L DFM Logan Wade Archer v. Summit Plastering Inc
Key Events
Complaint
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Logan Wade Archer (California)
- Defendant: Summit Plastering, Inc. (California)
- Plaintiff’s Counsel: Rutan & Tucker, LLP
- Case Identification: 8:18-cv-00217, C.D. Cal., 02/07/2018
- Venue Allegations: Venue is alleged to be proper as Defendant resides in, has a regular and established place of business in, and has committed alleged acts of infringement within the judicial district.
- Core Dispute: Plaintiff alleges that Defendant’s scaffolding attachment system infringes a patent related to methods for securing scaffolding to buildings, and that Defendant's conduct also constitutes a breach of prior settlement agreements between the parties.
- Technical Context: The technology pertains to mechanical anchoring systems used in the construction industry to safely affix temporary scaffolding to a building’s structural frame.
- Key Procedural History: The complaint details a significant history of prior disputes between the parties over the same patent. An initial patent infringement lawsuit in 2013 was resolved by a 2014 settlement agreement in which Defendant allegedly agreed not to sell the original accused products. A subsequent state court action for breach of that agreement was resolved by a second settlement in 2016, which the complaint states reaffirmed the original obligations. This history may be central to the allegations of willful infringement.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 8,316,992 - "Method and Apparatus for Securing a Scaffold to a Building"
- Patent Identification: U.S. Patent No. 8,316,992, "Method and Apparatus for Securing a Scaffold to a Building," issued November 27, 2012.
The Invention Explained
- Problem Addressed: The patent describes conventional methods of attaching scaffolding to buildings, such as using tie wires or welding, as potentially insecure, time-consuming, and labor-intensive (’992 Patent, col. 4:1-11). There is a need for a more secure and efficient connection method that also protects the building from moisture intrusion after installation (’992 Patent, col. 6:8-18).
- The Patented Solution: The invention is an anchoring system designed to be partially and permanently embedded in a building’s wall. It consists of a base member with an attached, threaded coupling that is secured to a building's structural frame. A key feature is a flange that extends from the coupling and is positioned between an internal structural layer (e.g., sheathing) and the final outer finish layer (e.g., stucco) (’992 Patent, col. 2:1-3, Fig. 1). This allows a scaffold’s connecting post to be securely and removably attached to the coupling during construction, and once the scaffold is removed, the embedded coupling can be sealed and permanently covered by the final finish (’992 Patent, col. 8:1-15).
- Technical Importance: This design provides a structurally sound and reusable anchor point for scaffolding while integrating seamlessly with the building finishing process, aiming to enhance both safety and construction efficiency (’992 Patent, col. 4:12-18).
Key Claims at a Glance
- The complaint asserts independent claim 1 and reserves the right to assert dependent claims (Compl. ¶15, ¶18).
- The essential elements of independent claim 1 include:
- A latticework of members for a scaffold platform;
- A "base member" secured to a structural component of the building;
- A "coupling member" with an internal thread, secured to the base member;
- The "base member extending radially outwardly along a rear face of the coupling member forming a flange" around it;
- The "flange being disposed inwardly from", and in a separate plane from, a final outer finish layer, such that the flange is "between the finish layer and an internal layer of the building";
- The coupling member having a length less than the thickness of the final outer finish layer; and
- A "connecting member" with an external thread to mate with the coupling member and attach to the latticework.
III. The Accused Instrumentality
Product Identification
- The complaint identifies the accused product as a "slightly modified post/plate system," referred to in the claim chart as the "Summit Plastering System" (Compl. ¶15; p. 5).
Functionality and Market Context
- The complaint alleges the accused product is a scaffolding attachment system made, used, and sold by the Defendant (Compl. ¶15). According to the infringement allegations, the system includes a "circular or washer-shaped base member," a "coupling member - a hex nut," and a connecting member that threads into the nut to support scaffolding (Compl. p. 5). The complaint includes a photograph of the accused system installed on a building, showing a connecting post extending from a finished wall surface (Compl. ¶15, Image). The complaint does not provide further detail on the product's market context beyond the allegations of infringing sales.
IV. Analysis of Infringement Allegations
’992 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A scaffolding system consisting of: a latticework of members defining at least one platform, connected to a building for supporting workers adjacent to the building; | The Summit system is used with a latticework of members for a scaffold platform connected to a building. | ¶16 | col. 4:36-43 |
| a base member secured to a structural component of the building; | The system uses a "circular or washer-shaped base member" secured to a structural component of the building. | ¶16 | col. 5:56-62 |
| a coupling member secured to the base member, the coupling member having an internal thread, | The system uses a "coupling member - a hex nut" which has an internal thread. | ¶16 | col. 4:64-65 |
| the base member extending radially outwardly along a rear face of the coupling member forming a flange around the coupling member, | The base member is described as a "washer" that "extends radially outwardly along a rear face of the coupling member" and forms a "flange (a protecting flat rim or collar)." | ¶16 | col. 2:63-65 |
| the flange being disposed inwardly from, in a separate plane from and adjacent to a position of a final outer finish layer of the building wherein the flange is between the finish layer and an internal layer of the building, | The flange is alleged to be disposed inwardly from and between the final and internal layers of the building. | ¶16 | col. 2:1-3 |
| the coupling member having a longitudinal length, along an axial direction of the internal thread, that is less than a thickness of the final outer finish layer such that an outer plane of the final outer finish layer extends beyond an outermost portion… | The complaint alleges the coupling member has a longitudinal length along the axial direction of the internal thread. | ¶16 | col. 2:3-5 |
| a connecting member having a first end and a second end, the first end having an external thread configured to mate with the internal thread, the second end being attached to the latticework... | The system has a connecting member with an external thread that mates with the internal thread of the hex nut and attaches to the latticework. | ¶16 | col. 2:4-8 |
Identified Points of Contention
- Scope Questions: The complaint alleges the accused product is a "slightly modified" version of a previously disputed product (Compl. ¶15). A primary point of contention may be whether the combination of a separate "washer-shaped base member" and a "hex nut" (the coupling member) meets the claim limitation of a "base member... forming a flange." This raises the question of whether the claim requires a unitary or integrated component, or if an assembly of standard hardware components can satisfy the limitation.
- Technical Questions: The photograph of the accused system shows the connecting member emerging from a finished wall (Compl. ¶15, Image). However, a key factual question for the court will be whether the accused "washer" is, in practice, actually installed "between the finish layer and an internal layer of the building" as required by the claim. Evidence regarding the physical installation process and final positioning of the components within the wall structure will be critical.
V. Key Claim Terms for Construction
The Term: "base member"
Context and Importance: The complaint alleges a "washer" is the "base member". Practitioners may focus on this term because the patent figures depict the "base member" as a more substantial plate to which a coupling is affixed (e.g., '992 Patent, Fig. 3, 124), not a standard, off-the-shelf washer. The construction of this term will be critical to determining if the accused system's components map onto the claimed elements.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification states the base can be made from various "rigid materials" and that its "shape, size, thickness and other properties... can vary," which could support construing the term to cover a simple washer ('992 Patent, col. 5:30-33).
- Evidence for a Narrower Interpretation: The patent repeatedly describes and depicts the base as a plate to which the coupling is "securely joined" or attached, suggesting a prepared, purpose-built component rather than a generic washer used in a conventional nut-and-washer assembly ('992 Patent, col. 5:26-27; Fig. 1, 3, 5).
The Term: "the base member extending radially outwardly along a rear face of the coupling member forming a flange"
Context and Importance: This limitation describes the structural relationship between the base and the coupling. The infringement allegation hinges on whether a separate washer placed against a hex nut can be considered a "base member... forming a flange." This term’s construction will likely determine whether an assembly of discrete components infringes a claim that may be read to describe a more integrated structure.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The phrase "forming a flange" could be interpreted functionally; if the washer, when assembled with the nut, creates the functional flange described in the patent, it may be found to infringe. The patent notes that in some embodiments the coupling and base are a "unitary member," implying they are not required to be so in all cases ('992 Patent, col. 5:50-51).
- Evidence for a Narrower Interpretation: The claim language "base member extending... forming" suggests a single part with a feature, not two separate parts assembled together. The specification refers to a "base portion" comprising a "flange portion extending radially from the coupling portion," which could be interpreted as describing an integrated unit ('992 Patent, col. 2:35-37).
VI. Other Allegations
- Indirect Infringement: The complaint alleges both contributory and inducing infringement, stating that Defendants know users of their system infringe the ’992 Patent and that they "actively encourage the use of such system in an infringing manner" (Compl. ¶18).
- Willful Infringement: The complaint alleges that infringement is "willful, wanton and deliberate with full knowledge and awareness of Plaintiff's patent rights" (Compl. ¶19). This allegation is factually supported by the extensive litigation history recited in the complaint, including a prior infringement action on the same patent and two settlement agreements that allegedly resolved prior infringing conduct (Compl. ¶10-14).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of structural scope: can the claim language "base member... forming a flange" be construed to read on an assembly of two separate, standard hardware components (a washer and a hex nut), or does the patent require a single, integrated component?
- A key evidentiary question will be one of factual infringement: does the evidence show that Defendant's accused system is installed such that the "washer-shaped base member" is physically located "between the finish layer and an internal layer of the building," as strictly required by the asserted claim?
- Given the documented history of prior litigation and settlement, a central question for damages will be willfulness: was the "slightly modified" accused product a good-faith attempt to design around the patent claims, or does its introduction constitute deliberate infringement in light of Defendant's established knowledge of the patent?
