Beverage Carbonation Patents: Who Leads, Where the Gaps Are 2026
Beverage carbonation and aseptic filling patents: who holds the claims and where the field is still open
72.2% of the field sits with five filers. The top five assignees combined account for 65 of the 90 records in scope — a concentrated core rather than a fragmented one. Filings were negligible through 2017 and stayed low until 2021 (2 records), then rose to 7 by 2024 — a 250% increase — with a peak of 12 in 2023. Read 2025 and 2026 as incomplete rather than a slowdown.

Common questions about this patent landscape
Who holds the most patents in beverage carbonation and aseptic filling?
The dataset behind this landscape ranks 29 companies, with the leading filer holding 20 of the 90 records in scope. The top five filers combined hold 65 records, or 72.2% of everything in scope, which means a small group of companies controls most of the documented claim space. Beyond tenth place, filing counts drop to single or low-double digits, so freedom-to-operate work should prioritise the leading names first.
Is patent filing activity in beverage carbonation still growing?
Yes, based on complete years: filings rose from 2 records in 2021 to 7 in 2024, a 250% increase, with a peak of 12 records in 2023. Because publication lags filing by roughly 18 months, 2025 and 2026 figures in any dataset are still filling in and should not be read as a slowdown. The trend through the last complete year points to active, not declining, interest.
What does US4025655A actually cover, and does it block new filings?
US4025655A, assigned to The Procter & Gamble Company, covers beverage carbonation devices that use carbon dioxide-containing molecular sieves which release CO2 on contact with an aqueous solution. It is one of the most-cited records in this dataset, which signals that later carbonator-mechanism filings have had to design around or cite it. Anyone filing a claim built on solid-media CO2 release for carbonation should review its claim scope specifically, rather than assuming a general carbonation patent covers different mechanics.
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 Beverage Carbonation and Aseptic Filling 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.
