998 F.3d 190
5th Cir.2021Background
- UAS (United Allergy Services) and AAAPC provided in-office allergy testing that disrupted referrals to allergists; Quest Diagnostics and Phadia allegedly coordinated to suppress that competition.
- Plaintiffs allege Quest shared UAS’s confidential client list with Phadia in February 2012 and that Quest and Phadia distributed false "talking points," relied on an OIG opinion, and targeted providers to induce them to stop using UAS.
- Plaintiffs filed an antitrust suit in 2014 against other actors; they learned of Quest’s role only after discovery in May 2016 and then sued Quest on December 28, 2017.
- The district court dismissed all claims under Rule 12(b)(6) as time-barred (antitrust claims: 4-year statute; trade-secret: 3-year; torts/conspiracy: 2-year) and denied leave to amend.
- The Fifth Circuit (Stewart, J.) affirmed in part and reversed/remanded in part: it reversed dismissal of federal and Texas antitrust claims and the trade-secret claim, and affirmed dismissal of civil-conspiracy and tortious-interference claims and the denial of leave to amend.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Timeliness of federal and Texas antitrust claims (Sherman §§1–2; Tex. antitrust) | Alleged post-2013 overt acts (including Phadia’s May 2014 email and continuing outreach) restart the 4-year statute of limitations | Latest Quest overt act was Aug 2013 (lobbying); later effects were mere aftershocks or insufficiently specific to restart limitations | Reversed dismissal: allegations that a co-conspirator (Phadia) committed overt acts in May 2014 sufficiently alleged continuation of the conspiracy and can reset the limitations period |
| Misappropriation of trade secrets (client list) | Plaintiffs did not discover Quest’s sharing of the client list until May 2016; discovery rule tolls 3-year SOL | Misappropriation occurred Feb 2012; plaintiffs could have discovered it earlier through diligence, so claim is time-barred | Reversed dismissal: the client-list misappropriation is plausibly inherently undiscoverable and plaintiffs adequately alleged they could not have discovered it with reasonable diligence |
| Civil conspiracy (Texas) | Discovery rule/fraudulent concealment tolls 2-year SOL because Quest concealed its role | Injuries to business were discoverable; plaintiffs litigated related injuries in 2014 suit; no inherently undiscoverable injury shown | Affirmed dismissal: conspiracy-related injuries were discoverable (no inherently undiscoverable injury); plaintiffs failed to plead diligence or tolling |
| Tortious interference (existing and prospective business) | Discovery rule applies; lost revenue and prospective-business losses toll limitations | Lost-revenue injuries were discoverable; prospective-interference not adequately pleaded (no reasonable probability alleged) | Affirmed dismissal: lost-revenue claims are discoverable; prospective-interference claim fails for insufficient factual detail |
| Denial of leave to amend complaint (Rule 15) | Plaintiffs moved for leave shortly after dismissal and proffered additional evidence | District court: request unduly delayed (no amendment sought during 11 months motion-to-dismiss was pending) | Affirmed: district court did not abuse discretion in denying leave because of undue delay and lack of a proposed amended complaint |
