Purpose and plain-language scope: The title indicates a system and method using artificial intelligence to guide surgery while it is underway ("intra-operative"). The listed classifications place it in computer-aided surgery and surgical navigation (A61B34/20), surgical planning/modelling (A61B34/10), surgical robots (A61B34/30), image-guided drill/pin/wire alignment including along or parallel to the femoral neck axis (A61B17/1703, A61B17/1721), surgical cameras (A61B90/361), machine learning and neural networks—including convolutional, supervised, and reinforcement learning (G06N20/00, G06N3/04, G06N3/08, G06N3/09, G06N3/092)—image feature extraction and graphical representations (G06V10/42, G06V10/426), and healthcare informatics for image handling and mechanical/invasive therapies such as surgery (G16H30/40, G16H20/40). The listed prior-art keywords are "image, operative, intra, anatomy, subject."
What the excerpt does not establish: The supplied text is truncated and includes only bibliographic data, classifications, and event listings—no claims, abstract, or detailed description. It therefore does not establish the actual claimed scope, specific components, algorithms, or embodiments; nor whether the listed classifications accurately reflect the claims. All dates, statuses, and assignee entries are expressly flagged in the source as assumptions, not legal conclusions. No litigation, validity, or prior-art analysis is included here.

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.
