US Conec v. Changzhou Co-net (337-TA-1399): ITC Fiber Optic Connector Case Settled in 203 Days
US Conec, Ltd. filed a Section 337 investigation at the US International Trade Commission against Changzhou Co-net Electronic Technology, asserting six fiber optic connector patents covering MPO connectors, push-pull boots, and alignment adapters. The case settled within 203 days — a notably swift resolution for an ITC proceeding.
Six-patent ITC broadside settled before evidentiary hearing
On 22 March 2024, US Conec, Ltd. — a North Carolina-based manufacturer and IP licensor in the fiber optic connectivity space — initiated ITC Investigation No. 337-TA-1399 against Changzhou Co-net Electronic Technology Co., Ltd., a Chinese connector manufacturer. US Conec asserted six US patents covering core fiber optic connector technologies including reversible-polarity MPO connectors, mini duplex push-pull connectors, alignment adapters, and flexible crimp boots. Administrative Law Judge Monica Bhattacharyya was assigned to preside.
The investigation closed on 11 October 2024 after just 203 days, with the ITC recording a settlement as the basis of termination. In ITC practice, settlement typically triggers a motion to terminate the investigation, which the Commission grants upon finding the agreement does not adversely affect the public interest. No exclusion order or cease-and-desist order was issued, suggesting the parties resolved the dispute through a negotiated arrangement — most likely a licensing agreement or cross-license, though the specific terms are not publicly available.
A 203-day resolution is notably rapid for a Section 337 investigation, where the statutory target is a final determination within 15–18 months of institution. Early settlement likely reflects the breadth and commercial weight of US Conec’s six-patent portfolio, the cost and disruption risk of an ITC exclusion order for an import-dependent respondent, and possible commercial incentives on both sides. The precise financial or licensing terms remain confidential, leaving the full strategic outcome unknown from the public record.

ITC investigation terminated by settlement: what this means for both parties
Settlement terminates ITC investigation before final ruling
Under 19 C.F.R. § 210.21, parties to a Section 337 investigation may move to terminate proceedings based on a settlement agreement. The ITC grants such motions if it finds the settlement does not adversely affect the public interest. Termination by settlement means no exclusion order is issued and the Commission makes no finding on patent validity or infringement — the record closes without a merits determination.
No exclusion order issuedUS Conec secures resolution without full ITC trial
For US Conec, settlement at this stage suggests its six-patent portfolio exerted sufficient leverage to bring Changzhou Co-net to the table well before an evidentiary hearing. The ITC forum — with its exclusion order remedy directly targeting imports — is typically chosen precisely for this coercive effect. Settlement likely delivered commercial value (potentially licensing revenue) without the cost and duration of a full investigation, though the absence of a public merits ruling means the patents’ validity is not adjudicated.
Likely licensing outcomeChangzhou Co-net avoids exclusion order risk through settlement
For Changzhou Co-net, settling early eliminates the existential risk of a general exclusion order or limited exclusion order that would have barred its fiber optic connector products from US import. As an import-dependent Chinese manufacturer, an ITC exclusion order would directly disrupt US market access. The settlement — while involving undisclosed terms — likely preserves some form of ongoing US market participation, consistent with a licensing or cross-licensing arrangement.
US market access preservedITC Section 337 remains a potent tool against connector imports
This case reinforces the ITC’s effectiveness as a forum for US fiber optic IP holders facing foreign import competition. Filing a multi-patent Section 337 complaint — particularly covering a broad product family including MPO connectors, push-pull boots, and alignment adapters — creates concentrated pressure that often resolves before trial. R&D teams and importers in the fiber optic connectivity sector should treat a six-patent ITC complaint as a signal of serious enforcement intent, even where the public record ultimately shows only ‘settled’.

Official order — verbatim text
The ITC’s termination record reflects ‘Case Settled’ with ‘Participant Disposition: Settlement’ — standard Commission language indicating the parties jointly moved to terminate under 19 C.F.R. § 210.21. This phrasing confirms no infringement finding, no validity determination, and no public interest bar to termination was identified. For both parties, the settlement closes the public litigation record without establishing precedent on any of the six asserted patents. The underlying agreement — and any licensing, royalty, or market-access terms — remains confidential.
US11880075B1 and five further US Conec fiber optic connector patents
The six asserted patents — US11880075B1, US11733466B2, US11906794B2, US10495823B2, US11808994B1, and US11385415B2 — cover a coordinated suite of fiber optic connector technologies. The portfolio spans alignment adapter designs, push-pull boot and crimp body assemblies, mini duplex connector polarity mechanisms, and reversible-polarity MPO (multi-fiber push-on) connectors. Application filing dates across the family span from the US15/800883 application through to US18/483949, suggesting an active continuation prosecution strategy that refreshes coverage on maturing product platforms.
MPO connectors are the backbone of high-density fiber deployments in data centres, telecommunications infrastructure, and enterprise networking. US Conec is a recognised innovator in this space, and a six-patent portfolio covering both mechanical interface design and polarity-switching functionality represents significant market coverage. For competitors importing or distributing LC duplex, MPO, or mini duplex connector assemblies into the US, this patent family creates meaningful FTO risk — particularly given that US Conec has now demonstrated willingness to pursue Section 337 relief at the ITC.
Should your fiber optic connector products be cleared against US Conec’s portfolio?
Any company manufacturing, importing, or distributing MPO connectors, mini duplex connectors, alignment adapters, or push-pull boot assemblies in the US market should treat the six patents asserted in this investigation as live FTO concerns. US Conec’s demonstrated ITC enforcement posture — and the rapid settlement outcome that suggests licensing leverage was exercised successfully — means the risk of a follow-on Section 337 complaint against other market participants cannot be discounted.

What this case signals for the fiber optic connector IP landscape
US Conec’s rapid ITC settlement confirms the coercive power of multi-patent Section 337 complaints in the connectivity hardware sector.
Multi-patent ITC filings compress settlement timelines dramatically
By asserting six patents across a coordinated product family — MPO connectors, push-pull mechanisms, alignment adapters, and crimp boots — US Conec created a multi-front validity and infringement burden for Changzhou Co-net. Defending against six patents in an ITC proceeding, where depositions and expert reports run concurrently, is extraordinarily resource-intensive. This portfolio breadth likely accelerated settlement negotiations well ahead of the evidentiary hearing schedule.
ITC exclusion order threat is the decisive lever for import-dependent respondents
Changzhou Co-net’s position as a Chinese manufacturer selling into the US market made it uniquely vulnerable to Section 337’s exclusion order remedy. Unlike a district court damages action, an ITC exclusion order operates at the border — no finding of willfulness or damages calculation required. For companies whose business model depends on US import access, the rational response to a well-pleaded ITC complaint is often early settlement, which this case appears to confirm.
US v Changzhou — key questions answered
US Conec asserted six patents: US11880075B1, US11733466B2, US11906794B2, US10495823B2, US11808994B1, and US11385415B2. The portfolio covers fiber optic connector technologies including alignment adapters, push-pull boot and crimp body assemblies, mini duplex polarity mechanisms, and reversible-polarity MPO connectors.
The investigation was terminated by settlement on 11 October 2024, approximately 203 days after filing. The ITC recorded ‘Case Settled’ as the basis of termination. No exclusion order or cease-and-desist order was issued. The specific terms of the settlement are not publicly available.
A Section 337 complaint at the ITC exposes importers to exclusion orders that bar products at the US border — a direct threat to US market access independent of any damages calculation. For import-dependent manufacturers like Changzhou Co-net, this remedy is typically more commercially threatening than a district court patent action, which may explain the early settlement in this case.
US Conec was represented by M. Scott Stevens of Alston & Bird, LLP. Changzhou Co-net was represented by Timothy David Krieger of Stinson LLP. Administrative Law Judge Monica Bhattacharyya of the USITC was assigned to preside over the investigation.
No. Settlement termination under 19 C.F.R. § 210.21 results in no infringement finding, no validity determination, and no Commission opinion on the merits. The six asserted patents remain fully enforceable and their validity is untested by this proceeding. US Conec retains the right to assert the same patents against other parties.
