119 F.4th 984
Fed. Cir.2024Background
- UTTO Inc. owns US Patent No. 9,086,441 covering methods for detecting and identifying underground utility lines using location data and buffer zone concepts.
- UTTO sued Metrotech Corp. for patent infringement (related to the RTK-Pro locator device) and tortious interference with prospective economic advantage in the Northern District of California.
- The district court denied UTTO's motion for a preliminary injunction and subsequently dismissed UTTO’s claims through several rounds of amended complaints, with the final dismissal being with prejudice.
- The central patent dispute was over claim construction: specifically, whether “group of buried asset data points” means two or more, or could also mean one or more.
- The court dismissed the state-law tort claim due to UTTO’s failure to plausibly allege independently wrongful conduct by Metrotech.
- On appeal, the Federal Circuit reviewed de novo, vacated the patent claim dismissal for further claim construction proceedings, but affirmed the tort claim dismissal.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Claim construction at Rule 12(b)(6) stage | Claim construction at this early stage is improper | Claim construction is allowed at dismissal stage | No categorical bar; claim construction possible but fuller process needed |
| Meaning of "group of buried asset data points" | "Group" can mean one or more data points per asset | Ordinary meaning is two or more data points | Record insufficient; further proceedings needed on claim meaning |
| Sufficiency of patent infringement pleadings | Device meets claims even if using one data point | Their device operates only on single points, not groups | Dismissal vacated; sufficient allegations, further analysis warranted |
| Sufficiency of tortious interference pleadings | Metrotech unlawfully tied products and made fraudulent statements | No independently wrongful act and no market power in tying market | Dismissal affirmed; no plausible claim for independent wrongfulness |
