Global IP Holdings v. Root Sciences: Botanical Extraction Patent Dispute Dismissed After 624 Days
Global IP Holdings LLC filed suit against Root Sciences LLC in the Western District of Washington asserting two patents covering methods to reduce chlorophyll co-extraction in essential oils and aromatic isolates. The case ran for 624 days before being voluntarily dismissed — with the public record silent on whether any settlement drove the exit.
IP Assertion in Botanical Extraction Ends Without Merits Ruling
Global IP Holdings LLC commenced this patent infringement action on 28 February 2023 before Judge Thomas S. Zilly in the Western District of Washington. The plaintiff asserted two patents — US10507407B2 and US10814248B2 — both directed to methods of reducing chlorophyll co-extraction during the isolation of essential oils and aromatic compounds, a technically sensitive step in botanical and cannabis extraction workflows. Root Sciences LLC, the defendant, is a company operating in the extraction equipment and services space.
The case closed on 13 November 2024 via a notice of voluntary dismissal filed by the plaintiff. Voluntary dismissal under the Federal Rules permits a plaintiff to exit the case unilaterally at certain procedural stages, but the public termination record does not specify whether the dismissal was entered with or without prejudice. That distinction is commercially significant: a with-prejudice dismissal extinguishes the claims permanently, while a without-prejudice dismissal preserves the plaintiff’s right to re-file against the same defendant on the same patents.
The 624-day duration before dismissal suggests the parties progressed beyond early procedural skirmishes — litigation of this length typically involves at least some claim construction activity or discovery exchanges, which may have informed the decision to exit. Whether the dismissal reflects a confidential settlement, a licensing agreement, or a unilateral strategic withdrawal by Global IP Holdings cannot be determined from the public record. The absence of a merits ruling leaves the validity and infringement positions of both patents unresolved publicly.

Voluntarily dismissed: what the silent record means for both parties
Voluntary dismissal: a unilateral plaintiff exit with open questions
A notice of voluntary dismissal allows a plaintiff to withdraw its claims without a merits adjudication. Under Federal Rule of Civil Procedure 41, the critical variable is prejudice: if the dismissal is with prejudice, the claims are extinguished; if without, the plaintiff may re-file. The public termination record in this case specifies only ‘voluntary dismissal’ — it does not state which form was filed, leaving enforceability of the exit terms unclear to outside observers.
No merits ruling issuedWith or without prejudice? The public record is silent
The distinction between dismissal with and without prejudice is significant for Root Sciences and any future targets of these patents. With prejudice ends the dispute permanently against this defendant. Without prejudice preserves Global IP Holdings’ ability to reassert US10507407B2 and US10814248B2 against Root Sciences or others. The docket entry recorded here does not resolve that question, and practitioners should review the actual filed notice to determine which form applies before drawing competitive conclusions.
Prejudice status unconfirmedRoot Sciences exits without invalidity finding — exposure persists
Root Sciences achieved dismissal of the action without having to litigate infringement or validity to a merits ruling. However, because no court has adjudicated the patents’ validity or scope, Root Sciences cannot rely on this case as legal precedent to shield it from future assertions. If the dismissal was without prejudice, re-assertion risk remains live. A proactive IPR petition or FTO clearance strategy would strengthen its position against these patents going forward.
No invalidity determinationUnresolved patents remain a sector-wide risk for extraction technology players
US10507407B2 and US10814248B2 cover methods relevant to chlorophyll reduction in botanical extraction — a process step widely used across cannabis, hemp, and essential oil industries. The voluntary dismissal without a validity ruling means these patents retain their presumption of validity and could be asserted against other market participants. Companies developing or deploying extraction workflows in this space should treat these patents as active IP risk until formally invalidated or licensed.

Official order — verbatim text
The recorded verdict — ‘Notice of Voluntary Dismissal’ — reflects a plaintiff-initiated procedural exit rather than a judicial determination on the merits. The termination basis confirms voluntary dismissal but does not specify prejudice status, which is the dispositive factor for future enforcement risk. Practitioners should retrieve the filed Rule 41 notice to confirm whether Global IP Holdings has permanently relinquished its claims against Root Sciences or retains the right to re-file on US10507407B2 and US10814248B2.
US10507407B2 & US10814248B2 — Chlorophyll-Reduction Botanical Extraction Methods
US10507407B2 and US10814248B2 both address a technically specific challenge in botanical extraction: the unwanted co-extraction of chlorophyll alongside target compounds such as cannabinoids, terpenes, essential oils, and aromatic isolates. Chlorophyll contamination degrades product quality and requires costly remediation steps, making its reduction at the extraction stage commercially valuable. The patents were filed under application numbers US16/023531 and US16/681765 respectively, situating them in a period of rapid IP development across the cannabis and botanical processing industries.
From a competitive standpoint, these patents occupy a meaningful position in the extraction technology value chain — covering process-level methods rather than specific apparatus, which typically broadens their potential reach against competitors using functionally equivalent workflows. Any company producing hemp-derived, cannabis-derived, or botanical extracts using solvent, CO2, or hydrocarbon-based systems that incorporate chlorophyll-management steps should evaluate whether their processes fall within the claimed method steps. The patents’ presumption of validity is intact following this case’s dismissal without merits adjudication.
Should your extraction process be cleared against US10507407B2 and US10814248B2?
R&D teams and product managers at companies developing chlorophyll-reduction extraction workflows — whether for cannabis concentrates, hemp extracts, essential oils, or aromatic isolates — face real exposure from these patents. Because the dismissal here produced no invalidity ruling, both patents remain fully enforceable. If your process involves selective extraction steps designed to limit chlorophyll carry-over, a freedom-to-operate analysis is advisable before scaling or commercialising those methods.
PatSnap Eureka’s FTO Search Agent can map your specific extraction process steps against the claim language of US10507407B2 and US10814248B2, surface relevant prior art that could support IPR petitions, and identify design-around opportunities. Given the method-claim structure typical of process patents in this domain, claim-by-claim analysis is essential — Eureka’s agent automates that mapping and flags prosecution history estoppel constraints that affect claim scope interpretation.

What this case signals for the botanical extraction IP landscape
A 624-day voluntary dismissal in W.D. Washington leaves two extraction patents unresolved — and the sector exposed to reassertion.
Long pre-dismissal duration suggests discovery or claim construction shaped the exit
Cases resolved by voluntary dismissal after more than 600 days have typically advanced past early motions practice. In this action, the timeline is consistent with substantive litigation activity — claim construction briefing, expert exchanges, or discovery — before the parties reached whatever private resolution prompted dismissal. Companies monitoring this space should note that the patents’ claim scope may have been stress-tested, even if no public ruling resulted.
Absence of a merits ruling keeps the patent portfolio actionable
Without an invalidity finding, inter partes review decision, or summary judgment order on the record, US10507407B2 and US10814248B2 carry full presumption of validity. Global IP Holdings retains the ability to assert them in future proceedings — against Root Sciences if without prejudice, or against other targets in the essential oils and aromatic isolates extraction market regardless of outcome here.
Global v Root — key questions answered
Global IP Holdings asserted US10507407B2 (application US16/023531) and US10814248B2 (application US16/681765). Both patents cover methods to reduce chlorophyll co-extraction during the production of essential oils and aromatic isolates — a process step relevant to cannabis, hemp, and botanical extraction workflows.
The public record does not disclose the reason for the voluntary dismissal filed on 13 November 2024. The 624-day duration before dismissal is consistent with substantive litigation activity, and the exit may reflect a private settlement, licensing resolution, or strategic withdrawal — but none of these can be confirmed from the docket alone.
The termination record specifies ‘voluntary dismissal’ but does not state whether it was filed with or without prejudice. This distinction is critical: a with-prejudice dismissal extinguishes the claims, while a without-prejudice dismissal preserves Global IP Holdings’ right to re-file against Root Sciences or other defendants on the same patents. The filed Rule 41 notice should be reviewed to confirm.
Both patents cover process methods for reducing chlorophyll co-extraction during botanical extraction — relevant to any company producing cannabis concentrates, hemp extracts, essential oils, or aromatic isolates using extraction workflows that incorporate chlorophyll-management steps. Because no invalidity ruling was issued in this case, both patents retain their presumption of validity and remain enforceable.
The case was filed in the United States District Court for the Western District of Washington (Case No. 2:23-cv-00282) and was presided over by Judge Thomas S. Zilly. It was filed on 28 February 2023 and closed on 13 November 2024, with a total duration of 624 days.
