Federal Circuit Summary for Week Ending June 9, 2023
Medtronic, Inc. v. Teleflex Innovations S.A.R.L., No. 2021-2357, 2021-2360, 2021-2364 (June 5, 2023) (precedential) (3-0); Patent No. 8,048,032; RE45,380; RE45,776
- A party having access to a competitor’s product and then making a substantially similar product infers copying;
- Strong objective evidence including copying, industry praise, and significant commercial success can outweigh prima facie arguments of obviousness.
- Modifying the device of a prior art reference in a manner that would undermine a purpose it shares with the challenged claims counsels against a motivation to make such modifications.
- Objective evidence of non-obviousness exclusively relating to features known in the art may be insufficient to overcome a finding of obviousness even if those features are not necessarily well-known.
- The PTAB may decline to consider an argument presented in a reply that was not previously disclosed in the petition.
- The construing of a prior art teaching from the perspective of a POSITA can result in a logical inference even if such a conclusion is not explicitly disclosed.
- The specification must enable the full scope of the invention defined in the claims.
- When an appellant argues claim rejections as a group, the board can select a single claim to review as representative.
- An obviousness analysis relying on inherency in the prior art to establish the existence of a claim limitation requires a showing that the limitation is “necessarily present” or “the natural result of the combination of elements explicitly disclosed by the prior art.”
- Dismissal of an action for failure to prosecute will not prevent a substituted plaintiff from being considered a “party” for appellate purposes.
- The same standards govern inventorship challenges for utility patents and design patents.
- While the named inventors are presumed correct, a district court may order correction of inventorship when it determines that an inventor has been erroneously omitted from a patent, but an alleged joint inventor’s testimony standing alone is insufficient and needs corroboration.
- Corroborating evidence of inventorship may take many forms, including contemporaneous documents, physical evidence, circumstantial evidence, and oral testimony of someone other than the alleged inventor.
