Rotary Tablet Press Patents: Who Leads, Where the Gaps Are 2026
Rotary Tablet Press Patents: Mapping Who Holds the Claims
81.5% concentration. The top 5 assignees combine for 53 of 65 records in scope — this field is held by a small group, not spread across a long tail. Filings rose from zero in 2017 to a peak of 14 in 2023, then fell to 4 by 2024 (a -60% change from 2021's 10 filings) before the partial, still-incomplete 2025-2026 years. Treat the tail end as undercounted rather than as a genuine slowdown.

Common questions about rotary tablet press patents
Who are the leading patent holders in rotary tablet press technology?
The ranking covers 48 companies, but activity is heavily concentrated: the leading assignee alone holds 19 of the 65 records in scope, and the top 5 assignees combined hold 53 records, or 81.5% of the field. That concentration means new entrants are filing directly alongside a small number of established portfolios rather than into a fragmented market. The top 10 combined reach 93.8% of all records, leaving only a thin long tail of single-filing entrants beyond that point.
Is filing activity for rotary tablet press patents growing or slowing?
Filing peaked at 14 records in 2023 and fell to 4 by 2024, a -60% change from the 10 records filed in 2021. That reads as a real pullback for the 2021-2024 window, since those years are past the typical eighteen-month publication lag. The 2025 and 2026 figures are still incomplete and should not be read as confirming a continued decline until more data publishes.
Which sub-technologies get the most patent claims in this space?
B30B, the general presses classification, appears in 86.2% of the 65 records, making core press mechanics by far the most heavily claimed area. Containers for medicine (A61J) and shaping of plastics (B29C) follow at 41.5% and 35.4% respectively. Sterilising and disinfecting (A61L) and therapeutic activity of compounds (A61P) each appear in only one record, marking them as effectively open ground relative to the press-mechanics core.
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 Rotary Tablet Press Technology covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
