The leading assignee in this dataset holds 1,700 of the 10,514 records in scope, well ahead of the rest of the ranked field. The top five combined hold 4,510 records, or 42.9% of all records, and the top ten extend that to 53.6%. After the top few names the ranking thins into a long tail across the remaining ranked companies, so most of the competitive weight sits with a small group rather than being evenly spread.

Filing has slowed markedly since a 2017 peak of 841 records, falling to 40 in the most recent, still-partial year, with a 2022 midpoint of 244 confirming the decline is not a single-year anomaly. Publication typically lags actual filing by around 18 months, so the very newest year will always understate true activity, but the multi-year downward trend predates that lag. Several of the most active historical filers also show negative year-on-year momentum recently, reinforcing the same signal.

H01L, covering semiconductor devices generally, appears on 53.1% of the 10,514 records in scope, meaning claim space around device structure is densely occupied. That density reflects how much prior art exists in a given claim area, not how mature or exhausted the underlying technology is — new approaches can still be patentable if they differ structurally from what is already claimed. Because H10K (organic semiconductors) and G09G (display driving) also cover roughly a third of records each, most filings in this space combine device, material and driving-circuit claims rather than sitting in one class alone.

Classes with a smaller share of the 10,514 records, such as C09K (materials, 5.6%) and C07D (heterocyclic compounds, 3.7%), sit well below the dominant H01L, H10K and G09G classes, suggesting thinner coverage in specific material and chemistry sub-areas relative to the core device and driving claims. Variable pixel-density driving for foveated or power-aware displays, illustrated by the representative Google filing in this dataset, is another area where the claim approach looks less crowded than fixed-pitch pixel-structure claims. Any white-space assessment should still be confirmed against live claim scope, not classification share alone.

The United States receives more filings in this dataset than any other office, at 5,721 records, followed by the European Patent Office at 1,522 and China at 817; WIPO/PCT filings total 674. That ordering generally reflects where applicants judge commercial risk and enforcement value to be highest for this technology, though it is a count of where filings were made, not a recommendation independent of your own commercial footprint. UK (400) and Austria (316) filings form a smaller but still notable secondary tier.
