Boston Inventions v. Apple: Infringement Action Dismissed With Prejudice in 90 Days
Boston Inventions, LLC brought a patent infringement claim against Apple, Inc. in the District of Massachusetts, asserting US9721712B2 against the Apple Watch Leather Link and Fine Woven Magnetic Link. The parties jointly stipulated to dismiss all claims with prejudice under FRCP 41(a)(1)(A)(ii) just 90 days after filing, with each side bearing its own costs.
A swift joint exit: Apple Watch band patent case ends at 90 days
Boston Inventions, LLC filed suit against Apple, Inc. on February 1, 2024 in the U.S. District Court for the District of Massachusetts (Case No. 1:24-cv-10275), before Judge Richard G. Stearns. The complaint alleged infringement of US9721712B2, a patent covering wearable band attachment technology, specifically targeting Apple’s Watch Leather Link and Fine Woven Magnetic Link accessories. Lambert Shortell & Connaughton represented the plaintiff; Apple was defended by DLA Piper US LLP.
On May 1, 2024 — just 90 days after filing — both parties filed a joint stipulation of dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), terminating all claims with prejudice. Each party agreed to bear its own attorneys’ fees, costs, and expenses. The with-prejudice designation permanently extinguishes Boston Inventions’ ability to reassert these specific claims against Apple, and the mutual cost-bearing arrangement suggests no monetary payment was publicly disclosed as part of the resolution.
The 90-day resolution is notably fast for patent litigation of this type, which typically extends well beyond a year in district court. The speed and the with-prejudice joint stipulation — before any claim construction or substantive rulings — is consistent with a confidential settlement, a licensing resolution, or an early agreement to stand down. The public record does not disclose the commercial terms, if any, that accompanied the dismissal, leaving the underlying economics of the resolution undisclosed.
Filing to Dismissed with Prejudice in 90 days
Well below the median district court patent case — resolved before any substantive motion practice
Dismissed with prejudice: what the joint stipulation means for both parties
FRCP 41(a)(1)(A)(ii) joint stipulation ends the case permanently
Under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), parties may voluntarily dismiss an action by filing a signed stipulation. When the stipulation specifies dismissal ‘with prejudice,’ the plaintiff permanently relinquishes the right to bring the same claims against the same defendant again. No court order is required — the filing itself terminates the case. This mechanism is the most common vehicle for patent cases that resolve by agreement before substantive adjudication.
FRCP 41(a)(1)(A)(ii) — voluntary, bilateralBoston Inventions permanently surrenders its claims against Apple
The with-prejudice designation means Boston Inventions cannot refile suit against Apple on US9721712B2 for the accused products — the Apple Watch Leather Link and Fine Woven Magnetic Link. This is a hard bar, not a procedural pause. Whether Boston Inventions received any value in exchange — a license fee, design change commitment, or other consideration — is not reflected in the public record. The patent itself remains in force and could potentially be asserted against other defendants.
Claims extinguished against AppleApple secures permanent dismissal with no public adverse finding
Apple exits the case without any court ruling on infringement, validity, or damages. The with-prejudice dismissal eliminates future litigation risk from Boston Inventions on these claims. The mutual cost-bearing provision means Apple did not recover its legal fees despite the dismissal, which is typical in agreed resolutions and does not imply fault. Apple’s product lines — the Leather Link and Fine Woven Magnetic Link — face no injunctive or monetary liability on the public record.
No adverse ruling — risk eliminatedRapid resolution suggests commercial logic outweighed continued litigation
A 90-day dismissal with prejudice before any substantive rulings is consistent with a confidential licensing agreement or an early commercial resolution. For the wearables accessories sector, the case signals that US9721712B2 was asserted against high-profile Apple Watch products but did not proceed to contested adjudication. Competitors and designers working on wearable band attachment mechanisms should note that the patent survives and could be asserted against other parties.

Official order — verbatim text
The joint stipulation language is precise and consequential: ‘dismissed with prejudice’ under FRCP 41(a)(1)(A)(ii) means the termination was bilateral, consensual, and permanent. No court adjudicated the merits of infringement or validity. The ‘each party bearing its own attorneys’ fees, costs, and expenses’ clause is a standard mutual waiver in agreed resolutions, and its inclusion suggests neither side sought — or could extract — fee-shifting under 35 U.S.C. § 285. The public record is silent on whether any commercial consideration passed between the parties.
US9721712B2 — wearable band attachment mechanism technology
US9721712B2 (application number US15/060014) covers technology in the wearable band attachment space, directed at coupling or fastening mechanisms used in wrist-worn devices such as smartwatch bands. The patent’s issuance as a B2 grant indicates it survived examination with allowed claims. It was asserted specifically against Apple’s Leather Link and Fine Woven Magnetic Link products, suggesting its claims may read on magnetic or mechanical band-attachment interfaces used in premium wearable accessories.
The assertion of this patent against two of Apple’s flagship Watch band products — the Leather Link and Fine Woven Magnetic Link — signals commercial relevance in the premium wearables accessories market. With the Apple Watch holding significant global market share, any patent with plausible claims over Watch band attachment technology carries meaningful licensing leverage. Competitors producing similar magnetic-link or leather-strap wearable bands should treat this patent as a live enforcement risk, particularly given that the case resolved without invalidation.
Should you run an FTO analysis against US9721712B2?
Any company designing, manufacturing, or distributing wearable band attachment mechanisms — particularly magnetic-link or leather-strap bands for smartwatches — should assess exposure to US9721712B2. The patent was asserted against two Apple Watch band products and survived litigation without any invalidity ruling. Product teams developing wrist-worn device accessories with quick-release, magnetic, or woven attachment systems are the primary audience for this FTO review.

What this case signals for the wearables accessories IP landscape
A fast, bilateral exit in a high-profile wearables case raises questions about the enforceability of band-attachment patents and Apple’s litigation risk posture.
With-prejudice joint dismissals signal commercial resolution, not capitulation
When both parties jointly stipulate to dismiss with prejudice before any ruling, it typically reflects a negotiated outcome — not a unilateral concession. IP teams should note that the with-prejudice bar protects Apple from re-litigation, while the mutual cost-bearing clause suggests parity in the agreed terms. The underlying deal, if any, remains confidential.
US9721712B2 remains enforceable against other wearable band manufacturers
The dismissal extinguishes claims against Apple specifically but does not invalidate or limit the patent. Boston Inventions retains the right to assert US9721712B2 against other companies producing wearable band attachment products. R&D teams developing similar accessories should conduct a freedom-to-operate review against this patent before product launch.
Boston v Apple — key questions answered
The case was dismissed with prejudice by joint stipulation on May 1, 2024, under FRCP 41(a)(1)(A)(ii). Both parties agreed to bear their own attorneys’ fees and costs. No court ruling on infringement or patent validity was issued. The dismissal permanently bars Boston Inventions from reasserting these claims against Apple.
Boston Inventions asserted US9721712B2, a patent covering wearable band attachment technology (application US15/060014), against Apple’s Watch Leather Link and Fine Woven Magnetic Link accessories. The case was filed in the U.S. District Court for the District of Massachusetts on February 1, 2024.
Dismissal with prejudice extinguishes Boston Inventions’ right to sue Apple again on these specific claims, but the patent itself remains valid and enforceable. Boston Inventions could assert US9721712B2 against other defendants making similar wearable band attachment products. The dismissal does not constitute a court finding on patent validity or infringement.
The 90-day resolution before any substantive court rulings is consistent with a confidential settlement or licensing arrangement reached early in litigation. This pattern — joint stipulation with prejudice and mutual cost-bearing — is typical when parties reach a commercial agreement without needing judicial resolution. The public record does not disclose specific terms or any financial consideration exchanged.
Boston Inventions was represented by Brendan M. Shortell of Lambert Shortell & Connaughton. Apple was represented by a DLA Piper US LLP team including Claire E. Schuster, Mary Catherine Dahl, Michael G. Strapp, and Safraz W. Ishmael. The case was assigned to Judge Richard G. Stearns in the District of Massachusetts.
