Wiped Film & Short Path Evaporation Patents: Leaders & Trends 2026
Wiped Film and Short Path Evaporation Patents
Filing has cooled from its 2020 peak. 161 records that year, and filings fell -58% from 2021 (120) to 2024 (50), the last year with complete publication data. Filings ran from 64 records in 2017 to a peak of 161 in 2020, then declined to 50 by 2024 — a -58% drop across the 2021-2024 span. That is a genuine slowdown in a year range that has finished publishing, not an artifact of the lag; 2025 and 2026 figures should be read as still filling in.

Common questions on this landscape
Who holds the most patents in wiped film and short path evaporation?
The leading assignee in this dataset holds 168 of the 2,542 records in scope, which is 6.6% of the field on its own. The top 5 assignees combined reach 19.1% and the top 10 reach 28.9%, so even the leader is far from a controlling position. The remainder of the 100 ranked assignees form a long tail of occasional filers, which suggests the underlying equipment is treated as widely accessible rather than tightly held.
Is patent filing in this field growing or shrinking?
Filing peaked in 2020 at 161 records and then declined, with 2021 (120) to 2024 (50) representing a -58% drop across a fully-published span. 2024 is the most recent year with complete publication data, so this decline is a real trend rather than a lag artifact. Figures for 2025 and 2026 are still filling in because publication typically lags filing by around 18 months, so they should not yet be read as continuing the same slope.
What industries actually use wiped film and short path evaporation patents?
The IPC composition shows the technology spread across bulk organic chemistry (C07C, 28.5% of records), separation process engineering (B01D, 17.5%), fatty oil and lipid processing (C11B, 14.9%), and pharmaceutical preparations (A61K, 13.5%), with heterocyclic chemistry, fatty acids, condensation polymers and catalysis all represented as well. Because a single record often carries multiple IPC codes, these shares add up to well over 100% of the 2,542 records rather than partitioning them. That spread indicates the hardware is a shared purification tool across several downstream industries rather than being owned by any one of them.
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 Wiped Film and Short Path Evaporation 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.
