PSA Label Adhesive Patents: Who Leads, Where the Gaps Are 2026
Pressure-Sensitive Adhesive Chemistry for Labels: Patent Landscape 2026
One leader, then a long tail. The top-ranked assignee sits at 65 records against a fifth-place count of 6 and a tenth-place count of 3 — a steep drop-off rather than a gradual one. Filings rose to a peak of 7 records in 2018, then eased; the tracked growth figure of 5 records in 2021 down to 3 in 2024 (-40%) is the most recent span that can be read as complete, since 2025 onward is still filling in.

Common questions about PSA label adhesive patents
Who holds the most patents in pressure-sensitive adhesive chemistry for labels?
One assignee leads the ranked field with 65 records, well ahead of the fifth-ranked company at 6 and the tenth-ranked company at 3, out of 34 ranked assignees total. That gap indicates a broad, long-standing claim position rather than a recent surge. The rest of the field files far less frequently, which is typical in adhesive chemistry where formulation know-how is often kept as trade secret rather than patented.
Is patent filing in PSA label adhesives growing or slowing?
Filing peaked in 2018 at 7 records and had declined to 3 records by 2024, down from 5 in 2021 — a -40% change over that three-year span. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by about eighteen months, so it is too early to call the current trend a continued decline. The honest read is that activity has cooled from its 2018 high but the most recent data is not yet settled.
What technology areas do these patents actually claim?
Almost all records, 92.9% of the 113 in scope, carry a C09J adhesives classification, with addition-polymer chemistry (C08F) present in 35.4%. Smaller shares cover layered laminate structures (B32B, 14.2%), display and signage applications (G09F, 12.4%), and additive, coating and shaping processes each in the 7-8% range. Because a single record can carry multiple IPC codes, these percentages add up to more than 100% and should not be read as a strict breakdown of the field.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Pressure-Sensitive Adhesive Chemistry for Labels covering 2015–2026, data cut-off 2026-07-31.
