What it concerns

Compositions and cross-linked polymer networks including at least one soft fluoropolymer segment and at least one hard fluorinated polymer segment which are covalently bonded through a linking moiety are provided. Methods of making the compositions and networks, and devices that incorporate them are also provided. The polymer networks may be designed to exhibit specific mechanical or physical properties which are tunable through by synthetic techniques including variation in the number and/or identity of the hard fluorinated polymer segments and soft fluoropolymer segments.

The abstract as published by the patent office, from US20250026885A1. It describes the invention; it is not a statement of what is protected.

Protection themes

  • Interface and electrodes

    Electrodes and arrays

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B2562/028, A61B2562/04, A61B5/268, A61N1/05, C08G65/33355). The claims define what a patent protects, and they are not read here.

Why it matters

Interface and electrodes
Everything downstream works with what the contacts pick up. Their number, size and distance from the neurons set the ceiling on the signal. The problem behind it: more contacts, closer to neurons, that still record after years in tissue that reacts to them.

Why the layer matters to the field, not a judgement of this filing. A patent family shows that protection was sought. It does not show that the technology was built, is used in a product, or works in people. The whole stack

The family

One invention, published 6 times in 6 offices. Each publication opens in Espacenet.

Dates as the offices published them. Office records are in the offices' own words and are a selection: refusals, lapses and withdrawals, and records that name an owner. Each concerns one member of the family, not the family as a whole, and another member in the same office may stand. Whether a patent is in force today is not assessed.
