Shockwatch v. Wan-yo Enterprise: Impact Indicator Patent Case Dismissed After Settlement
Shockwatch, Inc. sued Wan-yo Enterprise Co., Ltd. in the Western District of Texas asserting US9423312B2 covering its Impact Indicator 2 product. The parties reported a settlement after 342 days, but never filed closing papers — prompting the court to dismiss all claims without prejudice.
Impact indicator patent clash ends in unreported settlement dismissal
Shockwatch, Inc., a company operating in the impact monitoring and shock detection technology space and holder of US9423312B2, filed a patent infringement action against Wan-yo Enterprise Co., Ltd. on November 29, 2023, in the Western District of Texas before Judge Kathleen Cardone. The asserted patent relates to the Impact Indicator 2, a device used to detect and record physical impacts during product handling and transit.
On October 18, 2024, the parties jointly notified the court that they had reached a settlement. The court set a deadline of October 31, 2024, for submission of final closing papers, warning that failure to comply would result in dismissal without prejudice. When no closing papers were filed, Judge Cardone dismissed all of Shockwatch’s claims without prejudice on November 5, 2024, and denied as moot both Wan-yo’s motion to set aside a clerk’s entry of default and Shockwatch’s amended motion for default judgment.
The 342-day duration and the procedural path — including a clerk’s entry of default against Wan-yo — suggest the defendant initially failed to respond, which typically signals a contested posture that later resolved through negotiation. The absence of final closing papers means the precise settlement terms remain entirely outside the public record, and the without-prejudice dismissal leaves open the theoretical possibility of refiling if the settlement was not in fact consummated.

Dismissed without prejudice: what the court’s order means for both parties
Court-ordered dismissal, not a stipulated one
Rather than a joint stipulation of dismissal, this case ended via a court order under the judge’s own procedural framework. After the parties missed the October 31 deadline for closing papers, Judge Cardone exercised judicial discretion to dismiss without prejudice, also mooting two pending substantive motions — including Shockwatch’s amended motion for default judgment.
Judicial dismissal without prejudiceWithout prejudice: claims survive in theory
A dismissal without prejudice does not extinguish Shockwatch’s underlying patent claims. The order expressly preserved the right of either party to move to reopen by December 6, 2024, if the settlement had not been consummated. Whether a final agreement was ultimately executed, and on what terms, is not reflected in the public court record.
Claims preserved; settlement undisclosedDefault entry against Wan-yo denied as moot
The case record included a clerk’s entry of default against Wan-yo and a pending amended motion by Shockwatch for default judgment with damages discovery. These procedural weapons were denied as moot upon dismissal, suggesting that Wan-yo had eventually engaged in the litigation and that the settlement discussions overtook the default posture before any judgment was entered.
Default motion mooted by settlementUndisclosed settlement leaves competitive landscape unclear
Because no final closing papers, consent judgment, or license agreement appear in the public record, the commercial resolution — whether a licensing arrangement, design-around commitment, or damages payment — is unknown. Competitors in the impact indicator and shock detection space cannot reliably infer whether US9423312B2 was licensed or whether Wan-yo altered its product offering as a condition of resolution.

Official order — verbatim text
The court’s dismissal order reflects a structured judicial mechanism rather than a party-driven resolution. Judge Cardone’s October 25 order conditioned dismissal on the parties’ failure to submit closing papers — making the November 5 dismissal automatic and procedural. The denial of both the default-related motions as moot confirms that no liability finding was made; US9423312B2 was never ruled upon on the merits. The without-prejudice qualifier preserves Shockwatch’s enforcement rights fully.
US9423312B2 — Impact Indicator 2 shock detection technology
US9423312B2 (application number US14/517892) protects technology underlying Shockwatch’s Impact Indicator 2 product — a device designed to detect, record, and visually indicate physical impacts or shocks sustained by goods during transit, warehousing, or handling. Impact indicators of this type are used across logistics, supply chain management, and sensitive equipment shipping to provide tamper-evident evidence of rough handling. The patent covers the specific mechanical or electronic architecture that enables reliable impact threshold detection.
For the supply chain monitoring sector, US9423312B2 represents a core product patent rather than a peripheral improvement. Shockwatch’s willingness to litigate against a foreign manufacturer — and to pursue default judgment — signals active enforcement intent. Competing manufacturers of shock indicators, impact labels, or transit monitoring devices selling into or importing into the US market face meaningful infringement risk if their products replicate the patented indicator architecture, regardless of country of manufacture.
Should you run an FTO analysis against US9423312B2?
Any company developing, importing, or distributing physical impact detection devices — including shock indicators, impact labels, tilt indicators, or transit monitoring tools — for the US market should assess freedom to operate against US9423312B2. This case demonstrates that Shockwatch actively monitors the market for competing products and is prepared to pursue litigation, including default proceedings, against manufacturers who do not engage early.
PatSnap Eureka’s FTO Search Agent can map the claim scope of US9423312B2 against your product architecture, flag design-around opportunities, and identify the prior art landscape that defines the patent’s boundaries. Given the without-prejudice dismissal here — meaning no claim construction ruling exists — conducting your own claim analysis is the only reliable way to assess current exposure before entering the US impact monitoring market.

What this case signals for the impact monitoring IP landscape
This dispute highlights the enforcement dynamics around impact detection patents and the leverage created by early default proceedings in Texas federal court.
Default entry is a meaningful tactical tool in import-related patent disputes
Wan-yo’s initial failure to respond resulted in a clerk’s entry of default — giving Shockwatch significant leverage. For patent holders pursuing foreign manufacturers, filing in a court with strong default procedures can accelerate settlement discussions considerably. The mooted default judgment motion likely catalysed the October 2024 settlement notification.
Without-prejudice dismissals preserve enforcement optionality
The court’s dismissal without prejudice means Shockwatch retains the right to refile US9423312B2 claims if the settlement unravels. Companies competing with Wan-yo in the impact indicator market should not treat this dismissal as a clearance event — the patent remains in force and the dispute has not been adjudicated on the merits.
Shockwatch v Wan-yo — key questions answered
Shockwatch filed a patent infringement claim against Wan-yo Enterprise in the Western District of Texas asserting US9423312B2 relating to Impact Indicator 2 technology. The parties reported a settlement in October 2024, but never filed closing papers. Judge Cardone dismissed all claims without prejudice on November 5, 2024, and denied pending default-related motions as moot.
A dismissal without prejudice means Shockwatch’s infringement claims under US9423312B2 were not decided on the merits and the patent remains enforceable. Shockwatch retains the right to refile. The court expressly preserved the right to move to reopen by December 6, 2024, if the settlement was not consummated. The dismissal should not be read as a finding in Wan-yo’s favour.
US9423312B2 (application no. US14/517892) is a US patent held by Shockwatch, Inc. covering technology related to its Impact Indicator 2 product — a device that detects and visually signals physical impacts sustained during shipping and handling. It is a product patent in the transit monitoring and supply chain protection technology space.
A clerk’s entry of default is recorded when a defendant fails to timely respond to a complaint. Wan-yo Enterprise’s initial non-response triggered this default. Shockwatch then filed an amended motion for default judgment and damages discovery. Both motions were ultimately denied as moot when the case was dismissed following the reported settlement, suggesting Wan-yo eventually engaged with the litigation before any judgment was entered.
Yes. The dismissal was without prejudice and no merits ruling was issued. The patent was never invalidated, and no claim construction order was entered. US9423312B2 remains in force and Shockwatch retains full enforcement rights against any party whose products are found to infringe its claims. Companies in the impact monitoring and transit protection space should treat the patent as actively enforceable.
