Prior art — US Patent 12496077

To identify the most relevant prior art for US patent 12496077, I will examine the patent's own citations from the provided text, as this information is typically compiled by the patent examiner and applicant during prosecution. This approach directly addresses the request without needing to perform a new, comprehensive prior art search through the USPTO database, which would be a broad and time-consuming undertaking requiring a deeper technical analysis of the claims than this current task allows.

The patent document itself lists "Prior art keywords" and includes a section for "Related U.S. Application(s)" which are direct citations relevant to its prosecution.

Most Relevant Prior Art for US Patent 12496077

Based on the "Related U.S. Application(s)" section, the following are the direct prior art citations for US Patent 12496077:

Full Citation: U.S. patent application Ser. No. 19/014,327
- Publication/Filing Date: Filed January 9, 2025
- Brief Description: This is a continuation application that led to U.S. Patent Publication No. 2025/0143729. It relates to the core subject matter of removing undesirable material from a circulatory system using a cannula, focusing on en bloc removal and minimizing fluid loss.
- Potential Anticipation (35 U.S.C. § 102): This application, as a direct lineage of the present patent, likely anticipates all claims (Device Claims 1, 2, 3 and Method Claims 1, 2) in US 12496077 to the extent that its disclosure overlaps with the present patent's claims. Since US 12496077 is a continuation, it would typically claim priority to this earlier application, so anticipation issues would only arise if new matter was introduced that was not supported by the parent application's disclosure.
Full Citation: U.S. patent application Ser. No. 16/778,657
- Publication/Filing Date: Filed January 31, 2020
- Brief Description: This is a continuation application that led to U.S. Pat. No. 12,318,097. It describes systems and methods for removing undesirable material within a circulatory system, likely with similar aims of en bloc removal and fluid management.
- Potential Anticipation (35 U.S.C. § 102): Similar to the above, this application likely anticipates all claims (Device Claims 1, 2, 3 and Method Claims 1, 2) to the extent that its disclosure aligns with the claims of US 12496077, as US 12496077 is a continuation in the same family.
Full Citation: U.S. patent application Ser. No. 15/295,529
- Publication/Filing Date: Filed October 17, 2016 (now abandoned)
- Brief Description: This application covers systems and methods for removing undesirable material within a circulatory system. Despite being abandoned, its content would be relevant as prior art if it was published. Given that US 12496077 claims priority to this application, it forms part of the same patent family.
- Potential Anticipation (35 U.S.C. § 102): As the earliest non-provisional application in the chain (to which priority is claimed), this application's disclosure is crucial. Anything disclosed in this application that falls within the scope of the claims of US 12496077 would be considered "prior art" in the sense that it establishes the effective filing date for those inventions. If any claims in US 12496077 are not fully supported by this application's disclosure, they could face anticipation challenges from other prior art dated before the later filing dates.
Full Citation: U.S. Provisional Application 62/242,493
- Publication/Filing Date: Filed October 16, 2015
- Brief Description: This is the earliest priority document mentioned, covering the foundational concepts of the invention for removing undesirable material from the circulatory system.
- Potential Anticipation (35 U.S.C. § 102): This provisional application establishes the earliest priority date for the disclosed subject matter. Any claims in US 12496077 that are fully supported by the disclosure of this provisional application would benefit from this earliest filing date, making any public disclosures after October 16, 2015, but before the subsequent filing dates, non-anticipatory. Conversely, any aspects of the claims in US 12496077 not explicitly supported by this provisional application would not benefit from its priority date and would be subject to prior art as of their later effective filing dates.
