Purpose and plain-language scope (as supported by the supplied text): The patent concerns spinal fusion. Its stated subject matter covers bi-directional fixating transvertebral body screws, plus posterior cervical and lumbar interarticulating joint "calibrated stapling devices" intended for spinal fusion. The classification listings place it within spinal prostheses/implantation tools (A61F2/4611), bone staples (A61B17/0642), and spinal fixators/vertebral-facet devices and tools (A61B17/70, A61B17/7064). Prior-art keywords given are: screw, internal screw, top portion, intervertebral cage, and screw guide, indicating the described devices involve screws, an internal screw and top portion, an intervertebral cage, and a screw guide. The record also notes a litigation flag for the worldwide family, without substance.
What the excerpt does not establish: The supplied text contains no claims, abstract, or detailed description, so the precise claimed scope cannot be stated here; no verbatim claim language is available in the excerpt. It does not establish legal status as a conclusion (the "Expired – Lifetime" designation is expressly an assumption, not a legal determination), inventorship accuracy beyond the listing, priority-date correctness, or the content of the listed related applications. It provides no litigation details.
