702 F.3d 1371
Fed. Cir.2012Background
- PTO conducted inter partes reexamination of Graphic's '639 patent, challenged by Zumbiel.
- Board rejected claims 1, 3-8, 10-14, 19-21, 32-41 as obvious; others (2, 9, 15-18, 22-31) remained patentable.
- Board held claims 1, 3-8, 10-13, 19-21 obvious over Ellis in view of German '718; claims 2, 9, 14, 32-39 not obvious.
- Graphic appealed; Zumbiel cross-appealed; court reviews de novo obviousness with substantial evidence for underlying facts.
- Representative claims at issue include 1, 2, and 13, concerning finger-flap location, tear-line structure, and basket functionality.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Obviousness of independent claims 1/13 over Ellis in view of German '718 | Graphic argues Ellis with German '718 teaches the claimed features; Board erred in finding nonobviousness. | Zumbiel argues the combination would be obvious to skilled artisan. | Claims 1 and 13 found obvious. |
| Nonobviousness of dependent claim 2 (finger-flap location) over Ellis in view of German '718 and Palmer | Graphic contends claim 2 is nonobvious due to finger-flap placement. | Zumbiel contends that Ellis, German '718, and Palmer render it obvious. | Claim 2 found nonobvious. |
| Whether preamble language limits the claims for purposes of patentability | Zumbiel argues preamble is non-limiting and should not constrain claim scope. | Graphic argues preamble supplies limiting antecedent basis to the claimed subject matter. | Preamble limited; terms are limitations in view of the body of the claims. |
| Overall scope of obviousness analysis applying KSR to a box-opening design | Zumbiel asserts the Board's analysis ignores common-sense and the KSR framework. | Graphic contends standard Board/legislative framework under KSR supports findings. | Board's ultimate obviousness determinations sustained (with dissent on approach not adopted here). |
