Patent Overview: US8230497B2
Title: Method of identifying software vulnerabilities on a computer system
Patent number: US8230497B2 | Application: US10/287,125 | Publication: US20040088565A1
Assignee/owner: Original assignee Hewlett Packard Development Co LP; current assignee listed as Flash Uplink LLC. (Per instructions, ownership transfers are not analyzed here.)
Key dates: Priority/filing date 2002-11-04; published 2012-07-24; legal status listed Active, adjusted expiration 2031-09-24.
Purpose: To accurately determine whether a software vulnerability exists on a computer system by actively testing for it, rather than relying solely on a database matching software versions to known vulnerabilities. The patent notes conventional IP-address scanning can be inaccurate and slow, and remediation often involves manual steps.
Plain-language scope: A management system applies an "interrogation program" to software on a networked computer system. The interrogation program is code (possibly a URL or HTTP request, or an executable) designed to exploit a specific known vulnerability if present. If exploitation succeeds, the program generates management information identifying the affected computer system (e.g., its network/IP address) and sends it to the management system. Multiple interrogation programs can each target different vulnerabilities, and the program may also automatically remediate the vulnerability—sending a patch over the network—and report on remediation performed or still required. It may also identify viruses present, including their identification in the management information. In a network-wide version, a scanning system sends interrogation programs to many computer systems (possibly concurrently or across IP address ranges), and exploited vulnerabilities cause management information to be generated at the affected system and sent to the management system.
Classification: H04L63/1433 (vulnerability analysis).

Proceedings on file (0)
All PTAB activity →AIA trial proceedings (IPR / PGR / CBM) filed at the USPTO Patent Trial and Appeal Board against this patent. Sourced from the USPTO Open Data Portal and refreshed every six hours; each proceeding number deep-links to the PTAB E2E docket.
No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
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.
