27 F.4th 587
8th Cir.2022Background
- In 2015 Wildhawk purchased Brava Roof Tile’s assets and received an exclusive, perpetual license to Brava I.P.’s patents and "Know-How" for the manufacture and sale of "Roofing Shingles," with a broadly worded definition of Licensed Products and an automatic license to any Improvements.
- A proposed written ROFR (right of first refusal) for new products was removed from the signed license (to satisfy Wildhawk’s lender), but the parties acknowledge a contemporaneous oral "handshake" ROFR and later executed an NDA that recited a ROFR on new R&D developments.
- Boor and Edson (sellers) stayed on as paid consultants; Wildhawk negotiated repeatedly to buy the new "Natura" designs and offered royalty structures but never closed a deal.
- In 2019 Boor and Edson formed Paragon and, in 2020, began producing Natura shingles using processes/materials derived from the Brava Know-How. Wildhawk sued and the district court granted a preliminary injunction barring Paragon from manufacturing/selling the products.
- The Eighth Circuit held that, although the license’s language likely covered the Natura products, Wildhawk’s post-contract conduct (NDA, prolonged negotiations, silence, and delay) gave rise to equitable estoppel and that Wildhawk failed to show irreparable harm; the court reversed and vacated the preliminary injunction.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Scope of license / breach | Wildhawk: license language is broad and covers Natura and any Improvements derived from Know-How | Paragon: license limited to the four original products; Natura falls outside because not covered by patents/raw-material manufacturing language | Court: contract language is broad; license likely covers Natura, and factual findings supporting likely breach were not clearly erroneous |
| Effect of NDA / parol evidence | Wildhawk: NDA did not change license and does not trump written license | Paragon: NDA and handshake ROFR show contemporaneous agreement limiting Wildhawk’s rights | Court: NDA is extrinsic evidence but does not contradict integrated license; parol evidence cannot be used to alter written terms, so NDA cannot revive a contractual term that contradicts the license (but see estoppel ruling) |
| Equitable estoppel defense | Wildhawk: contractual rights are clear; no basis to estop | Paragon: Wildhawk’s conduct (NDA, negotiations, silence, offers) induced reliance and prejudice—clear, convincing evidence of estoppel | Court: accepted estoppel — Wildhawk’s representations and conduct induced reliance; estoppel makes Wildhawk unlikely to prevail on the merits |
| Irreparable harm / preliminary injunction | Wildhawk: Paragon’s sales will cause loss of customers, market share, and goodwill that money cannot fully remedy | Paragon: harms are economic and compensable; Wildhawk delayed and lacked diligence | Court: economic losses are compensable; delay undercuts claim of irreparable harm; Wildhawk failed to prove imminent, non-compensable injury |
