DED In-Situ Monitoring Patent Snapshot 2026
The patent corpus for directed energy deposition (DED) in-situ monitoring is at its earliest stage, with a single family on record filed by Rolls-Royce in 2024 under U.S. jurisdiction. The field is effectively open, and the sole filing to date signals an emerging proprietary interest rather than an established assignee snapshot.
Rolls-Royce holds the only recorded position in a nascent field
A single patent record defines the current evidence snapshot for DED in-situ monitoring, attributed to Rolls-Royce Corp as the top-ranked applicant. The top five filers account for all activity among the ranked applicants visible in this query, reflecting the extreme youth of this space.
There is no meaningful tier gap to analyze because no second tier yet exists. Rolls-Royce Corp and Rolls-Royce PLC together represent the full competitive footprint captured in the evidence, each with one patent record.
| # | Applicant | Patent records | Share |
|---|---|---|---|
| 1 | Rolls-Royce Corp | 1 | |
| 2 | Rolls-Royce PLC | 1 |
Rolls-Royce’s sole filing under both powder metallurgy and additive manufacturing classification codes signals an intent to protect process-monitoring integration within its DED manufacturing workflow, consistent with the company’s aerospace component repair and fabrication interests.
The most recent period is subject to publication lag, meaning additional filings from 2024 onward may not yet be visible in the corpus. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2024 filing defines the trend; IPC coverage spans powder metallurgy and additive manufacturing
Annual filing activity across the ten-year window shows no recorded output from 2017 through 2023, with one record appearing in 2024. The technology composition is equally concentrated, split between two IPC branches.
Annual filing trend
Zero filings are recorded from 2017 to 2023; a single patent record appears in 2024, with nothing yet visible in 2025 or 2026. Given standard publication lag of 18–24 months, 2024 and beyond remain materially under-counted and should not be read as a plateau.

The sole filing is classified equally under B22F (Powder metallurgy) and B33Y (Additive manufacturing / 3D printing), reflecting the hybrid process-material nature of DED in-situ monitoring and confirming that no other IPC branches have yet been claimed in this corpus.

An additive manufacturing system includes an energy delivery device configured to deliver energy to a build surface of an additively-manufactured component being manufactured to form a melt pool in the build surface of the component. The system further includes a powder delivery device, a melt pool monitor configured to observe the melt pool, and a… (excerpt from the patent abstract)
Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Rolls-Royce Corp
Rolls-Royce Corp holds one patent record in the DED in-situ monitoring corpus, co-filed with its U.K. sister entity. Its technology focus is concentrated in B22F 10, B22F 12, and B22F 5 — all powder metallurgy subclasses — indicating a process-control orientation tied to metal additive manufacturing. Momentum is classified as a new entrant with no prior-period baseline.
patent records: 1Rolls-Royce PLC
Rolls-Royce PLC holds one patent record, identical in IPC coverage to Rolls-Royce Corp (B22F 10, B22F 12, B22F 5), reflecting the joint-applicant nature of the single filing. As with its corporate counterpart, momentum is classified as a new entrant. The intra-group structure suggests coordinated global IP strategy rather than independent parallel programs.
patent records: 1Frequently asked questions
The current evidence captures one patent family in scope. This reflects the nascent state of the field and publication lag — filings from 2024 onward may not yet be fully visible in the corpus.
Rolls-Royce Corp and Rolls-Royce PLC are the only applicants captured in the evidence, each with one patent record. Both are entities within the Rolls-Royce corporate group and co-filed the single record.
The filing is classified under B22F (Powder metallurgy) and B33Y (Additive manufacturing / 3D printing), with subclass emphasis on B22F 10, B22F 12, and B22F 5.
The single patent record on file is registered in the United States only. No international counterparts appear in the current evidence.
Based on available evidence, the space is highly open. A single patent record exists, and adjacent IPC branches such as G01N (materials testing) and G05B (control systems) are entirely unrepresented in the corpus.
The representative patent on record is US20250276383A1, attributed to Rolls-Royce entities and published in 2025 based on its application number structure.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
