1:15-cv-03702
N.D. Ill.Sep 1, 2017Background
- Shuffle Tech (with licensee Poydras and DigiDeal) developed the DigiShuffle; SHFL (later acquired by Bally/Scientific Games) owned extensive shuffler patents including the '982 and '935 patents derived from the Deckmate 1 design.
- SHFL sued DigiDeal in Nevada for infringement of the '982 and '935 patents after seeing the DigiShuffle at a trade show; litigation produced a set of documents ("shuffler art discs") containing alleged prior art (Nicoletti, Luciano, Roblejo prototypes and Block '044 patent).
- PTO proceedings: reexaminations rejected several claims based on Block and Roblejo references; SHFL amended/cancelled claims and ultimately obtained reexamination certificates for both patents.
- Plaintiffs (Shuffle Tech, Aces Up, Poydras) sued SHFL alleging (inter alia) a Walker Process / Walker Process–style antitrust claim: SHFL obtained patents by fraud on the PTO and enforced them in sham litigation to suppress competition in the shuffler market (Sherman Act §2 and Clayton Act §4/16 claims remain).
- District court in Nevada denied DigiDeal's motion for exceptional-case attorneys' fees (finding SHFL's suit was not objectively baseless); plaintiffs here are not parties to that Nevada suit but had contractual/licensing ties and participated in early defense.
- This opinion denies SHFL's summary judgment motion on the remaining antitrust/sham litigation and Walker Process fraud theories, finding genuine disputes of material fact as to SHFL's intent to deceive the PTO (especially concerning omission of the Block '044 patent) and rejecting issue-preclusion as to Walker Process theory.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether plaintiffs are precluded by issue preclusion from relitigating whether SHFL's suit against DigiDeal was a sham (objectively baseless) | Plaintiffs say they are not bound by the Nevada ruling because they were not adequately represented or in privity for the fee motion and they also assert a separate Walker Process fraud theory | SHFL says Nevada judges already decided objective baselessness against DigiDeal, and plaintiffs had a substantive legal relationship / effectively controlled the defense so should be precluded | Court: Issue preclusion applies only to the objectively baseless element (Nevada decided it) but does not preclude plaintiffs' Walker Process fraud theory; plaintiffs were not adequately represented at the time of the fee ruling so preclusion does not bar their sham-litigation theory fully. |
| Standard for proving intent to defraud the PTO for Walker Process claim | Plaintiffs rely on Federal Circuit Walker Process authority allowing intent to be inferred from circumstances and use expert proof (Therasense-era standards discussed) | SHFL urges application of Therasense clear-and-convincing, single-most-reasonable-inference standard and challenges experts | Court: Applies Walker Process standards used post-Therasense (requires clear and convincing independent evidence of deceptive intent); recognizes but does not definitively adopt Therasense's stricter phrasing; resolves intent disputes for summary judgment analysis. |
| Admissibility and scope of plaintiffs' expert (Armitage) testimony on intent and prosecution practices | Plaintiffs offer Armitage to explain prosecution norms and support inferences of intent (coupled with technical expert Curley) | SHFL challenges hundreds of Armitage opinions as speculative, legal conclusions, or improper opinions on individual intent | Court: Admits Armitage on general prosecution practices and what reasonable counsels would do; excludes any opinion that directly opines that specific SHFL individuals "must have known" or that they actually intended to deceive. |
| Whether evidence suffices to survive summary judgment on fraudulent procurement and enforcement (Walker Process) | Plaintiffs point to omissions/selective disclosures (notably Block '044 and CARD-related materials), CARD litigation materials, reuse/selective submission of shuffler-art discs, and expert analyses showing overlap/materiality | SHFL contends lack of knowledge of specific references (Nicoletti, Luciano), cumulative/reference-not-material defenses, and that objective baselessness already rejected by Nevada | Court: Denies summary judgment. Genuine disputes exist: insufficient evidence for Nicoletti/Luciano knowledge during '982 prosecution, but sufficient circumstantial evidence for knowing omission of Block '044 during '982 prosecution and for omission/selective disclosure of CARD-related materials during '935 prosecution and the later reexaminations to permit a jury to infer fraudulent intent. |
