The dataset's ranking covers 30 assignees, with the single leader holding 7 of the 62 records in scope and the top 5 combined accounting for 50.0% of all records. That leaves a long tail of entrants with one or two filings each, so the field is led but not locked up by any one player. A newcomer assessing competitive risk should look at the leader's specific claim scope rather than assume the whole space is blocked.

Filings rose from 7 in 2021 to 12 in 2024, a 71% increase, with 2023 the peak year recorded so far at 12. Counts appear to taper after 2024, but that reflects the roughly 18-month lag between filing and publication rather than an actual drop in activity. Anyone tracking this space should treat the last one to two years of any chart as a floor, not a ceiling.

Most records carry claims in G06F (electric digital data processing, 40.3% of records) and G16C (computational chemistry, 37.1%), with G06N (AI-based computing) close behind at 29.0%. Classes tied directly to physical material testing, such as G01N, appear in only 16.1% of records. That split means the bulk of claim activity sits on the data-processing and modelling pipeline wrapped around a material, not on the material's characterisation itself.

Branches such as image-to-property prediction pipelines, synthesis-condition optimisation loops and solid-state electrolyte discovery workflows show comparatively thin filing density against the dense G06F/G16C core. These are documented, real sub-areas within the 62-record dataset rather than speculative categories. A first claim in one of these branches has more room to establish a distinct position than a new filing in the crowded computational-chemistry core.

US20220351504A1, filed by Proterial, Ltd. and published 2022-11-03, claims a specific pipeline: scanning an image of a material, lowering its gradation, generating a virtual image, extracting features, and predicting a material property from those features. It blocks that particular sequence of steps rather than image-based property prediction in general. Alternative feature-extraction methods or prediction architectures that do not follow this exact gradation-reduction-then-virtual-image chain sit outside its literal claim scope, though a full freedom-to-operate check should be run against the claims as issued.

The United States receives the largest share of filings at 30, followed by the EPO route at 14 and the WIPO/PCT route at 7. India, Australia and Canada each see a small number of filings. The pattern suggests applicants are prioritising the US and Europe directly while using PCT more selectively to preserve international options rather than filing everywhere at once.
