Purpose and plain-language scope
Based only on the supplied text, the patent concerns an "access control system and method for use by an access device." The listed prior-art keywords — processor, certificate, reservation, access, access device — indicate that the disclosed subject matter involves a processor-based access device that uses certificates and reservations in controlling access. The classification data supplied is consistent with access control combined with electric-vehicle charging infrastructure: entries include G07C9/00007 (access control), H04W12/08 (access security), and multiple B60L53 subclasses covering conductive charging, charging connectors, cables, charging columns, and charging stations without connection to power networks. No abstract, claims, or detailed description text is included in the supplied excerpt.
What the excerpt does not establish
The supplied text contains no claim language, no abstract, and no written description. It therefore does not establish: the specific limitations of any claim; how the processor, certificate, reservation, and access device interact; whether charging-station access is the actual claimed subject matter (the B60L classifications are suggestive only); the content or dates of any prior-art reference; or the validity, enforceability, or scope of any claim. It also does not describe embodiments, figures, or technical advantages.
The excerpt does list litigation entries and ownership/assignment records, but per the stated scope those are not analyzed here, and no conclusions about them should be drawn from this overview.

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.
