II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 9,938,677 - Impact – Resistant and Energy-Absorbing Item of Street Furniture

The Invention Explained

  • Problem Addressed: Conventional rigid street furniture, like bollards, can cause significant damage to both the furniture and the impacting vehicle or person. Prior art energy-absorbing designs often rely on a simple tipping or pivoting motion, which may be less effective for impacts occurring very low to the ground. ('677 Patent, col. 1:13-22, col. 2:41-58).
  • The Patented Solution: The invention describes a three-part assembly (post, base plate, and an energy-absorbing element) designed to produce a more complex motion upon a low impact. Instead of just tipping, the post undergoes an "obliquely, downwardly directed sliding movement" relative to the base plate. This combined horizontal and vertical motion is damped by an internal energy-absorbing element, which is pre-loaded to keep the post upright in its normal state. ('677 Patent, Abstract; col. 3:35-49). Figure 4 illustrates the post after impact, having moved both sideways and downwards into the base. ('677 Patent, Fig. 4).
  • Technical Importance: This approach seeks to improve energy dissipation by engaging the absorbing element through both vertical compression and horizontal displacement, providing a more robust response to low-height impacts that might otherwise create a simple, high-stress pivot point. ('677 Patent, col. 3:45-56).

Key Claims at a Glance

  • The complaint asserts infringement of at least independent Claim 1. (Compl. ¶20).
  • The essential elements of Claim 1 include:
    • An item of street furniture comprising a post, a base plate with a flange/collar, and an energy-absorbing element.
    • Only the base plate is secured to a ground surface, and it defines a hollow space with the post and the ground.
    • The energy-absorbing element is located in the hollow space and is arranged to press the post and base plate together, creating a "first direct contact."
    • The arrangement allows the element to absorb an initial movement, after which the post contacts an inner edge of the base plate's flange, creating a "second direct contact" that forms a "rigid whole" and prevents further loading of the absorbing element.
    • The post and base plate are shaped such that a low impact load results in an "obliquely, downwardly directed sliding movement" of the post, which is damped by the energy-absorbing element.
  • The complaint does not explicitly reserve the right to assert dependent claims, but the allegation of infringement of "one or more claims" is a general reservation. (Compl. ¶24).

III. The Accused Instrumentality

Product Identification

The "Global Industrial™ Rebounding Safety Bollard, 4” Diameter by Forty-two inches Height” (Model #WQ670782) (the "Accused Product"). (Compl. ¶18).

Functionality and Market Context

The Accused Product is a safety bollard designed to be anchored to a floor or ground surface. (Compl. ¶¶ 18, p. 7). An exploded diagram provided in the complaint shows it is comprised of a base, a post, a "Rubber Pad," and a "Sleeve," among other components. (Compl. p. 6). The complaint alleges that the "Rubber Pad" and/or "Sleeve" function as an energy-absorbing element situated inside the base. (Compl. p. 6). Defendant's marketing materials state the product's "base features a rubber interior to help with rebounding absorption." (Compl. p. 7). The product is marketed for industrial and safety applications to protect assets from impacts. (Compl. p. 6).

IV. Analysis of Infringement Allegations

Claim Chart Summary

The complaint provides allegations mapping features of the Accused Product to the elements of Claim 1 of the ’677 Patent. (Compl. ¶20). The complaint includes an exploded diagram of the Accused Product showing its components. (Compl. p. 6). A photograph of the assembled base is also provided, captioned "Base Plate Allows Floor Anchoring For Additional Stability". (Compl. p. 7).

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
An item of street furniture comprising three parts, said parts being a post, a base plate having a flange or collar and an energy-absorbing element The Accused Product is comprised of a post (Ref #3), a base (Ref #5), and an energy-absorbing element (Ref #8 "Rubber Pad" and/or Ref #6 "Sleeve"). ¶20, p. 6 col. 5:15-18
wherein only the base plate is secured directly to an existing ground surface...and is provided with a hollow space formed by the post, an inner wall of the base plate and the ground surface... A photo shows the base plate is secured directly to the ground for "Floor Anchoring." The diagram and physical examination allegedly show a hollow space is formed by the post, the inner wall of the base, and the ground. ¶20, p. 7-8 col. 3:3-6; col. 5:28-34
wherein the energy-absorbing element is located within the hollow space and is arranged...that the energy-absorbing element presses the post and the base plate together at all times, thereby creating a first direct contact Based on the product diagram and physical examination, the "Rubber Pad" is located in the hollow space and arranged to press the post and base plate together at all times. ¶20, p. 8 col. 7:5-15
After a relative movement...the post comes into contact with an inner edge of the flange or collar of the base plate...a second direct contact is established...a rigid whole is formed...the energy-absorbing element is not additionally loaded Based on physical examination, after a relative movement, the post contacts an inner edge of the base plate's flange, creating a second direct contact and forming a rigid whole, which stops further loading of the energy-absorbing element. ¶20, p. 9 col. 8:22-40
wherein the post and the base plate are shaped [so that] when the post is loaded just above the base plate, an obliquely, downwardly directed sliding movement of the post relative to the base plate is obtained, which is damped by the energy absorbing element. Based on physical examination, the post and base are shaped such that a low load results in an "obliquely, downwardly directed sliding movement" which is damped by the energy absorbing element. ¶20, p. 10 col. 3:35-49

Identified Points of Contention

  • Scope Questions: The analysis may raise the question of whether the combination of the accused "Rubber Pad" and "Sleeve" meets the functional and structural requirements of the single "energy-absorbing element" as claimed.
  • Technical Questions: A central question will be whether the Accused Product actually produces the claimed "obliquely, downwardly directed sliding movement." The complaint asserts this based on "physical examination," but provides no test data, measurements, or analysis of the product's geometry to substantiate how this specific, complex motion is achieved, as opposed to a more conventional compression and pivot. The evidence required to prove this element may be a key focus of discovery and expert testimony.

V. Key Claim Terms for Construction

"obliquely, downwardly directed sliding movement"

  • Context and Importance: This phrase defines the core inventive concept distinguishing the patent from prior art that may simply pivot or bend. The outcome of the case could depend on whether this term is construed broadly to cover any motion with both downward and lateral vectors, or narrowly to require a specific mechanism or path of travel guided by the interaction of shaped components as described in the patent.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claim language itself is functional, describing the result of the movement rather than specifying the precise structure that causes it. Parties could argue that any device achieving this outcome infringes.
    • Evidence for a Narrower Interpretation: The specification repeatedly links this specific motion to the "cooperation" of beveled or shaped surfaces on the post's flange and the base plate's flange or inner wall. ('677 Patent, col. 3:39-44, col. 6:50-65). A party could argue the term is implicitly limited to the structured, guided motion enabled by these disclosed mechanisms, not just any incidental downward and lateral shifting.

"hollow space formed by the post, an inner wall of the base plate and the ground surface"

  • Context and Importance: Practitioners may focus on this term because it defines the environment of the energy-absorbing element. Infringement requires the accused device to have a cavity with these specific boundaries.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claim language is straightforward. The provided diagram of the accused product appears to show the "Rubber Pad" resting on the ground within the base, which seems to align with the plain meaning of the claim. (Compl. p. 8).
    • Evidence for a Narrower Interpretation: A defendant could argue that if their product has any form of bottom plate, even a thin one, the "ground surface" itself does not form the hollow space. The patent specification contemplates an alternative embodiment with a "bottom plate," suggesting that its absence in Claim 1 is a deliberate limitation. ('677 Patent, col. 7:19-21).

VI. Other Allegations

Willful Infringement

The complaint alleges that Defendant has had knowledge of the ’677 Patent and its infringement since at least the patent's issue date of April 10, 2018. (Compl. ¶31). More pointedly, it alleges that Defendant was sued for infringement of the very same patent in a separate action in the Western District of Texas on September 24, 2024, giving it actual knowledge. (Compl. ¶32). The complaint further alleges that Defendant "implemented the claims" or "reverse engineered Plaintiffs' commercial embodiment" and made no attempt to design around the patent. (Compl. ¶¶25-26).

VII. Analyst’s Conclusion: Key Questions for the Case

  • A core issue will be one of claim scope and construction: can the functional term "obliquely, downwardly directed sliding movement" be met by the accused product, or is the term limited by the specification to a specific, guided motion created by the cooperating beveled surfaces shown in the patent's embodiments?
  • A key evidentiary question will be one of technical proof: what evidence can Plaintiffs present, beyond the conclusory assertion of "physical examination," to demonstrate that the accused bollard's internal components interact to produce the specific, complex sliding motion required by Claim 1, as distinct from a more conventional compression and pivoting action?
  • The allegation that Defendant continued to infringe after being sued on the same patent in a prior case raises a significant question of willfulness, which could expose Defendant to claims for enhanced damages if infringement is found. (Compl. ¶32).
