Patent Overview: US5479002A
Title: Bar code scanner with scanning beam and/or field of view adjustable about three mutually orthogonal axes.
Patent number: US5479002A. Application number: US08/366,383. Inventors: Frederic Heiman, Joseph Katz, Boris Metlitsky, Mark Krichever. Original/current assignee listed: Symbol Technologies LLC.
Key dates (as listed): Priority date 1988-05-11 (claimed from US07/193,265); filing date 1994-12-29; publication/grant date 1995-12-26; anticipated expiration 2012-12-26. Legal status: Expired – Lifetime.
Purpose and plain-language scope (per supplied text): The patent concerns a bar code scanner in which the scanning beam and/or the field of view can be adjusted about three mutually orthogonal axes. Prior-art keywords supplied include light, scanning, scan head, directing, and exit port. Classifications place it in optical/moving-beam bar code reading (e.g., G06K7/10554 moving beam scanning; G06K7/10603 basic scanning using moving elements; G06K7/10633 oscillation; G06K7/10881 hand-held scanner constructional details). The excerpt does not include the claims, detailed description, or drawings, so the precise claimed structure, axis-adjustment mechanism, and any limitations cannot be stated from this material alone. Related family members listed include US5144120A and US5191197A (earlier priority documents).
What the excerpt does not establish:
- The actual wording or scope of any claim (no claims text supplied).
- The specific mechanism(s) by which three-axis adjustment is achieved.
- Embodiments, components, or figures.
- Any prior-art analysis, validity, infringement, or litigation outcomes.

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.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
