Patent Overview — US 10,639,827 B2
Title: Eyelet for biomedical electrode and process for production thereof
Patent number: US 10,639,827 B2 (application US 16/063,397; also published as US 2018/0370088 A1)
Inventors: Cameron E. Derry; John P. Tryphonopoulos
Original assignee: 3M Innovative Properties Company. Current assignee listed as Solventum Intellectual Properties Co.
Key dates: Priority date 2015-12-22; filing date 2016-11-29; publication of the granted patent 2020-05-05; anticipated expiration 2036-11-29. Legal status listed as Active.
Purpose and plain-language scope (based on the supplied text):
The patent concerns an eyelet used in a biomedical electrode and a process for making it. From the classification data, the subject matter sits at the intersection of two fields: (1) compression moulding of plastics in continuous/indefinite-length form using rollers, including rollers with specific surface features such as cavities for forming distinct products, and (2) biomedical electrodes, particularly adhesive skin electrodes containing silver/silver chloride, conductive gels or pastes, or conductive polymers, and the snap or button fasteners used to connect lead wires to such electrodes.
The "prior art keywords" listed — film, eyelet, eyelets, conductive material, web — indicate that the disclosed eyelet and its production process involve a film and a conductive material handled as a web. The patent's stated aim is an eyelet for a biomedical electrode plus a method of producing it, with the moulding/roller classifications suggesting a continuous, roller-based manufacturing approach. The grant and reassignment entries, and the current Active status, are as recorded in the source.

What the excerpt does not establish: The supplied text contains no abstract, claims, or detailed description, so the specific structural features of the eyelet, the exact process steps, materials, and the precise scope of the claims cannot be determined here. The legal-status, assignee, and priority-date entries are expressly noted in the source as assumptions, not legal conclusions. This overview also does not address validity, prior art, litigation, or the details of the 2024 assignment.

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.
