Mr. Peanut's Pet Products v. Apollo Investment: Voluntarily Dismissed in 18 Days
Mr. Peanut's Pet Products, LLC filed a patent infringement action against Apollo Investment Holding Co. LLC in the Southern District of Florida, asserting US9163370B2 across a range of pet products including leashes, restraints, clothing, toys, and pooper scoopers. The case was voluntarily dismissed with prejudice just 18 days after filing, with each party bearing its own fees and costs.
A swift exit: pet products patent suit dismissed in under three weeks
On 30 March 2026, Mr. Peanut's Pet Products, LLC filed Case No. 0:26-cv-60892 in the U.S. District Court for the Southern District of Florida before Judge David S. Leibowitz, asserting infringement of US9163370B2 against Apollo Investment Holding Co. LLC. The asserted patent relates to pet products including leashes and restraints, clothing, pet toys, and pet pooper scoopers. Plaintiff was represented by Lawrence Allen Caplan of Lawrence A. Caplan, P.A.; no defendant counsel appears in the available record.
The recorded basis of termination is 'Voluntary dismissal.' The docket order — filed on Plaintiff's Voluntary Dismissal with Prejudice [ECF No. 10] — states that the action is dismissed with prejudice, with each party to bear its own attorneys' fees and costs. The specific terms underlying the dismissal are not disclosed in the available record.
The 18-day duration from filing to closure is notably brief, suggesting the matter was resolved or abandoned before any substantive litigation activity. What prompted the voluntary dismissal — whether a pre-suit resolution, a licensing arrangement, or a strategic decision not to proceed — is not reflected in the public record.

US9163370B2 — pet leashes, restraints, and accessory products
Any company manufacturing, importing, or selling pet leashes, restraints, clothing, toys, or pooper scoopers in the US market should assess freedom to operate against US9163370B2. The patent has been actively asserted in litigation, and this case produced no invalidity finding or claim construction that could inform a clearance position. The risk is live.
Official order — verbatim text
The court's order dismisses the action on the plaintiff's own motion, with each party directed to bear its own attorneys' fees and costs. No infringement finding, claim construction, or validity ruling was issued. The order's fee allocation — each side bearing its own costs — is consistent with a negotiated or uncontested exit rather than a contested merits decision.
Voluntarily dismissed: what the resolution means for both parties
Voluntary dismissal: plaintiff-initiated end to proceedings
A voluntary dismissal is filed at the plaintiff's own election, ending the case without a merits ruling from the court. Here, the recorded basis of termination is 'Voluntary dismissal.' The docket order states the dismissal is with prejudice — meaning the plaintiff cannot re-file the same claims against the same defendant. Each party bears its own attorneys' fees and costs per the court's order.
Plaintiff-initiated dismissalPrejudice distinction matters for future enforcement
The basis of termination recorded is 'Voluntary dismissal,' without specifying with or without prejudice. The verbatim docket order, however, states dismissal 'with prejudice,' which would bar the plaintiff from bringing the same patent claims against the same defendant again. These two characterisations are presented as-is; the public record does not disclose the underlying reason for either characterisation. Practitioners should consult the docket directly to assess preclusive effect.
Preclusive effect unresolved in recordPlaintiff exits litigation early with no merits ruling
Mr. Peanut's Pet Products secured no court finding on infringement or validity of US9163370B2. The patent itself remains in force, unaffected by this dismissal. The plaintiff retains the right to assert the patent against other parties, though the docket order's with-prejudice language — if controlling — would foreclose re-filing against Apollo Investment specifically. The specific terms underlying the dismissal are not disclosed in the available record.
Patent survives; no merits adjudicationSwift resolution leaves competitive landscape unchanged
Because the case ended without any claim construction, infringement finding, or validity ruling, no public precedent was set regarding the scope of US9163370B2. Competitors in the pet products sector — particularly those making leashes, restraints, or related accessories — should note the patent remains active and enforceable. Third parties have no court record to rely on for FTO assessments; independent analysis of US9163370B2 is warranted.

Forward-looking patent intelligence derived from the Mr. Peanut's Pet Products v. Apollo Investment action and the technology landscape around US9163370B2.
Mr. Peanut's Pet Products: enforcement portfolio and filing activity
Mr. Peanut's Pet Products has demonstrated willingness to assert US9163370B2 offensively. R&D and IP teams in the pet accessories sector should map the plaintiff's full patent portfolio — including any continuation or divisional applications — to understand the breadth of potential claims covering leashes, restraints, and related products.
Active enforcement postureFiling trends in pet leash, restraint, and accessory patents
US9163370B2 sits within a broader landscape of pet product innovation. Understanding the density of patent filings around leash mechanisms, restraint systems, and pet clothing can help product teams identify white space and avoid inadvertent infringement as competition in the pet accessories market intensifies.

Apollo Investment Holding Co. LLC was named as a defendant but no patent filings or IP portfolio details appear in the available case record. Monitoring whether Apollo holds or acquires patents in adjacent pet product categories — and how it positions defensively — is relevant for competitors and potential market entrants.

The broad product scope of US9163370B2 — covering leashes, restraints, clothing, toys, and waste collection tools — suggests potential white space in adjacent pet product innovations not captured by existing claims. R&D teams can use claim mapping to identify design-around opportunities and areas with lower patent density for new product development.

What this case signals for the pet products IP landscape
An 18-day lifespan with no defendant counsel on record raises questions about pre-suit dynamics and enforcement strategy around pet product patents.
US9163370B2 remains active and unvalidated by courts
No court has ruled on the validity or scope of US9163370B2. For any company making or selling pet leashes, restraints, clothing, toys, or pooper scoopers, the patent presents an unresolved risk. A freedom-to-operate analysis against this patent is advisable before launching competing products in these categories.
Ultra-short case duration signals pre-litigation resolution or strategic withdrawal
Cases resolved within 18 days of filing — before substantive proceedings begin — typically reflect either a pre-suit agreement reached quickly after filing or a decision not to proceed. No defendant counsel appears in the available record, which is consistent with an early, informal resolution, though the specific terms are not disclosed publicly.
Mr. v Apollo — key questions answered
The case was voluntarily dismissed. The recorded basis of termination is 'Voluntary dismissal.' The docket order, filed on Plaintiff's Voluntary Dismissal with Prejudice [ECF No. 10], states the action is dismissed with prejudice, with each party bearing its own attorneys' fees and costs. The specific terms underlying the dismissal are not disclosed in the available record.
The sole patent asserted was US9163370B2 (application number US14/090475), covering pet products including pet leashes and restraints, clothing, pet toys, and pet pooper scoopers. No claim construction or validity ruling was issued during this case.
No. The case was voluntarily dismissed before any substantive merits ruling. No finding of validity, invalidity, infringement, or non-infringement was issued by the court. The patent remains in force and its claims remain uncontested by this litigation.
The available public record does not disclose the reason for the rapid resolution. The 18-day duration and the absence of any defendant counsel on the docket suggest the matter was resolved or abandoned very early, but the specific circumstances are not reflected in the court record.
If the dismissal with prejudice stated in the docket order is controlling, Mr. Peanut's Pet Products would be barred from re-filing the same patent claims against Apollo Investment Holding Co. LLC. The patent itself, however, remains active and enforceable against third parties. Practitioners should review the docket directly to assess the precise preclusive effect.
