- Full Citation: US20170035443A1, Greatbatch Ltd., "Bi-directional reamer assembly"
- Publication Date: February 9, 2017
- Filing Date: August 7, 2015
- Brief Description: This patent application describes a bi-directional reamer assembly. A bi-directional reamer offers different functional aspects than a unidirectional one, but it is still a reamer assembly.
- Potential Anticipation (35 U.S.C. § 102): The "bi-directional reamer assembly" is highly relevant. It would be important to analyze if this prior art discloses a cutting rib with an arcuate portion, a wavy outer sharp edge, tunnels in a gap with a centralizer, and an inner edge configured to interlock with a second cutting rib, as claimed in US10631883. The bi-directional aspect itself might be a distinguishing feature from US10631883, but the core reaming mechanism could still anticipate elements.

- Publication Date: December 21, 2017
- Filing Date: June 14, 2016
- Assignee: Razor Medical Instruments LLC (same as a previous assignee for US10631883).
- Brief Description: This international publication describes a tool for cutting bone for surgical use, with the same assignee as US10631883 during an earlier assignment. This indicates a related body of work.
- Potential Anticipation (35 U.S.C. § 102): This is a very strong candidate for prior art due to the common assignee and the general subject matter. It is highly probable that this document discloses many, if not all, of the features of Claim 1 of US10631883. A direct comparison of the claims in WO2017218589A1 with Claim 1 of US10631883 would be crucial to assess anticipation. Given the common assignee and the proximity of filing dates to the priority date of US10631883 (September 21, 2017), it might even be considered prior art under 35 U.S.C. § 102(a)(2) if it was filed before the invention date of US10631883 and subsequently published.

General Considerations for Anticipation:

For any of the cited prior art to anticipate Claim 1 of US10631883 under 35 U.S.C. § 102, every element of Claim 1 must be disclosed, either explicitly or inherently, in a single prior art reference. This includes:

A cutting rib with an arcuate portion.
An outer sharp edge on the arcuate portion.
A centralizer configured to receive the cutting rib through a radial slot.
The radial slot forming a gap with the cutting rib.
The arcuate portion following a surface of the centralizer.
The outer sharp edge having a wavy profile.
The wavy profile forming a tunnel in the gap.
The outer sharp edge protruding outwardly from the surface of the centralizer.
The arcuate portion forming a window with an inner edge.
The inner edge configured to interlock with the arcuate portion of a second cutting rib to form a rib assembly.

The "wavy profile that forms a tunnel in the gap" and the "inner edge configured to interlock with the arcuate portion of a second cutting rib" appear to be key distinguishing features that would need careful review in each piece of prior art.
