Prior art

I will now search the USPTO database for US patent 11799131 to identify its prior art citations.
Prior art is any evidence that an invention was publicly known or available before the effective filing date of a patent application. This can include existing patents, publications, or products, and is used by the USPTO to determine if an invention is novel and non-obvious under 35 U.S.C. §§ 102 and 103.

US Patent 11799131: Electrolyte and electrochemical device

Publication date: 2023-10-24
Filing date: 2022-08-11
Priority date: 2018-09-21

To determine which claims each reference potentially anticipates under 35 U.S.C. § 102, a detailed claim-by-claim analysis against the disclosures of each prior art document would be required. This level of analysis often involves examining the prosecution history (the communications between the patent applicant and the USPTO) to understand how the claims were defined and distinguished from prior art during the examination process. Without access to the full prosecution history and a detailed comparison of each claim element to the prior art, it is not possible to definitively state which specific claims are anticipated.

However, based on the information available, here are the prior art references cited in US Patent 11799131:

• U.S. Pat. No. 11,522,222

  • Full Citation: U.S. Pat. No. 11,522,222
  • Publication/Filing Date: This patent is identified as a continuation of U.S. application Ser. No. 17/064,782, which became U.S. Pat. No. 11,522,222. The filing date for application Ser. No. 17/064,782 would be needed for a precise prior art date. However, the priority date of US11799131B2 is 2018-09-21, so any patent or application with an effective filing date before this would be considered prior art.
  • Brief Description: US11799131B2 is a continuation application of U.S. Pat. No. 11,522,222, meaning it likely shares a significant amount of its disclosure and claims a priority date back to an earlier application. As such, it would cover similar technology related to electrolytes and electrochemical devices, likely involving dinitrile compounds, trinitrile compounds, and propyl propionate.
  • Potential Anticipated Claim(s) under 35 U.S.C. § 102: Given that this is a parent application, it is highly likely to anticipate many, if not all, of the claims of US11799131B2 under 35 U.S.C. § 102, depending on the specific differences in claim scope between the two patents. Continuation applications typically claim similar subject matter.

• U.S. Pat. No. 10,833,363

  • Full Citation: U.S. Pat. No. 10,833,363
  • Publication/Filing Date: This patent is identified as a continuation of U.S. application Ser. No. 16/211,853, which became U.S. Pat. No. 10,833,363. The filing date for application Ser. No. 16/211,853 would be needed for a precise prior art date. The priority date of US11799131B2 is 2018-09-21.
  • Brief Description: US11799131B2 is also a continuation of U.S. Pat. No. 10,833,363, indicating a shared inventive lineage. This patent would also likely relate to electrolytes and electrochemical devices with similar chemical compositions, such as dinitrile, trinitrile compounds, and propyl propionate, and their use in such devices.
  • Potential Anticipated Claim(s) under 35 U.S.C. § 102: Similar to U.S. Pat. No. 11,522,222, as a parent application, U.S. Pat. No. 10,833,363 is highly likely to anticipate many, if not all, of the claims of US11799131B2 under 35 U.S.C. § 102, depending on the specific differences in claim scope.

• China Patent Application No. 201811108529.X

  • Full Citation: China Patent Application No. 201811108529.X
  • Publication/Filing Date: Filed on 2018-09-21. This is the priority date claimed by US11799131B2.
  • Brief Description: This Chinese patent application is the earliest priority document for US11799131B2. It would contain the foundational disclosure for the electrolyte composition (dinitrile compound, trinitrile compound, and propyl propionate) and its application in electrochemical devices, as well as details on electrode compaction densities.
  • Potential Anticipated Claim(s) under 35 U.S.C. § 102: As the priority document, this Chinese patent application would contain the initial disclosure of the invention. Any claims in US11799131B2 that are directly and identically disclosed in this Chinese application and benefit from its priority date would not be anticipated by this specific reference under 35 U.S.C. § 102 (assuming proper priority claim). However, if any claims in US11799131B2 introduce new subject matter not present in the Chinese application, those new aspects could potentially be anticipated by other prior art dating before the filing date of US11799131B2 (2022-08-11), but not by the Chinese application itself.

• U.S. Pat. No. 9,812,739B

  • Full Citation: U.S. Pat. No. 9,812,739B
  • Publication/Filing Date: The full publication/filing dates for this patent would need to be retrieved from the USPTO database.
  • Brief Description: This patent is incorporated by reference for the preparation techniques of anode and cathode materials. Specifically, it is referenced for methods of preparing anode materials (including carbonaceous, silicon-carbon, alloy, or lithium-containing metal composite oxide materials) and cathode materials (sulfide, phosphate salt, lithium-transition metal composite oxide).
  • Potential Anticipated Claim(s) under 35 U.S.C. § 102: Claims in US11799131B2 that describe the general preparation or composition of electrodes, to the extent that these aspects are explicitly and entirely disclosed in U.S. Pat. No. 9,812,739B, could be anticipated. However, US11799131B2's novel contribution lies in the specific electrolyte composition and the relationship between electrode compaction densities, rather than the general methods of electrode preparation. Therefore, U.S. Pat. No. 9,812,739B would likely serve as prior art for the conventional aspects of electrode construction but would not necessarily anticipate the novel features of the electrolyte or the specific compaction density relationships claimed in US11799131B2.
