1:16-cv-03001
D. Colo.Dec 23, 2019Background
- Arason Enterprises sued CabinetBed alleging infringement of U.S. Patent No. 7,574,758 (the ’758 patent) covering a folding cabinet bed with a telescoping slide-out support platform; Arason earlier abandoned claims on U.S. Patent No. 6,851,139.
- The accused product (CabinetBed’s Standard Bed) has an extendable drawer that projects ~18 inches, a front wall extending ~30 inches, and an extension panel that reaches ~55 inches from the cabinet front.
- CabinetBed moved for summary judgment arguing (1) no literal infringement of Claim 1, (2) lack of priority, and (3) obviousness; Arason cross-moved for summary judgment on liability for Claim 1.
- The magistrate previously struck Arason’s contentions accusing CabinetBed’s Premium Bed product for failure to comply with local patent rules.
- The district court held that the accused bed does not literally infringe Claim 1 because the accused extendable drawer does not “support” the extension panel as a person of ordinary skill would understand that term; Arason’s doctrine-of-equivalents theory was deemed waived; Premium-Bed allegations dismissed without prejudice; remaining Arason claims dismissed with prejudice.
- The court dismissed CabinetBed’s counterclaim concerning the ’139 patent as moot and directed CabinetBed to state whether it will pursue remaining declaratory relief as to the ’758 patent.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Literal infringement of Claim 1 ("extendable structure supports front wall and extension panel") | Drawer plus front wall (via hinge) collectively support extension panel; therefore Claim 1 met | Drawer only extends ~18" and does not prop up or enable the extension panel to function as part of the sleeping platform when fully extended | No literal infringement; summary judgment for CabinetBed and Arason's SJ denied |
| Doctrine of equivalents (DOE) | DOE could be presented to the jury; not explicitly foreclosed in pleadings | DOE was not timely disclosed in infringement contentions; waived | DOE theory waived and not considered on summary judgment |
| Allegations vs. Premium Bed product | Premium-Bed allegations were not litigated on the merits; should be dismissed without prejudice | Defendant sought dismissal with prejudice of Premium-Bed-based claims | Premium-Bed allegations dismissed without prejudice; claims regarding the ’139 patent dismissed with prejudice (plaintiff stipulated) |
| Defendant's declaratory-counterclaims | N/A (Arason abandoned ’139 claims) | Defendant sought declaratory judgment of noninfringement as to both patents | Counterclaim on ’139 dismissed as moot; counterclaim as to Claim 1 of ’758 is moot; CabinetBed ordered to state whether it will pursue remaining issues on ’758 |
