Travel Sentry, Inc. v. Tropp
192 F. Supp. 3d 332
E.D.N.Y2016Background
- Tropp owns patents for a dual-access luggage-lock screening method; Travel Sentry licenses a trademark to manufacturers of such locks and provided TSA with master keys and a nonbinding MOU describing voluntary use.
- Travel Sentry sued Tropp (declaratory judgment) and Tropp counterclaimed; Tropp also sued multiple Travel Sentry licensees (Conair defendants) for infringement in a related action.
- This Court granted summary judgment to Travel Sentry in 2010 for no direct infringement because no single actor performed all method steps; indirect infringement was dismissed for lack of direct infringement.
- The Federal Circuit (relying on Akamai II) reversed on indirect infringement, prompting remand; subsequent Supreme Court and Federal Circuit en banc decisions in the Akamai/ Limelight line altered the law about divided performance of method claims.
- On remand after Akamai V (en banc), the court considered whether Travel Sentry’s relationship with the TSA created direct liability under the refined rule that a party may be liable if it conditions participation/benefit on performance and prescribes manner/timing of performance.
- The court found Travel Sentry’s MOU with the TSA was nonbinding: the TSA faced no obligation or consequence for noncompliance and retained independent control; no evidence Travel Sentry directed or masterminded TSA actions or formed a joint enterprise with TSA or Conair defendants.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Travel Sentry is directly liable for method-patent infringement where TSA performs steps | Tropp: Travel Sentry conditioned TSA participation/benefit on performing steps and influenced manner/timing (Akamai V theory) | Travel Sentry: TSA’s use was voluntary, nonbinding, and Travel Sentry did not control or direct TSA performance | Held: No direct infringement; Akamai V’s conditioning test inapplicable because TSA retained independent discretion and faced no consequences for failing to follow Travel Sentry guidance |
| Whether indirect infringement survives absent direct infringement | Tropp: Akamai variations allow indirect liability even if steps divided | Travel Sentry: After Akamai III and controlling precedent, indirect infringement requires direct infringement first | Held: Indirect-infringement theories denied in absence of direct infringement |
| Whether Travel Sentry is vicariously liable via joint enterprise with TSA or Conair defendants | Tropp: Parties formed joint enterprises linking all actors to attribute all steps | Travel Sentry: No agreement, no pecuniary community, no equal control; MOU was noncommittal | Held: No joint-enterprise liability; Tropp failed to prove the four required elements |
| Effect of Akamai V on prior summary-judgment ruling of no direct infringement | Tropp: Akamai V expands direct-infringement scope to capture Travel Sentry conduct | Travel Sentry: Akamai V does not disturb BMC/Muniauction test; facts here unlike Limelight | Held: Akamai V did not change outcome; prior summary judgment of no direct infringement stands, Tropp’s cross-motions denied |
