The dataset used for this landscape contains 12 published patent families matching deposition process automation, automated production line, or roll-to-roll automation claims tied to CIGS or copper indium gallium selenide thin-film technology. That is a small, concentrated corpus rather than a broad field, so any single filing carries proportionally more weight than it would in a larger technology area. Filing activity peaked in 2018 with nine records and has not repeated that volume since.

Filing in this corpus is spread across a small number of assignees rather than concentrated in one dominant player, and none of the tracked assignees show any filings in the most recent year covered by the data. This is consistent with a field that saw a short burst of interest around 2018 rather than sustained, ongoing investment by a fixed set of leaders. Anyone assessing competitive position here should look at the assignee ranking directly rather than assume a stable leader exists.

Coverage is uneven. Semiconductor device claims (H01L) and photovoltaic generation claims (H02S) account for most of the corpus, but automated control and regulating systems (G05B) appear in only one family out of twelve. That means the physical roll-to-roll handling and module structure are more thoroughly claimed than the automated process-control layer that would govern deposition rate, web speed, or in-line quality feedback.

A concentrated spike followed by a drop to zero by 2022 usually signals that a specific technical approach was tested in the patent record and then not pursued further, rather than a technology maturing into steady-state filing. For a new entrant, that pattern is worth investigating claim-by-claim: it can mean the approach hit a technical or commercial dead end, or that filers shifted their automation claims into adjacent categories not captured by this search string. Either way, absence of recent filings is not the same as absence of active development, given the roughly 18-month lag between filing and publication.

US20240332440A1, assigned to SOLARPAINT LTD., claims a rollable photovoltaic awning or canopy with specific physical limits: a rolled-in diameter under 30 centimeters, a rolled-out area of at least 2 square meters, and durability of 1,000 roll/unroll cycles with no more than 15 percent efficiency degradation. A product that falls inside all three of those bounds in a similar awning or canopy form factor is the configuration most likely to need a freedom-to-operate review. Products built around CIGS deposition equipment or automated manufacturing lines rather than the finished rollable form factor sit outside what this claim covers.
