Danik Industries Ltd v. Xander Bicycle Corp
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Danik Industries, Ltd. (Canada)
- Defendant: Xander Bicycle Corp (California); Ningbo EZ Machinery Co. Ltd. (China)
- Plaintiff’s Counsel: Rutan & Tucker, LLP
- Case Identification: 2:18-cv-09079, C.D. Cal., 10/22/2018
- Venue Allegations: Venue is alleged to be proper in the Central District of California because Defendant Xander Bicycle Corp is incorporated in California, has its principal place of business in the district, and has a regular and established place of business in the district from which it has allegedly committed acts of infringement.
- Core Dispute: Plaintiff alleges that Defendants’ bicycle rack infringes a patent related to an adaptable drawbar assembly that can fit different sizes of trailer hitch receivers.
- Technical Context: The technology addresses the need for vehicle accessories, such as bicycle racks, to be compatible with the different standardized sizes of trailer hitch receivers found on automobiles.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,717,455 - Adaptable Trailer Drawbar Assembly
- Patent Details: Issued May 18, 2010 (’455 Patent)
The Invention Explained
- Problem Addressed: The patent's background section describes the problem that vehicle accessories designed to mount into trailer hitch receivers must be built for specific receiver sizes (e.g., 1.25-inch Class I vs. 2-inch Class III) (’455 Patent, col. 1:28-38). This forces manufacturers to maintain a larger inventory of different models and can require consumers to purchase cumbersome adapters or new accessories if they change vehicles (’455 Patent, col. 1:33-41).
- The Patented Solution: The invention is a drawbar assembly featuring a central shank sized to fit a smaller hitch receiver. Two L-shaped adapter parts can be removably attached to opposite sides of the shank, increasing its outer dimensions to fit a larger hitch receiver (’455 Patent, Abstract; col. 2:42-58). This allows a single accessory to be adapted for use with at least two different standard receiver sizes (’455 Patent, col. 2:59-67).
- Technical Importance: This design offers an integrated method for adapting an accessory to multiple hitch sizes, potentially reducing manufacturing costs and increasing convenience for the end-user.
Key Claims at a Glance
- The complaint asserts independent claim 1 and dependent claims 2 and 3 (Compl. ¶14).
- Independent Claim 1 requires:
- a shank;
- a first adapter part having two sides forming a right angle, the first adapter part removably coupled to the shank;
- a second adapter part having two sides forming a right angle, the second adapter part removably coupled to the shank opposite the first adapter part.
III. The Accused Instrumentality
Product Identification
- The "Critical Cycles Lenox Hitch Mount Tray Rack 2 Bike" (the "Accused Rack") (Compl. ¶11, ¶13).
Functionality and Market Context
- The Accused Rack is a bicycle carrier designed to be mounted to a vehicle's trailer hitch receiver (Compl. ¶13). The complaint alleges Defendant Xander sells the Accused Rack on www.amazon.com and that Defendant Ningbo is the manufacturer, selling it to resellers like Xander and directly to consumers through www.alibaba.com (Compl. ¶11, ¶15). The complaint includes a photograph of the Accused Rack, showing a hitch-mounted bicycle carrier with two trays for holding bicycles. (Compl. ¶13, p. 4).
IV. Analysis of Infringement Allegations
The complaint alleges that the Accused Rack "meets every element of at least claims 1, 2 and 3 of the '455 Patent" but does not provide a detailed, element-by-element breakdown of its infringement theory (Compl. ¶14). The analysis below is based on the complaint's general allegations.
’455 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a shank; | The complaint alleges the Accused Rack includes a shank for insertion into a vehicle hitch receiver. | ¶14 | col. 2:30-35 |
| a first adapter part having two sides forming a right angle, the first adapter part removably coupled to the shank; | The complaint alleges the Accused Rack includes a first adapter part with the claimed geometry that is removably coupled to the shank. | ¶14 | col. 2:42-51 |
| a second adapter part having two sides forming a right angle, the second adapter part removably coupled to the shank opposite the first adapter part. | The complaint alleges the Accused Rack includes a second, opposing adapter part with the claimed geometry that is removably coupled to the shank. | ¶14 | col. 2:46-51 |
Identified Points of Contention
- Technical Questions: A primary factual question will be whether the Accused Rack, as depicted in the complaint's photograph (Compl. ¶13, p. 4), actually incorporates the claimed structure of a central shank with two separate, L-shaped, and removably coupled adapter parts. The complaint does not provide specific evidence or description of the Accused Rack's adaptability mechanism.
- Scope Questions: The dispute may turn on the construction of key claim terms. The evidence presented will need to show that the components of the Accused Rack correspond to the specific structural limitations of the claims, such as the "two sides forming a right angle" geometry for the adapter parts.
V. Key Claim Terms for Construction
The Term
- "removably coupled"
Context and Importance
- This term is critical to the invention's core concept of adaptability. The infringement analysis will depend on whether the mechanism used in the Accused Rack to adjust its size, if any, falls within the scope of "removably coupled" as understood from the patent. Practitioners may focus on this term because the patent discloses a specific coupling method (a threaded fastener) which may influence the term's construction.
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: The claim language itself does not specify the mechanism of coupling, suggesting any form of removable attachment could be covered. The summary section broadly describes the parts as "removably coupled to the shank on opposite sides" without limiting the method (’455 Patent, col. 2:48-50).
- Evidence for a Narrower Interpretation: The specification’s preferred embodiment describes and depicts the adapter parts being coupled by a "threaded fastener" that passes through the shank and secures the two parts together (’455 Patent, col. 3:3-7; Fig. 2). A defendant might argue this embodiment limits the scope of "removably coupled" to a specific type of mechanical fastening.
VI. Other Allegations
Indirect Infringement
- The complaint does not contain a separate count for indirect infringement. It alleges Defendant Ningbo manufactures the Accused Rack and sells it to resellers like Xander, and that both entities sell, offer to sell, or import the product in the United States (Compl. ¶14, ¶15). These allegations are framed as acts of direct infringement.
Willful Infringement
- The complaint alleges that Defendants' infringement "has been and will continue to be willful, wanton and deliberate" (Compl. ¶17). This allegation is based on the claim that Plaintiff provided Defendant Xander with actual knowledge of the ’455 Patent and the alleged infringement via a letter dated July 13, 2018 (Compl. ¶11).
VII. Analyst’s Conclusion: Key Questions for the Case
A central factual question will be one of structural correspondence: Does the "Critical Cycles Lenox Hitch Mount Tray Rack 2 Bike" actually possess the physical structure recited in Claim 1—specifically, a central shank and two distinct, right-angled adapter parts that are "removably coupled" to it? The complaint's conclusory allegations will require evidentiary support to substantiate this claim.
The case may also turn on a question of claim scope: What is the proper construction of "removably coupled"? The court will need to determine if this term is limited to the screw-based mechanism shown in the patent's embodiments or if it covers any method of making the drawbar adaptable to different receiver sizes.
A third key issue involves liability and jurisdiction: Can the plaintiff establish personal jurisdiction over the foreign manufacturer, Ningbo EZ Machinery Co. Ltd., based on its alleged sales to U.S. consumers through online platforms? The resolution of this question will determine whether liability extends beyond the U.S.-based distributor, Xander.
