Patent Overview — US 9,485,478 B2
Title: Communication and monitoring system
Patent number / application: US 9,485,478 B2; application US 14/670,044; pre-grant publication US 2015/0222852 A1.
Inventor: Ronald Carter.
Assignee / owner of record (as listed): Original assignee EYETALK365 LLC; current assignee SB IP HOLDINGS LLC (Google notes the listed assignees may be inaccurate and that it has not analyzed or warranted them).
Key dates: Priority date listed as 2002-10-15 (Google labels this an assumption, not a legal conclusion). Filing date 2015-03-26. Publication date 2016-11-01. Legal status shown as "Expired – Lifetime," with anticipated expiration noted 2023-10-09.
Purpose / plain-language scope (from the supplied text only): The classification data indicate a closed-circuit television (CCTV) system for receiving images from a single remote source, specifically a "video door telephone," and an "individual registration on entry or exit" system with electronically operated locks and non-mechanical keys. The "prior art keywords" listing — entrance, video, peripheral device, camera, wireless — indicates the subject matter concerns a wireless camera and peripheral device used at an entrance. Beyond these classifications and keywords, the excerpt does not contain the abstract, claims, or detailed description, so no claim scope, element list, or specific functionality can be stated.

What the excerpt does not establish:
- The actual claims, abstract, or written description (omitted from the excerpt).
- The precise technical operation of the system, or what is novel/non-obvious.
- Whether the 2002-10-15 priority date is legally correct, or what earlier application (US 10/682,185) it derives from.
- The current owner's enforceable rights; the recorded assignments, licenses, and security interests in the text are not analyzed here.
- The outcome, merits, or relevance of any listed litigation.
- The accuracy of the "Expired – Lifetime" status, which Google itself flags as an assumption.

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.
