Intelligent Barrier Packaging Patent Snapshot 2026
Intelligent barrier packaging is a nascent, fragmented field with 14 patent families in scope, led by Agency for Science, Technology and Research (A*STAR) with 3 patent records. Annual volume has eased from its 2021 peak, though recent new entrants from India and China signal continued distributed interest.
A*STAR leads a highly fragmented field with no dominant incumbent
Agency for Science, Technology and Research (A*STAR) holds the top position with 3 patent records, followed by Saudi Arabian Oil Company with 2. No single applicant commands a decisive share — the remainder of the ranked applicants each hold a single patent record.
The top five filers account for 42% of the ranked applicants visible in this query’ combined total, a moderate concentration level for such a small corpus. The tier gap between the leader and all others is narrow, meaning no applicant has yet established a defensible patent moat in this space.

A*STAR’s position, rooted in layered laminates, containers, and material analysis, reflects a research-institute orientation rather than a commercial incumbent. Saudi Arabian Oil Company’s presence signals industrial interest in barrier materials with a polymer-composition emphasis.
The most recent 18–24 months of filings are likely under-counted due to patent publication lag; observed recent-period figures should be treated as a floor, not a ceiling. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity peaked in 2021 and has since eased; containers and laminates dominate the technology mix
The filing trend and technology composition charts together reveal both the pace of activity and where technical effort has concentrated across IPC branches.
Annual filing trend
Annual filings reached a local peak of 3 records in 2021, dropped to 1 in 2022–2023, then recovered to 2–3 in 2024–2025 before a single record in 2026. The 2025–2026 figures are subject to publication lag and likely understate true activity; the overall trajectory is best read as post-peak oscillation at low volume rather than a clear directional trend.

B65D (Containers and packaging) and B32B (Layered products and laminates) are the two visible branches, reflecting that most work combines structural container design with multi-layer film engineering. A23L (Foods and non-alcoholic beverages) and G01N (Material analysis and testing) form a secondary cluster, indicating sensor and freshness-indicator integration. A further 13 branches each carry only a single record, illustrating broad but shallow technical diversification.

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.
Agency for Science, Technology and Research (A*STAR)
A*STAR holds 3 patent records — the highest in the corpus — with technical emphasis spanning layered laminates (B32B 27), container design (B65D 81), and optical material analysis (G01N 21). This breadth suggests a platform-level approach integrating barrier structure with in-package sensing. Momentum data does not record A*STAR among the most recent new entrants, implying its filings are concentrated in earlier periods.
patent records: 3Saudi Arabian Oil Company
Saudi Arabian Oil Company holds 2 patent records, focused on layered laminates (B32B 15, B32B 27) and polymer compositions (C08L 33), pointing to a materials-science approach to barrier performance. This emphasis on polymer formulation differentiates it from A*STAR’s sensing-integrated strategy. Momentum data does not list it among the most recent entrants, suggesting its activity predates the current period.
patent records: 2Frequently asked questions
The corpus contains 14 patent families in scope based on the PatSnap Eureka dataset used for this analysis.
Agency for Science, Technology and Research (A*STAR), based in Singapore, leads with 3 patent records, ahead of Saudi Arabian Oil Company with 2.
India is the leading filing jurisdiction with 5 patent records, followed by China with 3 and Singapore with 2.
The evidence places the field in a decline stage, with annual filings easing back from a peak in 2021. The recent-window growth figure is -20%, though publication lag means the most recent periods are likely under-counted.
B65D (Containers and packaging) and B32B (Layered products and laminates) are the two most represented branches, followed by A23L (Foods and non-alcoholic beverages) and G01N (Material analysis and testing).
No co-applicant relationships are recorded in the evidence. All active filers appear to be working independently, with no consortia or joint-filing partnerships detected.

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.
