Obviousness

I am unable to provide a comprehensive obviousness analysis under 35 U.S.C. § 103 because I lack the detailed descriptions and full teachings of the cited prior art patents (US5138481A, US5365365A, US20040150867A1, US20160202590A1, US20170298682A1) [cite: "I am unable to retrieve the abstracts and detailed descriptions for the cited prior art patents using the available search tools. Therefore, I cannot provide a brief description for each reference or assess which claims of US10539851 they potentially anticipate under 35 U.S.C. § 102."].

A proper obviousness analysis requires an understanding of what each prior art reference teaches, so that one can determine:

1. What claims or elements of US 10,539,851 are present in the prior art.
2. Why a person having ordinary skill in the art (PHOSITA) would have been motivated to combine specific references.
3. How such a combination would render the claims of US 10,539,851 obvious, providing a reasonable expectation of success.

While the titles of some references, such as "Electrochromic system with measurement of charge to be transferred" (US5365365A) [cite: "US5365365A - Electrochromic system with measurement of charge to be transferred"] and "Driver for electrochromic glass unit" (US20160202590A1) [cite: "US20160202590A1 - Driver for electrochromic glass unit"], suggest relevance to the core concepts of charge control and driving forces in US 10,539,851's claims (e.g., claims 1, 8, and 15), inferring a complete teaching and motivation to combine solely from titles would be speculative and not meet the standard for an obviousness analysis. Without access to the full content of these documents, I cannot accurately identify specific combinations, articulate the motivation for a PHOSITA to combine them, or explain how such combinations would lead to the claimed invention with a reasonable expectation of success.
