Technology Transfer Patents: Who Leads, Where the Gaps Are 2026
Technology Transfer and Comparability Patents: Mapping a Concentrated Field
48.6% sits with five filers. The top 5 assignees combined account for 86 of the 177 records in scope — a field where a handful of programmes set the terms for analytical bridging and comparability claims. Filings rose from zero in 2017 to a peak of 34 in 2022, then fell to 9 by 2024 — a 25% drop from the 12 filed in 2021. Because publication trails filing by roughly 18 months, the 2025 and 2026 counts are not yet complete and should not be read as confirmation that the decline continues.

Common questions on this landscape
What counts as a technology transfer or comparability patent in bioprocess scale-up?
In this dataset it means filings that claim methods or systems for moving a biologic manufacturing process between sites or scales while proving the output is equivalent — analytical bridging, process parameter mapping, equipment difference assessment, hold time studies, engineering runs and the acceptance criteria used to judge success. These are distinct from process development patents because they focus on the comparability case itself rather than the underlying manufacturing step. Most of the 177 records in scope sit inside biologics or cell/gene therapy programmes rather than small-molecule or general industrial manufacturing.
Who are the leading filers in technology transfer and comparability patents?
The ranked list covers 71 companies, with the leader holding 19 records and a steep drop to 14 at fifth place and 6 at tenth. The top 5 assignees combined hold 86 of the 177 records in scope (48.6%), and the top 10 extend that to 75.7%. Below that group the list thins into a long tail of assignees with only one or two filings each, so competitive attention should focus on the small group at the top rather than the full list.
Is filing activity in this space growing or slowing?
Filing peaked at 34 records in 2022 and had fallen to 9 by 2024, a 25% decline from the 12 filed in 2021. That said, publication typically lags filing by around 18 months, so the 2025 and 2026 counts in this dataset are still incomplete and should not yet be read as a confirmed downward trend. Treat 2024 as the most recent year with a reliable count.
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 Technology Transfer and Comparability 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.
