Tomtom, Inc. v. Adolph
790 F.3d 1315
Fed. Cir.2015Background
- The ’836 patent (Dr. Michael Adolph) claims a method that generates, stores, and continuously updates traveled-distance and section data from a mobile unit (e.g., GPS-equipped vehicle). Claim 1 is the only independent claim.
- TomTom PNDs collect GPS trail data (Cayman Data) and upload logs to servers where data are merged and processed; TomTom was accused of infringing the European counterpart of the ’836 patent.
- During prosecution Adolph distinguished prior art (Saito and Thad) by asserting his invention does not require an initial map/database and that it stores more than mere point coordinates (e.g., direction, contiguity, timing). Examiner ultimately allowed the claims.
- The district court construed four claim terms (preamble “generating and updating data for use in,” “destination tracking system of at least one mobile unit,” “node,” and “storage device”) and entered judgment of noninfringement based on those constructions. Adolph appealed.
- The Federal Circuit reviewed intrinsic evidence de novo (and extrinsic factual findings for clear error when present) and reversed the district court on multiple claim constructions, remanding for further proceedings.
Issues
| Issue | Plaintiff's Argument (Adolph) | Defendant's Argument (TomTom) | Held |
|---|---|---|---|
| Whether the preamble phrase "generating and updating data for use in" is a claim limitation | Preamble is non-limiting; it states purpose and the claim body is structurally complete | Preamble gives life to the claim and should be construed as limiting | Reversed district court: the generating language is non-limiting and does not require the data to be "used by" the mobile unit |
| Meaning/scope of "destination tracking system of at least one mobile unit" (prosecution disclaimer) | Adolph disclaimed that the system does not require an initial map/database | TomTom: Adolph disclaimed systems that contain initial map/databases; prosecution disclaimer narrows to systems lacking initial maps | Reversed in part: no clear and unambiguous disclaimer that the system does not contain initial maps; correct construction: does not require initial information relating to existing road networks |
| Construction of "node" | "Node" equals geographic locations collected at predetermined time intervals (plain meaning) | District court: restricted to intersections/origin/destination/points where direction changes beyond threshold | Reversed: "node" means a geographic location (plain and ordinary meaning); district court improperly narrowed term |
| Whether claim requires separate storage devices for traveled-distance data, section data, and section data file | Adolph: "the storage device" in claim 1 refers to the single storage device recited earlier; the claim doesn't require separate devices | TomTom/district court: specification describes separate storage units; therefore each data type must be stored in different devices | Reversed: claim language uses "the storage device" (the "at least one storage device") — does not require separate devices; cannot import embodiment limitation into claim language |
