Log In

I. Executive Summary and Procedural Information

  • Parties & Counsel:
  • Case Identification: 1:20-cv-10433, D. Mass., 05/26/2020
  • Venue Allegations: Venue is alleged to be proper as all defendants are residents of or incorporated in Massachusetts and have committed the alleged acts of infringement within the district.
  • Core Dispute: Plaintiffs allege that Defendant Florence, a former business partner of Plaintiff Eldredge, improperly omitted Eldredge as a co-inventor on, and wrongfully transferred ownership of, a patent for a runoff water management system to an entity controlled by Florence and his daughter, which is now infringing that patent.
  • Technical Context: The technology relates to subsurface drywell systems used to manage stormwater runoff, a common component in residential and commercial landscaping and construction.
  • Key Procedural History: The complaint details a complex business dispute between former partners Eldredge and Florence. It alleges an agreement to form a joint IP holding company (JTIP), to which the patent-in-suit was to be assigned. The complaint alleges the patent was initially assigned to JTIP but was later improperly transferred by Florence to a new entity, FloPack, LLC, without the consent of JTIP's members. The complaint asserts claims for correction of inventorship and patent infringement, alongside various state-law business torts.

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

  • U.S. Patent No. 10,364,563, "Runoff Water Management System," issued July 30, 2019 (’563 Patent)

The Invention Explained

  • Problem Addressed: The patent's background describes limitations of prior art drywells, which are essentially underground reservoirs for surface water. These systems can become ineffective when surrounding soil clogs the outflow ports or when water dispersion is limited primarily to the bottom of the reservoir, leading to localized soil saturation and reduced leaching capacity (Compl. ¶33-¶34; ’563 Patent, col. 2:1-30).
  • The Patented Solution: The invention is a drywell apparatus featuring a plurality of "interior diverters" mounted inside the drywell over the sidewall drain ports (’563 Patent, col. 4:40-44). These diverters are designed to direct water outflow laterally into the surrounding soil, starting from the uppermost ports, which is claimed to increase the overall size of the underground water "plume" and improve drainage efficiency (’563 Patent, col. 3:1-7). The diverters also serve to block backfill soil from entering and clogging the drain ports (’563 Patent, Abstract; col. 6:20-23). The complaint alleges Plaintiff Eldredge conceived of key aspects of this diverter box design (Compl. ¶35).
  • Technical Importance: The design purports to offer a more effective water management solution by enhancing subsurface water dispersion and preventing common failure modes like clogging, potentially reducing the excavation footprint and cost associated with traditional stone-filled drywells (’563 Patent, col. 3:11-16).

Key Claims at a Glance

  • The complaint asserts infringement of "the claims of the ‘563 Patent" without specifying which ones (Compl. ¶104). The patent contains one independent claim.
  • Independent Claim 1 recites an apparatus comprising:
    • A drywell with a top port, an open bottom, and a cylindrical sidewall with multiple rectangular drain ports.
    • A plurality of "interior diverters" attached to the interior surface of the sidewall, with each diverter positioned about one of the drain ports.
    • A detailed recitation of the structure of the interior diverter, including a specific two-part rear section, "downwardly extending flanges" at its bottom, and "holding tabs" at its top.
    • A description of how the diverter attaches to and functions with the sidewall to receive water and disperse it laterally through the drain port while preventing backfill intrusion.
  • The complaint notes that Plaintiff Eldredge contributed to the invention recited in "Claims 1, 2, and 3" (Compl. ¶35).

III. The Accused Instrumentality

Product Identification

The complaint does not identify a specific accused product by name. It alleges infringement through the defendants' acts of "making, using, offering for sale, selling, distributing... the ‘563 Patent technology" (Compl. ¶104).

Functionality and Market Context

The accused instrumentality is described as the commercial embodiment of the ’563 Patent (Compl. ¶104; Relief Sought ¶3). The complaint alleges that Defendant FloPack, LLC was formed for the purpose "To make, license, acquire, and market water management devices" and that the ’563 Patent is the only patent assigned to it (Compl. ¶78, ¶81). The infringement allegations are directed at products embodying this patented technology being commercialized by Defendants FloPack and Perry (Compl., COUNT III).

IV. Analysis of Infringement Allegations

The complaint does not provide element-by-element infringement allegations, a claim chart, or technical details about how any specific product infringes the asserted patent. The infringement count is pleaded in general terms, alleging that Defendants FloPack and Perry are making, using, or selling the "‘563 Patent technology" without a license from the alleged rightful owner, Plaintiff JT IP Holding (Compl. ¶104). The central dispute articulated in the complaint is over ownership and inventorship, with the infringement claim being contingent on the resolution of those threshold issues.

Identified Points of Contention

  • Ownership and Standing: A threshold legal question is whether Plaintiff JT IP Holding has standing to assert the ’563 Patent. The case's outcome will depend on the court’s determination of the validity of the competing patent assignments: the initial assignment to Plaintiff JT IP (Compl. ¶45) versus the subsequent assignment to Defendant FloPack (Compl. ¶71). If the transfer to FloPack is deemed valid, the infringement claim against it would fail.
  • Technical Questions: Assuming the ownership issue is resolved in Plaintiffs' favor, a key evidentiary question will be whether any product made or sold by Defendants embodies every limitation of an asserted claim. The complaint provides no facts to support this. For example, what evidence will show that a product manufactured by Defendants includes an "interior diverter" with the specific two-part rear section, flanges, and holding tabs recited in Claim 1?

No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

  • The Term: "interior diverter"
  • Context and Importance: This term appears in independent Claim 1 and is the central inventive concept described in the patent. The infringement analysis for Claim 1 will depend entirely on whether an accused product contains a structure that meets the definition of an "interior diverter" as claimed. Practitioners may focus on this term because Claim 1 provides a highly detailed structural definition, creating a likely battleground for claim construction.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification also discloses an alternative embodiment with an exterior diverter (e.g., diverter strip 21) (’563 Patent, col. 4:20-30). A party could argue that "diverter" is a generic concept and that "interior" merely specifies its location, suggesting the term should not be confined to the exact embodiment shown in Figures 8-12.
    • Evidence for a Narrower Interpretation: Claim 1 itself acts as a lexicon by defining the "interior diverter" with extensive structural detail, including its "front, rear, open top, bottom, and two opposite, identical sides," a rear section that "is divided into two sections," "downwardly extending flanges," and "holding tabs" (’563 Patent, col. 6:3-16). A party would argue this detailed recitation confines the scope of the term to a structure possessing all of these specific features, as depicted in the patent's figures for interior diverter 40 (e.g., Fig. 10-12).

VI. Other Allegations

  • Indirect Infringement: The complaint alleges that Defendants are "actively inducing infringement" (Compl. ¶105). However, it does not plead specific facts to support this, such as referencing user manuals, advertisements, or other materials that allegedly instruct customers to use a product in an infringing manner.
  • Willful Infringement: Willfulness is alleged based on Defendants' purported pre-suit knowledge of the patent and of Plaintiff JT IP's ownership rights (Compl. ¶106). The complaint's narrative suggests that Defendants Florence and Perry were fully aware of the patent and JT IP's claims to it when they allegedly transferred the patent to FloPack and began commercializing the technology (Compl. ¶71, ¶82).

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

This litigation appears to be primarily a business ownership dispute masquerading as a patent infringement case. The central questions for the court will likely be:

  1. A threshold question of ownership and standing: Is Plaintiff JT IP Holding, LLC the rightful owner of the ’563 Patent, or was the subsequent assignment to Defendant FloPack, LLC valid? The viability of the patent infringement claim is entirely contingent upon the answer.
  2. A secondary question of inventorship: Was Plaintiff Eldredge a contributor to the conception of the claimed invention, and should he be added as a co-inventor? The resolution of this issue could affect the chain of title and the validity of the patent assignments.
  3. A final evidentiary question of infringement: Assuming Plaintiffs can establish ownership, can they produce evidence that an actual product sold by Defendants practices the highly detailed structural limitations of the asserted claims, particularly the specific "interior diverter" structure defined in Claim 1?
