Buckingham Mfg v. Bashlin Industries: Climbing Belt Patent Settled in 184 Days
Buckingham Manufacturing Co., Inc. brought a patent infringement action against competitor Bashlin Industries, Inc. in the Western District of Pennsylvania, asserting US11679303B1 over Bashlin’s 88FFX4D Flex-Fit Climbing Belt. The case resolved through mediation in just 184 days — a notably swift settlement for a first-instance patent dispute between two lineworker safety equipment rivals.
Rival lineworker belt makers resolve D-ring patent clash through mediation
On May 8, 2024, Buckingham Manufacturing Co., Inc. filed a patent infringement complaint against Bashlin Industries, Inc. in the U.S. District Court for the Western District of Pennsylvania before Judge Christy Criswell Wiegand. The asserted patent, US11679303B1, covers a body belt assembly incorporating a specific auxiliary D-piece and dual auxiliary D-ring configuration — key structural elements of personal protective equipment used by electrical utility lineworkers and climbers. The accused product was Bashlin’s 88FFX4D Flex-Fit Climbing Belt.
The case closed on November 8, 2024, after a mediator’s report advised the court that the parties had reached a resolution. Judge Wiegand entered an order for administrative closing, directing the parties to file a stipulation of dismissal or joint status report by December 7, 2024, while expressly retaining jurisdiction to enforce any settlement terms during finalization. The basis of termination is recorded as ‘Case Settled,’ though specific financial or licensing terms have not been disclosed in the public docket.
At 184 days from filing to closure, the resolution timeline is notably compressed for patent litigation of this type, suggesting either that mediation was initiated early or that commercial pressures — including potential disruption to Bashlin’s Flex-Fit product line — accelerated negotiations. What drove the precise settlement terms remains unknown from the public record, as does whether any ongoing licensing arrangement or design-around obligation was included. The swift conclusion may also reflect the relatively narrow and well-defined claim scope of US11679303B1, which could have quickly clarified each party’s exposure.

Case settled via mediation: what the resolution means for both parties
Mediation-driven administrative closing explained
When a mediator reports a case resolved, the court typically enters an administrative closing order rather than immediately dismissing. Judge Wiegand retained jurisdiction through the stipulation deadline, meaning the settlement is not yet formally terminated on the merits. The case closed operationally on 11/8/2024, but formal dismissal — and its preclusive effect — awaited the parties’ stipulation filing.
Stipulation of dismissal pendingWith or without prejudice? The public record is silent
The court order directs the parties to file a stipulation of dismissal but does not specify whether it will be with or without prejudice. A dismissal with prejudice bars Buckingham from re-asserting the same claims against Bashlin. Without prejudice would preserve that option. Because the settlement terms are confidential and the stipulation had not yet been filed as of the order date, the public record does not resolve this distinction. IP professionals should monitor the docket for the final stipulation.
Prejudice status undisclosedBuckingham secures settlement without full trial risk
By resolving through mediation, Buckingham avoided the cost and uncertainty of claim construction, summary judgment, and trial. A settlement at this stage — before any Markman ruling — means US11679303B1 was never judicially construed, leaving its claim scope intact and untested. Buckingham retains the ability to assert the patent against other parties, and the patent’s validity was not challenged on the public record in this proceeding.
Patent validity unchallengedBashlin avoids injunction risk but terms remain opaque
Settlement removes the immediate threat of an injunction that could have disrupted Bashlin’s 88FFX4D Flex-Fit Climbing Belt business. However, without public disclosure of the settlement terms, it is unclear whether Bashlin agreed to a license, a royalty obligation, or a product redesign. Competitors in the lineworker equipment space should note that US11679303B1 survived this litigation intact, with no adverse validity or non-infringement finding on record.

Official order — verbatim text
The court’s order is administrative in nature rather than a merits ruling. Judge Wiegand’s direction to close the case upon the mediator’s resolution report, while expressly retaining jurisdiction to enforce settlement terms, is standard practice in the Western District of Pennsylvania. The order does not adjudicate infringement or validity. The express retention of jurisdiction is significant: it means either party may return to court to compel compliance with settlement terms without filing a new action, which is a meaningful enforcement mechanism for Buckingham should Bashlin fail to honour any agreed obligations.
US11679303B1 — Body Belt Assembly with Auxiliary D-Ring Configuration
US11679303B1 protects a body belt assembly comprising a body portion, a belt strap with buckle, and a specifically configured auxiliary D-piece connected to the body surface and extending between defined first and second ends. The patent also covers first and second auxiliary D-ring elements as part of the assembly. Filed under application number US17/411422, the patent is designated as a utility patent and relates to personal protective equipment — specifically climbing belts used by electrical utility workers who ascend poles and structures. The B1 designation indicates the patent issued without any pre-grant publication.
In the lineworker safety equipment market, D-ring placement, geometry, and attachment methodology are commercially significant differentiators affecting worker safety ratings, regulatory compliance, and product certification. US11679303B1 appears to define a specific structural arrangement of auxiliary D-pieces that, if broadly construed, could cover a range of competing belt configurations beyond the accused 88FFX4D product. For manufacturers in this sector, the patent’s survival through litigation without any narrowing construction makes it a key IP risk to monitor. Any company developing or sourcing climbing belts with auxiliary attachment points should conduct a thorough claim-by-claim FTO analysis.
Should your climbing belt product be cleared against US11679303B1?
Any manufacturer, distributor, or OEM sourcing body belt assemblies with auxiliary D-ring configurations for the utility climbing or lineworker market should treat US11679303B1 as an active enforcement risk. The patent has now been litigated — and settled in the patent holder’s favour — without any judicial narrowing of its claims. Product teams developing new belt designs with auxiliary D-piece attachments, dual D-ring configurations, or similar structural elements should not assume a design is clear without a formal FTO analysis against the issued claims and any continuation applications.

What this case signals for the lineworker safety equipment IP landscape
A swift mediated settlement preserves Buckingham’s patent and sends a clear enforcement signal to the climbing belt sector.
US11679303B1 remains fully intact — no claim construction on record
Because the case settled before any Markman hearing or claim construction order, US11679303B1 has never been judicially interpreted. This preserves maximum claim breadth for Buckingham and means competitors cannot rely on any narrowing construction to design around the patent. Any company making climbing belts with auxiliary D-ring assemblies should treat this patent as broadly scoped until a court rules otherwise.
Early mediation suggests both parties recognized significant commercial exposure
Resolution in under six months — before substantive motion practice — typically signals that one or both parties assessed their litigation risk as high. For Bashlin, a core product line was at stake. For Buckingham, a favourable settlement early in proceedings avoids the possibility of an IPR petition or invalidity challenge that might have threatened the patent. The speed of resolution is consistent with a commercially pragmatic outcome for both sides.
Buckingham v Bashlin — key questions answered
Buckingham Manufacturing asserted US11679303B1, a patent covering a body belt assembly with an auxiliary D-piece and dual auxiliary D-ring configuration. The accused product was Bashlin’s 88FFX4D Flex-Fit Climbing Belt. The patent was filed under application number US17/411422.
The case was resolved through mediation and closed by administrative order on November 8, 2024, approximately 184 days after filing. Judge Wiegand ordered the parties to file a stipulation of dismissal by December 7, 2024. The specific terms of the settlement — including any licensing payments, royalties, or product modifications — are not disclosed in the public record.
No. The case settled before any claim construction, summary judgment, or trial. US11679303B1 was never judicially construed or subjected to a validity ruling in this proceeding. The patent’s validity was not challenged on the public record, meaning it remains unchallenged and fully enforceable as issued.
The 88FFX4D Flex-Fit Climbing Belt is a body belt product manufactured by Bashlin Industries for use by electrical utility lineworkers. Buckingham alleged that the product’s body portion, belt strap, buckle, and auxiliary D-piece and D-ring configuration infringed the structural claims of US11679303B1. The specific infringement theory was not publicly adjudicated due to settlement.
The case was filed in the U.S. District Court for the Western District of Pennsylvania and assigned to Judge Christy Criswell Wiegand under case number 2:24-cv-00691. The case was filed on May 8, 2024, and administratively closed on November 8, 2024, following a mediation report indicating resolution.
