Patent Overview: US8360599B2
Title: Electric shock resistant L.E.D. based light
Patent number: US8360599B2
Application number: US12/126,579
Inventors: John Ivey; Dennis Siemiet
Original assignee: Ilumisys Inc (later assignment to Altair Engineering, Inc., then to Ilumisys, Inc.)
Priority/filing date: 2008-05-23
Publication date (grant): 2013-01-29
Legal status (as listed): Active; adjusted expiration 2028-09-02. Google notes the legal status is an assumption and not a legal conclusion.
Purpose and plain-language scope (from the supplied text):
The patent concerns an electric-shock-resistant light built around light-emitting diodes (LEDs). The recurring prior-art keywords in the supplied excerpt are "circuit board," "heat sink," "LED," "light," and "LEDs," indicating the disclosure centers on an LED light with a circuit board and a heat sink. Classification entries point to an LED-based light source configured as a retrofit for fixtures with two fittings (e.g., substitution of fluorescent tubes), with arrangements for coupling devices/connectors, safety devices structurally associated with lighting devices, and passive heat-sinking — including metal heat sinks and parallel planar fins oriented along the light-emitting axis. Optical arrangements, such as refractors forming part of the light source, are also classified. The title indicates the electric-shock-resistant aspect is a defining feature.

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.
