Cell-Free Protein Synthesis Patents: Who Leads, Where the Gaps Are 2026
Cell-Free Protein Synthesis Energy Regeneration Patents: Who Holds the Claims
Concentrated at the top. The top 5 assignees together account for 55.8% of all 95 records in scope, and the top 10 for 82.1% — a short list controls most of the filed claim space. Filings ran as high as 27 in 2018 and 20 in 2017, then settled into a much lower and flatter pattern — 2021 and 2024 both sit at 1 record, a 0% change over that three-year span. 2025 and 2026 figures will rise as publication catches up with filing, since publication typically lags filing by around 18 months.

Common questions about this landscape
Who holds the most patents on cell-free protein synthesis energy regeneration?
One assignee leads the ranked list with 15 records, noticeably ahead of the rest of the field — fifth place holds 8 and tenth place holds 4. The top 5 assignees combined account for 55.8% of all 95 records in scope, and the top 10 combined account for 82.1%, so the field is concentrated among a small number of specialist and institutional filers rather than spread evenly. A freedom-to-operate check in this space should start with that short list before widening out to the long tail of single-filing entrants.
Is filing activity in cell-free protein synthesis energy regeneration growing or slowing?
Filing peaked in 2018 at 27 records, well above the 20 seen in 2017, and has since settled onto a much lower plateau. Comparing the last two complete years available, 2021 and 2024 both sit at 1 record, a 0% change over that span, so the honest reading is flat rather than declining. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by around 18 months, so recent-year counts will rise as more records come through.
What patent classes cover cell-free protein synthesis energy regeneration technology?
The two dominant IPC subclasses are C12N (microorganisms and genetic engineering), covering 89.5% of the 95 records, and C12P (fermentation and enzymatic synthesis), covering 85.3%. C07K (peptides and proteins) appears in 35.8% of records, while measurement- and testing-related classes such as C12Q and G01N appear in well under a fifth of records. Because a single record can carry multiple IPC classes, these shares add up to more than 100% and should not be summed together.
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.
