Prior art

To identify the most relevant prior art for US patent 11374215, I will access the USPTO database and examine the patent citations.

Here's the most relevant prior art for US patent 11374215, based on the citations within the patent document:

I am unable to directly access and parse the full list of "References Cited" from the USPTO database in real-time within this environment. However, the patent text itself provides a "CROSS REFERENCE TO RELATED APPLICATIONS" section that explicitly lists priority claims, which are crucial for understanding the patent's lineage and its relationship to earlier art. These related applications often contain the foundational work and thus represent highly relevant prior art.

Based on the provided patent text, the following related applications are cited:

1. U.S. patent application Ser. No. 17/353,364

   • Full Citation: U.S. patent application Ser. No. 17/353,364, entitled “Scaffolding Matrix with Internal Nanoparticles”
   • Publication/Filing Date: Filed on June 21, 2021.
   • Brief Description: This is a Continuation of which US11374215 is a continuation. It describes a scaffolding matrix with internal nanoparticles, likely encompassing similar concepts to the granted patent.
   • Potential Anticipation (35 U.S.C. § 102): This application, being a direct continuation, would likely disclose subject matter that could anticipate many, if not all, of the claims of US11374215, particularly Claim 1 and Claim 11, if the scope of the claims in 17/353,364 is substantially similar. It acts as prior art due to its earlier filing date, subject to any intervening prior art events or changes in the claims during prosecution.

2. U.S. patent application Ser. No. 16/419,806

   • Full Citation: U.S. patent application Ser. No. 16/419,806 entitled “Scaffolding Matrix with Internal Nanoparticles”
   • Publication/Filing Date: Filed on May 22, 2019.
   • Brief Description: This is a Continuation of which 17/353,364 is a continuation. It details a scaffolding matrix with internal nanoparticles, building upon even earlier work.
   • Potential Anticipation (35 U.S.C. § 102): Similar to the 17/353,364 application, this earlier continuation would likely anticipate a significant portion of US11374215's claims if the disclosed subject matter is similar. Claim 1 and Claim 11 would be particularly susceptible to anticipation by this earlier filing.

3. U.S. patent application Ser. No. 13/973,943

   • Full Citation: U.S. patent application Ser. No. 13/973,943 entitled “Scaffolding Matrix with Internal Nanoparticles”
   • Publication/Filing Date: Filed on August 22, 2013.
   • Brief Description: This is a Continuation of which 16/419,806 is a continuation. This represents an even earlier stage in the patent family, describing the core invention of a scaffolding matrix with internal nanoparticles.
   • Potential Anticipation (35 U.S.C. § 102): This application is highly relevant as a foundational document. It is very likely to anticipate the fundamental aspects of Claim 1 and Claim 11 of US11374215, given its title and its position in the priority chain.

4. Provisional Application No. 61/693,070

   • Full Citation: Provisional Application No. 61/693,070 entitled “Scaffolding Matrix with Internal Nanoparticles”
   • Publication/Filing Date: Filed on August 24, 2012.
   • Brief Description: This is the earliest priority document in the chain. Provisional applications provide an early filing date for an invention and usually contain a detailed description of the core concepts.
   • Potential Anticipation (35 U.S.C. § 102): As the earliest document establishing priority, this provisional application is the most critical piece of prior art from this family. It would be expected to fully anticipate the core invention as claimed in US11374215, especially Claim 1 (composition) and Claim 11 (method of fabrication), assuming the disclosed subject matter aligns with the independent claims. The claims of US11374215 must be novel over the disclosure of this provisional application.

These related applications are the most direct and relevant prior art because US11374215 claims priority through them, meaning the content of these earlier applications is generally considered prior art against the claims of the later-filed patent. The claims of US11374215 must distinguish themselves from the disclosures within these prior applications to be considered novel.
