II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,918,622 - "Portable Perimeter Defense System," issued April 5, 2011 ('622 Patent)
The Invention Explained
- Problem Addressed: Prior art perimeter security systems were often difficult to deploy, cumbersome, required heavy equipment, and lacked sufficient protection against both high-speed vehicle impacts and munitions like shrapnel or combat rounds (ʼ622 Patent, col. 1:35-44).
- The Patented Solution: The invention is a modular, portable barrier system that can be deployed by as few as one person without external power sources. A key feature is a base plate with a non-planar (e.g., arcuate) aft edge designed to create significant frictional force with the ground upon impact, preventing the barrier from being pushed backward (ʼ622 Patent, col. 6:38-50). The design also incorporates a "box-like" front plate with a deceleration zone to provide enhanced ballistic protection (ʼ622 Patent, col. 8:26-34).
- Technical Importance: The technology aimed to provide a rapidly deployable, flexible security solution for dynamic environments, such as military checkpoints or public events, where both vehicle threats and ballistic threats are a concern.
Key Claims at a Glance
- The complaint asserts infringement of at least independent claim 21 (Compl. ¶26).
- Essential elements of claim 21 include:- A portable perimeter defense system comprising a modular barrier.
- The barrier has an upright plate made of a material to protect against munitions and a base plate for positioning on a ground surface.
- The base plate has a non-planar aft edge configured to frictionally engage the ground to prevent horizontal movement upon impact.
 
- The complaint reserves the right to assert other claims, including dependent claims (Compl. ¶26).
U.S. Patent No. 8,215,866 - "Portable Perimeter Defense Barrier And System," issued July 10, 2012 ('866 Patent)
The Invention Explained
- Problem Addressed: This patent, a continuation-in-part of the '622 Patent's application, further addresses the need for a barrier system that is effective on hard surfaces (like asphalt) where anchoring is not feasible and that can use an impacting vehicle's own force against it (ʼ866 Patent, col. 2:16-25).
- The Patented Solution: The invention describes a modular barrier designed to intentionally pivot backward upon impact around its aft edge. This pivoting motion causes a "vehicle engaging interface" (e.g., a saw-toothed edge) on the front of the base plate to lift and engage the underside of the impacting vehicle, halting its momentum. The design also features a wheel assembly that can be pivoted between an engaged state for transport and a disengaged state for deployment (ʼ866 Patent, Abstract; col. 4:1-16).
- Technical Importance: This design provides an unanchored barrier solution that actively uses the physics of a vehicle collision to defeat the threat, a critical development for temporary deployments on hard surfaces.
Key Claims at a Glance
- The complaint asserts infringement of at least independent claim 49 (Compl. ¶55).
- Essential elements of claim 49 include:- A portable perimeter defense system comprising a modular barrier.
- The barrier has an upright plate, a base plate, and a wheel assembly that pivots between engaged and disengaged positions.
- The base plate has a fore edge with a vehicle-engaging interface in a nonlinear configuration.
- Under impact, the barrier pivots about its aft edge, causing the fore edge to engage the impacting vehicle.
 
- The complaint reserves the right to assert other claims, including dependent claims (Compl. ¶55).
III. The Accused Instrumentality
Product Identification
- The accused product is Defendant’s "Portable Bollard TB100" and similar products (Compl. ¶¶15, 18).
Functionality and Market Context
- The complaint describes the TB100 as a newer, smaller barrier with an "omni-directional design" intended for deployment in locations like "heavily traveled narrow walkways" (Compl. ¶15). It is marketed as a "portable barricade system" to block vehicle access to temporary venues (Compl. ¶27).
- The complaint provides Figure 9, an annotated photograph of the TB100, which identifies its primary components as an "Upright Plate" and a "Base Plate" (Compl. ¶29). Functionally, the TB100 is alleged to be deployable alone or in combination to stop a vehicle, and can be linked with a cable system for wider protection (Compl. ¶¶15, 27). The complaint alleges the product is made of material strong enough to stop a 15,000-pound vehicle (Compl. ¶30).
IV. Analysis of Infringement Allegations
U.S. Patent No. 7,918,622 Infringement Allegations
| Claim Element (from Independent Claim 21) | Alleged Infringing Functionality | Complaint Citation | Patent Citation | 
|---|---|---|---|
| a first modular barrier; | The TB100 is alleged to be a modular barrier. | ¶28 | col. 5:20-22 | 
| said modular barrier comprising an upright plate being configured to and being formed of a material to protect against munitions and a base plate for positioning on a ground surface wherein said base plate extends generally parallel to the ground surface and said upright plate extends generally perpendicular to said baše plate; | The TB100 is alleged to have an upright plate and a base plate. The complaint alleges the material is sufficient to stop a 15,000-pound vehicle, and argues under the doctrine of equivalents that this meets the "protect against munitions" limitation. The complaint provides Figure 9, a photo of the TB100, annotated to show the "Upright Plate," "Base Plate," and their perpendicular relationship. | ¶¶28-31, 36-37 | col. 8:4-10, 44-48 | 
| said base plate of said modular barrier comprising a non-planar aft edge configured to frictionally engage the ground surface to prevent horizontal movement of said modular barrier on impact, said non-planar aft edge extending along a portion of the width of said base plate. | The TB100 base plate is alleged to have a non-planar aft edge that frictionally engages the ground to prevent horizontal movement. This is illustrated with Figure 10, a schematic diagram, and Figure 12, a photo from a vehicle impact test showing the aft edge engaging the ground. | ¶¶32-34 | col. 6:38-46 | 
U.S. Patent No. 8,215,866 Infringement Allegations
| Claim Element (from Independent Claim 49) | Alleged Infringing Functionality | Complaint Citation | Patent Citation | 
|---|---|---|---|
| a first modular barrier; | The TB100 is alleged to be a modular barrier comprising an upright plate and base plate. | ¶57 | col. 4:23-24 | 
| said modular barrier comprising an upright plate and a base plate for positioning on a ground surface wherein said upright plate extends generally perpendicular to said base plate and a wheel assembly pivotally attached to said base plate such that said wheel assembly pivots between engaged and disengaged positions; | The TB100 is alleged to include a wheel assembly pivotally attached to the base plate. The complaint alleges in Figure 18, a close-up photo of the TB100's wheel mechanism, that it operates in an "identical manner" to the patented embodiment. The complaint further alleges the assembly pivots between engaged and disengaged positions. | ¶¶59-63 | col. 11:31-44 | 
| said base plate having an aft and fore edge wherein said fore edge, facing the impact direction, comprises a vehicle engage interface in the form of a nonlinear configuration extending along a portion of said base plate fore edge wherein, under sufficient impact forces, said modular barrier pivots about said aft edge and said fore edge engages an impacting vehicle. | The TB100 base plate is alleged to have fore edges with a nonlinear configuration that function as a vehicle engaging interface. Upon impact, the TB100 allegedly pivots on its aft edge, causing the fore edge to engage the vehicle. This theory is supported by Figure 21, an annotated photo of a crash test showing the "nonlinear configuration," and Figure 22, which depicts the alleged pivoting motion and vehicle engagement during the collision. | ¶¶64-66 | col. 4:1-16; 8:5-10 | 
Identified Points of Contention
- Scope Questions: A central question for the ʼ622 Patent will be whether the bollard-style TB100, allegedly made of material "strong enough to assist in stopping a 15,000 pound vehicle" (Compl. ¶37), can be read on the claim limitation "formed of a material to protect against munitions." The complaint’s alternative pleading under the doctrine of equivalents for this element signals an expected dispute over its literal scope (Compl. ¶36).
- Technical Questions: For the ʼ866 Patent, the analysis may focus on whether the accused TB100's wheel assembly operates in the same way as the claimed assembly. The complaint makes a direct visual comparison between the TB100's wheel mechanism and a figure from the '622 Patent (Compl. ¶61), suggesting this is a key factual point of the infringement case.
V. Key Claim Terms for Construction
Term: "upright plate being configured to and being formed of a material to protect against munitions" ('622 Patent, claim 21)
- Context and Importance: This term's construction is critical because the accused product is primarily marketed for vehicle stopping, not ballistic protection. The complaint preemptively argues for infringement under the doctrine of equivalents (Compl. ¶36), suggesting Plaintiff anticipates a narrow construction. The outcome of this construction could determine literal infringement.
- Intrinsic Evidence for Interpretation:- Evidence for a Broader Interpretation: The specification discusses the material in terms of performance standards, stating it "performed at or above" standards like "NIJ Level IV" and "ASTM Rifle AP" ('622 Patent, col. 8:12-14). A party might argue any material meeting these standards qualifies, regardless of its primary marketing.
- Evidence for a Narrower Interpretation: The specification describes a specific "box-like configuration" with a "decelerating zone" filled with "fiberglass or Kevlar" as the unique structure that provides ballistic protection ('622 Patent, col. 8:1-34). A party could argue the term requires this specific multi-component structure, not just a single piece of strong material.
 
Term: "wheel assembly pivots between engaged and disengaged positions" ('866 Patent, claim 49)
- Context and Importance: Practitioners may focus on this term because the ease of deployment is a core inventive concept. The complaint heavily relies on visual comparisons to allege the accused wheel assembly is "identical" (Compl. ¶61), making the specific mechanics of the "pivot" and the definitions of "engaged" and "disengaged" central to the infringement analysis.
- Intrinsic Evidence for Interpretation:- Evidence for a Broader Interpretation: The claim language is functional. A party could argue that any mechanism allowing the wheels to be lowered for transport and raised for static deployment meets the limitation, regardless of the specific mechanical implementation.
- Evidence for a Narrower Interpretation: The specification, by reference to the '622 patent, describes a specific mechanism involving a "fork 61" rotating around a "pivot 63" and being secured by a "pin 65" in "pin holes 64" ('622 Patent, Fig. 12; col. 10:9-19). A party might argue that "pivots" requires this specific type of pinned rotational movement.
 
VI. Other Allegations
Indirect Infringement
- The complaint alleges induced infringement for both patents. It claims Defendant took active steps with the specific intent to cause infringement by "advising or directing customers," "advertising and promoting," and distributing "specifications and instructions (both written and video) that guide users to use the TB100 in an infringing manner" (Compl. ¶¶42, 73).
Willful Infringement
- The complaint alleges that Defendant had actual knowledge of the '622 and '866 patents and its alleged infringement as of at least June 8, 2023, the date of Plaintiff's notice letter (Compl. ¶¶43, 74). It is alleged that Defendant's continued infringement after this date was willful, making the case exceptional and justifying treble damages (Compl. ¶¶48, 79).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope and equivalence: Can the term "upright plate... formed of a material to protect against munitions" from the ’622 Patent, which describes a specific dual-panel, bullet-decelerating construction, be construed to cover the single-component, vehicle-stopping structure of the accused TB100 bollard, either literally or under the doctrine of equivalents?
- A key evidentiary question will be one of functional and structural identity: Does the accused TB100's wheel assembly, as depicted in the complaint's photographs, operate in the same way to achieve the same result as the pivoting wheel assembly claimed in the ’866 Patent, particularly given the complaint’s assertion that they operate in an "identical manner"?
- A third central question will be one of technical operation: Does the accused TB100, upon impact, actually perform the pivoting motion claimed in the '866 patent, where the barrier's fore edge lifts to engage the underside of the vehicle, or does it stop the vehicle through a different mechanical action? The complaint’s reliance on crash test photos makes this a central factual dispute.
