Patent Overview — US 6047322 A
Title: Method and apparatus for quality of service management
Patent number: US6047322A (application US08/999,096)
Inventors: Aseem Vaid; Sanjay Sawhney; Anand K. Antur; Naveen S. Bisht
Original assignee: Ukiah Software Inc. Current assignee listed as Micro Focus Software Inc; JPMorgan Chase Bank NA also listed.
Key dates (as listed): Priority date 1997-05-27; filing date 1997-12-29; granted/publication date 2000-04-04; anticipated expiration 2017-12-29. Legal status: Expired – Lifetime.
Purpose and plain-language scope: The supplied text states that the invention "relates to communication or telecommunication" and provides "a technique, including a method and system, for monitoring and allocating bandwidth on a telecommunication network at a firewall access point." It is described as implementable on a wide area network such as the Internet, while noting broader applicability to local area networks, combinations of wide and local area networks, and the like. The excerpt frames the problem in terms of user experience—the time spent waiting for images, texts, and other data to transfer—and defines Quality of Service as "often measured by responsiveness... and by throughput of data across the Internet," with other aspects potentially application specific (e.g., jitter, quality of playback). Prior-art keywords listed include: network, quality, directory services, server, service. Classifications include H04L43/00 (monitoring/testing data switching networks), H04L41/0894 (policy-based network configuration management), H04L41/0896 (bandwidth/capacity management), and H04L47/20 (traffic policing), among others.

What the excerpt does not establish: The supplied text is explicitly marked as an excerpt with omitted portions. It does not include the claims, the detailed description of the preferred embodiments, the drawings, or the full abstract, so the precise claimed scope and the specific apparatus/method steps cannot be determined from this source alone. It also does not establish legal ownership outcomes, validity, enforceability, or the content or relevance of any prior art. Per instructions, no litigation, ownership-transfer, validity, or prior-art research has been performed, and no facts beyond the supplied text have been inferred.

PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
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
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.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
