85 F.4th 1148
Fed. Cir.2023Background
- PersonalWeb sued Amazon in 2011 over “True Name” patents; after claim construction it stipulated to dismissal with prejudice of claims against Amazon’s S3 product, producing a final judgment adverse to PersonalWeb.
- In 2018 PersonalWeb sued 85 Amazon customers (MDL) asserting the same patents against the same S3 technology; Amazon intervened and filed a declaratory judgment action; the MDL proceeded with Twitch as the representative customer case.
- The district court granted summary judgment of noninfringement as to Amazon S3 (Kessler/claim‑preclusion grounds) and later as to CloudFront; the court then awarded prevailing parties attorneys’ fees under 35 U.S.C. § 285, finding the case “exceptional.”
- The district court’s exceptionality finding rested on five principal factual/legal determinations: (1) S3‑related claims were objectively baseless (Kessler/claim preclusion); (2) PersonalWeb frequently changed infringement theories; (3) PersonalWeb unnecessarily prolonged litigation post‑claim construction; (4) unreasonable conduct regarding the customer cases (Twitch representation); and (5) submission of inaccurate declarations.
- The district court awarded roughly $5.19 million in attorneys’ fees; the Federal Circuit reviewed for abuse of discretion and affirmed the exceptional‑case finding and fee award; Judge Dyk dissented, arguing the Kessler issue was not objectively baseless and noting the Solicitor General’s later views.
Issues
| Issue | Plaintiff's Argument (PersonalWeb) | Defendant's Argument (Amazon/Twitch) | Held |
|---|---|---|---|
| Whether the case was “exceptional” under 35 U.S.C. § 285 | PersonalWeb argued its positions (including on Kessler application) were reasonable and part of good‑faith advocacy | Defendants argued the suit was baseless or unreasonably litigated (Kessler/claim preclusion, shifting theories, prolonging litigation, inaccurate declarations) | Affirmed: district court did not abuse discretion; totality of circumstances supported exceptionality |
| Whether Kessler / claim‑preclusion barred suits against customers after PersonalWeb’s dismissal with prejudice | PersonalWeb argued application of Kessler to a stipulated dismissal was unsettled and reasonably argued | Defendants argued the prior with‑prejudice dismissal gave the S3 product a limited trade right and barred customer suits | Held: Kessler/claim‑preclusion applied; S3 claims were objectively baseless |
| Whether shifting infringement theories and litigation conduct justified fees | PersonalWeb said shifting positions were zealous advocacy and responsive litigation | Defendants said frequent change of theories (S3 vs Ruby on Rails vs CloudFront) and reversing representations about Twitch undermined credibility and caused expense | Held: shifting theories and conduct supported exceptionality and fee allocation |
| Whether the fee award amount (specific categories) was improperly calculated | PersonalWeb challenged allocation of ~$1.95M as non‑exceptional and reductions as arbitrary | Defendants supported fee allocation tied to work provably caused by PersonalWeb’s misconduct; district court applied percentage reductions | Held: district court’s fee calculations and percentage reductions were a reasoned exercise of discretion and were affirmed |
