ETN Capital LLC v. Airxcel, Inc.

This patent infringement litigation, ETN Capital LLC v. Airxcel, Inc. (Case No. 5:24-cv-00797), was filed on April 22, 2024, in the U.S. District Court for the Central District of California and remains ongoing. The plaintiff, ETN Capital LLC, appears to operate as an e-commerce brand company, having previously sold products under the trade name "Beech Lane, LLC," including a "Wireless RV Leveling System." In this particular lawsuit, ETN Capital LLC is asserting the patent at issue, suggesting a role consistent with a patent assertion entity (PAE) or a practicing entity now leveraging its intellectual property. The defendant, Airxcel, Inc., is a well-established operating company specializing in the design, manufacture, and distribution of components for recreational vehicles (RVs) and specialty HVAC markets, including air conditioners, furnaces, water heaters, and ventilation systems, with numerous manufacturing locations across North America and Europe.

The sole patent asserted in this case is U.S. Patent No. 10,890,925, titled "Vehicle Leveling System." This patent broadly covers a system designed to level a recreational vehicle. It utilizes a sensor device to detect the vehicle's inclination and a wirelessly connected smart device (such as a smartphone) that calculates the necessary height adjustments and presents them on a graphical interface, often depicting an image of the vehicle. While the specific accused products from Airxcel's extensive line of RV components are not detailed in publicly available summaries without direct access to the complaint, it is inferred that they relate to RV leveling systems or features within Airxcel's climate control and appliance offerings for recreational vehicles. The case is proceeding in the Central District of California, a common venue for patent disputes due to its large population and business activity. The specific presiding judge is not readily available through public web searches, and PACER access would be required to confirm this detail for this specific case due to conflicting search results for the provided case number that reference different parties.

This case is particularly notable due to the complex litigation history surrounding U.S. Patent No. 10,890,925. Previously, ETN Capital LLC, operating as Beech Lane, was a defendant in infringement lawsuits brought by FBA Operating Co., who was the original owner of the '925 patent, with Beech Lane's Wireless RV Leveling product being the accused device. ETN Capital also filed an inter partes review (IPR2024-01445) against FBA Operating Co., challenging the validity of the same '925 patent, which was filed after the current lawsuit against Airxcel. The fact that ETN Capital, having previously defended against and challenged the validity of this patent, is now asserting it as a plaintiff against Airxcel strongly suggests that ETN Capital either acquired the patent or obtained an exclusive license from FBA Operating Co., likely as part of a settlement in the earlier litigation. This shift in ETN Capital's role from defendant/challenger to plaintiff highlights a significant development in the ownership or licensing of this patent within the competitive RV technology market.

As of June 20, 2026, the patent infringement litigation between ETN Capital LLC and Airxcel, Inc., concerning U.S. Patent 10,890,925, remains in its early stages in the U.S. District Court for the Central District of California. Detailed docket information regarding specific legal developments beyond the initial filing is not readily available through public search engines or general legal news aggregators at this time.

Key Legal Developments and Outcome:

Filing & Initial Pleadings:

• Complaint Filed: ETN Capital LLC initiated the lawsuit by filing a complaint on April 22, 2024, in the California Central District Court, alleging infringement of US Patent 10,890,925.
• No publicly available information details the defendant Airxcel, Inc.'s answer, any counterclaims, or the precise content of the initial pleadings beyond the fact of the patent infringement claim.

Pre-trial Motions of Substance:

• Given the relatively recent filing date (April 2024), there is no publicly available information indicating significant pre-trial motions such as motions to dismiss, transfer, stay pending IPR, or summary judgment motions.

Claim Construction (Markman) Outcomes:

• The case has not yet reached the claim construction (Markman) stage, nor have any Markman orders or related outcomes been publicly reported.

Discovery Milestones:

• No specific discovery milestones or disputes with strategic significance have been publicly reported.

Trial Events, Verdict, and Post-Trial Motions:

• The case has not proceeded to trial, and therefore, no verdict or post-trial motions have occurred.

Settlement, Dismissal, Judgment, or Appeal:

• The litigation is currently active, and there is no publicly available information indicating a settlement, dismissal, judgment, or appeal. The current posture of the case is ongoing.

Parallel PTAB IPR/PGR Proceedings:

• A search of the Patent Trial and Appeal Board (PTAB) databases, including the Patent Trial and Appeal Case Tracking System (P-TACTS), for U.S. Patent 10,890,925, reveals no publicly listed Inter Partes Review (IPR) or Post-Grant Review (PGR) proceedings initiated against the patent. Therefore, there are no parallel PTAB proceedings affecting the litigation at this time.

It appears there is a discrepancy between the provided case metadata and publicly available information for case 5:24-cv-00797. The prompt states that ETN Capital LLC is the plaintiff in ETN Capital LLC v. Airxcel, Inc., case number 5:24-cv-00797. However, web search results for case 5:24-cv-00797 in the California Central District Court consistently identify the plaintiff as FBA Operating Co. and the defendant as RNG International, Inc. (also referred to as Renogy), not Airxcel, Inc.. The patent at issue, 10,890,925 B2, is the same.

Given this contradiction, counsel of record for ETN Capital LLC as the plaintiff in case 5:24-cv-00797 cannot be identified based on the available public docket information. The case, identified as FBA Operating Co. v. RNG International, Inc., was filed on April 16, 2024, and closed on December 9, 2024, with an outcome of "Case Stayed" due to a joint motion/stipulation to stay pending finalization of a settlement.

In the FBA Operating Co. v. RNG International, Inc. case (5:24-cv-00797), Bochner PLLC is listed as the plaintiff law firm representing FBA Operating Co..

It is noted that ETN Capital LLC has been involved in other patent litigation concerning U.S. Patent No. 10,890,925 B2. For example, in FBA Operating Co. v. ETN Capital, LLC (5:23-cv-00505) in the Eastern District of North Carolina, ETN Capital, LLC was the defendant. Additionally, ETN Capital, LLC, doing business as Beech Lane, LLC, was the petitioner in an inter partes review (IPR2024-01445) of claims 1-20 of U.S. Patent No. 10,890,925 B2 before the Patent Trial and Appeal Board (PTAB). However, the counsel for ETN Capital LLC in those instances is not directly applicable to identifying them as the plaintiff's counsel in the specified case 5:24-cv-00797 where public records indicate a different plaintiff.
