Patent Overview — US 8,726,379 B1
Title: Systems and methods for dynamic protection from electronic attacks
Patent number: US 8,726,379 B1 (application US 13/550,354)
Assignee: Original assignee Norse Corp. Per the listed current assignee, Norse Networks Inc. A 2012-10-01 assignment to Norse Corporation and a 2016-06-29 assignment to Norse Networks, Inc. appear in the record; a 2015-01-16 security interest to Venture Lending & Leasing VII, Inc. is also listed. Google notes assignee listings "may be inaccurate" and that legal status is an assumption, not a legal conclusion.
Inventors: Tommy Stiansen; Samuel M. Glines; Sheldon H. Foss, Jr.
Dates: Priority date 2011-07-15; filing date 2012-07-16; publication/grant 2014-05-13. Status: Expired – Fee Related, adjusted expiration 2032-08-22. Later applications claim priority to this one (US 14/224,822 and US 14/842,603).
Purpose and plain-language scope: The patent concerns protecting a computer network against electronic attacks. The listed prior-art keywords — computer, risk, address, computer network, network — indicate a risk-based approach operating on network addresses. Classifications place it in network security for detecting/protecting against malicious traffic (H04L63/14, H04L63/1441), including by monitoring network traffic (H04L63/1408) and using deception such as honeypots/honeynets (H04L63/1491), plus supporting lawful interception (H04L63/30). Combined with the title's "dynamic protection," the scope centers on adaptively defending a network by assessing risk associated with addresses and traffic, with possible deceptive countermeasures. No detailed claim language is reproduced in the excerpt, so specific claim limitations cannot be stated.

What the excerpt does not establish: The excerpt omits the abstract, full description, and all claims, so the precise claimed invention, claim count, and claim scope are not established. It also provides only classification-level and keyword-level indications of subject matter; these are metadata, not claim text. Dates and legal status are expressly labeled assumptions by the source. Nothing here establishes validity, enforceability, litigation history, or how the cited classifications map to specific claim elements.

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.
