Luxer Corporation v. ButterflyMX, Inc.
1:24-cv-00602
| D. Del. | Feb 6, 2025Background
- Luxer Corporation alleged that ButterflyMX, Inc. infringed U.S. Patent No. 11,625,675, which covers a system for controlling access to a storage room using an electronic lock and credential authentication.
- Luxer’s system, the “Luxer Room,” allows recipients and couriers to access package storage rooms via access codes and records entry events.
- ButterflyMX launched a similar product, which Luxer claimed infringed their patent.
- ButterflyMX moved to dismiss the lawsuit under Rule 12(b)(6), arguing the patent is invalid under 35 U.S.C. § 101 as directed to an abstract idea.
- The court was tasked with analyzing whether the patent claims were patent-eligible, focusing on whether they were directed at an abstract idea and if they contained an “inventive concept.”
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Are the patent claims eligible under § 101? | Luxer argued the claims are for a tangible machine/system for automated access, improving the technology of package storage by allowing any size package. | ButterflyMX argued the claims only automate longstanding, abstract ideas of credential-based access via conventional technology. | The claims are directed to an abstract idea and are not patent-eligible. |
| Should Claim One be treated as representative of all claims for eligibility analysis? | Luxer did not meaningfully contest using Claim One as representative, focusing on similarities in arguments for all claims. | ButterflyMX argued all claims were essentially the same as Claim One and added nothing inventive. | Claim One is representative; analysis applies to all asserted claims. |
| Does the patent provide an inventive concept beyond an abstract idea? | Luxer argued the combination and arrangement of conventional components is novel, and that acceptance by the USPTO shows inventiveness. | ButterflyMX argued the components and operations (signals, locks, authentication) were routine and generic in the industry. | No inventive concept was found; use of generic components in conventional ways. |
| Should the court defer to the USPTO’s patent-eligibility determination? | Luxer argued the USPTO’s allowance shows eligibility. | ButterflyMX argued courts are not required to defer to the USPTO on eligibility. | Courts owe no deference to USPTO eligibility findings. |
