Patent Overview — US 7,243,945 B2

Title: "Weight measuring systems and methods for vehicles"

Patent number: US 7,243,945 B2 (application US 10/733,957; pre-grant publication US 2004/0129478 A1)

Inventors: David S. Breed, Wilbur E. DuVall, Jeffrey L. Morin

Original assignee: Automotive Technologies International Inc. (later listed current assignee: American Vehicular Sciences LLC)

Key dates (as listed, assumptions not legal conclusions):

  • Priority date: 1992-05-05; application filed 2003-12-11; granted/published 2007-07-17.
  • Legal status listed as "Expired – Fee Related," adjusted expiration 2013-12-23.

Stated subject matter and purpose (per supplied text): The patent concerns weight measuring systems and methods for vehicles. It sits within a family claiming priority from numerous earlier US applications (e.g., US 08/474,783; 08/474,786; and many others into 2003), and it is itself a parent priority for many later filings. The listed prior-art keywords are occupant, vehicle, seat, pat, and sensor. Accordingly, the plain-language scope implied by the supplied text is a vehicle-based weight-measurement arrangement, plainly associated with sensing an occupant's weight in a seat—used, in this family's context, for vehicle occupant sensing and related safety/diagnostic functions. However, the excerpt contains only the bibliographic face of the patent; it includes no claims and no specification text.

What the supplied excerpt does not establish:

  • It does not establish the actual claims, their scope, or any specific claim limitations.
  • It does not establish how the weight measurement is performed, what structures or algorithms are used, or the precise technical purpose beyond the title.
  • It does not establish the content, dates, or applicability of any prior art, nor any conclusion on validity or infringement.
  • It does not establish the accuracy of the assignee listings, the priority chain, or the legal status; the source expressly labels status and assignee data as assumptions, not legal conclusions.

Litigation, ownership transfers, validity, and prior art were not researched, consistent with instructions.

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
