design patent defines the article of manufacture to which the design is applied. This sets the stage for the infringement analysis by identifying the relevant market and class of products for comparison. Practitioners may focus on this to ensure the accused product is an article of the same type as that identified in the patent.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The terms themselves are general. One might argue they cover a wide range of beverage containers for drinking.
- Evidence for a Narrower Interpretation: The figures in both patents clearly depict a specific type of container: a child's "sippy cup" (D'465 Patent, Fig. 1; D'439 Patent, Fig. 1). The complaint itself refers to the invention as relating to "children's sippy cups" (Compl. ¶14). This context would likely confine the scope of the terms to this specific sub-category of drinking cups.
VI. Other Allegations
- Indirect Infringement: The complaint does not contain a separate count for indirect patent infringement. However, the prayer for relief seeks to enjoin "contributorily infring[ing] or actively induc[ing] infringement" (Compl. Prayer for Relief ¶E). The factual allegations state that Defendant TRU sells infringing cups obtained from manufacturers like Defendant Munchkin, which could support such a claim (Compl. ¶¶ 13, 20).
- Willful Infringement: The complaint alleges that Defendants' infringement was "willful and deliberate" (Compl. ¶90). This allegation is supported by claims that Defendants had knowledge of the Design Patents, that Defendant TRU previously sold Plaintiffs' own products and was aware of their popularity, and that TRU was aware of related litigation and settlements involving Plaintiffs' designs (Compl. ¶¶ 65, 75-78, 89).
VII. Analyst’s Conclusion: Key Questions for the Case
While the subsequent cancellation of all asserted patent claims in post-grant proceedings effectively terminated this patent dispute, the central questions raised by the complaint at the time of its filing highlight classic issues in design patent litigation.
- Validity Over Prior Art: The primary unresolved issue was whether the specific ornamental designs of the '465 and '439 patents were nonobvious and novel when compared to the field of prior art for children's drinking cups. The later cancellation of the claims in IPR and reexamination proceedings answered this question in the negative.
- Scope of Protection & Infringement: A key question for the court would have been to determine the scope of the design protection in light of the prior art and then to assess, from the perspective of an ordinary observer, whether the overall visual appearance of the accused Munchkin and Tommee Tippee cups was "substantially the same" as the claimed designs. This involves comparing the designs as a whole, not just individual features.
