946 F.3d 1367
Fed. Cir.2020Background
- Two patents at issue: ARM’s U.S. Patent No. 8,720,320 (the ’320 patent) and Eko’s U.S. Patent No. 8,707,855 (the ’855 patent); parallel ITC proceedings had earlier produced an ITC limited exclusion order against Eko on some ’320 claims.
- ARM sued / counterclaimed in district court: Eko sought declaratory judgment of noninfringement and invalidity (obviousness) of claims 8 and 19 of the ’320 patent; ARM counterclaimed infringement.
- District court construed key terms (e.g., “brewing chamber,” “passageway”), granted summary judgment of noninfringement on the ’320 claims, and a jury later found claims 8 and 19 of the ’320 patent invalid as obvious; the court also awarded attorney’s fees to Eko (noninfringement and exceptional conduct under §285).
- For the ’855 patent, ARM stipulated to infringement under the court’s claim construction; jury awarded damages but found no willful infringement and the court denied enhanced damages.
- Both parties appealed/cross-appealed. The Federal Circuit affirmed: invalidity of the asserted ’320 claims and the fee awards; affirmed infringement of the ’855 claim; affirmed the no-willfulness outcome (finding the jury instruction problematic in parts but, taken as a whole, legally adequate).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Meaning of “brewing chamber” in ’320 | ARM: must be sealed / fully enclosed | Eko: ordinary meaning — a compartment where brewing occurs; not necessarily sealed | Court: affirmed district court — no sealed/fully-enclosed requirement |
| Prior art disclosure & obviousness of ’320 claims (Nordskog/Beaulieu/Sylvan) | ARM: cited references do not disclose sealing engagement; verdict unsupported | Eko: Beaulieu (and combinations) disclose sealing engagement; renders claims obvious | Court: substantial evidence supports jury finding (Beaulieu discloses sealing engagement); obviousness affirmed |
| Construction of “passageway” and summary judgment of noninfringement | ARM: district court improperly read “narrow/length” limits and excluded embodiments (broad mesh) | Eko: district court correctly held a passageway excludes a receptacle that relies on a broad thin mesh; noninfringement proper | Court: even if first phrase debatable, second phrase (excluding receptacle-with-mesh) sustained; summary judgment and fees for noninfringement affirmed |
| Attorney’s fees for obviousness (§285 exceptional case) | ARM: denial of summary judgment meant position was reasonable; fees inappropriate | Eko: ARM litigated unreasonably and conduct was exceptional; fees justified | Court: district court considered totality, denial of summary judgment not dispositive, fee award not an abuse of discretion |
| Construction of claim 8 of ’855 (whether preamble requires brewer) | ARM: claim requires a single-serve brewer; selling device alone does not infringe | Eko: preamble is a reference point, not a limiting element | Court: claim 8 does not require the brewer itself; infringement stands (ARM stipulated) |
| Jury instruction on willfulness / enhanced damages | Eko: instruction invited jury to decide punishment/egregiousness; misstated law post-Halo | ARM: instruction sufficiently described deliberate conduct | Held: instruction contained erroneous phrases, but taken as a whole it properly allowed jury to find deliberate/intentional infringement; no reversible error; no willfulness affirmed and enhanced damages properly left to the court |
