Patent Overview — US9185324B2 ("Sourcing EPG data")
Bibliographic data (as supplied)
- Title: Sourcing EPG data
- Patent number: US9185324B2; Application No. US13/970,234; Pre-grant publication US20140053207A1
- Inventors: Mikhail Shoykher, John S. Visosky, Ron Cassar, Robert Csiki
- Original assignee: Flextronics AP LLC; current assignee listed as Multimedia Technologies Pte Ltd
- Priority date: 2012‑08‑17; filed: 2013‑08‑19; granted/published: 2015‑11‑10
- Anticipated expiration listed: 2033‑08‑19; legal status listed as active (noted by the source as an assumption, not a legal conclusion)
Purpose and plain-language scope
The title and the source's "prior art keywords" (EPG, source, information, intelligent, EPG information) indicate the patent concerns sourcing electronic program guide (EPG) data—that is, obtaining program-listing information from one or more sources, with an "intelligent" EPG information element. Classification data in the excerpt places it in television/EPG-adjacent areas alongside user-interface categories (e.g., H04N5/4401 and various G06F3/048 GUI interaction classes), which is consistent with an EPG sourced and presented through a user interface. Beyond this, the excerpt provides no claim language, no abstract, and no description text.
Prosecution/family notes given
The source lists a related later application (US14/821,365, leading to US9819986B2) and another (US15/801,601, leading to US10419805B2), and indicates the family has associated litigation data.
What the excerpt does not establish
- The actual scope of any claim (independent or dependent), and therefore what is legally protected.
- The specific technical problem, embodiments, or how EPG data is sourced, validated, or selected among sources.
- Whether the listed related applications share the same specification or claims.
- Any litigation details, ownership-transfer substance, validity, or prior-art content; these are outside this overview and were not researched.
- Whether the listed assignee and status entries are accurate as a legal matter (the source itself disclaims this).

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.
