Classifications place it as a spinal fusion cage (A61F2/4455), substantially parallelepipedal cages including wedge-shaped parallelepipeds (A61F2/447; A61F2002/30261; A61F2002/30266), spinal prostheses and insertion/extraction tools (A61F2/4611), and adjustable angular orientation (A61F2002/30538). Terms appearing in the description include anchoring, bone, fusion, lordosis, ligament, titanium, ferrotitanium, and stainless steel.

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.
