EP Family Corp. v. Office Kick: 22-Patent Standing Desk Suit Voluntarily Dismissed
EP Family Corp. filed a sweeping 22-patent infringement action against Office Kick, Inc. in the Central District of California, targeting nine Amazon product listings across the standing desk and ergonomic furniture space. The case closed in 87 days when EP Family voluntarily dismissed without prejudice before Office Kick had answered or moved for summary judgment.
A 22-patent broadside against a standing desk rival, dropped in 87 days
On 24 February 2025, EP Family, Corp. — represented by Wang IP Law Group PC — filed suit against Office Kick, Inc. in the Central District of California, asserting infringement of 22 US patents covering standing desk and ergonomic furniture technology. The complaint targeted nine specific Amazon product ASINs, suggesting a highly product-focused enforcement strategy aimed at Office Kick’s active e-commerce catalogue.
On 22 May 2025, EP Family voluntarily dismissed the case without prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Office Kick had not yet answered the complaint or filed a motion for summary judgment, EP Family was entitled to dismiss unilaterally as of right — no court order was required. A dismissal without prejudice means the claims are not extinguished and EP Family retains the ability to refile the same claims in future proceedings.
The 87-day resolution, before any defendant response was filed, is consistent with several scenarios: early licensing discussions, a strategic pause to reassess claim scope, or a decision to pursue alternative enforcement routes. The public record does not confirm whether a settlement or licensing arrangement was reached. The breadth of the patent portfolio asserted — 22 patents spanning multiple application families — suggests EP Family maintains a significant IP position in the ergonomic furniture segment regardless of this dismissal.

Voluntarily dismissed: what Rule 41 without prejudice means for both parties
Rule 41(a)(1)(A)(i): dismissal as of right, no court order needed
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice of dismissal before the opposing party serves an answer or a motion for summary judgment. That threshold had not been crossed here. This is the most procedurally simple exit available to a plaintiff — it requires no judicial approval and takes effect immediately upon filing.
Plaintiff-initiated procedural exitClaims survive: EP Family can refile these 22 patents against Office Kick
A dismissal without prejudice does not resolve the underlying infringement claims on the merits. EP Family retains the legal right to reassert any or all of the 22 patents against Office Kick in a future action, subject to applicable statutes of limitation. This is materially different from a dismissal with prejudice, which would bar refiling. The public record does not disclose whether a settlement or licence was agreed — that distinction is commercially significant but cannot be confirmed from available filings.
Refiling right preservedOffice Kick escapes this action — but faces residual IP exposure
Office Kick avoided any judgment, injunction, or cost award and was never required to file a formal response. However, the dismissal without prejudice provides no IP clearance. The nine Amazon ASINs identified in the complaint remain potentially infringing in EP Family’s view, and the 22-patent portfolio is still active and enforceable. Office Kick would be prudent to assess design-around options or seek a licensing resolution to reduce the risk of a refiled action.
No clearance grantedA 22-patent portfolio signals sustained enforcement pressure on standing desk rivals
EP Family’s willingness to assert 22 patents simultaneously across nine Amazon product listings reflects a broad, portfolio-based enforcement posture in the ergonomic furniture space. Competitors and e-commerce sellers in the standing desk category should note that voluntary dismissal without prejudice does not signal weakness in the underlying IP position. The scale of the portfolio asserted suggests EP Family is positioned for ongoing enforcement across the sector.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) expressly and confirms that Office Kick had not answered or moved for summary judgment — the precise procedural conditions entitling EP Family to dismiss as of right. The ‘without prejudice’ designation is legally operative: no claim is extinguished, no court has ruled on validity or infringement, and EP Family’s full enforcement rights against these ASINs and patents are preserved. For Office Kick, the absence of any court ruling means no collateral estoppel protection attaches.
US11134774B1 and 21 further patents — ergonomic standing desk systems
The 22 patents asserted span application families filed between 2017 and 2024, covering a broad range of structural and functional elements of height-adjustable standing desk systems. The portfolio includes patents directed at frame and leg assemblies, lift and drive mechanisms, surface and panel configurations, control interfaces, cable management, anti-collision safety systems, and ergonomic accessory integration. The consistent award of US patents with B1 publication codes indicates these were granted without prior publication — suggesting prosecution strategies oriented toward speed and competitive surprise.
A portfolio of 22 asserted patents in a single product category is commercially significant. It suggests EP Family has pursued a systematic prosecution strategy — potentially through continuations and continuations-in-part — designed to create overlapping claim coverage across the full standing desk product architecture. For competitors and Amazon sellers in the ergonomic furniture space, this depth means that designing around one patent family is unlikely to provide meaningful clearance. The targeting of specific Amazon ASINs further demonstrates that EP Family actively monitors the marketplace and is prepared to file enforcement actions against specific commercial products.
Should you run an FTO against EP Family’s standing desk patent portfolio?
Any company designing, importing, or selling height-adjustable standing desks or ergonomic workstation products in the US market should treat EP Family’s 22-patent portfolio as a material freedom-to-operate concern. The ASIN-specific targeting in this case demonstrates that EP Family monitors e-commerce platforms for infringing listings — making Amazon and direct-to-consumer sellers particularly exposed. An FTO analysis should map claim scope across all 22 asserted patents, not merely the lead patent.
PatSnap Eureka’s FTO Search Agent can systematically map claim-level exposure across EP Family’s full patent family, identify continuation relationships, and flag overlapping claims covering your specific product architecture. Eureka’s landscape tools can also surface the complete EP Family portfolio beyond these 22 asserted patents, identifying additional risks before you commercialise or expand a standing desk product line. Proactive FTO review is significantly less costly than defending a 22-patent infringement action.

What this case signals for the ergonomic furniture IP landscape
A 22-patent complaint targeting Amazon ASINs is a defined enforcement playbook — here is what standing desk competitors need to understand.
ASIN-targeted complaints are a precision enforcement tool in e-commerce IP
By naming specific Amazon ASINs rather than product lines, EP Family tied infringement allegations directly to live, revenue-generating listings. This approach creates immediate commercial pressure on the defendant and signals sophisticated enforcement strategy. Standing desk and ergonomic furniture sellers operating on Amazon should treat ASIN-specific complaints as a heightened risk indicator.
Voluntary dismissal without prejudice does not close the litigation chapter
The 22 patents remain in force and the dismissal imposes no restriction on refiling. For Office Kick, this outcome provides no legal clearance. For the wider market, it confirms that EP Family’s patent portfolio is actively weaponised. Companies in adjacent product categories should map their exposure to EP Family’s patent families before expanding into overlapping product lines.
EP v Office — key questions answered
EP Family Corp. asserted 22 US patents in case 2:25-cv-01568, including US11134774B1, US11470959B1, US11147366B1, US11944196B1, US12082695B1, US12082696B1, and 16 additional patents covering ergonomic standing desk frame structures, lift mechanisms, control interfaces, and workstation accessories.
The public record does not disclose the reason for the voluntary dismissal. The dismissal was filed under Rule 41(a)(1)(A)(i) before Office Kick answered, which is consistent with early licensing discussions, a strategic decision to reassess claims, or a negotiated resolution reached off the record. No settlement terms have been publicly disclosed.
A dismissal without prejudice means none of the 22 patent infringement claims were resolved on the merits. EP Family retains the right to refile the same claims against Office Kick in a future action. Office Kick received no legal clearance and no finding of non-infringement or invalidity. The nine Amazon ASINs identified in the complaint remain potentially at risk.
The complaint identified nine Amazon product listings by ASIN: B095W87Z6K, B0BPND59R6, B095W8MDZP, B0B8N6168T, B09M9LR6YV, B0BNG1RN9R, B0BHL5YB5K, B0B1VF2H2J, and B08MHTR2TF. These are consistent with standing desk and ergonomic workstation products sold through Amazon’s marketplace.
EP Family asserted 22 US patents in a single action, spanning application families filed between 2017 and 2024 and covering a wide range of standing desk components and functions. This breadth is consistent with a systematic continuation prosecution strategy designed to create layered IP coverage. The portfolio scale places EP Family among the more prolific patent holders in the ergonomic furniture segment.
