Field Overview
What this landscape covers
Laser cladding control sits at the intersection of laser welding, coating deposition and process feedback: claims combine a laser cladding or laser-powder-fusion process under IPC B23K26 with a control or regulation element — closed-loop feedback on powder injection, real-time deposit-height monitoring, or a mechanical feature that shapes gas or material flow during irradiation. The dataset in scope holds 135 published records filed between 2015 and the 2026 cut-off.
Most records carry a welding classification (B23K, 95.6%) alongside a coating or surface-deposition classification (C23C, 25.9%), which reflects the field's core use case: repairing or building up metal surfaces — turbine blades, valve seats, tooling — with a laser-fed powder process that is monitored or regulated in real time rather than run open-loop.

Filing Data
Filing trends and technology composition
The dataset covers 135 published records from 2015 through the 2026 cut-off, spanning eight IPC subclasses and six major receiving offices.
Filings peaked in 2021, then pulled back
Annual filings rose from 1 in 2017 to a peak of 13 in 2021, then fell to 3 by 2024, a -77% change over that three-year span. Publication lags filing by roughly 18 months, so 2025 and 2026 figures are still filling in and should not be read as a continued decline.
Publication lags filing by roughly 18 months, so 2025 onwards are still filling in. Growth rates on this page therefore end at 2024; running them to the last bar would understate the field.
Welding and coating classes dominate, control systems overlap a tenth of records
B23K (welding, soldering & brazing) appears on 95.6% of the 135 records, confirming this is fundamentally a welding-process dataset with cladding control as the differentiating claim element. C23C (coating & surface deposition) reaches 25.9%, while G05B (control & regulating systems) sits at 10.4% — the smaller share of a dedicated control-systems classification suggests most control claims are drafted as process steps within a welding claim rather than as standalone control-system claims.
Shares are the percentage of the 135 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

US10245680B2 — Cladding method for valve seat and production method for cylinder head
TOYOTA JIDOSHA KABUSHIKI KAISHA
A cladding method for a valve seat in a cylinder head blank forms a cladding layer by irradiating metal powder in an annular countersunk groove with a laser beam. A gas-flow regulating wall projects from the groove toward the combustion chamber side, and shielding gas is directed by that wall from the inner to the outer side during irradiation.Granted 2019-04-02 to Toyota Jidosha; scoped to engine valve-seat geometry rather than laser cladding control generally.

What the filing pattern tells a strategy team
Three figures from this dataset matter more than the rest for anyone deciding where to file next or who to watch.
Concentration
67.4%
of 135 records held by top 10
A tight leadership group, then a long tail
The top 10 of the 43 ranked assignees account for 91 of 135 records. That leaves 33 assignees splitting the remainder, mostly single- or double-digit filers, so freedom-to-operate work needs to check the leaders first but cannot stop there.
Assignee ranking, 135 records
Filing momentum
-77%
2021 to 2024 (13 → 3 filings)
A 2021 peak, then a real but overstated drop
Filings hit a peak of 13 in 2021 and fell to 3 by 2024. Because publication lags filing by roughly 18 months, some of that drop is an artefact of incomplete recent-year data rather than a confirmed retreat from the technology.
Filing trend, 2017-2026
Claim structure
10.4%
of records classified under G05B
Control logic rides inside welding claims
With B23K present on 95.6% of records but G05B on only 10.4%, most cladding-control inventions are claimed as a feedback step within a welding process rather than as an independent control system, which shapes how a design-around has to be drafted.

Only 8 co-assignee pairs appear across the dataset, and the strongest is a two-inventor pairing on 7 shared records, so most prosecution here is done by a single assignee rather than through joint filings.

Frequently Asked
Questions practitioners ask about this field
The assignee ranking covers 43 companies across the 135 records in scope, with the leader holding 18 records. The top 5 combined account for 55 records, 40.7% of all 135 records in scope, and the top 10 combined reach 91 records, 67.4% of the total. That leaves a long tail of single- or double-digit filers, so the field is concentrated at the top but not dominated by a single entity.
Most records in this dataset combine a B23K welding/cladding process step with a feedback or regulation element — closed-loop control of powder injection, real-time image-based monitoring of deposit height, or a mechanical feature such as a gas-flow regulating wall that shapes the cladding outcome during irradiation. Very few claims are pure control-systems claims in isolation: only 10.4% of records carry a G05B control-and-regulating-systems classification, meaning the control logic is usually claimed as part of the welding process rather than as a standalone system.
Filings rose to a peak of 13 in 2021 and fell to 3 by 2024, a -77% change over that span. Because publication typically lags filing by around 18 months, the 2025 and 2026 figures in any dataset are necessarily incomplete, so the visible drop after 2021 partly reflects filings that have not yet published rather than a confirmed slowdown in R&D activity.
No. US10245680B2 is scoped narrowly to a cylinder-head valve seat formed inside an intake or exhaust port, where a gas-flow regulating wall projects from an annular countersunk groove to direct shielding gas during laser irradiation. It blocks that specific engine-component geometry and gas-flow mechanism, not laser cladding control generally — cladding processes for turbine blades, tooling repair or other components with different gas-flow arrangements fall outside its literal claims.
The spraying/atomising overlap (B05B, 8.1% of the 135 records) and the foundry-integration classes (B22C and B22D, each 6.7%) are comparatively thin next to the coating-outcome overlap at C23C (25.9%), suggesting spray-parameter-based control loops and mould/casting-quality feedback are less heavily claimed than deposit-geometry control. Co-assignee activity is also sparse, at 8 pairs total, so joint filings between a cladding specialist and a foundry or materials partner are not yet a crowded strategy.
