Crown Packaging Technology, Inc. v. Ball Metal Beverage Container Corp.
635 F.3d 1373
Fed. Cir.2011Background
- Patents '826 and '875 share a specification teaching metal-savings by increasing chuck-wall slope and limiting anti-peaking bead width.
- The district court granted Ball summary judgment invalidating claims for written description and for anticipation by Toyo Seikan.
- Disputed issue whether the specification supports driving the chuck inside vs outside the reinforcing bead.
- Claims include '826 product claims (claim 14) and '875 method claims (claims 50 and 52); both address metal savings and bead considerations.
- Court reverses on written description, and remands for trial on anticipation; Crown awarded costs.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Written description sufficiency for the asserted claims | Crown contends the spec shows two separate solutions (sloped chuck wall and bead width) and supports claims | Ball argues Revolution Eyewear limits written description when problems are related; the spec must show same embodiment | Written description satisfied; claims valid against description grounds |
| Anticipation by Toyo disclosing an unseamed end | Crown contends Toyo does not disclose all limitations or inherent teachings to anticipate | Ball argues Toyo discloses embodiments that inherently anticipate the seamed end | Reversal in part; remand for trial to resolve credibility of expert testimony on anticipation |
| Obviousness not resolved on appeal | Court declines to decide; leaves for district court if raised on remand |
