Atlas Ip, LLC v. Medtronic, Inc., 809 F.3d 599

Background

Atlas IP owns U.S. Patent No. 5,371,734, claiming a MAC protocol where a hub schedules repeating communication cycles with intervals for hub outbound and remotes inbound transmissions to save remote battery power.
Atlas sued Medtronic alleging certain medical devices infringe claim 21 (the sole claim at issue); Medtronic counterclaimed invalidity under §§ 102, 103, 112.
The Southern District of Florida had previously construed key claim terms in a related case; those constructions were applied here. The district court granted summary judgment of non-infringement (after reconsideration) and granted Atlas summary judgment rejecting Medtronic’s anticipation/obviousness challenges to claim 21.
On appeal Atlas challenged the non-infringement ruling; Medtronic cross-appealed the invalidity ruling. The Federal Circuit reviewed claim construction issues de novo and addressed jurisdictional finality under §1295(a)(1).
The court affirmed non-infringement (holding the hub must define and transmit start time and duration of cycles/intervals before remotes transmit) but reversed the district court’s construction that each cycle must include a remote transmission, vacating the no-invalidity summary judgment and remanding for further proceedings.

Issues

Issue	Atlas (Plaintiff) Argument	Medtronic (Defendant) Argument	Held
Does the "establishing" and "transmitting" language require the hub to define and send start time and duration of cycles/intervals in advance of remote transmissions?	"Establish" means merely "initiate"; hub need not define/transmit start and duration in advance.	Hub must send schedule before remotes transmit so remotes can power on/off as claimed.	Held for Medtronic: hub must define and transmit start time and duration of cycles/intervals before remotes begin transmitting; non-infringement affirmed because accused devices did not meet this.
Does clause [b] require that in each communication cycle at least one (or every) remote actually transmit a frame (i.e., that remotes do transmit during every cycle)?	Clause requires remotes to transmit in each cycle (district court adopted "at least one remote transmits" reading).	Clause permits intervals in which remotes are allowed to transmit but does not require that any remote actually transmit in every cycle.	Held for Medtronic: clause [b] only requires that cycles include intervals when remotes are allowed to transmit; it does not mandate that remotes actually transmit each cycle. No-invalidity summary judgment reversed and remanded.
Finality/jurisdiction: Is the district court judgment final for appeal given partial adjudication and consent dismissal without prejudice of remaining counterclaims?	(Atlas) Appealable final decision exists.	(Medtronic) Not disputed here; regional-circuit law might differ.	Held: Federal Circuit law applies for patent appeals; decision was final and appellate jurisdiction exists under 28 U.S.C. § 1295(a)(1).
Standard of review for claim construction and summary judgment?	Claim construction should favor patentee’s narrower reading.	Claim construction is reviewed de novo; summary judgment de novo.	Held: Review de novo; court applied ordinary-meaning/specification analysis per Phillips and related authorities.
