Advanced Steel Recovery, LLC v. X-Body Equipment, Inc.
808 F.3d 1313
Fed. Cir.2015Background
- Advanced Steel Recovery owns the ’950 patent, which covers a container packing system with a container packer driven along a base and a push blade actuated to discharge bulk material into a shipping container.
- The accused device, X-Body’s Acculoader, connects the container packer piston-and-cylinder unit to the container packer floor about 35% down from the proximal end, not at the edge.
- The district court construed 'proximate end' as the 'extreme or last part lengthwise' rather than a broad 'back half' interpretation, and found no literal infringement.
- The district court also held that the Acculoader could not infringe under the doctrine of equivalents because it did not meet the All-Elements Rule and there was no substantial equivalence for the proximate end limitation.
- Advanced Steel appealed, challenging the claim construction and seeking reversal on literal and equivalent infringement.
- The Ninth Circuit reviews claim construction de novo and infringement under the doctrine of equivalents as a factual question, applying the function-way-result test with proper evidence.
- The court ultimately affirmed summary judgment of no literal infringement and no infringement under the doctrine of equivalents.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| How should proximate end be construed? | proximate end is the back half opposite distal end | proximate end is the extreme or last part lengthwise | proximate end means extreme or last part lengthwise |
| Does Acculoader literal infringe the 'proximate end' limitation? | Acculoader attaches near the edge, potentially at proximate end | attachment is to the container packer floor, not at proximate end | no literal infringement |
| Is there infringement under the doctrine of equivalents for the proximate end? | should cover equivalent positioning of the connection | no substantial equivalence under function-way-result and All-Elements Rule | no infringement under the doctrine of equivalents |
| What is the proper standard of review and evidentiary approach for infringement? | claims and extrinsic evidence show equivalence | must show specific equivalence for each claim element | summary judgment proper; standard of review applied |
