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

U.S. Patent No. 9,851,030 - Connecting Apparatus for Creating a Connection Between a Measuring Instrument/Valve Block and a Pipeline

The Invention Explained

• Problem Addressed: The patent's background describes a problem in industrial pipeline monitoring, where installing two conventional connecting apparatuses close together is difficult or impossible. This is because the shutoff valve on one apparatus physically collides with the other apparatus when it is being rotated and screwed into place, a necessary step for installation ('030 Patent, col. 2:1-14).
• The Patented Solution: The invention is a multi-part connecting apparatus comprising a first connecting device (for the pipeline), a second connecting device (for the measuring instrument), and a separate "connecting unit." The design allows a technician to first attach the connecting devices without fully tightening them, and then create the final, secure seal by rotating only the connecting unit. This eliminates the need to rotate the main bodies of the apparatuses, thereby avoiding the collision problem ('030 Patent, Abstract; col. 2:60-68).
• Technical Importance: This approach allows for the "simple and fast installation" of connectors with integrated shutoff valves in the compact configurations required for reliable differential pressure measurement, a common industrial application ('030 Patent, col. 2:55-59).

Key Claims at a Glance

• The complaint asserts infringement of at least independent claim 1 ('030 Patent, Compl. ¶30).
• Essential elements of independent claim 1 include:
  • A first connecting device connectable to a pipeline.
  • A second connecting device connectable to a measuring instrument or valve block.
  • A "connecting unit" that provides a sealing connection between the first and second connecting devices.
  • A design wherein the sealing connection is created "solely by rotation of the connecting unit without rotating the first and second connecting devices."
  • Specific structural features, including an "outwardly pointing outer flange" on the first device, a male thread on the second device, and the connecting unit being a "nut unit with a female thread and an inwardly pointing inner flange."
• The complaint does not explicitly reserve the right to assert dependent claims but alleges infringement of "one or more claims" ('030 Patent, Compl. ¶22).

III. The Accused Instrumentality

Product Identification

The accused product is RJ Machine’s “AXIS” stabilized connector ('030 Patent, Compl. ¶22).

Functionality and Market Context

The AXIS connector is described as an instrument valve and manifold for industrial applications, such as natural gas pipelines ('030 Patent, Compl. ¶19). The complaint provides visual evidence, including photographs of the Accused Product displayed for sale at an industry trade show ('030 Patent, Compl. p. 6). Another figure provides an annotated diagram of the product, identifying an "Upper body," a "Lower body," and a "Union hex nut" which "allows the upper and lower bodies of the connector to be installed to their mating parts and integrate the two bodies as a complete assembly" ('030 Patent, Compl. p. 7). Plaintiff alleges that Defendant has used the Accused Product to "displace and undercut AS-Schneider products" in the market ('030 Patent, Compl. ¶36, 49).

IV. Analysis of Infringement Allegations

The complaint references an "exemplary claim chart detailing RJ Machine's infringement of claim 1" as Exhibit B, but this exhibit was not attached to the filed complaint ('030 Patent, Compl. ¶29). In lieu of a chart, the infringement theory can be summarized from the complaint's narrative and visual allegations.

The core of the infringement allegation is that the structure and function of the Defendant's "AXIS" connector directly correspond to the elements of claim 1 of the ’030 Patent. The complaint's annotated diagram of the AXIS connector appears to map its components to the patented invention: the "Lower body" corresponds to the claimed "first connecting device," the "Upper body" corresponds to the "second connecting device," and the "Union hex nut" corresponds to the "connecting unit" ('030 Patent, Compl. p. 7). The annotation stating that the nut "integrate[s] the two bodies" suggests it performs the claimed function of creating a connection between the two main components, allegedly without requiring them to be rotated ('030 Patent, Compl. p. 7).

• Identified Points of Contention:
  • Scope Questions: A central question will be whether the components of the "AXIS" connector meet the specific structural limitations recited in claim 1. For example, does the Defendant's "Lower body" possess an "outwardly pointing outer flange," and does its "Union hex nut" possess an "inwardly pointing inner flange," as strictly required by the claim language ('030 Patent, col. 8:64-65; col. 9:2-4)?
  • Technical Questions: The infringement analysis will likely focus on whether the Accused Product's "Union hex nut" creates the seal "solely by rotation" of the nut itself, without rotating the upper and lower bodies. The complaint alleges this functionality, but the degree to which this occurs in the actual operation of the AXIS connector will be a key factual determination for the court.

V. Key Claim Terms for Construction

• The Term: "connecting unit"

• Context and Importance: This term describes the central component that distinguishes the invention from prior art. The infringement case depends on whether the accused "Union hex nut" is properly characterized as the claimed "connecting unit."

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification generally describes the component's function: "for the sealing connection of said first and second connecting devices" ('030 Patent, col. 2:62-64).
  • Evidence for a Narrower Interpretation: Claim 1 itself provides a highly specific structural definition, stating the connecting unit is "designed as a nut unit with a female thread and an inwardly pointing inner flange which is arranged in the lower edge region" ('030 Patent, col. 9:1-4). A defendant may argue this language limits the term's scope to this precise configuration.

• The Term: "solely by rotation of the connecting unit without rotating the first and second connecting devices"

• Context and Importance: This functional language captures the core operational benefit of the invention. Practitioners may focus on this term because proving that the accused product operates in this specific manner is essential for a finding of literal infringement.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The phrase is functional and could arguably cover any mechanism where the final clamping force is applied by a third piece without requiring the primary components to turn.
  • Evidence for a Narrower Interpretation: The specification repeatedly emphasizes this exact sequence of operations as the solution to the prior art collision problem, suggesting it is a critical and specific limitation, not a general concept ('030 Patent, col. 7:1-4; col. 7:51-58).

VI. Other Allegations

• Indirect Infringement: The complaint alleges that RJ Machine induces infringement by its customers under 35 U.S.C. § 271(b). The factual basis for this claim is the allegation that Defendant "actively advertises, instructs, and encourages users—e.g., product documentation—to use and implement the Accused Product in a manner that infringes" ('030 Patent, Compl. ¶43).
• Willful Infringement: The complaint alleges willful infringement based on both pre- and post-notice conduct. Pre-notice knowledge is alleged based on Defendant’s hiring of two of Plaintiff’s former employees who were allegedly "aware of the '030 Patent" and had access to confidential specifications for Plaintiff's competing product ('030 Patent, Compl. ¶20-22, 32). Post-notice willfulness is alleged based on Defendant’s continued marketing and sale of the Accused Product after receiving Plaintiff's July 7, 2023 cease-and-desist letter, which explicitly identified the patent and the accused product ('030 Patent, Compl. ¶23, 25, 34).

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

The resolution of this dispute will likely depend on the court's findings on two central issues:

1. A core issue will be one of claim scope and structural equivalence: Does the accused "AXIS" connector, with its "Upper body," "Lower body," and "Union hex nut," possess the specific structural features—such as the "outwardly pointing outer flange" and "inwardly pointing inner flange"—that are explicitly recited in the asserted independent claim?

2. A key evidentiary question will be one of copying and intent: What evidence supports the allegation that Defendant copied Plaintiff's patented design, particularly in light of the claims involving former employees with access to confidential information? The answer to this question will be highly relevant to the determination of damages and willfulness.
