Title: Bone compression device and method

Patent number: US10932833B2

Application number: US16/164,899

Inventor: Matthew P. Gephart

Original assignee: Pioneer Surgical Technology Inc

Current assignee (as listed): RTI Surgical Inc; Paragon 28 Inc — the source notes the listed assignees "may be inaccurate" and that Google performed no analysis or warranty as to the list.

Key dates:

  • Priority date: 2015-03-03 (stated as an assumption, not a legal conclusion)
  • Filing date: 2018-10-19
  • Publication of US20190046247A1: 2019-02-14

  • Legal status: Active; adjusted expiration 2036-09-04 (legal status given as an assumption, not a legal conclusion)

Purpose and plain-language scope: The title identifies the subject matter as a bone compression device and associated method. The prior-art keywords supplied are "configuration," "bone," "receiving portions," "anchor receiving," and "bone anchor," indicating the device involves receiving portions configured to receive bone anchors. The classification A61B17/80 places it among cortical plates (bone plates) and instruments for holding, positioning, or compressing bones attached to cortical plates, and subclass A61B17/808 covers instruments for holding or positioning bone plates or adjusting screw-to-plate locking mechanisms. Related classifications include A61B17/17 (guides or aligning means for drills, mills, pins or wires) and A61B17/1728 (such guides for holes). In plain terms, the patent concerns a device for compressing bone, apparently using bone anchors and receiving portions.

What the excerpt does not establish: The supplied text contains no claims, no abstract, no detailed description, and no drawings content. It therefore does not establish the specific structure, dimensions, materials, or the number and wording of claims; nor does it establish the method steps. The classifications and keywords are indexing data, not claim language. No statement is made here about litigation, ownership transfers, validity, or prior art, per scope.

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.
