Prior art

To identify the most relevant prior art for US patent 10589225, I will search for the cited patents within US10589225B2. The USPTO website provides a "Patent Public Search" tool for this purpose.

Based on the provided patent text, I will specifically look at the "Cited Patents" section (or equivalent, such as "References Cited") to extract the necessary information. I will then analyze each cited patent to determine its potential relevance to the claims of US10589225 under 35 U.S.C. § 102.

Since I do not have direct access to the USPTO database for live querying, I will rely on the information present in the provided patent text, which lists cross-references to related applications and general prior art descriptions.

The provided patent text mentions "CROSS-REFERENCE TO RELATED APPLICATIONS" and specifically states: "This application is a divisional of U.S. patent application Ser. No. 11/209,163 filed Aug. 22, 2005, entitled “Sorbents for the Oxidation and Removal of Mercury”, which claims the benefit of U.S. Provisional Application Ser. No. 60/605,640, filed Aug. 30, 2004, both applications are hereby incorporated herein by reference in their entirety for all purposes."

This indicates that U.S. patent application Ser. No. 11/209,163 and U.S. Provisional Application Ser. No. 60/605,640 are foundational prior art for US10589225.

Additionally, the patent text refers to "co-pending, commonly owned PCT patent application No. PCT/US04/12828, titled “PROCESS FOR REGENERATING A SPENT SORBENT”, which is hereby incorporated by reference in its entirety." This PCT application is also considered prior art, particularly regarding regeneration techniques.

Here is an analysis of these explicitly mentioned prior art documents:

1. U.S. Provisional Application Ser. No. 60/605,640

• Full Citation: U.S. Provisional Application Ser. No. 60/605,640
• Publication/Filing Date: August 30, 2004
• Brief Description: This is a provisional patent application that US10589225 claims the benefit of, meaning it likely contains the earliest disclosed subject matter for many of the inventions claimed in US10589225. Its content would broadly cover "Sorbents for the Oxidation and Removal of Mercury."
• Potential Anticipation (35 U.S.C. § 102): As the priority document, it would likely anticipate many aspects of the independent claims (Claim 1, 13, 22, and 35) if the claimed subject matter was sufficiently disclosed within it. Specifically, it would likely anticipate the core concepts of promoted carbon sorbents for mercury removal, methods of preparation, and methods of use, assuming these were described in adequate detail in the provisional application.

2. U.S. patent application Ser. No. 11/209,163

• Full Citation: U.S. patent application Ser. No. 11/209,163, titled “Sorbents for the Oxidation and Removal of Mercury”
• Publication/Filing Date: August 22, 2005
• Brief Description: This is a non-provisional patent application from which US10589225 is a divisional. It further develops the concepts introduced in the provisional application, describing sorbents and methods for the oxidation and removal of mercury from gas streams.
• Potential Anticipation (35 U.S.C. § 102): As the parent application, it would likely anticipate many or all of the claims of US10589225, provided the claimed subject matter was present in its specification. This would include the promoted carbon sorbent (Claim 1), the method of preparation (Claim 13), the method of mercury reduction with recovery/regeneration (Claim 22), and the method of mercury reduction with size separation (Claim 35), to the extent these were disclosed.

3. PCT patent application No. PCT/US04/12828

• Full Citation: PCT patent application No. PCT/US04/12828, titled “PROCESS FOR REGENERATING A SPENT SORBENT”
• Publication/Filing Date: The filing date is not explicitly stated in the provided text, but the application number "US04/12828" suggests a filing year of 2004.
• Brief Description: This PCT application is incorporated by reference for its description of "PROCESS FOR REGENERATING A SPENT SORBENT." This indicates it details methods for regenerating activated carbon sorbents used for pollution control.
• Potential Anticipation (35 U.S.C. § 102): This PCT application would be highly relevant for anticipating Claim 22, which includes the step of "regenerating the recovered sorbent." It may also be relevant to Claim 35 if regeneration is implied or described in the context of re-injecting sorbent particles. Any specific regeneration techniques claimed in US10589225 would need to be compared against the disclosures of PCT/US04/12828.
