BTL Industries v. Exquisite Depot: EMSculpt Patent Dismissed Without Prejudice
BTL Industries, holder of US10478634B2 covering electromagnetic muscle-sculpting technology, sued Exquisite Depot LLC and individual defendant Omry Gottlib in New Jersey federal court over six competing body-contouring devices. The case closed in just 143 days — not on the merits, but because BTL failed to seek default judgment within the court’s deadline.
Procedural default ends BTL’s EMSculpt infringement action early
BTL Industries, Inc., a medical device company and holder of US10478634B2, filed suit on September 24, 2024, in the U.S. District Court for the District of New Jersey against Exquisite Depot LLC and Omry Gottlib. The complaint alleged infringement of a patent covering electromagnetic body-contouring and muscle-stimulation technology — the core IP behind the commercially prominent EMSculpt NEO device category — through six Exquisite-branded consumer-grade devices sold under the ED-WLEMT and related product lines.
The case closed on February 14, 2025, when the court dismissed the action without prejudice against all defendants. The dismissal was not on the merits: the court’s order cites BTL’s failure to request entry of default and default judgment within the timeframe set by a January 29, 2025 order (docket entry 14). The without-prejudice designation means BTL retains the legal right to refile the same claims, subject to any applicable statutes of limitations.
At 143 days, the resolution timeline is unusually short and is entirely attributable to a procedural lapse rather than any substantive adjudication of the patent’s validity or scope. The public record does not reveal why BTL failed to comply with the court’s default-judgment deadline — possibilities include settlement discussions, licensing negotiations, or an internal decision to reassess litigation strategy. No defendant counsel of record appears in the docket, which is consistent with the defendants having never formally appeared, making the default-judgment pathway the expected route before BTL’s non-compliance.

Dismissed without prejudice: what the court’s order means for both sides
Court dismissed for failure to pursue default judgment in time
When defendants fail to appear or respond, plaintiffs typically move for entry of default and then default judgment. Here, the court set a deadline via its January 29, 2025 order; BTL did not comply. Under Federal Rule of Civil Procedure 41, courts may dismiss for failure to prosecute. The without-prejudice designation means no final judgment on the merits was entered — the claim is not extinguished.
Dismissed — no merits rulingBTL retains the right to refile — but the clock keeps running
A without-prejudice dismissal leaves BTL’s infringement claims legally intact. BTL can refile in New Jersey or another competent district, provided the relevant statute of limitations (typically six years for patent damages under 35 U.S.C. § 286) has not expired. However, repeated procedural missteps could affect judicial credibility in a refiled action. Whether BTL intends to refile or has reached an informal resolution with the defendants is not disclosed in the public record.
Refile option preservedExquisite Depot escapes judgment — but infringement exposure persists
Neither Exquisite Depot LLC nor Omry Gottlib obtained a ruling that their products do not infringe US10478634B2. The dismissal without prejudice provides no legal shield against a future action. Continued sale of the six accused devices remains potentially infringing. Defendants who never appeared carry particular vulnerability: if BTL refiles and they again default, the court may move more quickly toward a default judgment.
No infringement immunity grantedUnresolved IP creates ongoing risk for consumer EMSculpt device sellers
US10478634B2 remains enforceable and unchallenged on the merits. Any manufacturer or distributor of consumer-grade electromagnetic body-sculpting devices operating in BTL’s patent space should treat this dismissal as a procedural pause, not a green light. BTL’s core patent has not been invalidated, limited, or licensed by this action. The consumer aesthetics device market — particularly low-cost EMSculpt alternatives — remains exposed to future enforcement activity.

Official order — verbatim text
The court’s dismissal order is narrowly procedural: BTL failed to request default and default judgment within the timeframe set by the January 29, 2025 order. No finding was made regarding infringement or validity of US10478634B2. The without-prejudice language is significant — it distinguishes this outcome from a dismissal with prejudice, which would bar refiling. For Exquisite Depot and Gottlib, the order provides temporary relief but no legal immunity from future claims under the same patent.
US10478634B2 — Electromagnetic Body Sculpting and Muscle Stimulation
US10478634B2, filed under application number US16/034793, protects technology in the field of high-intensity focused electromagnetic (HIFEM) body sculpting — the core scientific basis of BTL’s commercially marketed EMSculpt and EMSculpt NEO product lines. The patent covers apparatus and methods for inducing supramaximal muscle contractions via electromagnetic fields, enabling non-invasive muscle building and fat reduction. This category of medical aesthetics technology has seen rapid market growth and significant IP competition.
For BTL, US10478634B2 represents a strategic cornerstone patent in the non-invasive body contouring market — a sector projected to grow substantially through the mid-2020s. Consumer-grade alternatives from smaller brands such as Exquisite Depot directly threaten the premium positioning of BTL’s clinical devices. Competitors developing or distributing HIFEM or EMS-based body-sculpting devices — particularly those featuring multiple applicator handles or combined fat-freezing and electromagnetic modalities — face elevated infringement risk under this patent’s claims.
Should you run an FTO against US10478634B2 before launching an EMS sculpting device?
Any company developing, importing, or distributing electromagnetic muscle-stimulation or body-contouring devices in the U.S. market should treat US10478634B2 as a high-priority FTO target. BTL has demonstrated willingness to enforce this patent at the district court level. The accused products in this case — ranging from single-handle EMS machines to four-handle EMSculpt-style systems — represent the broad commercial range that BTL considers within its enforcement perimeter.

What this case signals for the body-sculpting device IP landscape
A procedural dismissal leaves BTL’s core electromagnetic sculpting patent fully intact — and the competitive threat unresolved.
Without-prejudice dismissal is not a clearance certificate for competing devices
US10478634B2 was never adjudicated on validity or infringement. Competitors and distributors of consumer EMSculpt-style products cannot treat this outcome as evidence that BTL’s patent is weak or unenforceable. The legal risk for makers of similar electromagnetic muscle-stimulation devices remains unchanged from the day suit was filed.
BTL’s enforcement posture against low-cost alternatives remains active
BTL filing suit against a small LLC and an individual defendant suggests it is actively monitoring consumer-market substitutes for its premium EMSculpt NEO line. Even where enforcement lapses procedurally, the filing itself signals willingness to litigate. Companies distributing or manufacturing competing devices should monitor BTL’s patent portfolio and any new filings.
BTL v EXQUISITE — key questions answered
The court dismissed the action without prejudice on February 14, 2025, because BTL Industries failed to move for entry of default and default judgment within the timeframe set by the court’s January 29, 2025 order. No merits determination was made. The without-prejudice designation means BTL retains the right to refile the infringement claim.
US10478634B2 covers apparatus and methods for non-invasive electromagnetic body contouring and muscle stimulation — the technological basis for BTL’s EMSculpt NEO platform. The patent is relevant to any device using high-intensity focused electromagnetic fields (HIFEM) or EMS technology to induce muscle contractions for aesthetic body sculpting purposes, including consumer-grade multi-handle devices.
The dismissal without prejudice does not constitute a finding that Exquisite Depot’s products are non-infringing. US10478634B2 remains valid and enforceable. BTL could refile against Exquisite Depot at any time within the applicable limitations period. Continued sale of the accused devices carries ongoing infringement exposure.
Naming an individual alongside the LLC suggests BTL sought to establish personal liability — a common strategy in cases involving small corporate entities that may be judgment-proof. This signals that patent holders in the consumer device space are increasingly targeting individuals in addition to business entities to ensure collectability of any damages award.
A dismissal without prejudice does not extinguish the underlying cause of action, so BTL could seek damages in a refiled action. However, under 35 U.S.C. § 286, patent damages are limited to the six years preceding the complaint. The period during which this case was pending does not toll the limitations clock, so BTL must refile promptly to preserve its full damages window.
