The assignee ranking in this dataset is concentrated among a small group of Korean and Chinese display manufacturers, including Samsung Display, LG Display and BOE Technology Group, with BOE's affiliated entities also appearing as a strong co-filing pair. That said, several of these same companies show zero or sharply reduced filings in the most recent year, so historical volume leadership does not necessarily indicate who is filing most actively today. Anyone assessing competitive position should look at both the total family count and the recent-year momentum figures rather than either alone.

Filings rose from 128 in 2017 to a peak of 277 in 2020, then fell through 139 at the 2022 midpoint down to 11 in the latest partial year. This pattern is typical of a technology area where the foundational mechanical claims, such as bending radius control and cover window construction, were staked out during the filing ramp and later years shift toward narrower refinements. It is also worth remembering that publication lags filing by roughly 18 months, so the most recent one or two years in any chart will understate true filing activity.

That filing, from Samsung Display, claims a cover window structure built from a base film, a support layer, and a bead layer whose beads partially protrude from the surface, with a binder holding the beads in place. It is a materials and structural claim over a specific way of building the outer protective layer of a flexible display, not a claim over cover windows generally. Anyone designing a competing cover window would need to confirm whether their bead, binder or layer arrangement falls inside or outside this specific structure.

Relative to the dense claim coverage in core display and semiconductor subclasses like G09F and H01L, areas such as hinge-integrated neutral plane structures, multi-fold crease self-healing coatings, and rollable-specific flexible encapsulation barriers show lower filing density in this dataset. Lower density suggests fewer existing claims to work around, but it does not mean the underlying engineering problem is unsolved or that no blocking art exists elsewhere. A proper freedom-to-operate check against the specific claim language is still necessary before filing or launching in any of these branches.

The United States receives the largest number of filings in this dataset at 743, ahead of Europe at 240, China at 205, and South Korea at 176, with WIPO PCT and India contributing smaller shares. This spread means that clearing a flexible display product for global launch typically requires checking multiple jurisdictions rather than relying on a single office's records. The US total also reflects that many international applicants file there as a primary or defensive market regardless of where they are headquartered.
