Patent number / application: US6084528A; application US08/780,023, filed 1996-12-20; granted and published 2000-07-04.
Priority: 1996-09-05, claimed from US08/706,579 (per the supplied record).
Inventors: Robert Beach, William X. Tracy, Thomas K. Roslak, John Klein.
Assignee: Symbol Technologies LLC (original and current assignee as listed by the source). The record also lists assignments to Symbol Technologies, Inc. (1996-12-20 and 1997-03-24), a JPMORGAN CHASE BANK security interest (2005-01-05) and release (2010-12-03), a Morgan Stanley Senior Funding security agreement (2014-10-31) and release (2015-08-17), and a Symbol Technologies, LLC change of name (2015-07-08). Legal status listed as "Expired – Lifetime"; anticipated expiration 2016-09-05.
Purpose (per the supplied text): The invention "relates generally to an improved portable data terminal and a system for communicating information over a wireless communication network using the portable terminal." Such terminal systems "may include integrated bar code readers which permit the collection, storage and distribution of a high volume of data without the need for extensive keypad data entry"; "provide full computing capabilities using standard PC architectures"; and "may also be provided with wireless communication radio systems such as Symbol Technologies, Inc. local area network radio system 'SPECTRUM24™,'" which "permits hand-held terminals to share and retrieve data in the proximity of local area networks with a central host."
Plain-language scope (as described): A portable terminal "having an integrated machine code reader and a radio" with "a graphical user interface such as a 'web browser,'" a display "for illustrating help and instructional files associated with a selected item identified with the machine code reader," and "a relatively simple microprocessor and system architecture while providing full graphics and audio support." The text also situates the invention relative to self-service scanning systems in Dutch Patent Application No. 9002296 and U.S. Pat. No. 5,468,942 to Oosterveen et al., where customers scan merchandise, maintain a purchase list in memory, download it via a communication port to a terminal dispenser, and print a ticket.

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

Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
