Patent Overview — US 10,123,831 B2

Title: Bone compression device and method
Inventor: Matthew P. Gephart
Original Assignee: Pioneer Surgical Technology, Inc. (later recorded assignees include RTI Surgical, Inc. and Paragon 28, Inc.)
Application No.: US 15/058,695 | Publication: US 2016/0256203 A1
Priority Date: 2015-03-03 | Filing Date: 2016-03-02 | Grant Date: 2018-11-13
Legal Status: Active; adjusted expiration listed as 2036-10-21 (a stated assumption, not a legal conclusion)

Purpose and Plain-Language Scope: The supplied text describes the invention as relating to a "bone compression device and method," classified under A61B17/80 (cortical bone plates) and A61B17/808 (instruments for holding or positioning bone plates). The classification places the subject matter in the field of internal bone fixation, specifically cortical plates used to compress bones, and instruments for holding, positioning, or adjusting screw-to-plate locking mechanisms. Related classifications include drill/wire guides for bone plate holes (A61B17/1728).

Plain-language scope: Based on the excerpt alone, the patent concerns a device and method for compressing bone — likely a bone plate system and associated instrumentation — used in osteosynthesis to hold bone fragments or segments together. The prior-art keywords listed ("bone plate," "bone," "manipulators," "bones," "end portions") suggest claims or disclosure involving a bone plate with end portions and manipulators for applying compression.

What the excerpt does not establish:

  • The specific claims, claim language, or independent/dependent claim structure
  • The precise mechanical configuration, components, or method steps of the device
  • Any embodiments, figures, or detailed description (the text notes omitted content)
  • Whether the device is indicated for a particular anatomical site (e.g., foot, ankle, hand)
  • The relationship between this patent and related applications (US 16/164,899; US 17/158,628) beyond recorded priority events
  • Any legal conclusions regarding validity, enforceability, or claim scope

Per instructions, no litigation, ownership-transfer analysis, validity, or prior-art research was performed.

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.
